The Medicare Part B Late Enrollment Penalty (LEP) is one of the most consequential and least understood provisions of the Medicare program. A Georgia senior who delays Part B enrollment for three years and does not qualify for an exemption pays a permanent 30% premium surcharge for the rest of their life. At the 2026 standard Part B premium of $191.50 per month, that 30% surcharge adds $57.45 per month, or $689.40 per year, or potentially $13,788 over twenty years of retirement. A five-year delay produces a 50% surcharge: $95.75 per month, $1,149 per year, or roughly $23,000 over twenty years on top of the regular premium. A ten-year delay doubles the standard premium. Many of these penalties could have been avoided if the beneficiary had understood the Initial Enrollment Period (IEP), the Special Enrollment Periods (SEPs), the Section 1839(b)(3) Medicare Savings Program (MSP) Buy-In exemption, or the Equitable Relief procedure for SSA errors.
This guide gives Georgia families the complete picture of the Part B LEP: the federal statutory and regulatory framework under Section 1839(b) of the Social Security Act and 42 CFR 407.20, the mathematical mechanics of the penalty calculation, every qualifying Special Enrollment Period (including the COBRA SEP and its limits, the Working Aged Group Health Plan SEP, the International SEP, the Volcanic Event SEP under MIPPA 2008, the FEHB SEP, the TRICARE SEP, and the IDD/spouse death SEP), the Section 1839(b)(3) Buy-In exemption that wipes the LEP off the bill for Georgia Medicare Savings Program enrollees going forward, the Equitable Relief procedure under Section 1837(h) for SSA mistakes, the Beneficiary Enrollment Notification and Eligibility Simplification (BENES) Act 2020 reforms that took effect in 2023, comparison to the Part A and Part D LEPs, and six worked examples that illustrate typical Georgia LEP scenarios.
Georgia Medicare Part B LEP at a glance. Authority: Section 1839(b) of the Social Security Act (42 USC 1395r(b)) and 42 CFR 407.20. Calculation: 10% of the standard Part B premium added permanently for each full 12-month period of delay beyond the Initial Enrollment Period. Duration: For life, unless removed via Section 1839(b)(3) Buy-In exemption for Medicare Savings Program enrollees, Section 1837(h) Equitable Relief, or original LEP-erasing relief. 2026 standard premium: $191.50 per month. 1-year LEP at 10%: $19.15 per month or $229.80 per year. 3-year LEP at 30%: $57.45 per month or $689.40 per year. 5-year LEP at 50%: $95.75 per month or $1,149 per year. 10-year LEP at 100%: $191.50 per month or $2,298 per year. Initial Enrollment Period: seven months around the 65th birthday or the 25th month of SSDI entitlement. General Enrollment Period: January 1 to March 31 annually, with coverage starting the month after enrollment (per BENES Act 2020). Critical Georgia pathway: Medicare Savings Program approval through DFCS triggers Section 1839(b)(3) Buy-In which exempts beneficiaries from the LEP going forward while enrolled, an often-missed protection for the roughly one in three Georgia Medicare beneficiaries with QMB, SLMB, or QI eligibility. Equitable Relief: available when SSA, CMS, or a federal agency gave incorrect or misleading information that caused the delayed enrollment, filed via Form CMS-L564 or the local SSA office under POMS HI 00805.270. :::
::: callout Key takeaways for Georgia families. First, the Part B LEP is real and permanent: a 3-year delay costs $689 per year in 2026, $13,788 over twenty years; a 10-year delay doubles the Part B premium for life. Second, the safest path is on-time enrollment during the IEP at age 65 (or 25 months of SSDI). Third, Working Aged GHP SEP works for beneficiaries with active employment GHP coverage from large employers (20+) past age 65, with an 8-month enrollment window from the end of active employment. Fourth, COBRA is not active employment coverage and does not extend the GHP SEP: this is the most common LEP trap. Fifth, the Section 1839(b)(3) Buy-In exemption eliminates the LEP for Georgia QMB, SLMB, and QI enrollees, a critical protection for the roughly one in three Georgia Medicare beneficiaries with MSP eligibility. Sixth, Equitable Relief under Section 1837(h) can waive the LEP when SSA or CMS error caused the delayed enrollment. Seventh, the BENES Act 2020 simplified GEP coverage to start the month after enrollment (effective January 2023), eliminating the six-month coverage delay that previously plagued GEP enrollees. Eighth, GeorgiaCares SHIP at 1-866-552-4464 provides free counseling on LEP avoidance, MSP application, and Equitable Relief preparation. :::
The Federal Framework: Section 1839(b) and Its Amendments
The Medicare Part B Late Enrollment Penalty was created in the original Social Security Amendments of 1965 (Public Law 89-97), the same legislation that created Medicare itself. Congress understood from the start that voluntary insurance programs face an adverse selection problem: if healthy seniors can delay enrollment until they need care, the risk pool tilts toward the sick and premiums spiral upward. The Part B LEP was designed to incentivize on-time enrollment by making delayed enrollment permanently more expensive. The statutory authority is Section 1839(b) of the Social Security Act, codified at 42 USC 1395r(b), with implementing regulations at 42 CFR 407.20, operational instructions in CMS Internet-Only Manual (IOM) Publication 100-04 Chapter 18, and SSA operational guidance in Program Operations Manual System (POMS) HI 00805.000 series.
The original Section 1839(b) language is nearly unchanged from 1965: the standard Part B premium is "increased by 10 percent of the monthly premium for each full 12 months" of delay beyond the Initial Enrollment Period. The Omnibus Budget Reconciliation Act of 1989 refined the LEP calculation and clarified the interaction with Special Enrollment Periods that had been created in earlier amendments. The Balanced Budget Act of 1997 (Public Law 105-33) made additional SEP refinements. The Medicare Modernization Act of 2003 (Public Law 108-173) expanded several SEPs to address gaps in the original framework. The Medicare Improvements for Patients and Providers Act of 2008 (MIPPA, Public Law 110-275) added the volcanic event SEP and made the Part D Low Income Subsidy (LIS) Special Enrollment Period continuous. The 21st Century Cures Act of 2016 made modifications to the COBRA SEP rules. Most recently, the Beneficiary Enrollment Notification and Eligibility Simplification (BENES) Act of 2020 (Public Law 116-260, Division CC, Title I), which took effect for enrollments occurring on or after January 1, 2023, eliminated the up-to-six-month coverage delay that previously plagued the General Enrollment Period, simplified the GEP coverage start date to the month after enrollment, and required CMS to send proactive notices to Social Security beneficiaries approaching age 65 about Medicare enrollment requirements.
