Georgia Medicare Special Enrollment Periods (SEPs) Guide 2026

Last verified May 14, 2026

The standard Medicare enrollment windows — the Initial Enrollment Period (IEP), the General Enrollment Period (GEP), the Annual Enrollment Period (AEP), the Medicare Advantage Open Enrollment Period (MA OEP), and the Medigap Open Enrollment Period — are designed around a tidy and predictable life narrative: turn 65, enroll in Medicare, choose a plan during open enrollment, change it during the next open enrollment. But real life isn't tidy. Georgia Medicare beneficiaries lose their jobs, lose Medicaid eligibility at redetermination, move across counties or state lines, survive hurricanes, get released from incarceration, get misled by SSA representatives or employer HR departments, and otherwise encounter the kinds of life transitions that the standard enrollment calendar cannot accommodate.

Special Enrollment Periods (SEPs) are the federal statutory and regulatory framework that catches beneficiaries when life goes sideways. SEPs allow beneficiaries to make Medicare enrollment changes — adding Part B, switching Medicare Advantage plans, joining a Part D plan, switching back to Original Medicare, enrolling in a Medigap policy — outside the standard enrollment windows when qualifying life events occur.

The SEP framework is codified at:

• Section 1837(i) of the Social Security Act — Part A and Part B SEPs
• Section 1851(e)(4) of the Social Security Act — Medicare Advantage SEPs
• Section 1860D-1(b)(3) of the Social Security Act — Part D SEPs
• 42 CFR Part 407 Subpart B — Part B SEP regulations
• 42 CFR Part 422 Subpart B — MA SEP regulations
• 42 CFR Part 423 Subpart B — Part D SEP regulations

The framework was significantly reformed and expanded by Section 120 of the BENES Act of 2020 (Public Law 116-260, signed by President Donald J. Trump on December 27, 2020) and the implementing CMS Final Rule (CMS-4192-F) effective January 1, 2023. The Final Rule created five new "Exceptional Conditions" SEPs that significantly expand the safety net for beneficiaries who would otherwise be left out by life circumstances.

A subsequent CMS Final Rule (CMS-4205-F) effective January 1, 2025 converted the long-standing continuous monthly SEP for dual-eligible and Low-Income Subsidy (LIS) beneficiaries into a quarterly SEP — reducing churn while preserving the core protection.

For Georgia specifically, two recent events have made SEPs especially salient:

1. Post-PHE Medicaid Unwinding (2023-2024): Georgia lost approximately 545,000 Medicaid enrollees during the post-COVID-19 Public Health Emergency unwinding period. Many of these enrollees were Medicare-eligible duals who lost their secondary Medicaid coverage and triggered the new Loss of Medicaid Coverage SEP.

2. Hurricane Helene (September 2024): The FEMA disaster declaration FEMA-DR-4830-GA activated SEPs across 41 Georgia counties in late September 2024, allowing affected Medicare beneficiaries to make plan changes outside the standard windows.

This guide walks through every SEP available to Georgia Medicare beneficiaries — what triggers each SEP, how long it lasts, what coverage changes are allowed, what documentation is required, and how Georgia-specific operational realities affect the SEP experience.

The Two Types of SEPs

Medicare SEPs fall into two broad categories:

Part A and Part B SEPs

These SEPs allow beneficiaries to initially enroll in Part A or Part B (or both) outside the IEP and GEP. They are codified at Section 1837(i) SSA. The most common Part A/B SEP is the Working Aged SEP, which protects beneficiaries who delayed Part B enrollment because they had active employer coverage.

Medicare Advantage and Part D SEPs

These SEPs allow beneficiaries who are already enrolled in Medicare to switch between Medicare Advantage plans, between Part D plans, between MA and Original Medicare, or to join a plan for the first time outside the AEP and MA OEP. They are codified at Sections 1851(e)(4) and 1860D-1(b)(3) SSA.

This guide covers both categories — though Part A/B SEPs are the higher-stakes category because they affect access to basic Medicare coverage.

