Oklahoma City residents shopping for 2027 Medicare Advantage coverage have a full slate to sort through this fall. According to the CMS Medicare Advantage Landscape Source File for plan year 2027, eight carriers are offering Medicare Advantage plans in Oklahoma County, where Oklahoma City sits. Every plan on next year's local roster includes prescription drug coverage.

This article walks through what's available, carrier by carrier, and points you to the full plan-by-plan table below. It does not compare plan costs or benefits — those live on the Medicare Plan Finder at medicare.gov and in each plan's own documents.

How the 2027 lineup looks in Oklahoma County

Oklahoma City is in Oklahoma County, and Medicare Advantage plan availability is set county by county. For 2027, the county has 52 Medicare Advantage plans on offer. CMS also reports zero stand-alone Part D plans listed for the area in this data file, which reflects how the local drug coverage picture is bundled into Medicare Advantage. Every Medicare Advantage plan on the local list next year comes with prescription drug coverage built in (often called MA-PD).

The county's population age 65 and older is roughly 116,513, giving carriers a sizable market to serve.

The nine carriers offering plans

Eight carriers are competing in Oklahoma County for 2027. In alphabetical order:

• Aetna (CVS Health) — 4 plans (HMO, PPO; 1 Special Needs Plan)
• American Health Advantage of Oklahoma — 1 plan (HMO; 1 Special Needs Plan)
• Blue Cross Blue Shield (HCSC) — 6 plans (HMO, PPO; 1 Special Needs Plan)
• Centene (WellCare) — 3 plans (PPO; 1 Special Needs Plan)
• CommunityCare Senior Health Plan (HMO) — 4 plans (HMO)
• Devoted Health — 5 plans (PPO; 3 Special Needs Plans)

• Humana — 18 plans (HMO, PFFS, PPO; 7 Special Needs Plans)
• UnitedHealthcare — 12 plans (HMO-POS, PPO; 5 Special Needs Plans)

The full plan-by-plan roster — including each plan's type and whether it includes drug coverage — is in the table below. A few examples of how naming conventions look across carriers: Aetna's local slate includes plans like Aetna Medicare Signature (HMO) and Aetna Medicare Eagle (PPO); Blue Cross offerings include Blue Cross Medicare Advantage Basic (HMO) and Blue Cross Medicare Advantage Optimum (PPO); CommunityCare's plans use the Senior Health Plan brand; Humana ranges from Humana Gold Plus HMOs to HumanaChoice PPOs and a Humana Gold Choice PFFS; and UnitedHealthcare markets AARP-branded plans and UHC Dual Complete plans.

Plan types you'll see on the list

Medicare Advantage plans come in a few flavors, and Oklahoma County's roster hits most of them:

• HMO (Health Maintenance Organization) — 18 plans. You usually pick a primary care doctor and stay in-network.
• HMO-POS (Point of Service) — 7 plans. An HMO with some out-of-network flexibility.
• PPO (Preferred Provider Organization) — 34 plans. Broader out-of-network access, typically at higher cost.
• PFFS (Private Fee-for-Service) — 1 plan. Providers decide whether to accept the plan's terms.

Of the 60 plans, 23 are Special Needs Plans (SNPs). SNPs are limited to people who meet the plan's eligibility rules — for example, D-SNPs (dual eligibility for Medicare and Medicaid), C-SNPs (chronic conditions like diabetes or heart disease) or I-SNPs (institutional, such as nursing home residents).

Drug coverage: what to know for 2027

All 60 Medicare Advantage plans in Oklahoma County include Part D drug coverage. If you enroll in one of these plans, your prescription benefit is part of the same package.

Program-level Part D rules that apply in 2027:

• The Part D out-of-pocket cap is $2,100 for the year. Once you hit it, you pay $0 for covered drugs the rest of the year.
• The maximum Part D deductible is $615.
• The old "donut hole" coverage gap has been eliminated as of 2025 — Part D now has three phases (deductible, initial coverage, catastrophic).
• The Medicare Prescription Payment Plan lets you spread your drug costs across the year in monthly payments, at no extra charge.
• IRMAA surcharges for higher-income enrollees kick in above $109,000 in income for single filers in 2026.

Key dates for enrollment

Two windows matter most:

• Annual Enrollment Period (AEP): Oct. 15 – Dec. 7. You can join, switch or drop a Medicare Advantage or Part D plan. Changes take effect Jan. 1.
• Medicare Advantage Open Enrollment Period: Jan. 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance to switch to another Medicare Advantage plan or return to Original Medicare.

Special Enrollment Periods may also apply if you move, lose other coverage, or qualify for Medicaid or Extra Help.
