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 prescription drug coverage, sold through private plans. This guide is for Georgia families choosing and using a plan: what standalone Prescription Drug Plans (PDPs) and Medicare Advantage Prescription Drug plans (MA-PDs) cost here, 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 under Part D, with no deductible;3 expanded the Low Income Subsidy (Extra Help) to 150 percent of the federal poverty level;4 and started Medicare drug-price negotiation, with negotiated prices for the first 10 selected drugs effective January 1, 2026.5

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 the calendar year through M3P.1

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

Part D is federal: its rules come from section 1860D of the Social Security Act and CMS 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.

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.6,1 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 the phase mechanics in full, are in our Georgia Part D out-of-pocket cap guide and the national How Medicare Part D Works hub.1 Drugs approved under a new drug application or licensed as biologics (biosimilars included, generics not) 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 that discount usually lowers your plan's liability rather than your own cost-sharing. The 10 negotiated-price drugs are excluded; CMS pays plans a 10 percent subsidy on them in the initial coverage phase instead. The drugs the discount applies to and each phase's rate are in our Georgia Medicare Manufacturer Discount Program guide.10

The Medicare Prescription Payment Plan (M3P)

The Medicare Prescription Payment Plan, available since 2025, lets you pay nothing at the pharmacy for covered drugs and pay your plan in monthly bills instead. It costs nothing to join, doesn't lower your total drug costs, and every Part D plan offers it; your premium is still billed separately.11 Your bill can rise when you fill a new prescription, since fewer months remain to spread it. Medicare says it might help with an unexpected high drug cost early in the year (before September), and probably won't if your costs are steady and affordable.11 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 pair with Original Medicare, and optionally a Medigap policy. Key features:

• Premiums vary by plan; compare your ZIP and your drug list on the Medicare Plan Finder
• Ten standalone PDPs are available in Georgia for 202612

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 202612
• 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 union drug coverage its sponsor has determined is creditable
• VA prescription coverage
• TRICARE prescription coverage
• Indian Health Service, Tribal, or Urban Indian program coverage13

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.14

Annual Election Period (AEP)

The Annual Election Period runs October 15 through December 7 each year.14 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.14

Special Enrollment Periods (SEPs)

Life events such as moving or losing other coverage can open a Special Enrollment Period outside AEP.14 Common ones include moving (a window that runs 2 full months after the move), your plan's contract ending, a declared disaster or emergency, and the 5-star SEP, which lets you switch into a 5-star plan in your area once between December 8 and November 30.15 Leaving a Medicare Advantage plan for a standalone drug plan this way also ends your Medicare Advantage health coverage.15

Monthly SEP for Extra Help and Dual-Eligible Enrollees

Since 2025, dual-eligible and Extra Help enrollees can switch to a standalone Part D plan once a month, replacing the old quarterly SEP; it is unavailable while your plan has flagged you as an at-risk beneficiary under its drug management program.16

Late Enrollment Penalty (LEP)

The Part D late enrollment penalty 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.7

VA and TRICARE count as creditable; employer or union coverage counts only if its sponsor says so in its yearly notice, so keep it. If a drug plan later asks you to confirm past coverage, return its attestation form within 30 calendar days.13 Extra Help enrollees pay no penalty.7 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)4

Those are one- and two-person household limits, not a ceiling on everyone: the limit rises if relatives living with you get at least half their support from you, and SSA excludes some income (all interest and dividends, for one), so apply rather than rule yourself out.4

Resource (asset) limits for full Extra Help (2026):

• $18,090 individual
• $36,100 married couple living together4

These include a burial allowance SSA adds automatically; the lower limits ($16,590, or $33,100 for a couple) apply only if you tell SSA none of your resources will pay for a funeral or burial. Your home and car don't count.4

Some beneficiaries qualify automatically and should not fill out an Extra Help application:

• Full Medicaid dual-eligibles
• QMB, SLMB, QI enrollees (Medicare Savings Programs)
• Supplemental Security Income (SSI) recipients4

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 threshold4

Applying for LIS

Apply through the Social Security Administration:

• Online at ssa.gov/medicare/part-d-extra-help
• By phone at 1-800-772-1213 (TTY 1-800-325-0778); tell the representative you want to set up an appointment to apply for Extra Help4,17

If Georgia Medicaid enrolls you in QMB, SLMB, or QI, you are treated as eligible for Extra Help automatically and do not need to apply.4

Formularies and Drug Coverage

Formulary Definition

A formulary is the list of drugs a Part D plan covers. Each plan picks its own drugs and tiers, so the same drug can cost different amounts across plans, and a plan must notify you if a mid-year change affects a drug you take.18

The Six Protected Classes

Part D plans must include on their formularies all covered Part D drugs in these six classes, a requirement set by section 1860D-4(b)(3)(G) of the Social Security Act:19

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

Plans may apply prior authorization or step therapy in these classes only to new starts (never to antiretrovirals). A plan can still leave a protected-class drug off in limited cases, usually because it covers a therapeutic equivalent; you can appeal.19

Tier Structure

Many Part D plans sort covered drugs into cost-sharing tiers, and a drug on a lower tier generally costs you less. A typical example includes these tiers (your plan's may differ):