Part A and Part B SEPs

Working Aged SEP (Section 1837(i)(1) SSA)

The Working Aged SEP is the most-used Part A/B SEP. It allows beneficiaries who had active group health coverage through their own or their spouse's current employment to enroll in Part B (and Part A if not already enrolled) without late enrollment penalties.

Trigger: Loss of active employer group health coverage (or loss of active employment status).

Duration:

• Part B and premium Part A: 8 months starting the first month after the active employer coverage ends OR the active employment ends, whichever is earlier
• Part D: 63 days from loss of creditable prescription drug coverage

Coverage effective date: First day of the month following enrollment (or the beneficiary may choose to begin coverage retroactively up to 6 months prior, but not earlier than employment-based coverage ended).

Critical limitation: COBRA does NOT qualify as active employer coverage. The Working Aged SEP clock starts when active employment ends, not when COBRA ends. Beneficiaries who delay Medicare enrollment because they are on COBRA — believing COBRA extends their SEP — will find themselves outside the 8-month window when they finally try to enroll.

Eligible employer: For Medicare-as-secondary-payer rules to apply (which is what protects the SEP), the employer must have 20 or more employees. Beneficiaries with employer coverage from smaller employers must enroll in Part B at IEP because the smaller-employer coverage is secondary to Medicare, meaning Medicare is the primary payer regardless of employer coverage.

Disability SEP for SSDI-Aged Beneficiaries (Section 1837(i)(2) SSA)

For beneficiaries who became Medicare-entitled through SSDI but returned to work and had their SSDI benefits terminated, the Disability SEP allows re-enrollment if Medicare entitlement is later restored.

Loss of Other Creditable Coverage SEP

For beneficiaries who had non-employer "creditable coverage" (such as a state retiree health plan or a private retiree health plan) that meets Medicare's creditability standards, loss of that coverage can trigger a Part B and Part D SEP.

The Five Exceptional Conditions SEPs (CMS-4192-F, Effective January 1, 2023)

The CMS Final Rule CMS-4192-F implementing Section 120 of the BENES Act created five new "Exceptional Conditions" SEPs. These SEPs are codified at 42 CFR 407.23 and represent the most significant expansion of Medicare SEP protection in over a decade.

1. Termination of Medicaid Coverage SEP

Trigger: Loss of Medicaid eligibility (including loss of dual-eligible status).

Duration: 6 months from the date Medicaid coverage ends.

Coverage: Can enroll in Part B (and premium Part A) without late enrollment penalty.

Documentation: Medicaid termination notice from Georgia DCH/DFCS.

Georgia significance: This SEP was extraordinarily important during the post-PHE Medicaid unwinding in 2023-2024 when 545,000 Georgia Medicaid enrollees lost coverage. Many of these enrollees were Medicare-eligible duals (Qualified Medicare Beneficiaries — QMBs — or Specified Low-Income Medicare Beneficiaries — SLMBs) who lost their Medicare Savings Program coverage and now needed to enroll in Part B without penalty.

2. Misinformation by Employer or Group Health Plan SEP

Trigger: Beneficiary's failure to enroll in Part B at IEP was caused by misinformation provided by an employer or group health plan representative (such as HR telling the beneficiary they didn't need Part B because they had employer coverage when that coverage didn't actually qualify them for the Working Aged SEP).

Duration: 6 months from the date the misinformation was discovered.

Coverage: Can enroll in Part B without late enrollment penalty.

Documentation: Written documentation of the misinformation (correspondence, notes, statements from the employer).

Georgia significance: This SEP catches COBRA-misled beneficiaries — those who were told by employer HR or COBRA administrators that COBRA would extend their Medicare enrollment options. It also catches beneficiaries with small employers (under 20 employees) who were told they had a SEP when they didn't.

3. Misinformation by Federal Employee or Health Plan SEP

Trigger: Beneficiary's failure to enroll in Part B at IEP was caused by misinformation provided by a federal employee (SSA representative, CMS staff, Medicare.gov call center agent) or federal health plan (TRICARE, FEHB, VA).