The Section 1839(b)(3) exemption is the most important Georgia-specific provision in the entire LEP framework. Originally added as part of the Medicare Catastrophic Coverage Act of 1988 and refined in subsequent legislation, Section 1839(b)(3) provides that a beneficiary enrolled in the State Buy-In through a Medicare Savings Program (QMB, SLMB, or QI) is exempt from the LEP for months during which the Buy-In is active. This means that a low-income Georgia senior who racked up a substantial LEP through years of missed Part B enrollment can have that LEP effectively zeroed out by qualifying for a Medicare Savings Program through the Division of Family and Children Services (DFCS) and Georgia Department of Community Health (DCH). The LEP technically remains on the CMS record, but the beneficiary owes nothing while the State Buy-In is active, since Georgia pays the standard premium and the federal exemption removes the surcharge. This is the single most powerful tool in the LEP-relief toolkit for low-income Georgia families.
The Section 1837(h) Equitable Relief framework provides relief when the delayed enrollment was caused by error, misrepresentation, or inaction by a federal agency: typically SSA, CMS, the Office of Personnel Management (OPM) administering FEHB, or the Department of Defense administering TRICARE. Equitable Relief is discretionary, not automatic, and requires a written request supported by evidence: SSA records, contemporaneous notes, witness statements, or letters from the offending agency. SSA processes Equitable Relief requests under POMS HI 00805.270 with regional office concurrence. Approved requests can grant retroactive enrollment without LEP, prospective enrollment without LEP, or both. Equitable Relief is granted in thousands of cases per year nationally and is a critical safety valve for the LEP framework.
How the LEP Is Calculated: 10% Per 12 Months, Permanent
The Part B LEP calculation is mechanically simple but conceptually subtle. The formula: count the number of full 12-month periods between the end of the Initial Enrollment Period (or, in some cases, the end of a qualifying SEP) and the effective date of the actual Part B enrollment. Multiply that count by 10%. Apply that percentage to the standard Part B premium in effect each year (not the premium in effect at the time of delay). Add the resulting surcharge to the standard premium for each month for the rest of the beneficiary's life.
Partial 12-month periods do not count, only full 12-month periods. A beneficiary who enrolls 11 months late has no LEP. A beneficiary who enrolls 13 months late has a 10% LEP (one full 12-month period plus a partial period that does not count). A beneficiary who enrolls 25 months late has a 20% LEP (two full 12-month periods). A beneficiary who enrolls 60 months late has a 50% LEP (five full 12-month periods). A beneficiary who enrolls 120 months late has a 100% LEP, effectively doubling the standard premium for life.
The LEP recalculates each year as the standard Part B premium changes. The 2026 standard premium is $191.50 per month, up from $185 per month in 2025. A beneficiary with a 30% LEP in 2025 paid $185 + $55.50 = $240.50 per month. The same beneficiary in 2026 pays $191.50 + $57.45 = $248.95 per month. As the standard premium continues to rise with Medicare cost growth, the dollar value of the LEP rises in proportion. Many beneficiaries do not realize this: they assume the LEP is fixed at the dollar amount established when they first enrolled. It is not. The LEP is a percentage, and the percentage applies to whatever the current standard premium happens to be.
A few key wrinkles affect the calculation. First, the LEP is computed based on the standard premium even for beneficiaries who pay income-related premium adjustments (IRMAA) on top of the standard. A high-income beneficiary subject to IRMAA pays IRMAA plus the standard plus the LEP, with each component computed separately. Second, the LEP percentage is computed from the date the IEP ended, not from age 65 or the SSDI 25th-month date. The IEP runs seven months: three months before the 65th birthday month, the birth month itself, and three months after. A senior who turns 65 in June 2023 has an IEP running March through September 2023; if she enrolls in November 2025, the delay is from October 2023 through October 2025, which is 25 months, which produces a 20% LEP. Third, the LEP attaches to the beneficiary, not to the policy: switching plans (Original Medicare to Medicare Advantage, or vice versa) does not affect the LEP. Fourth, the LEP is owed even if the beneficiary qualifies for premium-free Part A through their work history; the LEP applies only to Part B and is on top of whatever Part A premium the beneficiary owes (zero for most).
Initial Enrollment Period (IEP): The Seven-Month Window
The Initial Enrollment Period under Section 1837(a) of the Social Security Act is the seven-month window during which a senior or person newly entitled to Social Security Disability Insurance (SSDI) can enroll in Medicare without penalty. For age-eligible beneficiaries (turning 65), the IEP runs from three months before the 65th birthday month through three months after the 65th birthday month. For example, a senior who turns 65 on August 15, 2026 has an IEP running May 1, 2026 through November 30, 2026. The IEP for SSDI-entitled beneficiaries runs around the 25th month of SSDI entitlement: three months before the 25th month, the 25th month itself, and three months after. SSDI beneficiaries are automatically enrolled in Part A and Part B at month 25, with the option to decline Part B if they have other coverage.
For age-eligible beneficiaries who are already collecting Social Security retirement or RRB benefits when they turn 65, enrollment in Part A and Part B is automatic. The beneficiary receives a Medicare card in the mail approximately three months before the 65th birthday with both Part A and Part B coverage starting on the first day of the birth month (or the prior month if the birthday falls on the first of the month). The beneficiary has the option to decline Part B by returning the card with the appropriate indication if they have other creditable coverage (typically a Group Health Plan from an active employer with 20+ employees). Most Georgians turning 65 who are already collecting Social Security do not need to take any action: the system enrolls them automatically.
For age-eligible beneficiaries who are not yet collecting Social Security (delayed retirement to age 67, 70, or later to maximize benefits), there is no automatic enrollment. The senior must actively enroll during the IEP through SSA, either online at ssa.gov/medicare, by phone at 1-800-772-1213, or in person at a local SSA office. This is the most common LEP trap in Georgia: a senior who delays Social Security to age 70 to maximize benefits assumes that Medicare also waits until age 70. It does not. Medicare and Social Security have separate enrollment frameworks, and a senior who delays Social Security must still enroll in Medicare during the IEP at age 65 or qualify for an SEP.
Enrollment during the IEP triggers coverage that starts on the first day of the birth month if the beneficiary enrolls during the three months before, the first of the following month if enrolling in the birth month or one month after, the first of the second month if enrolling two months after, and the first of the third month if enrolling three months after. Beneficiaries who enroll late in the IEP face up to a three-month gap between IEP enrollment and coverage start, which can be a real planning issue for those leaving employer coverage at age 65.
General Enrollment Period (GEP): January 1 Through March 31
Beneficiaries who miss the Initial Enrollment Period and do not qualify for a Special Enrollment Period must enroll in Part B during the General Enrollment Period, which runs every year from January 1 through March 31 under Section 1837(c) of the Social Security Act. Under the original GEP rules, coverage did not begin until July 1 of the same year, meaning a beneficiary enrolling on January 2 had to wait six months for coverage. The BENES Act 2020 changed this for enrollments on or after January 1, 2023: under the new rule, GEP coverage begins the first day of the month after enrollment. A beneficiary enrolling in January 2026 has coverage starting February 1, 2026. A beneficiary enrolling in March 2026 has coverage starting April 1, 2026.
