Georgia Medicare Part D: Drug Coverage and $2,100 Cap

In 2026, no one with Medicare Part D pays more than $2,100 out of pocket for covered drugs all year, the biggest change to the benefit since it began.1 Part D is Medicare's voluntary prescription drug coverage, established under the Medicare Modernization Act of 2003 and codified at Section 1860D-1 through Section 1860D-43 of the Social Security Act (42 USC 1395w-101 et seq.). This guide is written for Georgia families choosing and using a plan: how the drug benefit works here in 2026, what standalone Prescription Drug Plans (PDPs) and Medicare Advantage Prescription Drug plans (MA-PDs) cost across Georgia's counties, how the Low Income Subsidy and the Medicare Prescription Payment Plan help, and where to get free local help. For the federal mechanics that apply in every state, see How Medicare Part D Works in 2026.

The Inflation Reduction Act of 2022 (PL 117-169) did it, and 2026 is the first full year Georgia families feel all of it. The IRA replaced the old four-phase design (including the coverage-gap "donut hole") with a three-phase benefit capped at $2,100 in out-of-pocket drug costs, up from $2,000 in 2025.1 It also created the Medicare Prescription Payment Plan (M3P), which lets you spread that capped amount across the calendar year; capped covered insulin at $35 for a one-month supply, with no deductible;2 made ACIP-recommended adult vaccines $0; expanded the Low Income Subsidy (Extra Help) to 150 percent of the federal poverty level;3 and started Medicare drug-price negotiation for the first 10 selected drugs effective January 2026.

For a Georgia senior on a high-cost specialty drug, that changes everything: someone who once faced many thousands of dollars a year in out-of-pocket costs now pays no more than $2,100, and can spread even that across 12 months through M3P.1 A Georgia retiree with diabetes pays no more than $35 a month for each covered insulin.2

The Federal Framework: Section 1860D of the Social Security Act

Part D is federal: Section 1860D of the Social Security Act, effective January 2006, with implementing regulations at 42 CFR Part 423. The benefit design, enrollment periods, penalties, and appeals below are the same in Georgia as in every other state; what varies here is which plans and carriers are available and where you get local help. For the full federal history, see How Medicare Part D Works in 2026.

The 2026 Medicare Part D Benefit Design in Georgia

The 2026 standard benefit runs in three phases, with the old coverage gap eliminated. You pay 100 percent of drug costs up to the annual deductible (up to $615 in 2026; plans can charge less), then 25 percent coinsurance or your plan's tier copays, then $0 for all covered drugs for the rest of the year once your out-of-pocket spending reaches the $2,100 cap.4,1 Most Georgia plans use copay tiers rather than flat 25 percent coinsurance, so the same drug can cost very different amounts across plans.

What counts toward the $2,100 cap and what does not, plus the phase mechanics in full, live in our Georgia Part D out-of-pocket cap guide and the national How Medicare Part D Works hub.1 Brand-name drugs also carry a manufacturer discount in the initial and catastrophic phases, under the program that replaced the old coverage-gap discount in January 2025, though in most cases that discount lowers your plan's liability rather than your own cost-sharing; which drugs it applies to and what each phase's rate is are in our Georgia Medicare Manufacturer Discount Program guide.7

The Medicare Prescription Payment Plan (M3P)

The Medicare Prescription Payment Plan, effective January 2025 under Section 11202 of IRA 2022, lets you pay $0 at the pharmacy and have your plan invoice your accumulated out-of-pocket costs in monthly installments instead; it does not lower total drug costs and there is no fee, it only smooths the timing, and every Part D and MA-PD plan must offer it.8 The trade-off: if you miss a monthly invoice you are removed and go back to paying at the pharmacy, so opt in only if you can keep up with the payments. How the monthly amount is calculated and how to opt in are in our Georgia Medicare Prescription Payment Plan (M3P) walkthrough.