Duration: 6 months from the date the misinformation was discovered.

Coverage: Can enroll in Part B without late enrollment penalty.

Documentation: Written documentation of the misinformation.

Georgia significance: SSA field offices in Georgia handle high volumes of Medicare enrollment inquiries, and occasional misinformation does occur. This SEP provides redress.

4. Formerly Incarcerated Individuals SEP

Trigger: Release from incarceration.

Duration: 12 months from the date of release.

Coverage: Can enroll in Part B without late enrollment penalty.

Documentation: Release paperwork from the correctional facility.

Georgia significance: Georgia operates 36 state prisons plus county jails and federal facilities. Approximately 2,000-3,000 incarcerated individuals are released annually in Georgia who are Medicare-eligible (typically age 65+ or SSDI beneficiaries whose disability persists during incarceration). This SEP provides a smooth pathway back to Medicare coverage.

5. Other Exceptional Conditions SEP

Trigger: Case-by-case CMS determination of an exceptional circumstance that prevented enrollment.

Duration: 6 months from the date the exceptional condition is resolved.

Coverage: Can enroll in Part B without late enrollment penalty.

Documentation: Case-specific documentation submitted to CMS.

Georgia significance: Catchall for unusual circumstances not fitting the other four exceptional conditions categories.

Medicare Advantage and Part D SEPs

For beneficiaries who are already enrolled in Medicare, the MA and Part D SEPs allow plan changes outside the AEP (October 15 - December 7) and MA OEP (January 1 - March 31).

Loss of Medicaid or Loss of LIS SEP (Quarterly, Per CMS-4205-F)

Trigger: Loss of Medicaid eligibility OR loss of Low-Income Subsidy (LIS / Extra Help) status.

Duration: One opportunity per quarter (Q1 January-March, Q2 April-June, Q3 July-September, Q4 October-December) plus one opportunity during AEP.

Coverage change allowed: One Part D plan change OR one MA plan change per quarter.

Effective date: First day of the month following enrollment.

Georgia significance: This SEP was historically a continuous monthly SEP — meaning dual-eligible beneficiaries could change Part D plans every month. CMS reformed this through Final Rule CMS-4205-F effective January 1, 2025, converting it to a quarterly SEP. The reform was driven by concerns about plan-switching churn (sometimes driven by aggressive marketing by brokers) and a perceived stability benefit for both beneficiaries and plans. Critics argue the reform reduces beneficiary protection for the most vulnerable population.

Geographic Move SEP

Trigger: Permanent move to a new address outside the current plan's service area.

Duration: 2 months before the move + the month of the move + 2 months after the move (total 5 months).

Coverage change allowed: Switch to a new MA or Part D plan in the new service area, or return to Original Medicare.

Documentation: Proof of new residence (utility bill, driver's license).

Georgia significance: Georgia's seasonal "snowbird" population — beneficiaries who spend winters in Florida — typically does NOT qualify for the Geographic Move SEP because they retain primary residence in Georgia. But permanent moves to Florida (or vice versa) do qualify, as do intra-state moves between Georgia plan service areas (some Georgia MA plans have limited service areas, such as Kaiser Permanente Georgia in metro Atlanta only).

Plan Termination or Contract Non-Renewal SEP

Trigger: Beneficiary's MA or Part D plan ends its contract with Medicare (terminates or non-renews).

Duration: 3 months before the plan termination through 2 months after, but practically the SEP runs from the official notice through 2 months after the plan ends.

Coverage change allowed: Switch to a new MA or Part D plan, or return to Original Medicare with Part D.

5-Star Plan Annual SEP

Trigger: A 5-star MA or Part D plan exists in the beneficiary's service area.

Duration: December 8 of each year through November 30 of the following year (a 358-day window).

Coverage change allowed: Switch to a 5-star plan once during the SEP window.