The GEP is the safety valve for missed-IEP beneficiaries, but it does not waive the LEP. Every full 12-month period of delay from the end of the IEP through the start of GEP coverage adds 10% to the LEP. A senior who turned 65 in 2023, missed the IEP, and enrolls during the January 2026 GEP for February 2026 coverage has a delay of approximately 28 months, which produces a 20% LEP (two full 12-month periods).
The GEP is the wrong place for most Georgia seniors. If a senior has been working past age 65 with employer coverage from a large employer (20+ employees), the Working Aged GHP SEP described below is the correct enrollment vehicle, with no LEP. If the senior has lost employer coverage and is within 8 months of that loss, the GHP SEP applies, with no LEP. Only if the senior has no qualifying SEP and missed the IEP does the GEP become the right answer, and even then the Section 1839(b)(3) Buy-In exemption may eliminate the LEP for low-income beneficiaries.
The Working Aged Group Health Plan (GHP) Special Enrollment Period
The most important LEP-avoidance pathway is the Special Enrollment Period for beneficiaries who delayed Part B because they had coverage from a Group Health Plan based on current employment. The authority is Section 1838(g) of the Social Security Act and 42 CFR 407.20 through 407.26. The rule: a beneficiary who has coverage from a GHP based on current employment (the beneficiary's own or their spouse's) at age 65 can delay Part B without penalty while the active employment continues. When the employment ends or the GHP coverage based on active employment ends (whichever comes first), the beneficiary has an 8-month Special Enrollment Period during which to enroll in Part B without LEP. Coverage begins the first day of the month after enrollment, or up to three months later at the beneficiary's option.
The critical phrase in the statute is "current employment" or "active employment." Retiree coverage is not active employment coverage and does not qualify a beneficiary for the GHP SEP. A senior whose employer continues to offer retiree health benefits past age 65 still must enroll in Part B during the IEP at age 65, or face an LEP. This is among the most common LEP traps: the retiree assumes that any employer coverage delays Part B enrollment, but only active employment coverage does so.
The 20-employee rule matters here. Under the Medicare Secondary Payer rules (42 CFR Part 411, 42 USC 1395y), an employer with 20 or more employees must allow active employees age 65 and older to keep their GHP as primary, with Medicare as secondary. An employer with fewer than 20 employees is allowed (and effectively required) to make Medicare the primary payer for active employees 65+, meaning the GHP becomes secondary. Beneficiaries working for small employers (fewer than 20 employees) generally cannot delay Part B enrollment without LEP, because the small-employer GHP does not qualify for the Section 1838(g) SEP. There are exceptions and case-by-case analyses, but the general rule is: large employer (20+) GHP supports the GHP SEP; small employer (under 20) GHP does not.
The 8-month SEP window begins the first day of the month after active employment ends or after the GHP coverage based on active employment ends, whichever is earlier. A senior whose active employment ended on June 15, 2025 has an 8-month SEP from July 1, 2025 through February 28, 2026. Enrolling within that window prevents the LEP. Enrolling outside the window (in March 2026 or later) means the beneficiary must wait for the next GEP and pay the LEP.
The COBRA Trap: COBRA Does Not Extend the GHP SEP
COBRA coverage is the single most common cause of unintended LEPs in Georgia and nationally. The rule under 42 CFR 407.20 and confirmed in numerous CMS guidance documents is clear: COBRA coverage is not coverage based on current employment. It is continuation coverage available to former employees who have lost their active employment GHP. As a result, the 8-month Special Enrollment Period clock starts when the active employment ends, not when COBRA ends. A retiree who takes COBRA for the full 18 months after leaving employment has burned through the 8-month SEP about ten months before COBRA ends. By the time COBRA expires, the retiree faces a wait for the next GEP and an LEP.
There is no general fix for the COBRA trap. The fix is awareness: retirees with employer coverage approaching age 65 should plan for Part B enrollment to coincide with the end of active employment, regardless of whether COBRA is available. This is a frequent topic in GeorgiaCares SHIP counseling sessions and a recurring cause of Equitable Relief requests when the beneficiary received incorrect advice from a benefits administrator. If the benefits administrator gave specific written advice that COBRA would qualify for the GHP SEP, the beneficiary may have a viable Equitable Relief case under Section 1837(h), but the bar for relief is whether the misinformation came from a federal source (SSA, CMS) or an authorized agent. Misinformation from a private benefits administrator generally does not qualify for Equitable Relief, though SSA has discretion.
The International SEP, Volcanic Event SEP, and Other Specialized SEPs
Several specialized Special Enrollment Periods exist for less common circumstances. The International SEP is available to beneficiaries who lived outside the United States and were not eligible for premium-free Part A or had coverage equivalent to Medicare while abroad. The window opens upon return to the United States and runs for 6 months. Common scenarios: missionaries returning from overseas service, retired military living abroad on TRICARE, expatriates returning home.
The Volcanic Event SEP, added by MIPPA 2008, applies to beneficiaries who delayed enrollment because of a federally-declared disaster or emergency. The name reflects the original triggering event (Mount St. Helens-related delays), but the SEP has been used for hurricane-affected beneficiaries in Georgia and other states. The SEP window is 6 months from the end of the declared emergency period.
The Federal Employee Health Benefits (FEHB) SEP and TRICARE SEP cover federal employees and military beneficiaries who had FEHB or TRICARE coverage extending past age 65. FEHB enrollment continues for federal retirees and is treated similarly to private retiree coverage for LEP purposes, though specific rules apply. TRICARE for Life requires Part B enrollment to remain effective: a TRICARE beneficiary who fails to enroll in Part B at age 65 loses TRICARE coverage. The TRICARE SEP allows enrollment for those who experienced specific qualifying events.
The IDD SEP applies to beneficiaries with intellectual or developmental disabilities who can demonstrate that the disability caused the delayed enrollment. The Spouse Death SEP applies in limited circumstances. The newer SEPs added by the BENES Act 2020 (effective January 2023) cover additional exceptional circumstances, including formerly incarcerated individuals, terminated Medicaid eligibility, employer error situations, and "other exceptional circumstances" as determined by CMS.
Section 1839(b)(3) Buy-In Exemption: The Critical Georgia Pathway
The Section 1839(b)(3) Buy-In LEP exemption is the single most powerful tool for low-income Georgia beneficiaries facing an LEP. The statutory language at Section 1839(b)(3) of the Social Security Act provides that the LEP "shall not be increased" for months during which the State Buy-In is in effect. In plain English: while a Georgia beneficiary is enrolled in QMB, SLMB, or QI and the State Buy-In is paying the standard Part B premium, the LEP surcharge is not collected. The LEP technically remains on the CMS record, but the beneficiary owes nothing for the LEP during Buy-In months.
