Medicare Part D in 2026: $2,100 Cap, Key Dates for Pittsburgh

People in Pittsburgh can choose from 84 Medicare Advantage plans for 2027, against 96 this year. Nine of this year's plans are gone, 8 are new to Allegheny County, and 35 that continue have changed something in their terms, 11 of them under a new name.

How Medicare Part D works in 2027: deductible, the out-of-pocket cap, and the three phases for Pittsburgh readers.

PITTSBURGH — If you take prescription drugs and rely on Medicare, 2027 brings a set of numbers and dates worth writing on the fridge. Part D — the drug coverage side of Medicare — has a hard out-of-pocket cap of $2,400 in 2027 (up from $2,100 in 2026), a deductible that can be no higher than $700 in 2027, and just three coverage phases instead of four. The old "donut hole" is gone.

But the rules only help if you're enrolled in the right window. In Allegheny County, where Pittsburgh sits, shoppers have real choices this fall — and real deadlines that can cost money if missed.

The dates that matter most

Medicare's calendar isn't complicated once you see it laid out, but the windows don't overlap the way people expect.

Initial Enrollment Period (IEP). This is your personal, one-time, seven-month window around your 65th birthday — the three months before, your birthday month, and the three months after. This is when most people first pick up Part D or a Medicare Advantage plan with drug coverage (called MA-PD).

Annual Enrollment Period (AEP): October 15 – December 7. Anyone on Medicare can join, switch, or drop a Part D or Medicare Advantage plan. Choices made here start January 1.

Medicare Advantage Open Enrollment Period (MA-OEP): January 1 – March 31. If you're already in a Medicare Advantage plan on January 1 and it isn't fitting, you get one chance during these three months to switch to another Medicare Advantage plan or drop back to Original Medicare and pick up a stand-alone drug plan. You cannot use this window to join Medicare Advantage for the first time.

Special Enrollment Periods (SEPs). Life events — moving, losing employer coverage, qualifying for Extra Help — can open a private window outside the ones above.

What happens if you miss a window

The most common miss is the very first one. If you don't sign up for Part D when you're first eligible, and you go 63 days or more without "creditable" drug coverage (coverage at least as good as Medicare's), you can owe a late enrollment penalty when you finally join. That penalty is added to your monthly premium and, in most cases, stays with you for the rest of the time you have Part D.

Miss the Annual Enrollment Period and, in most cases, you're locked into your current plan for another calendar year unless you qualify for a Special Enrollment Period. That matters because plans change every year — your copays, the pharmacies in network, and the list of covered drugs (the formulary) can all shift on January 1. A plan that fit in 2026 may not fit in 2027.

How the dates interact with the 2027 rules

Here's where timing meets money. Your out-of-pocket cap resets each calendar year — so what you spend in 2026 doesn't roll into 2027. If you're switching plans during AEP, your new plan starts your deductible and your cap over on January 1.

There are now three phases in Part D:

1. Deductible phase — you pay the full negotiated price until you hit the plan's deductible (no more than $615 in 2026 ($700 in 2027)). 2. Initial coverage — you pay a share (a copay or coinsurance) while the plan pays the rest. 3. Catastrophic coverage — once your out-of-pocket spending on covered drugs hits $2,100 in 2026 ($2,400 in 2027), you pay $0 for covered drugs the rest of the year.

Also worth knowing: the Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly installments instead of paying big amounts at the pharmacy counter. You can opt in through your Part D plan at any time, but signing up before a costly month starts is usually smoother than signing up mid-fill.

The Pittsburgh picture

Allegheny County is home to nearly 250,000 people age 65 or older, and the plan landscape reflects that. There are 84 Medicare Advantage plans available in the county in 2027, offered by 16 carriers, and the vast majority of those bundle in Part D drug coverage. That means most Pittsburgh shoppers who want drug coverage will get it through a Medicare Advantage plan rather than a stand-alone Part D plan.

If you'd rather keep Original Medicare and add a separate drug plan, note that stand-alone Part D options in this county are limited — another reason to look carefully during the October 15 to December 7, 2026 window rather than waiting.

A quick timing checklist

• Turning 65 in 2027? Mark your seven-month Initial Enrollment Period on the calendar now.
• Already on Medicare? Use October 15 – December 7, 2026 to compare plans for 2027, even if you're happy — plans change annually.
• Already in a Medicare Advantage plan on January 1? You have until March 31 to make one change if the fit isn't right.
• Higher income? If your income is above $109,000 (single filer, 2026), an IRMAA surcharge may be added to your Part B and Part D premiums.