Georgia Medicare Part D Plan Types: PDP vs MA-PD

Standalone Prescription Drug Plans (PDPs)

PDPs are designed for beneficiaries enrolled in Original Medicare. Key features:

• Combined with Original Medicare (and optionally Medigap)
• Premiums vary by plan; compare your ZIP and your drug list on the Medicare Plan Finder
• Available state-wide across all 159 Georgia counties

Medicare Advantage Prescription Drug Plans (MA-PDs)

Most MA plans include Part D coverage. Features:

• Combined Medicare Part A + Part B + Part D in one plan
• Premium often $0 (built into the MA plan); every Medicare-eligible Georgian has access to at least one $0-premium MA plan for 20269
• Cannot be combined with a standalone PDP
• How many plans you can actually choose from is in the Georgia carrier landscape below

Plans Without Part D

Some beneficiaries do not enroll in Part D because they have other creditable coverage (see Medicare's definition of creditable drug coverage):

• Employer or retiree health plan with creditable drug coverage
• VA prescription coverage
• TRICARE prescription coverage
• Some Indian Health Service coverage

Enrollment Periods

Initial Enrollment Period (IEP)

The Part D IEP aligns with the Medicare IEP, a 7-month window beginning 3 months before the month of 65th birthday (or month of Medicare eligibility) and ending 3 months after. Beneficiaries should enroll in Part D during their IEP to avoid the late enrollment penalty.10

Annual Election Period (AEP)

The Annual Election Period runs October 15 through December 7 each year.10 During AEP, beneficiaries can:

• Enroll in Part D for the first time (subject to LEP)
• Switch from one PDP to another
• Switch from PDP to MA-PD or vice versa
• Drop Part D coverage

AEP elections are effective January 1 of the following year. Beneficiaries already in a Medicare Advantage plan also get the Medicare Advantage Open Enrollment Period (MA-OEP), January 1 through March 31, to switch MA plans or return to Original Medicare with a PDP.10

Special Enrollment Periods (SEPs)

Several SEPs allow Part D enrollment changes outside AEP:

• Move outside service area: 2-month SEP
• Lose creditable coverage involuntarily: 2-month SEP
• Qualify for LIS Extra Help: SEP for plan changes
• Qualify for QMB/SLMB/QI: SEP
• Plan termination by CMS: 3-month SEP
• 5-star plan SEP: December 8 through November 30 each year for switching to a 5-star plan
• Disaster declaration SEP: for federal, state, or local disasters
• Exceptional Conditions SEP: under 42 CFR 407.23 (2023 regulation)

2024 LIS Quarterly SEP

Effective January 2024, CMS changed the SEP for LIS-eligible beneficiaries from monthly to quarterly for most categories. Full-benefit dual-eligibles retain monthly SEPs under most circumstances. The change was designed to reduce plan switching driven by broker incentives rather than beneficiary needs.

Late Enrollment Penalty (LEP)

The Part D late enrollment penalty under Section 1860D-13(b) is a permanent surcharge for those who delayed enrollment without creditable drug coverage: 1 percent of the national base beneficiary premium ($38.99 in 2026) for each uncovered month, rounded to the nearest $0.10 and added to your plan premium for as long as you have Medicare drug coverage. It follows you even when you change plans.5

Employer or union drug coverage actuarially equivalent to Part D, VA coverage, and TRICARE generally count as creditable; keep the documentation in case a penalty is applied incorrectly, and request reconsideration through your plan (with IRE appeal) if it is. What counts as creditable coverage and the full penalty-dispute walkthrough are in our Georgia Medicare creditable coverage guide.

Low Income Subsidy (Extra Help)

The Low Income Subsidy (LIS), also called Extra Help, is a federal subsidy for low-income Medicare beneficiaries that pays for Part D premiums, deductibles, and most cost-sharing.