This is a critical pathway because it does not require the beneficiary to prove SSA error or qualify for Equitable Relief. The beneficiary need only qualify for one of the three Medicare Savings Programs that include Part B (QMB, SLMB, or QI) through DFCS, get the Buy-In activated, and the LEP is effectively eliminated for the duration of MSP enrollment. The 2026 Georgia MSP thresholds: QMB at 100% Federal Poverty Level (approximately $1,305 monthly income for single, $1,763 for couple), SLMB at 120% FPL ($1,566 single, $2,115 couple), QI at 135% FPL ($1,761 single, $2,378 couple). Asset limits are $9,660 single and $14,470 couple for QMB and SLMB; QI has no federal asset limit, and Georgia does not impose one. (QDWI also has a Buy-In, but it covers Part A only and does not affect the Part B LEP.)
The interaction between the LEP and MSP enrollment is sometimes counterintuitive. A Georgia senior with a $57.45 monthly LEP from a 3-year delay can apply for QMB through DFCS. If approved, the State Buy-In activates, Georgia pays the $191.50 standard Part B premium directly to CMS through the Coordination of Benefits Agreement (COBA) accretion process, and the LEP surcharge is exempted under Section 1839(b)(3). The beneficiary's monthly Part B cost drops from $248.95 (premium + LEP) to $0 (full Buy-In coverage with LEP exemption). If the beneficiary later loses MSP eligibility (income rises, assets exceed limits, life change), the State Buy-In ends and the beneficiary returns to paying the full premium plus the LEP. The LEP did not disappear during the Buy-In period; it was suppressed. It returns when the Buy-In ends.
A worked example illustrates the pathway: Mary, age 68, Atlanta. She missed her IEP in 2023 because she did not understand the rules. She enrolls in March 2026 GEP, with coverage starting April 2026. Her delay is approximately 30 months, producing a 20% LEP (two full 12-month periods). Her 2026 monthly cost without MSP would be $191.50 + $38.30 = $229.80. Mary applies for QMB through DFCS in March 2026. Her income is $1,200 per month (Social Security retirement) and her assets are $6,000. She qualifies for QMB. DFCS approves her application in April 2026 with retroactive coverage to March 2026 (the application month). The State Buy-In activates effective May 2026 (after the 4-6 week COBA accretion lag). For March and April 2026, Mary owes $229.80 per month, but Georgia Medicaid will reimburse her for these months once the Buy-In is fully retroactive (typically processed through DCH Medicaid Member Services). Starting May 2026, Mary owes $0 for Part B; Georgia pays the standard premium, and the Section 1839(b)(3) exemption removes the LEP surcharge. Mary's effective LEP is zero for as long as she remains QMB-enrolled.
Equitable Relief Under Section 1837(h)
Equitable Relief is the discretionary procedure by which CMS, acting through SSA, can waive the LEP and grant retroactive Part B enrollment when the beneficiary's failure to enroll on time was caused by misrepresentation, error, or inaction by a federal employee or authorized agent. The authority is Section 1837(h) of the Social Security Act, with operational instructions in POMS HI 00805.270. Common scenarios where Equitable Relief is approved: an SSA worker told the beneficiary at age 64 that he could "wait to enroll in Medicare until he stopped working" without explaining the small-employer rule; an SSA worker mailed an incorrect enrollment denial; CMS failed to process a timely enrollment request; the beneficiary received written confirmation of enrollment that did not actually take effect.
The Equitable Relief process is initiated by the beneficiary or their representative through a written request to the local SSA office or by phone at 1-800-772-1213. The request should describe the specific error or misinformation, include supporting documents (SSA notices, contemporaneous notes, witness statements), and request specific relief (retroactive enrollment, LEP waiver, or both). The local SSA office processes the request with regional office concurrence, applying POMS HI 00805.270 criteria. Approved relief can include retroactive enrollment to the date the beneficiary should have been enrolled, prospective enrollment without LEP, refund of LEP amounts already paid, and other corrective action.
Equitable Relief is granted in thousands of cases per year nationally, but the success rate depends heavily on documentation. Beneficiaries who can produce a contemporaneous SSA notice, a written response to a request, or other evidence of the error generally fare better than beneficiaries relying solely on recollection. The GeorgiaCares State Health Insurance Assistance Program (SHIP) at 1-866-552-4464 can help Georgia beneficiaries prepare Equitable Relief requests and is a free service. Atlanta Legal Aid Senior Citizens Law Project at 404-377-0701 and Georgia Legal Services Program at 1-800-498-9469 can provide legal representation for complex cases.
Equitable Relief is not available for delays caused solely by private parties (employer benefits administrators, insurance brokers, financial advisors) unless those parties were acting as authorized agents of a federal agency, which is rare. Beneficiaries who relied on private advice have limited federal recourse, though they may have state-law claims against the advisor. The Section 1839(b)(3) Buy-In exemption pathway often provides more reliable relief than Equitable Relief for low-income Georgia beneficiaries, and the two pathways are not mutually exclusive.
Comparison: Part B LEP vs. Part A LEP vs. Part D LEP
The Part B LEP is one of three Medicare LEPs, and each operates on different rules. The Part A LEP applies only to the small percentage of beneficiaries who must pay a Part A premium (those without enough Social Security work credits to receive premium-free Part A). It is 10% of the standard Part A premium for 12-month periods of delay, but unlike Part B, the Part A LEP is paid for only twice the period of delay (capped). A 2-year Part A delay produces a 10% LEP for 4 years, not for life. Most Georgia beneficiaries do not face a Part A LEP because they qualify for premium-free Part A through their work history or their spouse's.
The Part D LEP, established by the Medicare Modernization Act of 2003 (Public Law 108-173), applies to Part D prescription drug coverage. The calculation differs: 1% of the national base beneficiary premium (a benchmark that changes each year, $34.70 in 2026) for each full month of delay beyond the initial enrollment opportunity. A 24-month Part D delay produces a 24% Part D LEP, which translates to approximately $8.33 per month added to whatever Part D plan premium the beneficiary chooses. The Part D LEP is also permanent unless waived through Equitable Relief or the LIS continuous SEP (which functions similarly to the Part B Buy-In exemption for low-income beneficiaries).
The three LEPs are independent: a beneficiary can face Part A LEP, Part B LEP, and Part D LEP simultaneously if all three delays occurred. The Section 1839(b)(3) Buy-In exemption applies to the Part B LEP and is implemented through MSP enrollment. The LIS continuous SEP applies to the Part D LEP and is implemented through Extra Help (Low Income Subsidy) enrollment. Georgia beneficiaries who qualify for QMB automatically qualify for LIS, and the LIS automatically eliminates the Part D LEP for the duration of LIS enrollment. A beneficiary with QMB and LIS thus has both the Part B LEP and Part D LEP effectively suppressed, which is a substantial protection for low-income Georgians.
Medicare Advantage Effects on the LEP
Enrollment in a Medicare Advantage (Part C) plan does not affect the LEP. The Part B premium and any LEP surcharge are paid to CMS regardless of whether the beneficiary's Part B benefits are administered through Original Medicare or through a Medicare Advantage plan. Many Medicare Advantage plans offer a Part B premium giveback (also called Part B premium reduction), which provides a credit back to the beneficiary's Part B premium, but this giveback applies only to the standard premium and not to the LEP. A beneficiary with a $57.45 monthly LEP enrolled in a Medicare Advantage plan with a $25 Part B giveback still pays the full $57.45 LEP each month.
