Aetna's 2027 Medicare Advantage plans in Tulsa: how to vet each one before Dec. 7

Tulsa, Okla. — Aetna's Medicare Advantage lineup in Tulsa County is shifting for 2027, with three new plans joining the roster, one plan not returning, and a mix of HMO and PPO options — including two Dual Special Needs Plans — all carrying prescription drug coverage. If you already have an Aetna plan, nothing happens automatically beyond the changes spelled out in your Annual Notice of Change (ANOC); if you want to switch, the window to do it for a Jan. 1, 2027 start is Oct. 15 through Dec. 7, 2026.

MyMedicarePlans.org is an independent consumer news site and is not Aetna. Aetna is one of eight carriers offering Medicare Advantage plans in Tulsa County next year, and there are 55 Medicare Advantage plans in the county for 2027 all told.

How many Aetna Medicare Advantage plans are offered in Tulsa for 2027?

In Tulsa County, Aetna (listed by CMS as Aetna (CVS Health)) is offering 6 Medicare Advantage plans for 2027. By plan type that breaks down to 2 HMO plans and 4 PPO plans, and all 6 include Part D prescription drug coverage.

Of those 6, two are Dual Special Needs Plans (D-SNPs) — one HMO D-SNP and one PPO D-SNP — designed for people who have both Medicare and full Medicaid. Aetna is not offering a Chronic Condition SNP (C-SNP) or an Institutional SNP (I-SNP) in Tulsa County next year.

Tulsa is in Tulsa County, and Medicare Advantage availability is set at the county level, so the same lineup applies throughout the county.

What is new, renamed or not returning from Aetna in Tulsa County for 2027?

Three of Aetna's six Tulsa County plans are new for 2027, and one plan the carrier offered in 2026 is not returning. The table on this page lists every Aetna plan by name and type for next year.

The new-for-2027 plans are Aetna Medicare Dual Extra Care (HMO D-SNP), Aetna Medicare Signature (PPO) and Aetna Medicare Signature Care (HMO). The returning plans are Aetna Medicare Dual Care (PPO D-SNP), Aetna Medicare Eagle (PPO) and Aetna Medicare Value Plus (PPO).

If you are already in an Aetna plan, read the Annual Notice of Change the carrier mailed in September. It will say whether your plan continues, what is changing, and — if your plan is the one not returning — your options.

How do I check an Aetna plan against my doctors and prescriptions before Dec. 7?

Use the official Medicare Plan Finder at medicare.gov, or call 1-800-MEDICARE (TTY 1-877-486-2048), 24 hours a day, 7 days a week. Both will show the plans available at your ZIP code and let you enter your prescriptions to see how each plan's drug list treats them.

A short checklist that works for any plan:

• Enter your ZIP code and your drugs on Medicare.gov to see the plan's formulary, tier placement and pharmacy options.
• Confirm your doctors, hospitals and specialists are in-network by checking the plan's own provider directory on the carrier's website or by calling the plan directly.
• If you take a specialty medication, ask whether the plan uses prior authorization or step therapy for it.
• For the full rules on a plan — benefits, cost-sharing, service area — read its Evidence of Coverage.

Networks, drug lists and costs can change year to year even if the plan name stays the same, so verifying for 2027 matters even if you have been on the same plan for years.

What are the key Medicare dates and 2027 figures to know in Tulsa?

The Annual Enrollment Period runs Oct. 15 through Dec. 7, 2026. Any change made in that window takes effect Jan. 1, 2027. If you do nothing, your current plan renews for 2027 as long as it is still offered, with the changes described in its ANOC.

A separate Medicare Advantage Open Enrollment Period runs Jan. 1 through March 31, 2027. During that window, someone already in a Medicare Advantage plan can switch to a different MA plan one time or go back to Original Medicare.

CMS has confirmed a few program-level Part D figures for 2027:

• Part D out-of-pocket cap: $2,400 in 2027 (up from $2,100 in 2026).
• Part D maximum deductible: $700 in 2027 (up from $615 in 2026).
• Part D national base beneficiary premium for 2027: $41.33 (a formula input, not what any specific plan charges).

The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, have not been published yet; CMS typically releases them later in the fall.

What if my Aetna plan is the one not returning in 2027?

If your current Aetna plan is not offered for 2027, Aetna will tell you in writing, and you have a Special Enrollment Period to choose another plan. You can pick a different Medicare Advantage plan from any carrier in Tulsa County or return to Original Medicare and add a stand-alone Part D drug plan.

The clearest way to compare your options is Medicare.gov's Plan Finder with your drugs and preferred pharmacies entered, or a call to 1-800-MEDICARE. Remember that there are 55 Medicare Advantage plans in Tulsa County for 2027 across all 8 carriers, so there is room to compare before choosing.