Georgia significance: 5-star plans are limited in Georgia — typically 1-3 plans per year achieve 5-star ratings in Georgia service areas. Kaiser Permanente has historically achieved 5-star ratings in metro Atlanta.

Disaster or Emergency SEP

Trigger: Federally-declared disaster or emergency that prevents the beneficiary from making timely enrollment decisions.

Duration: From the start of the FEMA incident period through the end of the FEMA incident period plus 4 months.

Coverage change allowed: Make enrollment changes that were prevented by the disaster.

Georgia significance: Hurricane season (June 1 - November 30) regularly generates FEMA disaster declarations in Georgia. Hurricane Helene (September 26-29, 2024) generated FEMA-DR-4830-GA, activating the Disaster SEP across 41 Georgia counties including Bibb, Burke, Candler, Columbia, Dodge, Emanuel, Evans, Glascock, Jefferson, Jenkins, Johnson, Laurens, Lincoln, McDuffie, Montgomery, Richmond, Screven, Tattnall, Telfair, Toombs, Treutlen, Warren, Washington, Wheeler, Wilkes, and others.

Misrepresentation by Plan SEP

Trigger: Beneficiary enrolled in a plan based on misrepresentation by the plan or its agent.

Duration: 90 days from the date of enrollment based on misrepresentation.

Coverage change allowed: Disenroll from the misrepresented plan and switch to another plan.

SEP for Beneficiaries with End-Stage Renal Disease (ESRD)

Background: Until January 1, 2021, ESRD beneficiaries were generally barred from enrolling in Medicare Advantage. The 21st Century Cures Act (Public Law 114-255, December 13, 2016) removed this restriction effective January 1, 2021, allowing ESRD beneficiaries to enroll in MA. The transition created various SEPs for affected beneficiaries.

Other SEPs

Various other SEPs exist for specific circumstances:

• SEP for individuals enrolled in a Special Needs Plan (SNP) who lose SNP eligibility
• SEP for individuals enrolled in PACE (Program of All-Inclusive Care for the Elderly)
• SEP for individuals released from a skilled nursing facility
• SEP for individuals affected by CMS sanctions against a plan

SEP Documentation Requirements

Most SEPs require documentation to establish eligibility. Common documentation includes:

GeorgiaCares SHIP counselors help beneficiaries assemble SEP documentation packages.

Equitable Relief Coordination

For beneficiaries whose enrollment errors don't fit cleanly into any SEP category — or who fall outside SEP timelines — Equitable Relief (SSA POMS GN 00204) provides a final safety net. Equitable Relief allows SSA to:

• Enroll the beneficiary in Part B outside the GEP
• Waive late enrollment penalties
• Backdate coverage to an earlier date

Equitable Relief is a discretionary administrative remedy. Success requires clear documentation of the misinformation or circumstance that caused the enrollment error. GeorgiaCares SHIP and Medicare Rights Center help file Equitable Relief requests.

Six Worked Examples for Georgia Beneficiaries

Example 1 — Fulton 66, Atlanta loss of employer coverage Working Aged SEP

Maria is a 66-year-old executive in Atlanta who has continued working past 65 with active employer coverage from her 2,500-employee marketing firm. She enrolled in Part A only at IEP (premium-free) and deferred Part B under the Working Aged SEP. She retires on March 31, 2026 with employer coverage ending the same day.

SEP triggered: Working Aged SEP, 8-month window starting April 1, 2026 (Part B) and 63-day window (Part D).

Maria's enrollment:

• Part B: enrolls April 15, 2026; coverage effective May 1, 2026
• Part D: enrolls April 15, 2026; coverage effective May 1, 2026
• Medigap: 6-month guaranteed-issue window opens May 1, 2026 (first day of month she's 65+ AND enrolled in Part B)
• Medicare Advantage: alternatively, could enroll in MA via ICEP-equivalent procedures

Outcome: Smooth Working Aged SEP enrollment, no penalties, full Medigap guaranteed-issue protection.

