What Medicare Part D Covers — and What It Costs in 2026
Medicare Part D is prescription drug coverage. In 2026, NC residents pay a monthly plan premium (typically $0–$80/month for standalone PDPs), a deductible of up to $590 before coverage starts on most brand drugs, and a copay or coinsurance per prescription based on what tier the drug falls on. The biggest change for 2026: once your out-of-pocket drug costs reach $2,000 in a calendar year, you pay $0 for covered drugs for the rest of the year. The old coverage gap (donut hole) is eliminated.
The single most important thing to do before choosing a Part D plan is to enter your specific medications into a comparison tool. Two plans with identical premiums can differ by hundreds or thousands of dollars per year in actual drug costs depending on tier placement and preferred pharmacy networks. Use the GenerationHealth comparison tool or call (828) 761-3326 to run this analysis for your NC county. NC License #10447418.

The Five-Tier Formulary — What You Pay Per Prescription
Every Medicare Part D plan and Medicare Advantage drug plan (MAPD) uses a tiered formulary. Each drug on the plan’s covered drug list is assigned to a tier, and each tier has its own copay or coinsurance. Understanding where your medications land on the formulary is more important than comparing premiums.
| Tier | Drug Type | Deductible Applies? | Typical Copay / Coinsurance | NC Plan Range |
|---|---|---|---|---|
| Tier 1 — Preferred Generic | Generic drugs preferred by the plan | Usually waived — $0 deductible | $0–$5 flat copay | $0–$5 |
| Tier 2 — Generic | Non-preferred generics and some generics | Often waived on Tier 2 | $5–$15 flat copay | $5–$18 |
| Tier 3 — Preferred Brand | Preferred brand-name drugs | Usually applies ($590 max) | $25–$50 flat copay | $25–$55 |
| Tier 4 — Non-Preferred Brand | Non-preferred brands and some generics | Yes — full deductible applies | $60–$100 copay or 25–40% coinsurance | $60–$115 or 25%+ |
| Tier 5 — Specialty | High-cost specialty and biologic drugs | Yes — full deductible applies | 25–33% coinsurance of drug cost | 25%–33% (can be thousands) |
A plan with a $0 monthly premium that places your brand-name blood pressure medication on Tier 4 can cost you $1,200 more per year than a plan with a $28/month premium that places the same drug on Tier 3. This is the single most common and expensive Part D mistake. Always run your actual drug list through a plan comparison tool before enrolling or staying in your current plan. Plans can change their formularies every January 1. Call (828) 761-3326. NC License #10447418.
How the 2026 Part D Calendar Year Works
Part D costs move through distinct phases each calendar year. The most important change for 2026: the coverage gap (donut hole) is gone. There are now just three phases, and the third phase caps your total out-of-pocket at $2,000.
Deductible Phase
You pay 100% of drug costYou pay the full negotiated cost for covered drugs until you have spent your plan’s deductible amount (up to $590 for 2026). Most plans waive the deductible for Tier 1 and Tier 2 drugs — you pay the copay from day one for generics. The deductible most commonly applies to Tier 3, 4, and 5 drugs. Your spending during this phase counts toward your $2,000 annual OOP cap. Resets every January 1. Call (828) 761-3326. NC License #10447418.
Initial Coverage Phase
You pay your tier copay or coinsuranceAfter your deductible is met, you pay your tier copay or coinsurance for each covered prescription. Your plan pays the rest. This is the phase where most beneficiaries spend most of their year. Copays range from $0–$5 for Tier 1 generics up to 33% coinsurance for Tier 5 specialty drugs. Every dollar you pay out-of-pocket in this phase counts toward your $2,000 annual cap. Call (828) 761-3326. NC License #10447418.
Catastrophic Coverage Phase (After $2,000 OOP Cap)
You pay $0 for covered drugsOnce your total out-of-pocket drug costs reach $2,000 in the calendar year, you enter the catastrophic coverage phase and pay $0 for all covered drugs for the rest of that year. This is new for 2026 under the Inflation Reduction Act and permanently eliminates the old coverage gap (donut hole). Beneficiaries on high-cost specialty or brand medications will reach this phase faster. Resets January 1. Call (828) 761-3326. NC License #10447418.
The $2,000 cap is genuinely transformative for beneficiaries on expensive specialty drugs. Prior to 2024, a patient on a $7,000/month biologic could owe $3,000–$5,000+ in a year after clearing the coverage gap. In 2026, the same patient owes a maximum of $2,000 total — and once they hit that number in the first few months, the rest of the year is $0.
What this means practically: if you are on a high-cost specialty medication (cancer drugs, MS treatments, biologics for rheumatoid arthritis, etc.), make sure your plan’s formulary covers your drug before you enroll — because once you’re in, switching plans mid-year requires a Special Enrollment Period. Call (828) 761-3326 and I’ll pull every NC plan that covers your specific drug and show you the total annual cost under each. NC License #10447418.
Extra Help — Reducing Part D Costs for Lower-Income NC Residents
Extra Help (also called the Low Income Subsidy, or LIS) is a federal program that reduces or eliminates Medicare Part D costs for NC beneficiaries with limited income and resources. It is dramatically underutilized — many eligible people never apply.
Full Extra Help (Level 1 LIS)
Partial Extra Help (Level 2 LIS)
NC residents who qualify for QMB (Qualified Medicare Beneficiary) or are enrolled in Medicaid are automatically enrolled in Full Extra Help. You do not need to apply separately. If you are near the income limits and unsure whether you qualify, call (828) 761-3326 — Rob can confirm eligibility in a few minutes. NC License #10447418.
Part D IRMAA — Higher-Income Surcharges for 2026
If your 2024 tax return shows income above $106,000 (individual) or $212,000 (married filing jointly), you pay an IRMAA surcharge on top of your Part D plan premium. This surcharge is paid directly to Medicare and added to your monthly Social Security deduction or billed quarterly.
| 2024 Individual Income | 2024 Joint Filing Income | 2026 Part D IRMAA Surcharge | Total Added to Plan Premium |
|---|---|---|---|
| $106,000 or less | $212,000 or less | $0 — no surcharge | Pay plan premium only |
| $106,001 – $133,000 | $212,001 – $266,000 | +$13.70/mo | Plan premium + $13.70/mo |
| $133,001 – $167,000 | $266,001 – $334,000 | +$35.30/mo | Plan premium + $35.30/mo |
| $167,001 – $200,000 | $334,001 – $400,000 | +$57.00/mo | Plan premium + $57.00/mo |
| $200,001 – $500,000 | $400,001 – $750,000 | +$78.60/mo | Plan premium + $78.60/mo |
| Above $500,000 | Above $750,000 | +$85.80/mo | Plan premium + $85.80/mo |
IRMAA is based on your income from two years ago (2024 income determines 2026 IRMAA). If your income has dropped significantly due to retirement, marriage, divorce, or loss of a spouse, you can appeal your IRMAA determination using SSA Form SSA-44. Call (828) 761-3326. NC License #10447418.

