Got a Medicare plan non-renewal letter in Tulsa? Your options for 2027

For 2027, Tulsa is looking at 55 Medicare Advantage plans: 7 new, 14 gone since 2026, and 20 still here but changed on premium, deductible, plan type or name, 5 of them under a new name. Below, how the lineup shifted in Tulsa County and what to compare, with no plan ranked or recommended.

TULSA — If you open your mailbox this fall and find a letter saying your Medicare Advantage plan will not be offered in 2027, you are not alone, and you are not stuck. According to CMS's 2027 Medicare Advantage Landscape file, 14 Advantage plans sold in Tulsa County this year are not returning next year. Members of those plans have extra time to choose what comes next — and a clear fallback if they do nothing.

Why this matters right now

Tulsa is in Tulsa County, where CMS lists 62 Medicare Advantage plans from 9 carriers for 2026 and 55 plans from 8 carriers for 2027. The gap between those two numbers is the story for a specific group of Tulsans: people whose current plan is one of the 14 that will not be sold here next year.

The Annual Enrollment Period runs October 15 – December 7, 2026, and any choice you make in that window starts January 1, 2027. If your plan is ending, you have more time than that — but it helps to decide early, while help lines are less crowded.

How you'll know: the non-renewal letter

Medicare requires a carrier that is discontinuing a plan to mail current members a non-renewal notice (sometimes called a plan termination letter) by early October. The letter will:

• Say the plan will not be offered in 2027.
• Explain that your coverage ends December 31, 2026.
• Describe your right to pick a new plan, and the Special Enrollment Period that comes with a non-renewal.

If you think you got one but aren't sure, call the member services number on your current ID card and ask directly: "Is my plan being offered in Tulsa County in 2027?"

The Tulsa County plans that are not returning for 2027

These 14 plans, listed in CMS's 2026 Landscape file for Tulsa County, are not in the 2027 file. They are grouped alphabetically by carrier:

• Aetna (CVS Health): Aetna Medicare Signature (PPO)
• Blue Cross Blue Shield (HCSC): Blue Cross Medicare Advantage Balance (PPO); Blue Cross Medicare Advantage Basic (HMO); Blue Cross Medicare Advantage Classic (PPO); Blue Cross Medicare Advantage Dental Premier (PPO); Blue Cross Medicare Advantage Dual Care Plus (HMO D-SNP); Blue Cross Medicare Advantage Health Choice (PPO); Blue Cross Medicare Advantage Optimum (PPO); Blue Cross Medicare Advantage Protect (PPO)
• Centene (WellCare): Wellcare Dual Access Open (PPO D-SNP); Wellcare Patriot Giveback Open (PPO); Wellcare Simple Open (PPO)
• Humana: HumanaChoice SNP-DE H5216-469 (PPO D-SNP)
• UnitedHealthcare: UHC Dual Complete OK-S002 (HMO-POS D-SNP)

If your plan is not on this list, it is expected to be offered again in 2027 — read the Annual Notice of Change (ANOC) your carrier mailed in September to see what is different. CMS also shows 7 new plans and 5 renamed plans in Tulsa County for 2027; the ANOC spells out any name change for your plan.

What happens if you do nothing

If your plan is on the non-renewal list and you make no choice by December 31, 2026, your Medicare Advantage coverage simply ends. On January 1, 2027, you are automatically back on Original Medicare — Part A (hospital) and Part B (medical) — administered by the federal government.

Two things to know about that:

• Original Medicare does not include prescription drug coverage. Without a stand-alone Part D plan, you could face a late enrollment penalty later and have no help paying for most prescriptions in the meantime.
• Original Medicare does not cap your out-of-pocket costs the way an Advantage plan does. Many people pair it with a Medicare Supplement (Medigap) policy to limit what they pay.

Doing nothing is a valid choice — but it is a choice, so make it on purpose.

Your Special Enrollment Period and your choices

Because your plan is leaving the market, Medicare gives you a Special Enrollment Period (SEP) that runs from December 8, 2026 through the end of February 2027. In that window you can:

1. Pick a different Medicare Advantage plan offered in Tulsa County for 2027. Your coverage starts the first of the month after you enroll. 2. Stay on Original Medicare and add a stand-alone Part D prescription drug plan. 3. Add a Medicare Supplement (Medigap) policy to Original Medicare. Losing coverage because your plan is non-renewed generally creates a guaranteed-issue right to buy certain Medigap policies without medical underwriting. The specific plans and timing are set by state rules — confirm with the Oklahoma Insurance Department before you apply.

The table below lists every Medicare Advantage plan offered in Tulsa County for 2026, including the 14 that are ending. Use it as a reference, then compare your real options at medicare.gov/plan-compare, where you can enter your prescriptions and preferred doctors.

A few 2027 program numbers to keep in mind

As you compare drug coverage for next year, two confirmed figures from CMS are useful:

• The Part D out-of-pocket cap rises to $2,400 in 2027 (it is $2,100 in 2026).
• The Part D maximum deductible rises to $700 in 2027 (it is $615 in 2026).

The 2027 Part B standard premium, Part B deductible and IRMAA income brackets have not been announced yet; CMS usually publishes those figures in the fall.
