Medicare Part D

How Medicare Part D Works in Mount Vernon Under the Cap

MOUNT VERNON, N.Y. — Starting January 1, 2027, the amount any person with Medicare Part D can pay out of pocket for covered prescription drugs in a single year is capped at $2,400. Once you hit that number, your covered medications cost you nothing for the rest of the calendar year. The cap was $2,000 in 2025 and $2,100 in 2026 — it's the biggest structural change to Medicare drug coverage in a generation.

Mount Vernon retirees get a firmer ceiling on drug costs in 2027

If you live in Mount Vernon and take expensive medications — for cancer, blood thinners, MS, rheumatoid arthritis, diabetes, or almost any specialty drug — this cap is the part of Medicare most likely to change your year.

The coverage gap is gone. Here's what replaced it.

For decades, Part D had four phases, including the dreaded "donut hole" where people paid a much bigger share of their drug costs partway through the year. That gap was eliminated in 2025 and remains gone in 2027.

Today, Part D has three straightforward phases:

• Deductible phase. You pay full negotiated price until you meet your plan's deductible. In 2027, no Part D plan can set a deductible higher than $700. Some plans set it lower.
• Initial coverage phase. You pay a copay or coinsurance for each prescription; the plan pays the rest. Your out-of-pocket spending here counts toward the cap.
• Catastrophic phase. Once your true out-of-pocket costs reach $2,400 in 2027, you pay nothing for covered drugs for the rest of the year.

That's it. No more donut hole math, no more surprise price jump in July.

What counts toward the $2,400 — and what doesn't

This is where mistakes happen. The cap applies to covered Part D drugs — medications on your plan's formulary bought at a network pharmacy. Things that generally do not count toward the $2,400:

• Your monthly Part D premium.
• Drugs your plan doesn't cover.
• Drugs covered under Part B (like most infusions given in a doctor's office).
• Over-the-counter medications.

If you take a drug and it's not on your plan's formulary, you could spend a lot without getting any closer to the cap. That's why matching your medication list to a plan's formulary during Annual Enrollment matters so much.

The Medicare Prescription Payment Plan: spreading $2,400 across the year

A $2,400 ceiling is a relief, but hitting it in January or February can still hurt a fixed-income budget. To help, Medicare offers the Medicare Prescription Payment Plan — an optional program, sometimes called "M3P," that lets you spread your out-of-pocket drug costs over monthly payments instead of paying the pharmacy in one lump when you pick up your prescription.

Here's how it works in plain terms:

• You still owe the same total amount for the year. The payment plan doesn't lower your costs; it smooths them.
• Instead of paying the pharmacy, you pay nothing at the counter for covered drugs. Your Part D plan bills you monthly for what you owe.
• You can opt in at any time during the year by contacting your Part D or Medicare Advantage drug plan.
• If you miss payments, you can be removed from the program (though you keep your drug coverage).

This program tends to help most if you have high drug costs early in the year. If your prescriptions are inexpensive and spread out, signing up may just add a bill to track. There is no penalty for skipping it.

Common mistakes to avoid this Annual Enrollment Period

Annual Enrollment runs October 15 through December 7, 2026, and any change you make takes effect January 1, 2027. Mount Vernon is in Westchester County, where 62 Medicare Advantage plans from 15 carriers are offered for 2027 — down from 77 plans and 16 carriers in 2026, with 54 continuing, 8 new, 20 not returning, and 3 renamed. Eighteen continuing plans change something in their terms, so a careful comparison is worth an afternoon.

A few pitfalls to steer around:

1. Assuming your current plan is unchanged. Formularies, tiers, and pharmacy networks reset each year. Read the Annual Notice of Change your plan mailed in September. 2. Choosing on premium alone. A low monthly premium with a $615 deductible and a drug on a high tier can cost more than a higher-premium plan with better coverage of your specific medications. 3. Forgetting IRMAA. Higher-income beneficiaries pay an Income-Related Monthly Adjustment Amount on top of their Part D premium. For 2026, IRMAA surcharges begin above $109,000 in income for a single filer (based on your 2024 tax return). 4. Waiting until December. Pharmacists, plan phone lines, and SHIP counselors get slammed the final week. Start in October.

If you're in a Medicare Advantage plan and change your mind after January 1, you have a second window — the Medicare Advantage Open Enrollment Period, January 1 through March 31 — to switch Advantage plans or return to Original Medicare.

Quick FAQ

Does the $2,100 cap apply to Medicare Advantage plans too? Yes, as long as the Advantage plan includes Part D drug coverage (most do). The cap covers your out-of-pocket spending on covered prescription drugs, whether your drug coverage comes through a stand-alone Part D plan or a Medicare Advantage plan with drugs built in.

If I hit the $2,400 cap in June, do I really pay nothing for my drugs the rest of the year? For covered drugs at a network pharmacy — yes, nothing more for the remainder of 2027. In January, the counter resets and you start over.

Do I have to sign up for the Prescription Payment Plan? No. It's completely optional. You can join before the plan year starts or at any time during 2027 by calling the drug plan on the back of your Medicare card.

What if I can't afford my drugs even with the cap? Ask about Extra Help (the Low-Income Subsidy), which can dramatically reduce Part D costs for people with limited income and resources. New York State also runs EPIC, a program that helps residents 65+ with drug costs. You can apply for Extra Help at ssa.gov or by calling Social Security.

Where to get answers you can trust

For anything specific to your situation — your drugs, your income, your pharmacy, your doctors — talk to a source that isn't trying to sell you something:

• Medicare.gov, especially the Plan Finder tool, which lets you enter your medications and see how each plan would price them.
• 1-800-MEDICARE (1-800-633-4227), 24 hours a day, 7 days a week.
• New York's SHIP, called HIICAP (Health Insurance Information, Counseling and Assistance Program), offers free one-on-one counseling. Westchester County residents can reach HIICAP through the county's Department of Senior Programs and Services.
• Social Security at ssa.gov or 1-800-772-1213 for Extra Help applications.

The rules changed to make drug costs more predictable. Use the next few weeks to make sure your coverage matches the medications you actually take — that's where the new cap does its real work.
