How the stages work in 2027
- Deductible. You pay the full plan price for covered drugs until you meet your plan's deductible, no more than $700.
- Initial coverage. You pay your plan's copays or coinsurance.
- Catastrophic coverage. Once your out-of-pocket costs reach $2,400, you pay nothing for covered drugs through December 31.
There's no coverage gap: it ended in 2025. See whether the donut hole still exists.
If you'll reach the cap
People on costly drugs can hit the cap in the first months of the year. The Medicare Prescription Payment Plan lets you pay those costs in monthly bills from your plan instead of at the pharmacy. If you're in it for 2026 and keep the same plan, it renews for 2027 unless you opt out. It doesn't lower your total cost.
Choosing a 2027 drug plan in Oregon
For 2027, Oregon has 8 standalone Part D plans from 4 companies, offered statewide in Part D region 30 with Washington, plus Medicare Advantage plans with drug coverage that vary by county. The cap is the same in every plan, but premiums, deductibles, formularies and pharmacy networks aren't. Open Enrollment ends December 7, 2026. You can check your drugs at PlanMatch or Medicare.gov's Plan Finder, or request a call from a licensed insurance agent. If your income is limited, see Extra Help in Oregon.

Frequently asked questions
What is the maximum Part D deductible for 2027?
$700, up from $615 in 2026. Plans can set a lower deductible or none, and insulin and recommended vaccines aren't subject to it.
What counts toward the cap?
What you pay for covered drugs in the deductible and initial coverage stages, plus amounts paid on your behalf by Extra Help, the Indian Health Service and certain other programs. Premiums and drugs your plan doesn't cover don't count.
Does the cap reset if I change plans mid-year?
No. Your spending toward the cap carries over within the same calendar year if you switch Part D plans. It starts over each January 1.