Example 2 — DeKalb 70, Medicaid loss SEP post-PHE unwinding

Thomas is a 70-year-old Atlanta resident who has been dually eligible for Medicare (since age 65) and Medicaid (QMB Plus) for 5 years. During Georgia's 2023-2024 Medicaid redetermination unwinding, Thomas's Medicaid case was administratively terminated in January 2024 because Georgia DFCS lost a redetermination form (the form had been mailed to an old address).

SEP triggered: Loss of Medicaid Coverage SEP (CMS-4192-F Exceptional Condition #1) — 6 months from January 1, 2024 = window runs through June 30, 2024.

Thomas's challenges:

• Suddenly responsible for $185.00/month Part B premium (previously paid by Medicaid as QMB)
• Lost Part D LIS automatic enrollment
• Faced cost-sharing on Medicare-covered services for the first time

Thomas's response:

• Worked with GeorgiaCares SHIP to file Medicaid reinstatement application
• Applied for Medicare Savings Program (MSP) standalone if Medicaid not reinstated
• Used Loss of Medicaid SEP to switch Part D plan to one with lower premium without LIS

Outcome: Medicaid reinstated April 2024 (3 months after termination); dual-eligible status restored; LIS reactivated. SEP not used because Medicaid was restored within the SEP window.

Example 3 — Cobb 68, geographic move to Florida service area SEP

Robert is a 68-year-old retiree in Marietta who has been enrolled in a Humana Medicare Advantage plan in metro Atlanta for 3 years. He decides to move permanently to Sarasota, Florida, in August 2026.

SEP triggered: Geographic Move SEP — window runs from June 2026 (2 months before move) through October 2026 (2 months after move).

Robert's enrollment:

• New plan selection: Humana MA plan available in Sarasota service area
• Effective date: September 1, 2026 (first day of month following enrollment in new plan)
• Original Medicare alternative: could return to Original Medicare + Part D + Medigap, but Medigap medical underwriting risk in Florida

Outcome: Smooth plan transition; no coverage gap.

Example 4 — Worth County 67, Hurricane Helene FEMA SEP

Janet is a 67-year-old retiree in Worth County who was about to enroll in a new Medicare Advantage plan during the AEP (October 15 - December 7, 2024) when Hurricane Helene struck on September 26-29, 2024. The storm caused widespread power outages, displaced her from her home, and prevented her from comparing plans on Medicare.gov.

SEP triggered: Disaster SEP — FEMA-DR-4830-GA covered Worth County. The SEP window ran from the start of the FEMA incident period (September 24, 2024) through the end of the incident period plus 4 months.

Janet's enrollment:

• Used Disaster SEP in January 2025 to enroll in a new MA plan after AEP had already ended
• Coverage effective February 1, 2025

Outcome: Disaster SEP preserved Janet's ability to make a timely plan change despite the hurricane disruption.

Example 5 — Bibb 65, Misinformation by Employer SEP after HR error

Carolyn is a 65-year-old retired Bibb County school administrator who enrolled in COBRA from her former employer after retiring. The school district HR department told her, incorrectly, that COBRA would extend her Working Aged SEP for Medicare. Based on this misinformation, Carolyn did NOT enroll in Medicare Part B at IEP.

Discovery of error: 18 months later, Carolyn applied for Medicare Part B via a Working Aged SEP and was told by SSA that COBRA does NOT qualify for the Working Aged SEP. She had missed her IEP, and her standard SEP options were exhausted.

SEP triggered: Misinformation by Employer or GHP SEP (CMS-4192-F Exceptional Condition #2) — 6 months from the date the misinformation was discovered.

Carolyn's documentation:

• Written emails from school district HR stating "your COBRA coverage extends your Medicare SEP"
• Notes from HR meetings where COBRA-Medicare coordination was discussed
• Statement from a current HR director acknowledging the prior advice was incorrect

Carolyn's enrollment:

• Filed Exceptional Conditions SEP request with SSA
• Approved within 60 days
• Enrolled in Part B without late enrollment penalty
• Medigap guaranteed-issue window opened upon Part B enrollment

Outcome: Misinformation by Employer SEP saved Carolyn from a $300+/month lifetime Part B penalty and preserved her Medigap protection.