LIS Eligibility (2026)

Income limit: below 150 percent of the federal poverty level, in the 48 contiguous states and DC (Alaska and Hawaii higher). The IRA 2022 expansion effective January 2024 eliminated the partial-subsidy tier, so everyone who qualifies gets the full subsidy:

• about $23,940/year individual (2026)
• about $32,460/year for a married couple (2026)3

Resource (asset) limits for full Extra Help (CY2026):

• $16,590 individual
• $33,100 married couple (both rise to $18,090 / $36,100 if you tell SSA you expect to use some resources for burial expenses)3

Some beneficiaries are automatically enrolled in LIS:

• Full Medicaid dual-eligibles
• QMB, SLMB, QI enrollees (Medicare Savings Programs)
• Supplemental Security Income (SSI) recipients

Full LIS Benefits (2026)

• $0 plan premium (for benchmark plans)
• $0 annual deductible
• Copays of no more than $5.10 per generic and $12.65 per brand-name covered drug
• $0 once out-of-pocket drug costs reach the $2,100 catastrophic threshold3

Applying for LIS

Apply through Social Security Administration:

• Online at ssa.gov/medicare/prescriptionhelp
• Form SSA-1020 paper application
• Phone 1-800-772-121311
• In person at Social Security office

LIS applications are also processed automatically when beneficiaries qualify for QMB, SLMB, or QI through Georgia Medicaid.

Formularies and Drug Coverage

Formulary Definition

A formulary is the list of drugs a Part D plan covers. Each plan has its own formulary, subject to CMS approval. Formularies must:

• Cover at least 2 drugs in each therapeutic category
• Cover all drugs in 6 protected classes
• Use therapeutic alternatives appropriately
• Comply with USP MMG (Medicare Model Guidelines)

The Six Protected Classes

Part D plans must cover "all or substantially all" drugs in these six classes, a protection codified at 42 CFR 423.120(b)(2)(v) and Section 1860D-4(b)(3)(G) of the Social Security Act:

1. Antidepressants
2. Antipsychotics
3. Anticonvulsants
4. Antiretrovirals (HIV/AIDS treatments)
5. Immunosuppressants (transplant medications)
6. Antineoplastics (cancer treatments)

This protection ensures access to critical medications without delays from restricted formulary access. Plans may apply prior authorization or step therapy in these classes only to new starts (never to antiretrovirals).12

Tier Structure

Most Part D plans use a 5-tier formulary structure:

• Tier 1 (preferred generic): lowest cost-sharing, generic drugs the plan prefers
• Tier 2 (generic): generic drugs not on tier 1
• Tier 3 (preferred brand): brand-name drugs the plan prefers
• Tier 4 (non-preferred drug): higher-cost brand or generic drugs
• Tier 5 (specialty): very high-cost drugs on the plan's specialty tier

Formulary Restrictions

Plans can apply utilization management to formulary drugs:

• Prior authorization (PA): plan approval required before covering
• Step therapy: must try preferred drug first before covering specific drug
• Quantity limits: restriction on amount dispensed per fill
• Mail-order required: some maintenance medications must be filled by mail-order

Appeals and Exceptions Process

Part D has a five-level appeals process under 42 CFR 423.560-423.638, and each level has a deadline:13

1. Coverage determination. Your request to the plan to cover a drug. The plan must respond within 72 hours for a standard request, or 24 hours expedited when your health is at risk.
2. Redetermination. If the coverage determination is unfavorable, request redetermination by the plan within 60 days. The plan must respond within 7 days, or 72 hours expedited.
3. Independent Review Entity (IRE). If redetermination is unfavorable, Maximus, the CMS-contracted IRE, reviews within 7 days, or 72 hours expedited.
4. Administrative Law Judge (ALJ) hearing. At the Office of Medicare Hearings and Appeals, typically by telephone or video, with a decision in 90 days. For calendar year 2026 the amount in controversy must be at least $200.13
5. Medicare Appeals Council, then federal court. Judicial review in federal district court for calendar year 2026 requires the amount in controversy to be at least $1,960.13

Tiering Exception

Beneficiaries can request that a non-preferred drug be covered at preferred tier cost-sharing. Must demonstrate:

• Other formulary drugs are not as effective
• Other formulary drugs have caused adverse effects
• Medical necessity for the requested drug at preferred tier

Formulary Exception

Beneficiaries can request coverage of a drug not on the formulary at all. Must demonstrate:

• All formulary alternatives have been ineffective or are contraindicated
• Medical necessity for the specific drug

Quantity Limit Exception

Beneficiaries can request higher quantity than the plan's quantity limit. Must demonstrate medical necessity for the higher dose or quantity.

