Each year CMS and the IRS set new Medicare amounts that take effect January 1, and plans change their premiums, drug lists and networks. This page lists what changed for 2026, what is already confirmed for 2027, and what is still to come, with the Oregon details that matter. Open Enrollment for 2027 coverage runs October 15 to December 7, 2026.

CMS usually releases the next year's Part A, Part B and IRMAA amounts in November in its fact sheet on Medicare Parts A and B premiums and deductibles. Until it does, don't rely on estimates. The full 2026 amounts are on Medicare costs in Oregon, and 2027 amounts are added to Medicare costs in 2027 as they are published.
What changed for 2026
- Part B. The standard premium is $202.90 a month and the deductible $283.
- Part D cap. The yearly out-of-pocket cap for covered drugs is $2,100. There is no coverage gap.
- First negotiated drug prices. Medicare's negotiated prices for the first 10 drugs selected under the Inflation Reduction Act took effect January 1, 2026.
- Medicare Prescription Payment Plan. Since 2025, every Part D plan, including Medicare Advantage plans with drug coverage, must let you spread out-of-pocket drug costs into monthly payments. You must sign up with your plan.
What is confirmed for 2027
- Part D. The out-of-pocket cap rises to $2,400 and the highest deductible a plan may charge to $700. Covered insulin stays at no more than $35 for a month's supply.
- Negotiated prices for 15 more drugs. CMS announced in November 2025 negotiated prices for a second group of 15 Part D drugs, including Ozempic, Rybelsus and Wegovy, effective January 1, 2027. Your cost still depends on your plan's drug list and tier, so check how each plan covers your drugs for 2027.
- Medicare Advantage limits. The highest out-of-pocket limit a plan may set rises to $9,850 in network and $14,800 combined. Each plan sets its own limit at or below these amounts.
- Medigap. Plan K's limit is $8,360, Plan L's $4,180, and the high-deductible Plan G/F deductible $3,050.
- Extra Help. The most a person with Extra Help pays is $5.80 for a generic and $14.40 for a brand-name drug, and less for some people with full Medicaid. 2027 income and resource limits come out early in 2027. See Extra Help in Oregon.
- Still to come. The 2027 Part A and Part B premiums and deductibles and the IRMAA brackets (which will use 2025 tax returns).
What is changing in Oregon for 2027
- Plan choices. CMS 2027 data show 61 Medicare Advantage plans open to everyone in their service areas in Oregon, from 14 companies, plus 26 special needs plans, and 8 standalone Part D plans. Choices vary a lot by county: Multnomah County has 32 Medicare Advantage plans open to everyone, while Grant, Harney, Lake, Umatilla and Union counties have none (only employer group plans) and Curry County has only a special needs plan. See your county.
- Plans ending. Six companies stop selling Medicare Advantage plans in some Oregon counties for 2027. If your plan is ending, you will get a non-renewal letter. Choose a new plan by December 31, 2026 to avoid a gap in coverage; you also have a special enrollment period through February 28, 2027, and a guaranteed right to buy certain Medigap policies for 63 days after your plan ends. See Medicare plans ending in Oregon in 2027.
- Medigap rules. We found no change to Oregon's Medigap rules for 2027. The birthday rule still lets current policyholders switch to a plan with the same or fewer benefits, without health questions, from 30 days before to 30 days after their birthday (OAR 836-052-0143, as amended effective January 1, 2023). A 2025 bill for a yearly Medigap open enrollment window (SB 1181) did not pass.
- Medicare Savings Programs. ODHS updates the dollar income limits each March. Oregon has no asset test for QMB, SMB or the SMF benefit. See Medicare Savings Programs in Oregon.
Reading your Annual Notice of Change
If you have a Medicare Advantage or Part D plan, the plan sends an Annual Notice of Change (ANOC) by September 30. Check these sections for 2027:
- Premium: what you will pay each month in 2027.
- Deductibles and copays: doctor visits, specialists, hospital stays and drugs.
- Drug list (formulary): whether each drug you take is still covered, on which tier, and whether it now needs prior authorization.
- Provider and pharmacy network: whether your doctors, hospital and pharmacy are still in network.
- Out-of-pocket limit: whether it changed.
- Extra benefits: Medicare Advantage plans may offer extra benefits such as dental, vision, hearing or fitness. Extra benefits vary by plan and county, may have limits and costs, and not every plan offers them. Check a plan's Summary of Benefits or Evidence of Coverage.
Your 2027 checklist
- Read your ANOC. Or your non-renewal letter, if your plan is ending.
- Check your doctors and drugs. Confirm they are covered the way you expect in 2027.
- Compare plans before December 7, 2026. Changes made during Open Enrollment start January 1, 2027. You can compare plans by ZIP code on PlanMatch or Medicare.gov, or you can request a call from a licensed insurance agent to review plans from the companies they work with.
- Check IRMAA. If your income dropped because you retired or stopped working, ask Social Security to use a newer year with Form SSA-44.
- Know your next window. If you are in a Medicare Advantage plan, you can make one change from January 1 to March 31, 2027. See the Medicare Advantage Open Enrollment Period guide.
