Medicare Advantage

Got a letter about your Tulsa Advantage plan?

For 2027, Tulsa County has 50 Medicare Advantage plans from 8 carriers: 7 new, 14 gone since 2026, and 15 continuing plans with at least one change in their terms, 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.

Medicare AdvantageTulsa, OK

TULSA, Okla. — If you have a Medicare Advantage plan in Tulsa, the mail you get this fall is worth opening carefully. For plan year 2027, 14 Medicare Advantage plans sold in Tulsa County will not be offered again, 7 new plans are joining the market, and 5 more have been renamed, according to a comparison of the CMS Medicare Advantage Landscape Source Files for 2026 and 2027. Two carriers — Blue Cross Blue Shield (HCSC) and Centene (WellCare) — will not offer Medicare Advantage plans in the county next year, and one carrier, Native Advantage, is entering.

Tulsa is in Tulsa County, and Medicare plan availability is set at the county level, so these changes apply to anyone whose plan is offered there.

Plans leaving Tulsa County after 2026

If you are enrolled in any of the plans below, your coverage will end December 31, 2026, and you need to pick something else. The plans not returning in Tulsa County include every Blue Cross Blue Shield (HCSC) and Centene (WellCare) Medicare Advantage plan in the county, along with others:

• Aetna Medicare Signature (PPO)
• 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)
• Wellcare Dual Access Open (PPO D-SNP)
• Wellcare Patriot Giveback Open (PPO)
• Wellcare Simple Open (PPO)
• HumanaChoice SNP-DE H5216-469 (PPO D-SNP)
• UHC Dual Complete OK-S002 (HMO-POS D-SNP)

If your plan is on this list, watch for a non-renewal notice from your carrier. That letter is important — it triggers a Special Enrollment Period that runs through the end of February, giving you extra time to pick a new Medicare Advantage plan or move back to Original Medicare with a stand-alone Part D plan.

New plans for 2027

Seven Medicare Advantage plans are new to Tulsa County for 2027, including the first plan from a carrier that is new to the county, Native Advantage:

• Aetna Medicare Dual Extra Care (HMO D-SNP)
• Aetna Medicare Signature (PPO)
• Aetna Medicare Signature Care (HMO)
• DEVOTED C-SNP CHOICE GIVEBACK EXTRAS 012 OK (PPO C-SNP)
• DEVOTED CHOICE GIVEBACK EXTRAS 014 OK (PPO)
• Native Advantage (HMO)
• UHC Dual Complete OK-S002 (HMO-POS D-SNP)

You may notice a couple of names that look familiar — some carriers have retired a 2026 plan and introduced a new 2027 plan with a similar name. Those are separate contracts. If you were on the 2026 version, you will still need to actively choose your 2027 coverage.

Renamed plans (same plan, new label)

Five plans return in 2027 with a new name. If your plan is on this list, you generally do not have to do anything to stay enrolled, but the name on your card or paperwork may look different:

• DEVOTED C-SNP CHOICE ENHANCED 010 OK (PPO C-SNP) — was DEVOTED C-SNP CHOICE PREMIUM 010 OK
• Humana Essentials Plus Giveback (PPO) — was HumanaChoice Giveback H7617-056
• Humana Total Complete (HMO) — was Humana Gold Plus H6622-033
• Humana Value Choice (PPO) — was Humana Full Access H7617-053
• UHC Dual Advantage OK-V1 (HMO-POS D-SNP) — was UHC Dual Complete OK-V001

Plans that are changing — read your ANOC

Beyond the leaves, adds and renames, 15 continuing plans have at least one difference in CMS's 2027 file compared with 2026. The Landscape file does not tell you what changed for your specific situation. That is what the Annual Notice of Change (ANOC) is for. Your carrier is required to send it before the Annual Enrollment Period, and it spells out exactly what is different next year.

Read it side by side with your current plan documents, and pay attention to:

• Your monthly premium and any deductible
• Your regular doctors and hospitals (still in-network?)
• Your prescriptions (still on the drug list, still the same tier?)
• Extra benefits you actually use

What to do — and when

The Annual Enrollment Period runs October 15 through December 7. Any plan choice you make in that window takes effect January 1, 2027. If your plan is on the "leaving" list above, you also have a Special Enrollment Period through the end of February to switch — but do not wait, because your old plan will already have ended.

There is also the Medicare Advantage Open Enrollment Period, January 1 through March 31, which lets someone already in a Medicare Advantage plan make one change.

A few program-level facts to keep in mind while you compare drug coverage for 2026 and 2027:

• The Part D out-of-pocket cap is $2,100 for 2026.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") was eliminated in 2025 — Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly amounts, if you opt in.
• IRMAA surcharges start above $109,000 in income (single filer) for 2026.