• Tier 2: medium copayment, preferred brand-name drugs
• Tier 3: higher copayment, non-preferred brand-name drugs
• Specialty tier: highest copayment, very high-cost drugs18

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

Appeals and Exceptions Process

The first step is a coverage determination: you ask the plan to cover a drug or grant an exception. The plan must decide within 72 hours, or 24 hours if waiting could seriously jeopardize your health, and a missed deadline counts as a denial the plan must send to the Independent Review Entity.20

If the answer is no, Part D appeals run through five levels, each with a filing deadline:21

1. Redetermination by the plan. A fast appeal, when your health can't wait, is generally decided within 72 hours.21
2. Independent Review Entity (IRE). A reviewer outside the plan.
3. Administrative Law Judge (ALJ) hearing. At the Office of Medicare Hearings and Appeals; for calendar year 2026 the amount in controversy must be at least $200.21
4. Medicare Appeals Council.
5. Federal district court. For calendar year 2026 the amount in controversy must be at least $1,960.21

Tiering Exception

If your drug sits on a non-preferred tier, you can ask for a tiering exception to pay the preferred-tier amount. Your prescriber must state that the preferred drug wouldn't work as well for you, would cause adverse effects, or both, and approval isn't automatic.18

Formulary Exception

For a drug not on the formulary, ask the plan to cover it. A refusal can be appealed when your prescriber finds that no formulary drug for your condition would work as well, or that the alternatives would cause adverse effects.19

Quantity Limit Exception

You can also ask the plan to waive a coverage rule, such as a quantity limit.18

Pharmacy Networks

Each plan has its own pharmacy network, and the same drug can cost different amounts across plans.18 Before you enroll, enter your drugs and pharmacy in the Medicare Plan Finder, or ask GeorgiaCares SHIP for free help comparing.8

Medicare Drug Price Negotiation

Under the Inflation Reduction Act, Medicare negotiated prices (Maximum Fair Prices) took effect January 1, 2026 for its first 10 drugs: Eliquis, Jardiance, Xarelto, Januvia, Farxiga, Entresto, Enbrel, Imbruvica, Stelara, and Fiasp/NovoLog. Every Part D plan must keep them on its formulary, but a lower price doesn't automatically lower your copay, so compare each plan's cost for your drug.5 For the full Georgia breakdown, see Georgia Medicare Drug Price Negotiation.

Georgia Part D Carrier Landscape

Standalone PDPs in Georgia (2026)

Ten standalone drug plans are available in Georgia for 2026.12 Carriers and premiums change yearly, so compare current plans on the Plan Finder rather than by brand name.

Plan Variety

Georgia is a high-Medicare-Advantage state. As of March 2026, CMS counted 2,024,284 people with Medicare in Georgia: 1,132,173 in Medicare Advantage and other health plans, and 892,111 in 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 2026.12

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. 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 65 in 2020 but skipped Part D, paying cash for occasional medications on the assumption he could enroll later. Five years later (60 months), in 2025, he is prescribed a statin and applies during AEP for January 2026 coverage.

His plan calculates the penalty at 1 percent for each of those 60 uncovered months, applied to the $38.99 national base beneficiary premium and rounded to the nearest $0.10. That 60 percent penalty rides on his plan premium for life.7

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.

Before the IRA redesign, she would have had no annual cap and kept paying cost-sharing even in the catastrophic phase.1

Under the redesigned 2026 benefit:1

• January 2026: Enbrel filled; she pays her plan's deductible (no more than $615), then 25% coinsurance until her out-of-pocket spending reaches $2,100
• Reaches $2,100 OOP by mid-to-late January
• February through December: $0 for Enbrel
• Annual total: $2,100

Note: Enbrel also has a Medicare-negotiated price from January 2026, which lowers its price but not automatically her copay; the $2,100 cap applies either way.5,1

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.22

She applies through Social Security and, with savings under the resource limit, qualifies for the full subsidy described above.4

Patricia chooses Humana Premier Rx benchmark plan. Her annual Part D cost:4

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

Henry 75 Athens: MA-PD to PDP Switch

Henry has been enrolled in a Humana MA-PD for 3 years with a $0 premium.12 His new prescription for a specialty medication is not on the Humana formulary, requiring step therapy and prior authorization.

Henry compares standalone PDPs available with Original Medicare:

• WellCare Wellness Rx: lowest premium, but doesn't cover his drug
• Humana Premier Rx: covers his drug, at a higher premium
• AARP UHC Preferred Rx: covers his drug, with a lower premium and lower copays than Humana's

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/month23
• Total: $411.90/month

Compared to his MA-PD ($202.90/month Part B + $0 plan), Henry pays $209 more per month but gains:23

• 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 it, switching generally takes a Special Enrollment Period.14

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.4

5. Not appealing a formulary denial. A tiering exception needs a supporting statement from your prescriber, and a denied exception can be appealed.18,19

6. Not checking Star Ratings. Weigh a plan's quality rating alongside its cost; if a 5-star plan is available in your area, you can switch into it once between December 8 and November 30.15 GeorgiaCares SHIP can help you compare.8