Pharmacy Networks

Most Georgia plans have a network with two cost tiers: preferred pharmacies (often national chains like CVS, Walgreens, or Walmart, plus regional chains) charge the lowest copays, while standard in-network pharmacies charge more. Out-of-network pharmacies generally are not covered except in emergencies, so verify your pharmacy is in the plan's network before you enroll. For maintenance medications, mail-order usually offers 90-day supplies at the lowest cost-sharing.

Medicare Drug Price Negotiation

Under the Inflation Reduction Act, Medicare negotiated prices for the first 10 drugs (Eliquis, Jardiance, Xarelto, Januvia, Farxiga, Entresto, Enbrel, Imbruvica, Stelara, and Fiasp/NovoLog) that take effect January 2026; manufacturers cannot charge more than the Maximum Fair Price, all Part D plans must offer the drug at that price, and more drugs are added each year. If you take one of these drugs, your plan's cost-sharing for it should fall in 2026. For the full Georgia breakdown, see Georgia Medicare Drug Price Negotiation.

Georgia Part D Carrier Landscape

Major PDP Carriers in Georgia (2026)

• Humana : multiple PDPs, strong Georgia presence
• WellCare (Centene) : value-focused PDPs
• AARP UnitedHealthcare : comprehensive PDPs
• SilverScript (Aetna/CVS) : large national presence
• Cigna : moderate Georgia presence
• Anthem BCBS of Georgia : regional carrier
• Mutual of Omaha Rx : focused on lower-premium plans
• Express Scripts : PBM-affiliated plans

Plan Variety

Georgia is a high-Medicare-Advantage state. As of March 2026, CMS counted 2,019,345 people with Medicare in Georgia: 1,132,430 in Medicare Advantage and other health plans, and 886,915 in Original Medicare. More than half of Georgia's beneficiaries are covered through a plan rather than Original Medicare. CMS reports 180 Medicare Advantage plans available statewide for 2026, up from 178 in 2025, and the average monthly MA premium fell from $13.76 in 2025 to $6.74 in 2026. Read that 180 as a statewide total, not as your own choice list: KFF's analysis of the CMS landscape files, which counts only plans open to general enrollment, finds the average Georgia beneficiary chooses among 47 plans from an average of 8 insurers. Every Medicare-eligible Georgian has access to at least one $0-premium MA plan for 2026.9

What Plans Cost in Georgia

Standalone PDP premiums vary widely by plan, and a low-premium plan can cost more overall once its deductible and copays are counted. Do not choose on premium alone. Extra Help enrollees pay $0 premium for benchmark plans.3 The only reliable way to compare total annual cost for your own drug list is the Medicare Plan Finder, which ranks plans by estimated yearly cost for your ZIP code and medications.

Worked Examples

The plan names, premiums, and copays in the following examples are hypothetical and for illustration only; confirm current figures on the Medicare Plan Finder before deciding. The federal figures each example turns on (the out-of-pocket cap, the standard deductible, the base premium, and the Extra Help copay maximums) are cited in the sections above.

Robert 70 Savannah: Late Enrollment Penalty

Robert enrolled in Original Medicare at age 65 in 2020 but did NOT enroll in Part D. He paid out of pocket for occasional medications, assuming he could enroll later "if needed."

Five years later (60 months), in 2025, he is prescribed a statin and applies during AEP for January 2026 coverage.