Example 6 — Hall 69, released-from-incarceration SEP

Michael is a 69-year-old man who was incarcerated in a Georgia state prison for 8 years and released in April 2026. During incarceration, his Medicare Part B was suspended (per Section 1862(a)(3) SSA, Medicare does not pay for services in penal institutions). When Michael was released, he needed to re-enroll in Part B.

SEP triggered: Formerly Incarcerated Individuals SEP (CMS-4192-F Exceptional Condition #4) — 12 months from the date of release.

Michael's documentation:

• Release paperwork from Georgia Department of Corrections
• Proof of Medicare eligibility (Medicare card; SSA records)

Michael's enrollment:

• Re-enrolled in Part B via Formerly Incarcerated SEP in May 2026
• Coverage effective June 1, 2026
• Connected with GeorgiaCares SHIP for plan selection counseling
• Enrolled in standalone Part D plan via concurrent Part D SEP

Outcome: Smooth re-entry pathway to Medicare coverage; no late enrollment penalty.

Best Practices for Georgia Medicare SEP Navigation

1. Don't assume COBRA qualifies for the Working Aged SEP — it doesn't
2. Document every Medicare-related conversation with employer HR, SSA, or other officials
3. Keep Medicaid termination notices — they're SEP documentation
4. Update address with Medicare/SSA/your plan before moving (and immediately after)
5. Watch for FEMA disaster declarations during hurricane season
6. Use the Loss of Medicaid SEP if Medicaid coverage ends post-redetermination
7. Use the 5-Star Plan SEP if a 5-star plan becomes available
8. Coordinate Working Aged SEP timing with retirement date
9. Use GeorgiaCares SHIP for SEP eligibility verification
10. File Exceptional Conditions SEP for any misinformation-driven errors
11. Backdate coverage if possible to avoid coverage gaps
12. Don't wait until the last day of the SEP window
13. Coordinate Part D SEP with MA/Medigap SEPs
14. Use Equitable Relief as a final option if SEP doesn't apply

Common SEP Issues for Georgia Beneficiaries

1. Missed Working Aged SEP because of COBRA misconception
2. Missed Medicaid loss SEP because of failure to receive termination notice
3. Missed geographic move SEP because of seasonal vs permanent move confusion
4. Missed FEMA SEP because of unawareness of disaster declaration
5. Missed 5-star SEP because of plan rating timing
6. Failed Exceptional Conditions SEP request due to inadequate documentation
7. Quarterly dual-eligible SEP confusion post-CMS-4205-F (was continuous, now quarterly)
8. Wrong effective date assumption
9. Plan-broker driven SEP misuse (aggressive marketing using SEPs)
10. SEP timing conflicts with AEP / MA OEP
11. Documentation delays from Georgia DCH/DFCS
12. Multiple SEP eligibility confusion (which SEP to use)
13. SEP usage limits misunderstanding (some are one-time)
14. Medigap underwriting risk during SEP-driven plan transitions

Why SEPs Matter for Georgia Eldercare

Special Enrollment Periods are the federal safety net for Medicare beneficiaries whose lives don't fit neatly into the standard enrollment calendar. For Georgia's 1.5+ million Medicare beneficiaries, SEPs are activated by:

• Retirement from active employment (Working Aged SEP)
• Medicaid redetermination terminations (Loss of Medicaid SEP)
• Inter-state and intra-state moves (Geographic Move SEP)
• Hurricane season disasters (FEMA Disaster SEP)
• Plan terminations and contract non-renewals
• Misinformation from employers, SSA, or federal agencies (Exceptional Conditions SEPs)
• Release from incarceration (Formerly Incarcerated SEP)
• Dual-eligible and LIS status changes (Quarterly SEP per CMS-4205-F)

The SEP framework has been significantly expanded by the BENES Act of 2020 and CMS Final Rule CMS-4192-F (effective January 1, 2023), creating five new Exceptional Conditions SEPs that protect beneficiaries who would otherwise be left out by life circumstances. The CMS Final Rule CMS-4205-F (effective January 1, 2025) modernized the dual-eligible SEP to a quarterly cadence, balancing beneficiary protection with plan stability.