Switching from Original Medicare to Medicare Advantage or vice versa does not affect the LEP. The LEP is attached to the beneficiary's Part B enrollment, not to the choice of how Part B is delivered. A beneficiary who has been paying an LEP for 5 years and switches to Medicare Advantage continues to pay the LEP. A beneficiary who has been on Medicare Advantage and switches back to Original Medicare continues to pay the same LEP.
The interaction between Medicare Advantage and the Section 1839(b)(3) Buy-In exemption is straightforward: a beneficiary enrolled in QMB and a Medicare Advantage plan has the standard Part B premium paid by Georgia through the State Buy-In and the LEP surcharge exempted under Section 1839(b)(3). The Medicare Advantage plan delivers the Part B benefits but does not affect the underlying premium structure.
Worked Examples for Typical Georgia LEP Scenarios
Mary 68 Atlanta: missed IEP, qualifies for QMB, Buy-In exemption
Mary turned 65 on August 15, 2023 in Atlanta, Fulton County. She was collecting widow's benefits from Social Security at age 60 and assumed Medicare enrollment was automatic. The automatic enrollment is correct for beneficiaries collecting retirement or SSDI benefits at age 65, and Mary should have been auto-enrolled in Part A and Part B effective August 1, 2023. However, Mary had elected to receive Social Security benefits as paper checks rather than direct deposit, and her address change two months before her 65th birthday caused her Medicare welcome packet to go to her old address. The packet was returned to SSA, Mary never received the Medicare card, and the system processed it as if Mary had declined Part B. Mary did not realize she lacked Part B coverage until February 2026 when she went to the emergency room for a fall and the hospital billing department told her that her insurance card showed only Part A.
Mary's delay is approximately 30 months from August 2023 through February 2026, which translates to two full 12-month periods plus a partial period. Mary's LEP is 20% of the 2026 standard premium: $38.30 per month. Mary applies for Part B enrollment in March 2026 through the GEP. Her coverage starts April 1, 2026 under the BENES Act post-2023 rules. Her monthly Part B cost is $191.50 + $38.30 = $229.80.
Mary's income is $1,200 per month from Social Security widow's benefits, and her assets are $6,000 in checking and savings combined. She qualifies for QMB through DFCS. Her son helps her file the application through Georgia Gateway in March 2026. DFCS approves the application in April 2026 with retroactive coverage to March 2026. The State Buy-In activates effective May 2026 through the COBA accretion process. For March and April, Mary continues to pay $229.80 per month; she will be reimbursed by Georgia DCH for those months once retroactive Buy-In processing completes (typically 30-60 days). Starting May 2026, Mary pays $0 for Part B: Georgia pays the standard premium, and Section 1839(b)(3) exempts her from the LEP. Mary should also explore Equitable Relief for the SSA address-change error, which could grant retroactive Part B enrollment to August 2023 without LEP, providing additional protection if she ever loses QMB eligibility. GeorgiaCares can help her prepare the Equitable Relief request.
George 70 Savannah: COBRA SEP trap
George retired from his Savannah engineering firm in June 2021 at age 65. The firm had 150 employees, and George had been covered under the firm's GHP. At retirement, George elected COBRA coverage to continue his GHP for 18 months (through December 2022). He believed that the COBRA coverage would qualify him for the Special Enrollment Period for Part B when the COBRA ended, and that he could safely delay Part B enrollment without LEP through the COBRA period.
This was incorrect. COBRA is not coverage based on current employment under Section 1838(g). George's 8-month SEP started July 1, 2021 (the month after his active employment ended) and ran through February 28, 2022. George needed to enroll in Part B by February 28, 2022 to avoid LEP. He did not enroll until January 2023, after COBRA ended, expecting that the post-COBRA SEP would apply.
CMS denied the SEP claim because COBRA does not extend the GHP SEP. George's enrollment was processed through the January 2023 GEP, with coverage starting February 1, 2023 (under the new BENES Act rules effective January 2023). His delay from the end of his IEP (the IEP ended in November 2021, three months after his September 2021 birth month) through February 2023 is approximately 15 months, which produces a 10% LEP (one full 12-month period). George's 2026 monthly Part B cost is $191.50 + $19.15 = $210.65.
George's income of $4,200 per month from pension and Social Security exceeds Georgia MSP limits, so the Section 1839(b)(3) Buy-In exemption is not available to him. He explored Equitable Relief but did not have written documentation of any specific SSA misinformation; his belief about COBRA came from his firm's benefits administrator, not from SSA. SSA denied the Equitable Relief request. George pays the $19.15 monthly LEP for life. Over 20 years of retirement, his cumulative LEP cost is approximately $5,800 (using a flat 2026 dollar value; the actual figure rises as the standard premium rises). This was an avoidable LEP, and is the single most common LEP trap in Georgia.
Linda 73 Macon: active GHP SEP works perfectly
Linda continued working as a school administrator in Macon past age 65. She turned 65 in March 2018 and continued active employment through August 2025, when she retired. Throughout this period, she remained covered under the Bibb County School District GHP, which has well over 20 employees. Linda's daughter, a GeorgiaCares SHIP volunteer, had reviewed Linda's options at age 65 and confirmed that the GHP SEP applied and that Linda could safely delay Part B enrollment without LEP.
When Linda retired in August 2025, her 8-month SEP started September 1, 2025 and ran through April 30, 2026. Linda enrolled in Part B in October 2025 with coverage starting November 1, 2025, three months before her actual retirement-coverage gap (her active employment GHP continued through August 31, 2025, after which she switched to a Bibb County retiree health plan that wraps with Medicare). Her 2026 monthly Part B cost is $191.50 with no LEP. Linda is a textbook example of how the GHP SEP is supposed to work for Georgia retirees who continue working past age 65 with large-employer coverage.
A few details from Linda's case are worth highlighting. First, she documented the GHP SEP eligibility by completing Form CMS-L564 (Request for Employment Information), which her employer's HR office signed. Second, she enrolled through SSA directly, not through her retiree plan administrator. Third, she did not enroll in COBRA between her active employment and Medicare effective date; she went directly from active GHP to Medicare to retiree wrap coverage. Fourth, the daughter's SHIP training was invaluable in avoiding the COBRA trap that befell George in the previous example.
Robert 67 Augusta: Equitable Relief approved
Robert turned 65 in February 2022 in Augusta. He was not collecting Social Security at that time (he had planned to delay retirement to age 70 to maximize his benefit). In December 2021, Robert visited his local SSA office to ask about Medicare enrollment. The SSA worker told him that since he was still working with employer coverage and not yet collecting Social Security, he did not need to enroll in Medicare yet and that the system would notify him when he needed to enroll. This was incorrect: even beneficiaries not collecting Social Security must enroll in Part B during the IEP at age 65 if they want to avoid LEP, unless they qualify for a SEP, and Robert worked for a small employer (12 employees) so the GHP SEP did not apply to him.