How to Find the Lowest-Cost Part D Plan for Your Medications in NC
- Never compare only premiums. A $0-premium plan can cost $1,200 more per year than a $28/month plan if your drugs are on different tiers. Total annual drug cost = deductible + copays + coinsurance, compared across every plan in your county. NC License #10447418.
- Enter your complete drug list with exact dosages. Use the GenerationHealth plan comparison tool and enter every medication you take with the exact dose and quantity. The comparison will show your estimated annual drug cost under every plan available in your NC county. Call (828) 761-3326. NC License #10447418.
- Check preferred pharmacy networks. Most Part D plans have preferred pharmacy networks where your copays are lower (sometimes by 30–50%). Using an out-of-network pharmacy can double or triple your copay on the same drug. Confirm your pharmacy is in-network — or identify the nearest preferred network pharmacy — before enrolling.
- Re-evaluate every October during Annual Enrollment. Plans change formularies, premiums, and pharmacy networks every January 1. A plan that was optimal in 2025 may not be optimal in 2026. Re-run your drug list comparison during the Annual Enrollment Period (Oct 15 – Dec 7) every year. Call (828) 761-3326. NC License #10447418.
- If you are on Extra Help, confirm plan benchmark eligibility. Extra Help covers your premium up to the regional benchmark amount. If your plan premium exceeds the benchmark, you owe the difference. At the start of each year, confirm your plan is still benchmark-eligible or CMS will auto-enroll you in a benchmark plan. Call (828) 761-3326. NC License #10447418.
Part D plan availability, formularies, premiums, and preferred pharmacy networks vary by NC county and zip code. Always compare using your specific location. Call (828) 761-3326 for a complete drug cost analysis for your county. NC License #10447418.

What is the Medicare Part D deductible for 2026?
The maximum Medicare Part D standard deductible for 2026 is $590. Not every plan charges the full deductible. Many plans offer $0 deductibles on Tier 1 and Tier 2 generic drugs, meaning you pay your copay from day one for those medications. The deductible most commonly applies to Tier 3 brand-name and higher-tier drugs. Call (828) 761-3326. NC License #10447418.
What is the Part D out-of-pocket cap for 2026?
The Medicare Part D out-of-pocket cap for 2026 is $2,000. Once your total out-of-pocket drug costs reach $2,000 in a calendar year, you pay $0 for covered drugs for the rest of that year. This permanently eliminates the old coverage gap (donut hole). The cap applies to all Part D and MAPD plans and resets on January 1. Call (828) 761-3326. NC License #10447418.
How do Medicare Part D drug tiers work in 2026?
Most NC Part D plans use five tiers. Tier 1 (preferred generics): $0–$5 copay. Tier 2 (generics): $5–$15 copay. Tier 3 (preferred brand): $25–$50 copay. Tier 4 (non-preferred brand): $60–$100 copay or 25–40% coinsurance. Tier 5 (specialty): 25–33% coinsurance. Your actual drug costs depend on which tier your specific medications fall on.

Who qualifies for Extra Help with Medicare Part D in North Carolina?
Extra Help is available to NC beneficiaries with income below roughly 150% of the federal poverty level — approximately $22,590/year for an individual in 2026. Full Extra Help covers your Part D premium, eliminates the deductible, and caps drug copays at $1.10–$11.20 per prescription. Apply through Social Security at SSA.gov or call 1-800-772-1213. NC residents with QMB or Medicaid are enrolled automatically. Call (828) 761-3326. NC License #10447418.
What is the Medicare Part D IRMAA surcharge for 2026?
IRMAA begins when 2024 individual income exceeds $106,000 or joint income exceeds $212,000. The surcharge ranges from $13.70/month to $85.80/month and is added on top of your plan premium. IRMAA is based on your 2024 tax return. If your income has dropped significantly since 2024, you can appeal using SSA Form SSA-44. Call (828) 761-3326. NC License #10447418.
Is there a penalty for late enrollment in Medicare Part D?
Yes — and it is permanent. For every month you go without creditable drug coverage after your IEP ends (63+ consecutive days), you owe 1% of the national base beneficiary premium ($36.78 in 2026) added to your plan premium for life. Two years without coverage adds approximately $8.80/month permanently. VA coverage, most employer plans, TRICARE, and Medicaid all count as creditable coverage. Call (828) 761-3326. NC License #10447418.