For Georgia, the two most consequential recent SEP activations are the post-PHE Medicaid unwinding (Georgia lost 545,000 Medicaid enrollees in 2023-2024) and Hurricane Helene FEMA-DR-4830-GA (September 2024, 41 counties). Both generated thousands of SEP-eligible scenarios that required GeorgiaCares SHIP counselors, Georgia DCH staff, Medicare Advantage plans, and the Social Security Administration to work in coordination to deliver beneficiary protections.

The SEP framework reflects a fundamental commitment: that Medicare enrollment rules must accommodate real life, not the other way around. For Georgia eldercare, this commitment is renewed every time a hurricane strikes, a Medicaid redetermination terminates coverage, an employer makes a coordination mistake, or a beneficiary is released from incarceration into a world where Medicare is part of the path back to health and stability.

Frequently Asked Questions

1. What is a Medicare Special Enrollment Period (SEP)?

A Medicare SEP is a federal mechanism that allows beneficiaries to make Medicare enrollment changes outside the standard enrollment windows (IEP, GEP, AEP, MA OEP, Medigap OEP) when qualifying life events occur. SEPs are codified at Section 1837(i) SSA for Part A and Part B, Section 1851(e)(4) SSA for Medicare Advantage, and Section 1860D-1(b)(3) SSA for Part D.

2. What is the Working Aged SEP?

The Working Aged SEP allows beneficiaries with active group health coverage through their own or their spouse's current employment (employer of 20+ employees) to enroll in Part B without late enrollment penalty. The SEP runs for 8 months after loss of active employer coverage.

3. Does COBRA qualify for the Working Aged SEP?

No. COBRA is terminated employer coverage continued at the former employee's expense and does NOT qualify as active employer coverage for SEP purposes. Beneficiaries on COBRA must enroll in Medicare during their IEP or face late enrollment penalties.

4. What is the BENES Act of 2020 and how did it change SEPs?

The BENES Act of 2020 (Public Law 116-260, signed December 27, 2020) reformed Medicare enrollment. Section 120 of the BENES Act directed CMS to create new "Exceptional Conditions" SEPs, which were implemented through CMS Final Rule CMS-4192-F effective January 1, 2023.

5. What are the five new Exceptional Conditions SEPs?

The five new Exceptional Conditions SEPs are: (1) Termination of Medicaid Coverage, (2) Misinformation by Employer or GHP, (3) Misinformation by Federal Employee or Health Plan, (4) Formerly Incarcerated Individuals, and (5) Other Exceptional Conditions.

6. What is the Loss of Medicaid Coverage SEP?

The Loss of Medicaid Coverage SEP allows beneficiaries who lost Medicaid eligibility to enroll in Medicare Part B without late enrollment penalty. The SEP lasts 6 months from the date Medicaid coverage ends.

7. How did Georgia's post-PHE Medicaid unwinding affect SEPs?

Georgia lost approximately 545,000 Medicaid enrollees during the 2023-2024 post-Public Health Emergency unwinding. Many of these enrollees were dual-eligibles who lost their Medicaid secondary coverage and used the new Loss of Medicaid SEP to maintain Medicare access.

8. What is the Misinformation by Employer SEP?

The Misinformation by Employer SEP allows beneficiaries who failed to enroll in Part B at IEP because of misinformation from their employer or group health plan to enroll without late enrollment penalty. The SEP lasts 6 months from the date the misinformation was discovered.

9. What is the Misinformation by Federal Employee SEP?

The Misinformation by Federal Employee SEP allows beneficiaries who failed to enroll in Part B at IEP because of misinformation from SSA, CMS, or other federal agency staff to enroll without penalty. The SEP lasts 6 months from discovery of the misinformation.