Robert worked another two years before retiring in February 2024. After retirement, he applied for Social Security and Medicare in March 2024. SSA processed his Part B enrollment through the March 2024 GEP (which was still on the old rules at that time, since the BENES Act simplification did not apply to this scenario), with coverage starting July 1, 2024 (under the old rules) and an LEP of 20% (two full 12-month periods of delay from February 2022 to July 2024).
Robert's daughter, who works as a benefits consultant, immediately recognized the error and helped Robert prepare an Equitable Relief request. The request described the December 2021 SSA visit, named the worker who provided the incorrect advice, and included Robert's contemporaneous note from his appointment calendar that documented the visit and the substance of the advice received. The local SSA office in Augusta forwarded the request to the regional office for concurrence under POMS HI 00805.270.
Equitable Relief was approved in November 2024. The relief granted: Part B enrollment retroactive to February 2022 (Robert's IEP), LEP waived in full, and refund of the LEP amounts Robert had paid from July 2024 through November 2024 ($188 in total). Robert's 2026 monthly Part B cost is $191.50 with no LEP. The Equitable Relief outcome was substantially better than the Buy-In exemption would have been (Robert's pension exceeds MSP limits) and represents the ideal outcome when SSA error is well-documented.
Patricia 70 Columbus: International SEP
Patricia retired from a U.S. State Department position in 2018 at age 62 and moved to Italy where her daughter and grandchildren had relocated. She maintained Tricare coverage as a Federal employee retiree spouse and was eligible for premium-free Part A through her late husband's work history. She did not enroll in Part B at age 65 (March 2021) because she was living abroad with coverage that she believed was creditable for SEP purposes. She returned to Columbus, Georgia in October 2025 to live near her son after Italian healthcare access issues during her recovery from hip surgery.
Patricia's International SEP opened upon her return to the U.S. The 6-month SEP runs October 2025 through March 2026. She enrolled in Part B in November 2025 with coverage starting December 1, 2025. Her 2026 monthly Part B cost is $191.50 with no LEP. The International SEP is designed exactly for this scenario: beneficiaries who lived abroad and return to the U.S. should enroll within 6 months of return to avoid LEP.
A note on Tricare: Patricia's Tricare coverage actually requires Part B enrollment at age 65 to remain effective for Tricare for Life benefits. Patricia had been outside the U.S. and was using a different Tricare overseas variant during her time in Italy, which has different Part B requirements. Upon her return, Tricare for Life required her to enroll in Part B to maintain wrap coverage. The interaction between Tricare and Part B is complex and Tricare beneficiaries should consult with the Tricare Beneficiary Information Line at 1-877-874-2273 before delaying Part B enrollment at age 65.
Charles 75 Athens: permanent LEP from 5-year delay
Charles turned 65 in May 2018 in Athens. He had been self-employed as a freelance writer for decades with no employer coverage. He did not enroll in Part B because he did not understand the rules, was managing without coverage (he was healthy), and viewed Medicare as expensive. His IEP ended in August 2018 and he did not enroll for the next five years.
In June 2023, Charles was diagnosed with prostate cancer. He needed treatment and finally enrolled in Part B during the January 2024 GEP, with coverage starting February 2024 under the new BENES Act rules. His delay from August 2018 through February 2024 is approximately 65 months, which produces a 50% LEP (five full 12-month periods). His 2026 monthly Part B cost is $191.50 + $95.75 = $287.25.
Charles applied for QMB through DFCS in March 2024 with the help of GeorgiaCares. His income at that time was $1,150 per month from Social Security and his assets were $4,500. He was approved for QMB effective April 2024. The State Buy-In activated in May 2024, eliminating Charles's Part B premium and exempting the LEP. From May 2024 through the present, Charles has paid $0 for Part B and his cancer treatment has been covered. If Charles ever loses QMB eligibility (an unlikely scenario given his income trajectory and protected SSI/Social Security income), he would resume paying the $287.25 monthly cost (or whatever the equivalent figure is at that future date). The Section 1839(b)(3) exemption thus serves as effective LEP relief for Charles for the duration of his MSP eligibility, which is likely for life. Without the exemption, Charles would face $1,149 per year in LEP charges, or approximately $23,000 over 20 years.
Common Mistakes That Cause Avoidable LEPs
Georgia families lose tens of thousands of dollars in cumulative LEP charges each year because of preventable mistakes. The list below summarizes the most common errors observed by GeorgiaCares SHIP counselors, Atlanta Legal Aid attorneys, and Medicare Rights Center staff.
Assuming Medicare enrollment follows Social Security enrollment. They are separate. Delaying Social Security to age 70 does not delay the Medicare IEP. Enroll in Medicare at age 65 regardless of when you claim Social Security.
Assuming COBRA extends the GHP SEP. It does not. The 8-month SEP starts when active employment ends, not when COBRA ends. Plan Part B enrollment to coincide with the end of active employment, regardless of COBRA.
Assuming small-employer (under 20) GHP qualifies for the GHP SEP. It does not. Beneficiaries working for small employers must enroll in Part B during the IEP at age 65.
Assuming retiree coverage qualifies for the GHP SEP. It does not. Only coverage based on current employment qualifies. Retiree coverage is post-employment and triggers the IEP-or-LEP rule.
Forgetting to enroll in Medicare when delaying Social Security benefits. Common among professionals working past 65 who plan to claim Social Security at 70.
Missing the IEP because of an address change or lost mail. SSA notices and Medicare welcome packets go to the address on file. Update SSA records before approaching age 65.
Relying on benefits administrator advice instead of SSA. Private benefits administrators are not authorized SSA agents and incorrect advice from them generally does not qualify for Equitable Relief.
Failing to apply for MSP when eligible. The Section 1839(b)(3) exemption is one of the most powerful LEP relief mechanisms and is often missed because beneficiaries do not realize they qualify.
Confusing the Part B LEP with the Part D LEP. They are separate. A beneficiary can have both. MSP enrollment exempts the Part B LEP; LIS enrollment exempts the Part D LEP. Both are critical for low-income beneficiaries.
Assuming the LEP is fixed at the dollar amount established at enrollment. It is not. The LEP is a percentage and adjusts each year as the standard premium changes.
Failing to document SSA error in real time. Equitable Relief requests succeed or fail based on documentation. Take notes during SSA visits, retain notices, and request written confirmation of advice given.
Missing the 8-month GHP SEP window after retirement. The window is short. Enroll within 8 months of the end of active employment, not within 8 months of the end of any coverage.
Assuming Medicare Advantage enrollment eliminates the LEP. It does not. The LEP is on the underlying Part B enrollment, not on the choice of delivery.
