What CMS counts for Oklahoma in 2027
Every fall, the Centers for Medicare & Medicaid Services (CMS) publishes a Landscape file that lists each Medicare Advantage and Part D plan by county for the coming year. Here is what it shows for Oklahoma for 2027:
| Plan type (2027) | Oklahoma count |
|---|---|
| Medicare Advantage plans open to everyone | 50 |
| Special needs plans (SNPs) | 27 |
| Companies offering Medicare Advantage | 9 |
| Standalone Part D drug plans | 9 |
These are counts only. They don't tell you what any plan costs or covers. For that, read each plan's Summary of Benefits or Evidence of Coverage.
The number depends on your county
You can join only a plan that serves the county where you live. In Oklahoma, the choice is widest in the metro areas and narrowest in the northwest:
| County | Medicare Advantage plans open to everyone, 2027 |
|---|---|
| Oklahoma County | 35 |
| Tulsa County | 32 |
| Cleveland County | 33 |
| Comanche County | 19 |
| Woodward County | 4 |
| Beaver, Cimarron, Ellis, Harmon, Harper, Roger Mills and Texas counties | 0 |
In those seven counties, only special needs plans are offered for 2027. See is Medicare Advantage available in every Oklahoma county and your county page for the local count.
What to do with the number
- Find your county's plans. Use Medicare Plan Finder or see plans for your ZIP code.
- Check your doctors and drugs. Narrow the list to plans whose network includes your doctors and hospitals and whose drug list includes your medicines.
- Decide during open enrollment. Changes made between October 15 and December 7, 2026 start January 1, 2027.
To compare plans from the companies they work with, you can request a call from a licensed insurance agent. Learn more in our guide to Medicare Advantage in Oklahoma, and see how to compare Medicare Advantage plans in Oklahoma.

Frequently asked questions
Why does the number of plans depend on my county?
Each Medicare Advantage plan chooses the counties it serves, and you must live in a plan's service area to join it. Plans tend to cover counties where they have contracts with doctors and hospitals, so the Oklahoma City and Tulsa areas have more choices than rural western counties.
Are special needs plans included in the count?
No. The 50 plans are the ones anyone with Medicare Part A and Part B in the plan's area can join. The 27 special needs plans are counted separately because they are only for people who also have SoonerCare, live in a nursing home or have certain chronic conditions.
How many standalone Part D plans are there in Oklahoma for 2027?
CMS lists 9 standalone Part D prescription drug plans in Oklahoma for 2027. Unlike Medicare Advantage, standalone drug plans are offered statewide, so every county has the same list.
Does a larger number of plans mean better coverage?
Not by itself. What matters is whether a plan includes your doctors, hospitals and medicines. A county with a few plans may still have one that fits you, and a county with many may have none that includes your doctor.