Plan calculates LEP:5

• 60 months delay x 1% = 60% LEP
• 2026 national base beneficiary premium: $38.99
• Penalty: that percentage of the base premium, rounded to the nearest $0.10
• LEP added to plan premium permanently

Medicare's own worked example: a 14-month delay is a 14% penalty, $38.99 x 0.14 = $5.46, rounded to $5.50 a month. Robert's 60% penalty rides on his plan premium for life.5

Linda 67 Macon: High-Cost Drug + $2,100 Cap

Linda is diagnosed with rheumatoid arthritis. Her rheumatologist prescribes Enbrel (etanercept), a high-cost specialty biologic.1

Before the IRA 2025 reform, Linda would have faced:1

• $615 deductible
• 25% coinsurance in initial coverage = $2,100+/month
• Coverage gap with manufacturer discounts
• 5% catastrophic phase = $450/month even after large initial costs
• Annual total: $7,000-$10,000

Under IRA 2025 reform, Linda's experience is dramatically different:1

• January 2026: Enbrel filled, pays $615 deductible + 25% coinsurance until reaching $2,100 OOP
• Reaches $2,100 OOP by mid-to-late January
• February through December: $0 for Enbrel
• Annual total: $2,100 (vs. $7,000-$10,000 before)

Note: Enbrel is one of the first 10 drugs subject to Medicare price negotiation effective January 2026. The Maximum Fair Price will reduce overall plan costs and may further reduce Linda's exposure.

Patricia 65 Columbus: LIS Extra Help

Patricia's only income is $1,400/month from Social Security retirement ($16,800/year). The 2026 federal poverty level is $15,960 for a single person. Patricia's income is 105 percent FPL, below the 150 percent threshold for full LIS.14

After the IRA 2022 expansion effective 2024, Patricia qualifies for the full subsidy described above.3 DCH automatically coordinates Patricia's QMB enrollment with SSA LIS processing.

Patricia chooses Humana Premier Rx benchmark plan. Her annual Part D cost:3

• Premium: $0
• Deductible: $0
• Estimated copays for her 4 medications: $35/year
• Total: $35

Without LIS, Patricia would have paid several hundred dollars a year more for the same coverage.3

Henry 75 Athens: MA-PD to PDP Switch

Henry has been enrolled in Humana MA-PD for 3 years with a $0 premium. His new prescription for a specialty medication is not on the Humana formulary, requiring step therapy and prior authorization.9

Henry compares standalone PDPs available with Original Medicare:9

• WellCare Wellness Rx: $0 premium, but doesn't cover his drug
• Humana Premier Rx: $84/month premium, covers his drug
• AARP UHC Preferred Rx: $44/month premium, covers his drug, lower copays

Henry decides to switch to Original Medicare + AARP UHC Preferred Rx PDP + Medigap Plan G during AEP 2025.

Switch effective January 1, 2026:

• AARP UHC PDP: $44/month
• Plan G Medigap: $165/month (assuming standard rate)
• Part B premium: $202.90/month15
• Total: $411.90/month

Compared to his MA-PD ($202.90/month Part B + $0 plan), Henry pays approximately $200 more per month but gains:15

• Full medication coverage for his specialty drug
• Any Medicare-accepting provider nationwide
• No prior authorization for most services

Common Part D Mistakes Georgia Families Make

1. Not verifying your drugs are on the formulary before enrolling. A drug covered by one plan may not be covered by another; check your own drug list on the Plan Finder.

2. Missing the AEP (October 15 to December 7). Outside AEP, switching generally requires a Special Enrollment Period.

3. Not understanding you cannot hold both a PDP and an MA-PD. Enrolling in a standalone PDP automatically drops your MA-PD.

4. Not exploring Extra Help when income-eligible. The 2024 expansion to 150 percent FPL means many more Georgia seniors now qualify.3

5. Not appealing a formulary denial. Tiering, formulary, and quantity-limit exceptions are often granted with a prescriber's supporting statement.

6. Not checking Star Ratings. Higher-rated plans tend to have better service and fewer member complaints; GeorgiaCares SHIP can help you compare.