Failing to claim retroactive MSP coverage. Georgia provides up to 3 months retroactive coverage for MSP applications, which can reduce LEP charges already paid before Buy-In activation.
Giving up after an LEP is assessed. The LEP can sometimes be reduced or eliminated through Equitable Relief, MSP enrollment, or specialized SEPs even years after the initial assessment. Consultation with GeorgiaCares or Medicare Rights Center is free and worthwhile.
Step by Step: How to Avoid or Eliminate a Georgia Part B LEP
The simplest LEP avoidance strategy: enroll in Part B during the IEP at age 65. If you are collecting Social Security or RRB benefits, enrollment is automatic and you simply confirm your election by retaining the Medicare card sent to you. If you are not collecting Social Security, actively enroll through SSA online (ssa.gov/medicare), by phone (1-800-772-1213), or in person at a local SSA office. Begin the enrollment process three months before your 65th birthday to ensure coverage starts on the first day of your birth month.
If you are working past 65 with active employment GHP from a large employer (20+), confirm with your HR office that the employer is in fact 20+ in size and that the GHP is based on active employment, not retiree coverage. Document this in writing (Form CMS-L564 signed by HR). At the end of your active employment, enroll in Part B within the 8-month SEP. Plan the transition to avoid relying on COBRA as a bridge; if COBRA is necessary, enroll in Part B during the SEP window even while still on COBRA.
If you missed the IEP and no SEP applies, your enrollment vehicle is the GEP (January 1 through March 31). Coverage starts the month after enrollment under post-2023 BENES Act rules. The LEP applies. Determine your LEP percentage by counting full 12-month periods between the end of your IEP and the GEP enrollment date. Multiply by 10%. Apply to the standard Part B premium.
If you face an LEP and have limited income and assets, apply for a Medicare Savings Program through DFCS via Georgia Gateway (gateway.ga.gov), by paper application from your local DFCS office, or with help from GeorgiaCares SHIP at 1-866-552-4464. Approval triggers the State Buy-In, which under Section 1839(b)(3) exempts you from LEP charges for the duration of MSP enrollment. The exemption applies to QMB, SLMB, and QI; QDWI exempts the Part A LEP only.
If the LEP resulted from SSA or CMS error, file an Equitable Relief request through your local SSA office. Include documentation of the error, contemporaneous notes, witness statements, and any written notices that reflect the misinformation. Request specific relief (retroactive enrollment, LEP waiver, or both). GeorgiaCares can help with preparation; for complex cases, contact Atlanta Legal Aid Senior Citizens Law Project (404-377-0701) or Georgia Legal Services Program (1-800-498-9469).
How Georgia DFCS, DCH, and Federal Agencies Coordinate on LEP Issues
The Georgia Department of Community Health (DCH) administers Medicaid and the Medicare Savings Programs. The Division of Family and Children Services (DFCS) accepts applications, determines eligibility, and codes the MSP into the Medicaid Management Information System (MMIS). The State Buy-In Agreement between DCH and CMS is the operational backbone of the Section 1839(b)(3) LEP exemption: when DCH MMIS shows an active QMB/SLMB/QI enrollment, the COBA daily file transmits an accretion to CMS, CMS updates the federal beneficiary record, SSA stops withholding the Part B premium from the Social Security check, and the LEP surcharge is suppressed for as long as the Buy-In remains active.
SSA administers Part B enrollment, processes Equitable Relief requests under Section 1837(h), and runs the Medicare enrollment system end-to-end through its field offices, teleservice centers, and online portal. SSA workers are the front line for LEP-related inquiries and the most common source of both correct guidance and (occasionally) incorrect guidance that triggers Equitable Relief. SSA does not determine MSP eligibility; that is DFCS's role. SSA does notify CMS of LEP determinations, retroactive enrollment decisions, and Equitable Relief outcomes through internal coordination.
CMS administers Medicare nationally, sets the Part B premium each year, processes the LEP calculations on the back end, runs the COBA exchange with state Medicaid agencies, and oversees the Medicare Advantage and Part D programs. CMS does not process individual Equitable Relief requests; that is SSA's role. CMS notifies beneficiaries of Part B enrollment changes through monthly notices and the annual Medicare and You handbook.
GeorgiaCares, the State Health Insurance Assistance Program (SHIP) for Georgia, is the free counseling resource for Medicare beneficiaries and is the single most useful starting point for any LEP issue. GeorgiaCares counselors can help beneficiaries understand their IEP and SEP options, prepare Equitable Relief requests, file MSP applications, and resolve disputes with SSA and CMS. The SHIP network is funded by the federal Administration for Community Living and is independent of insurance companies, providers, and plan sellers. GeorgiaCares is administered through the Georgia Division of Aging Services and reaches Georgians through Area Agencies on Aging, senior centers, and direct outreach.
Frequently Asked Questions
::: accordion
What is the Medicare Part B Late Enrollment Penalty?
The Part B LEP is a permanent monthly surcharge added to a beneficiary's Part B premium for each full 12-month period of delay beyond the Initial Enrollment Period. The penalty is 10% of the standard Part B premium for each 12-month period of delay, applied for life. Authority: Section 1839(b) of the Social Security Act and 42 CFR 407.20.
How much is the LEP in dollar terms in 2026?
The 2026 standard Part B premium is $191.50 per month. A 1-year LEP at 10% is $19.15 per month, or $229.80 per year. A 3-year LEP at 30% is $57.45 per month, or $689.40 per year. A 5-year LEP at 50% is $95.75 per month, or $1,149 per year. A 10-year LEP at 100% is $191.50 per month, doubling the standard premium.
Does the LEP go away if I switch to Medicare Advantage?
No. The LEP attaches to your Part B enrollment, not to your choice of delivery. Switching between Original Medicare and Medicare Advantage does not affect the LEP.
Does the LEP go away after a certain number of years?
No. The Part B LEP is permanent unless removed through Section 1839(b)(3) Buy-In exemption (for MSP enrollees), Section 1837(h) Equitable Relief, or another specific relief pathway. By contrast, the Part A LEP is capped at twice the period of delay.
When is the Initial Enrollment Period?
The IEP is a 7-month window that includes the 3 months before your 65th birthday month, the birth month itself, and 3 months after. For SSDI beneficiaries, the IEP is centered on the 25th month of SSDI entitlement.
When is the General Enrollment Period?
The GEP runs every year from January 1 through March 31. For enrollments after January 1, 2023 under the BENES Act, coverage starts the first day of the month after enrollment.
What is the Working Aged GHP Special Enrollment Period?
The GHP SEP under Section 1838(g) allows beneficiaries with coverage from a Group Health Plan based on current employment (their own or their spouse's) to delay Part B enrollment without LEP while active employment continues, then enroll within 8 months of when active employment ends. The employer must have 20 or more employees for the SEP to apply.
Does COBRA coverage qualify for the GHP SEP?
No. COBRA is continuation coverage, not active employment coverage. The 8-month GHP SEP clock starts when active employment ends, not when COBRA ends. This is the most common LEP trap in Georgia.
