Oklahoma Medicare Advantage Plans for Chronic Conditions in 2027: 13 C-SNPs

OKLAHOMA — For the 2027 plan year, Oklahomans living with certain long-term health conditions have a specific slice of Medicare Advantage to look at: the Chronic Condition Special Needs Plan, or C-SNP. According to the CMS Medicare Advantage Landscape Source File for 2027, 13 of the 81 Medicare Advantage plans available somewhere in the state are C-SNPs. Four carriers offer them.

C-SNPs are not for everyone. They are built around a qualifying chronic condition that a provider has to verify. For the people they fit, they are a focused option worth understanding before the Annual Enrollment Period closes on December 7, 2026.

What is a C-SNP and who qualifies for one in Oklahoma?

A C-SNP is a type of Medicare Advantage plan limited to people with a specific severe or disabling chronic condition, such as diabetes or certain cardiovascular disorders. To enroll, a provider has to verify that you have the qualifying condition the plan is designed around.

Beyond that verification, the usual Medicare Advantage rules apply: you need to have Medicare Part A and Part B, and you need to live in the plan's service area. Most C-SNPs also include Part D prescription drug coverage built in. If your condition changes or your diagnosis cannot be verified, you may not be able to stay in the plan, which is why the condition check matters at the front end.

How many C-SNPs are offered in Oklahoma for 2027 and who offers them?

Oklahoma has 13 C-SNPs across the state for 2027, out of 81 Medicare Advantage plans total. Four carriers offer them: Devoted Health has 5 C-SNPs, GlobalHealth has 2, Humana has 3, and UnitedHealthcare has 3.

For context, the CMS Landscape file also shows 14 Dual Eligible Special Needs Plans (D-SNPs) and 2 Institutional Special Needs Plans (I-SNPs) available in the state, serving different populations. The full plan names, plan types, and county counts are shown in the tables on this page rather than repeated here. A plan counted statewide may or may not be offered in your specific county — several of these C-SNPs are offered in just a handful of counties, while others reach a few dozen.

Which chronic conditions are named in Oklahoma C-SNP plan names for 2027?

Only some of the 13 C-SNP names state the condition they serve. In Oklahoma for 2027, the Humana C-SNPs name their focus directly: Humana Gold Plus - Diabetes and Heart (HMO C-SNP) and HumanaChoice - Diabetes and Heart (PPO C-SNP) indicate they are built for people with diabetes and certain cardiovascular or heart conditions.

The other C-SNPs on the Oklahoma list — from Devoted Health (the DEVOTED C-SNP CHOICE ENHANCED, GIVEBACK EXTRAS, and PLUS plans), from GlobalHealth (Generations Chronic Care and Generations Chronic Care Savings), and from UnitedHealthcare (the UHC Complete Care OK plans) — do not spell the qualifying condition out in the plan name. For those, you have to look at the plan's own materials, or call the carrier or 1-800-MEDICARE, to confirm the exact qualifying condition.

Three C-SNPs on the 2027 list are new for next year: DEVOTED C-SNP CHOICE GIVEBACK EXTRAS 011 OK, DEVOTED C-SNP CHOICE GIVEBACK EXTRAS 012 OK, and UHC Complete Care OK-2P. Two others, the DEVOTED C-SNP CHOICE ENHANCED 009 OK and 010 OK plans, were renamed from the "Premium" versions offered in 2026.

Is there a Special Enrollment Period for people with a qualifying chronic condition in Oklahoma?

Yes. People who qualify for a C-SNP have a Special Enrollment Period (SEP) that lets them enroll in a C-SNP outside the regular Annual Enrollment Period, once the qualifying condition is verified. The SEP generally allows one enrollment into a C-SNP based on the chronic condition.

Everyone else uses the standard windows: the Annual Enrollment Period from October 15 to December 7, 2026, for coverage starting January 1, 2027, and the Medicare Advantage Open Enrollment Period from January 1 to March 31, 2027, for people already in a Medicare Advantage plan who want to switch once. Medicare.gov has the full rules on which periods apply in which situations.

How do I check whether an Oklahoma C-SNP is offered in my county for 2027?

Use the Medicare Plan Finder at medicare.gov and enter your ZIP code, or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, 7 days a week. The 13 C-SNPs listed statewide are each offered in a specific set of counties — some in only 1, others in more than 40 — so a plan on the statewide list may not appear in your ZIP code search.

The tables on this page show each plan's county count drawn from the CMS Landscape file, which is the official source for availability. For premiums, deductibles, copays, provider networks, drug lists, and star ratings, go to the Medicare Plan Finder, call 1-800-MEDICARE, or read the plan's Evidence of Coverage and provider and pharmacy directories directly. That is where the plan-specific numbers live.

Where can Oklahomans get free help comparing 2027 Medicare plans?

Two free federal resources are available to everyone with Medicare in Oklahoma. The Medicare Plan Finder at medicare.gov lets you compare Medicare Advantage, C-SNP, D-SNP, and stand-alone Part D plans side by side for your ZIP code, including the plan's own cost and coverage details. And 1-800-MEDICARE (TTY 1-877-486-2048) is staffed 24 hours a day, 7 days a week to answer questions and walk through enrollment.

If you want to confirm you have Medicare Part A and Part B, or check your Medicare number, the Social Security Administration handles enrollment in Original Medicare.
