SAPULPA, Okla. — If you take prescription drugs and you're on Medicare, the Part D changes that took hold in 2026 carry into 2027. There's a firm ceiling on what you'll pay out of pocket at the pharmacy, the old "donut hole" is gone, and the whole system runs in just three phases instead of four.
Here's a plain-language walk-through of how Part D drug coverage works for 2027, what the key numbers are, and where Sapulpa residents can get help sorting it out.
What Part D is, in one paragraph
Part D is Medicare's prescription drug coverage. It's sold by private insurance companies that follow rules set by Medicare. You can get it as a stand-alone drug plan added to Original Medicare, or built into a Medicare Advantage plan. Either way, the program-level rules — like the yearly deductible limit and the out-of-pocket cap — are the same across the country, including here in Sapulpa.
The three phases for 2027
Since 2025, Part D has three payment phases instead of four. Here's how they flow across a calendar year.
1. Deductible phase. You pay the full negotiated price for your drugs until you meet your plan's deductible. The maximum deductible a Part D plan can charge is $615 in 2026 and $700 in 2027. Some plans charge less, and some charge nothing at all for certain drug tiers — that's a plan-by-plan detail.
2. Initial coverage phase. After the deductible, you pay a share of the cost (a copay or coinsurance) and your plan pays the rest. You stay in this phase until your out-of-pocket spending on covered drugs hits the yearly cap.
3. Catastrophic phase. Once your out-of-pocket spending reaches the yearly cap — $2,100 in 2026 and $2,400 in 2027 — you pay nothing more for covered Part D drugs for the rest of the year. This hard cap applies to everyone in a Part D plan.
The old coverage gap — the "donut hole" — is officially retired. You will not hit a middle stretch where your costs suddenly jump.
The $2,100 cap, explained
The $2,100 out-of-pocket limit is the number most people want to understand. It counts what you pay for covered Part D drugs — deductibles, copays, and coinsurance. It does not count your monthly premium, and it does not count drugs your plan doesn't cover.
Once you cross $2,100 in a calendar year, you're done paying for covered drugs until January 1 rolls around and the count resets.
Spreading costs with the Payment Plan
If a big prescription bill early in the year would be hard to handle, Medicare now offers the Medicare Prescription Payment Plan. Instead of paying the pharmacy at pickup, you can choose to have your plan bill you monthly, spreading your drug costs more evenly across the year. It doesn't lower your total cost, but it can make cash flow easier. Signing up is free and voluntary. You can ask your Part D plan how to opt in.
Higher-income surcharges (IRMAA)
Most people pay only their plan's premium. But if your income is above a certain level — starting above $109,000 for a single filer in 2026 — you'll pay an extra amount called IRMAA on top of your Part D premium. Social Security bills this separately. If your income has recently dropped (say, because you retired), you can ask Social Security to reconsider.
Enrollment windows to remember
- Annual Enrollment Period: October 15 – December 7. This is when most people can join, switch, or drop a Part D plan for the following year.
- Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, you can make one change during this window.
Sapulpa is in Creek County, where Medicare beneficiaries have a range of stand-alone Part D plans and Medicare Advantage plans with drug coverage to compare. The specific plans available can change each year, so it's worth re-checking during open enrollment even if you're happy with what you have.

How Medicare Part D works in 2027
The old coverage gap (“donut hole”) is eliminated as of 2025 (three phases now). There’s now a hard yearly cap of $2,100 on what you pay out of pocket for covered drugs, and you can spread those costs across the year with the Medicare Prescription Payment Plan.