What is the Section 1839(b)(3) Buy-In exemption?
Section 1839(b)(3) of the Social Security Act provides that the LEP is not increased for months during which the State Buy-In is in effect. In practice, Georgia QMB, SLMB, and QI enrollees pay no LEP while their MSP enrollment is active. This is among the most powerful LEP relief mechanisms.
How do I apply for a Georgia Medicare Savings Program?
File an application through Georgia Gateway at gateway.ga.gov, by paper application at your local DFCS office, or with assistance from GeorgiaCares SHIP at 1-866-552-4464. DFCS processes the application and codes the MSP into MMIS, which then transmits the Buy-In accretion to CMS.
What is Equitable Relief?
Equitable Relief under Section 1837(h) is a discretionary process by which CMS, acting through SSA, can waive the LEP and grant retroactive Part B enrollment when the beneficiary's failure to enroll was caused by misrepresentation, error, or inaction by a federal employee or authorized agent. POMS HI 00805.270 governs.
How do I file for Equitable Relief?
Submit a written request through your local SSA office or by phone at 1-800-772-1213. Describe the specific error, include supporting documents (SSA notices, contemporaneous notes, witness statements), and request specific relief. GeorgiaCares SHIP can help; Atlanta Legal Aid and Georgia Legal Services can represent complex cases.
Does the LEP apply if I have employer retiree coverage?
Yes. Retiree coverage is not coverage based on current employment and does not qualify for the GHP SEP. Beneficiaries with employer retiree coverage at age 65 must enroll in Part B during the IEP or face an LEP.
What is the BENES Act 2020?
The Beneficiary Enrollment Notification and Eligibility Simplification Act of 2020 (Public Law 116-260) simplified Medicare enrollment for beneficiaries who use the GEP. For enrollments after January 1, 2023, GEP coverage starts the month after enrollment instead of being delayed until July 1, and CMS sends proactive notices to seniors approaching age 65.
How does the Part B LEP compare to the Part D LEP?
The Part B LEP is 10% per 12-month period of delay, applied to the standard Part B premium, for life. The Part D LEP is 1% per month of delay (effectively 12% per year), applied to the national base beneficiary premium ($34.70 in 2026), for life. Both LEPs can apply simultaneously and are computed independently.
Does Tricare for Life require Part B enrollment?
Yes. Tricare for Life requires Part B enrollment to remain effective for beneficiaries age 65 and older. Failure to enroll in Part B at age 65 causes loss of Tricare for Life coverage. Contact the Tricare Beneficiary Information Line at 1-877-874-2273 before delaying Part B.
What if I lived outside the U.S. and missed my IEP?
The International SEP allows enrollment within 6 months of return to the U.S. without LEP for beneficiaries who lived abroad and had qualifying foreign coverage.
Can I get retroactive MSP coverage in Georgia?
Yes. Georgia DFCS can grant up to 3 months of retroactive MSP coverage for QMB, SLMB, and QI, which can reduce LEP charges already paid. Apply with the retroactive months requested on the application.
Does the LEP apply to Part A?
The Part A LEP applies only to beneficiaries who must pay a Part A premium (those without 40 quarters of Social Security work credits). It is 10% of the standard Part A premium for 12-month periods of delay, but unlike Part B, the Part A LEP is paid only for twice the period of delay. Most Georgia beneficiaries qualify for premium-free Part A and do not face a Part A LEP.
What happens to the LEP if my income changes?
If your income drops and you become eligible for QMB, SLMB, or QI, the Section 1839(b)(3) Buy-In exemption suppresses the LEP for the duration of MSP enrollment. If your income rises and you lose MSP eligibility, the LEP resumes at the prevailing percentage. The LEP percentage itself never changes after initial assessment.
Does the LEP affect Medicare Advantage plan availability?
No. All Medicare Advantage plans are available to beneficiaries with LEPs. The LEP is paid to CMS on top of any plan premium.
Can I appeal my LEP?
You can request reconsideration of the LEP determination through SSA. If SSA upholds the LEP, you can pursue Equitable Relief under Section 1837(h), administrative review, and if exhausted, judicial review. The success rate depends heavily on documentation of any underlying SSA or CMS error.
Where can I get free help with LEP issues in Georgia?
GeorgiaCares SHIP at 1-866-552-4464 provides free Medicare counseling, including LEP analysis, MSP application help, and Equitable Relief preparation. Atlanta Legal Aid Senior Citizens Law Project (404-377-0701) and Georgia Legal Services Program (1-800-498-9469) provide legal representation for complex cases. Medicare Rights Center (1-800-333-4114) provides national counseling.
Does the LEP apply to those receiving SSDI?
The same LEP framework applies. SSDI beneficiaries have an IEP centered on the 25th month of SSDI entitlement and qualify for the same SEPs as age-eligible beneficiaries. The Section 1839(b)(3) Buy-In exemption applies if they qualify for QMB, SLMB, or QI.
What documentation do I need for an Equitable Relief request?
The strongest documentation includes contemporaneous notes (calendar entries, notebook records) from the date of any SSA visit, copies of any SSA notices that contained incorrect information, written statements from witnesses present at SSA visits, and any other contemporaneous evidence of misinformation. Recollection alone is generally insufficient.

Sources, Resources, and Where to Turn Next
The Medicare Part B Late Enrollment Penalty under Section 1839(b) of the Social Security Act and 42 CFR 407.20 is a permanent surcharge that adds 10% of the standard Part B premium for each full 12-month period of delay beyond the Initial Enrollment Period. The penalty was created in the original Social Security Amendments of 1965 (PL 89-97) and has been refined by OBRA 1989, BBA 1997, MMA 2003, MIPPA 2008, the 21st Century Cures Act 2016, and most recently the BENES Act 2020. The penalty is calculated as a percentage applied to the standard premium each year (not fixed at the time of delay), is permanent unless removed through specific relief pathways, and rises in dollar terms as the standard premium rises.
The most important relief pathways for Georgia families are: enrollment during the IEP at age 65 (the simplest prevention), the Working Aged GHP SEP (for beneficiaries with large-employer active GHP coverage), the Section 1839(b)(3) Buy-In exemption (for QMB, SLMB, and QI enrollees), and Section 1837(h) Equitable Relief (when SSA or CMS error caused the delay). The Section 1839(b)(3) exemption is especially powerful for low-income Georgians and is often missed because beneficiaries do not realize that MSP enrollment effectively wipes out the LEP for as long as MSP eligibility remains.
For Georgia families facing an LEP today, the action steps are: first, determine whether an exemption pathway applies by reviewing the SEPs, MSP eligibility, and Equitable Relief criteria; second, file an MSP application through DFCS if income and assets fit; third, prepare and file an Equitable Relief request if SSA or CMS error caused the delay; fourth, work with GeorgiaCares SHIP for free counseling and application assistance; fifth, document everything in real time to support any future relief request.
