Diagnosed With a Chronic Illness in Tulsa? Read This First

For 2027, Tulsa is looking at 55 Medicare Advantage plans: 7 new, 14 gone since 2026, and 20 still here but changed on premium, deductible, plan type or name, 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.

TULSA — As Medicare's Annual Enrollment Period opens for 2027 coverage, people in Tulsa County who live with a serious ongoing illness have a specific slice of the Medicare Advantage market to look at: Chronic Condition Special Needs Plans, or C-SNPs. For 2027, nine C-SNPs are being offered in the county, from four carriers, according to CMS's Medicare Advantage Landscape file.

These plans are different from a standard Medicare Advantage plan. You can only join a C-SNP if a doctor confirms you have one of the qualifying chronic conditions the plan is built to serve. That rule is the whole point of the plan type — and it also opens a Special Enrollment Period, so you are not stuck waiting for the fall window.

What a C-SNP actually is

A Chronic Condition Special Needs Plan is a type of Medicare Advantage plan. Like other Advantage plans, it replaces Original Medicare for your Part A and Part B coverage, and all nine of the C-SNPs in Tulsa County include Part D drug coverage.

What makes it a C-SNP is who is allowed in. CMS limits enrollment to people who have one of 15 approved chronic conditions — things like diabetes, chronic heart failure, cardiovascular disorders, chronic lung disorders, or end-stage renal disease. Each plan picks the condition (or group of conditions) it is built around, then shapes its drug list, provider network and care coordination around that illness.

Because every member shares a diagnosis, the plan can do things a general Medicare Advantage plan usually does not: assign a care coordinator, build in specialist access, and pay more attention to the medications that go with that condition. The specifics are different at every carrier, so the plan's Evidence of Coverage and formulary are the only places to confirm what any one plan does.

The 9 C-SNPs offered in Tulsa County for 2027

Tulsa is in Tulsa County, where CMS lists nine C-SNPs for 2027 from four carriers. In alphabetical order by carrier:

• Devoted Health (3): DEVOTED C-SNP CHOICE ENHANCED 010 OK (PPO C-SNP) — renamed from DEVOTED C-SNP CHOICE PREMIUM 010 OK; DEVOTED C-SNP CHOICE GIVEBACK EXTRAS 012 OK (PPO C-SNP) — new for 2027; DEVOTED C-SNP CHOICE PLUS 008 OK (PPO C-SNP).
• GlobalHealth (2): Generations Chronic Care (HMO C-SNP); Generations Chronic Care Savings (HMO C-SNP).
• Humana (3): Humana Gold Plus - Diabetes and Heart (HMO C-SNP); HumanaChoice - Diabetes and Heart (PPO C-SNP); HumanaChoice - Diabetes and Heart (PPO C-SNP).
• UnitedHealthcare (1): UHC Complete Care OK-9 (HMO-POS C-SNP).

The table on this page lists every plan with its type. For 2027, two Humana plans and one UnitedHealthcare plan name the conditions they serve right in the plan name; for the others, the plan documents are the only reliable source for which condition qualifies. To fit the broader picture: C-SNPs are 9 of the 55 Medicare Advantage plans available in Tulsa County for 2027, alongside 12 Dual-Eligible SNPs (D-SNPs) and 2 Institutional SNPs (I-SNPs).

How enrollment works — and the diagnosis requirement

To join a C-SNP, you need Medicare Part A and Part B, you need to live in the plan's service area, and a provider has to verify in writing that you have the qualifying chronic condition the plan serves. Plans usually send a short form your doctor's office signs and returns. If that verification does not come through in the window CMS allows, the enrollment is cancelled.

That diagnosis rule is also why C-SNPs come with their own Special Enrollment Period. If you are newly diagnosed with a qualifying chronic condition, you generally have a window to enroll in a matching C-SNP outside the regular fall enrollment dates — you do not have to wait for Oct. 15. If you later no longer have the qualifying condition, there are rules about staying on or leaving the plan; the plan will walk you through those.

Where this fits in the 2027 enrollment calendar

The Annual Enrollment Period runs Oct. 15 – Dec. 7, 2026, and any change you make takes effect Jan. 1, 2027. If you do nothing, your current plan renews for 2027 if the carrier is still offering it — with whatever changes are described in the Annual Notice of Change (ANOC) that arrived in September. In Tulsa County, 14 plans are not returning for 2027, 7 are new, and 5 have been renamed, so the ANOC is worth reading carefully this year.

A few program-level numbers to keep in mind as you compare drug coverage inside any C-SNP:

• Part D out-of-pocket cap: $2,100 in 2026, rising to $2,400 in 2027.
• Part D maximum deductible: $615 in 2026, rising to $700 in 2027.
• The 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 level monthly bills instead of paying at the pharmacy counter.

CMS has not yet announced the 2027 Part B standard premium and deductible or the 2027 IRMAA income brackets; those typically come out later in the fall.
