Watertown Medicare Part D 2027: Coverage Gap

WATERTOWN, S.D. — On Jan. 1, 2027, the Part D out-of-pocket cap moves to $2,400, up from $2,100 in 2026. The hard yearly ceiling on what you pay for covered prescriptions — one of the biggest shifts in the history of Medicare's drug benefit — continues, just at a slightly higher number. For people in Codington County who take costly medications, there are a few decisions worth understanding before the Annual Enrollment Period closes on Dec. 7.

Here's what actually changed, what to watch out for, and where to get free help.

The Part D cap, in plain English

In 2027, once your out-of-pocket spending on covered Part D drugs reaches $2,400, you pay nothing more for those drugs for the rest of the year. This is a hard ceiling set by Medicare, and it applies whether your drug coverage comes through a stand-alone Part D plan or is built into a Medicare Advantage plan that includes drug coverage.

A few things to keep in mind:

• The cap counts what you pay for covered drugs — deductibles and copays included. Monthly premiums do not count toward the cap.
• Only drugs on your plan's formulary (its covered-drug list) count. If you fill a drug your plan doesn't cover, that spending typically won't count toward the $2,100 in 2026 ($2,400 in 2027).
• The maximum Part D deductible any plan can charge in 2026 is $615. Plans can charge less, but not more.

Goodbye, "donut hole"

For years, Medicare's drug benefit had a confusing middle stage called the coverage gap, or "donut hole," where your share of costs changed partway through the year. That gap was eliminated in 2025.

Part D now has three straightforward phases:

1. Deductible phase — you pay the full negotiated price until you meet your plan's deductible (up to $700 in 2027). 2. Initial coverage phase — you pay copays or coinsurance until your out-of-pocket total hits $2,400. 3. Catastrophic phase — you pay nothing more for covered drugs for the rest of the year.

That's it. No more surprise price jumps mid-year.

The Medicare Prescription Payment Plan: spreading the cost

Here's the piece a lot of people miss. Even with a $2,400 cap in 2027, hitting that ceiling in January or February can still sting if you take an expensive specialty drug. To help, Medicare offers the Medicare Prescription Payment Plan — an optional program that lets you spread your out-of-pocket drug costs across monthly bills instead of paying it all at the pharmacy counter.

A few important points:

• It's free to sign up, and it's offered through your Part D or Medicare Advantage drug plan.
• It doesn't lower your total costs — it just smooths them out over the calendar year.
• You can enroll before the plan year starts or any time during the year. If you sign up mid-year, the remaining balance is spread across the months left.
• You still pick up your prescriptions the same way; the plan bills you monthly.

This program is most helpful for people whose drug costs are front-loaded — for example, someone on a pricey medication who would otherwise pay hundreds of dollars in a single January trip to the pharmacy.

Common mistakes to avoid

A few pitfalls we see every year in the Watertown area and beyond:

• Assuming every drug is covered. Formularies change. Before you renew, check that each of your prescriptions is still on your plan's 2027 list.
• Skipping the Annual Notice of Change. Your plan mails an ANOC each fall showing what's changing. Read it — even small tier changes can affect what you pay.
• Forgetting about IRMAA. Higher-income beneficiaries pay a Part D surcharge (IRMAA) on top of their premium. For 2026, IRMAA starts above $109,000 in income for a single filer (based on your 2024 tax return).
• Waiting until January to ask questions. The Annual Enrollment Period runs Oct. 15 through Dec. 7. Changes made during that window take effect Jan. 1.

What Watertown residents should know locally

Watertown is in Codington County, where Medicare beneficiaries can choose from stand-alone Part D plans as well as Medicare Advantage plans that include drug coverage. The number of plans available and the specific drugs each one covers vary — which is why comparing options on Medicare's Plan Finder each fall matters more than picking based on a familiar name.
