Waterbury Medicare Part D: no donut hole, new $2,100 ceiling

WATERBURY, Conn. — If you take prescription drugs and rely on Medicare, 2026 brings some of the most important Part D changes in years. There's a new out-of-pocket ceiling, a higher maximum deductible, and — for the second year running — no more "donut hole." Here's a plain-English look at how the coverage works now, and what Waterbury residents should keep in mind before the enrollment window closes.

The big headline: a $2,100 out-of-pocket cap

Starting in 2026, no one with Medicare Part D will pay more than $2,100 out of pocket for covered prescription drugs in a calendar year. Once you hit that ceiling, your covered prescriptions cost you nothing for the rest of the year.

This cap applies whether your Part D coverage comes through a stand-alone drug plan or is built into a Medicare Advantage plan that includes drug coverage. It's a program-level rule set by Medicare, so it works the same way for everyone enrolled.

The three phases of Part D coverage in 2026

Since the coverage gap (the old "donut hole") was eliminated in 2025, Part D now has just three phases instead of four:

1. Deductible phase. You pay the full negotiated price of your drugs until you meet your plan's deductible. In 2026, the maximum deductible any plan can charge is $615. Some plans set theirs lower.

2. Initial coverage phase. After the deductible, you pay a copay or coinsurance for each prescription, and your plan pays the rest. You stay in this phase until your out-of-pocket spending on covered drugs reaches $2,100.

3. Catastrophic phase. Once you hit the $2,100 cap, you pay $0 for covered drugs for the remainder of the calendar year.

That's it. No coverage gap, no confusing middle stretch where costs suddenly jumped.

The Medicare Prescription Payment Plan — a smoothing option

One of the most overlooked tools in Part D is the Medicare Prescription Payment Plan. It doesn't lower what you owe, but it lets you spread your drug costs across the year in monthly installments instead of paying big amounts at the pharmacy counter.

This can be helpful if you take an expensive medication early in the year and would otherwise hit your deductible in a single trip. Enrollment is voluntary, free to join, and you can sign up through your Part D plan. Learn more at medicare.gov.

What Waterbury residents should know about availability

Waterbury is in New Haven County, where Medicare plan availability is set at the county level — not by ZIP code or city. That means every Waterbury resident chooses from the same pool of stand-alone Part D plans and Medicare Advantage plans with drug coverage as the rest of New Haven County.

Common mistakes to avoid

• Assuming your current plan is still the right fit. Plans change their formularies (the list of covered drugs), pharmacy networks, and cost-sharing every year. Review your Annual Notice of Change letter every fall.
• Missing the Annual Enrollment Period. It runs October 15 through December 7 each year. Changes made during this window take effect January 1.
• Forgetting about IRMAA. If your income is above $109,000 (single filer, 2026), you'll pay an income-related surcharge on top of your Part D premium. This is based on your tax return from two years earlier.
• Skipping the Medicare Advantage Open Enrollment Period (January 1 – March 31), which gives Medicare Advantage members one more chance to switch plans or return to Original Medicare.