10. What is the Formerly Incarcerated Individuals SEP?

The Formerly Incarcerated Individuals SEP allows Medicare-eligible individuals released from incarceration to enroll in Part B without late enrollment penalty. The SEP lasts 12 months from the date of release.

11. What is the Quarterly Dual Eligible / LIS SEP?

The Quarterly Dual Eligible / LIS SEP is the modernized version (effective January 1, 2025, per CMS-4205-F) of the prior continuous monthly SEP for dual-eligibles and LIS recipients. Now it allows one Part D or MA plan change per quarter.

12. What is the Geographic Move SEP?

The Geographic Move SEP allows beneficiaries who permanently move to a new address outside their current plan's service area to switch plans. The SEP runs 2 months before the move through 2 months after.

13. What is the Plan Termination SEP?

The Plan Termination SEP applies when a beneficiary's MA or Part D plan ends its contract with Medicare. The SEP allows the beneficiary to enroll in a new plan or return to Original Medicare.

14. What is the 5-Star Plan SEP?

The 5-Star Plan SEP allows beneficiaries to switch to a 5-star MA or Part D plan once per year between December 8 and November 30 of the following year.

15. What is the Disaster or Emergency SEP?

The Disaster SEP applies during federally-declared disasters (FEMA declarations) and allows affected beneficiaries to make enrollment changes that were prevented by the disaster.

16. How did Hurricane Helene affect Georgia Medicare SEPs?

Hurricane Helene (September 2024) generated FEMA disaster declaration FEMA-DR-4830-GA, activating the Disaster SEP across 41 Georgia counties for affected Medicare beneficiaries.

17. What documentation is required for SEP enrollment?

Documentation varies by SEP. Common requirements include employer letters confirming end of coverage, Medicaid termination notices, FEMA declaration numbers, release paperwork from correctional facilities, and written documentation of misinformation.

18. What is the 8-month Working Aged SEP window?

The Working Aged SEP allows 8 months for Part B enrollment after active employer coverage ends. The 8-month window starts the first month after the active employer coverage ends OR active employment ends, whichever is earlier.

19. What is the 63-day Part D SEP for loss of creditable coverage?

When a beneficiary loses creditable prescription drug coverage (active employer drug coverage), they have 63 days to enroll in a Part D plan without late enrollment penalty.

20. Can I use multiple SEPs?

Yes, in theory. A single life event can trigger multiple SEPs (for example, retirement triggers Working Aged SEP for Part B AND Loss of Creditable Coverage SEP for Part D AND Medigap OEP for guaranteed-issue Medigap). However, plan-switching SEPs (like the quarterly dual SEP) have usage limits.

21. What is Equitable Relief?

Equitable Relief (SSA POMS GN 00204) is a discretionary administrative remedy that allows SSA to enroll beneficiaries outside the GEP, waive late enrollment penalties, or backdate coverage when the beneficiary made enrollment errors based on misinformation. It is the final safety net when no SEP applies.

22. Where can I get free help with my SEP in Georgia?

GeorgiaCares SHIP at 1-866-552-4464 provides free, unbiased SEP counseling. GeorgiaCares counselors help with eligibility verification, documentation, and enrollment paperwork.

23. Do SEPs apply to Medigap?

Generally, Medigap SEPs are limited to specific situations (loss of employer Medigap coverage, plan termination, move out of service area). Most Medigap enrollment outside the 6-month OEP is subject to medical underwriting. Georgia is not a guaranteed-issue state for Medigap outside the federal OEP.

24. How long do SEP-triggered enrollments take to become effective?

Typically, coverage becomes effective the first day of the month following enrollment. Some SEPs allow retroactive coverage backdated up to 6 months.

25. What if I miss my SEP window?

If you miss your SEP window, you may be able to use Equitable Relief if there was misinformation involved. Otherwise, you must wait for the next applicable enrollment window (GEP for Part B; AEP for MA/Part D).
