How many Medicare Advantage plans are offered in Oklahoma for 2027, and what should members do about the changes?

Oklahoma has 81 Medicare Advantage plans for 2027, compared with 82 in 2026, offered across all 77 counties. Within that total, 14 plans are not returning anywhere in the state, 13 plans are new, and 24 continuing plans are changing a premium, a drug deductible, a plan type or a plan name.

Several carriers will not offer a Medicare Advantage plan in Oklahoma for 2027: Blue Cross and Blue Shield of IL, NM, OK, TX; Blue Cross and Blue Shield of OK, TX; Blue Cross and Blue Shield of Oklahoma; and Wellcare. One carrier is new to Oklahoma's Medicare Advantage market for 2027: Native Advantage.

If you are already in a Medicare Advantage or Part D plan, two letters matter. The Annual Notice of Change arrives in September and spells out what will be different in 2027 — the premium, the drug deductible, the drug list, the pharmacy network and the doctor network can all shift. If your plan is leaving, you will receive a separate non-renewal letter. That letter opens a Special Enrollment Period that runs through the end of February 2027 to pick a new Medicare Advantage plan or return to Original Medicare and add a stand-alone Part D plan. You do not have to wait for December 7 to act, and you are not stuck if the letter arrives late.

Because Medicare Advantage plans are sold county by county, a plan counted in the statewide total may or may not be offered where you live. The Medicare Plan Finder at medicare.gov will show what is actually available at your ZIP code.

Which Oklahoma counties have the most Medicare Advantage change for 2027?

Five Oklahoma counties stand out for 2027 turnover. Creek County has 19 plans leaving and 13 changing. Lincoln County has 17 leaving and 14 changing. Canadian County has 13 leaving and 16 changing. Logan County has 13 leaving and 16 changing. Tulsa County has 14 leaving and 15 changing.

If you live in one of those counties, read the Annual Notice of Change carefully. "Changing" can mean a different plan name, a different plan type (HMO versus PPO), a new premium or a new drug deductible — any of which can affect how you use the plan next year, even if your ID card still looks familiar.

How many stand-alone Part D plans are offered in Oklahoma for 2027?

Oklahoma has 9 stand-alone Part D prescription drug plans for 2027, down from 11 in 2026, offered by 4 insurers. These are the plans used with Original Medicare (and with most Medigap policies) to cover prescriptions.

Two national rules apply to every Part D plan in Oklahoma. The annual out-of-pocket cap on covered drugs is $2,400 in 2027, up from $2,100 in 2026. The highest deductible any Part D plan may charge in 2027 is $700; plans may charge less, or zero, but not more. The Part D base beneficiary premium used in the late-enrollment penalty calculation is $41.33 for 2027; individual plan premiums are set plan by plan.

What Medigap options are listed for Oklahoma on Medicare.gov for 2027?

Medicare.gov lists 27 Medigap (Medicare Supplement) insurers for a ZIP code in Oklahoma. Medigap works only with Original Medicare, not Medicare Advantage, and the lettered plans (Plan G, Plan N and so on) are standardized, meaning the same letter covers the same things from any insurer. Pricing and underwriting rules differ, and the strongest consumer protections apply during your one-time Medigap Open Enrollment Period when you first have Part B. Compare specific policies on medicare.gov or by calling 1-800-MEDICARE.

What are the national Medicare numbers for 2027, and what did Social Security announce?

For 2027, three national Medicare numbers are set: the Part D out-of-pocket cap is $2,400, the maximum Part D deductible is $700, and the Part D base beneficiary premium is $41.33. Annual Enrollment 2027 runs October 15 – December 7, 2026, and choices take effect January 1, 2027.

The Social Security Administration announced on October 14, 2026 a 3.6 percent cost-of-living adjustment (COLA) for benefits payable beginning January 2027.

The 2027 Part B standard premium and deductible have not been announced yet; CMS typically releases those figures in the fall, usually November. The 2027 IRMAA income-related surcharges are published alongside the Part B figures and have not been announced yet either. Watch medicare.gov and ssa.gov for the official release.
