Colorado Medicare Advantage Plans for Chronic Conditions in 2027: 12 C-SNPs

DENVER — Coloradans living with a serious ongoing health condition will have 12 Chronic Condition Special Needs Plans (C-SNPs) to consider for 2027, out of 104 Medicare Advantage plans offered statewide, according to the CMS Medicare Advantage Landscape Source Files for the coming plan year. These plans are a specialized slice of Medicare Advantage designed around a qualifying chronic illness, and availability varies county by county.

What is a C-SNP in Colorado and who qualifies for one in 2027?

A C-SNP is a type of Medicare Advantage plan built for people with a specific, qualifying chronic condition that is verified by a treating provider. To enroll, you must have Medicare Parts A and B, live in the plan's service area in Colorado, and have the condition the plan is designed to serve.

CMS defines the list of qualifying conditions nationally — examples include diabetes, chronic heart failure, and chronic lung disorders — and each C-SNP targets one condition or a related group. After you apply, the plan contacts your provider to confirm the diagnosis. If the condition cannot be verified, you are not enrolled in that C-SNP. Benefits, drug coverage, provider networks, and cost-sharing are set by each plan and are available on the Medicare Plan Finder at medicare.gov or in the plan's Evidence of Coverage.

How many C-SNPs are offered statewide in Colorado for 2027, and which carriers offer them?

Colorado's 2027 landscape includes 12 C-SNPs statewide, offered by four carriers: Aetna (CVS Health) with 1 plan, Devoted Health with 7 plans, Elevance Health (Anthem) with 1 plan, and UnitedHealthcare with 3 plans. For context, Colorado also has 23 Dual Eligible Special Needs Plans (D-SNPs) and 4 Institutional Special Needs Plans (I-SNPs) in the same CMS file.

The full plan names, parent organizations, and the number of counties each plan is offered in are shown in the tables on this page. Several of the Devoted Health plans are renamed versions of 2026 plans (the "PREMIUM" plans are now "ENHANCED"), and new entries for 2027 include the Aetna Medicare Chronic Care plan, the Anthem Chronic Care plan, and three Devoted "GIVEBACK EXTRAS" plans. Being new, renamed, or offered in more counties does not make a plan better or worse — it is just what the CMS file shows.

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

Under CMS rules for this explainer, we can only name a condition when the plan's own name states it — and none of Colorado's 12 C-SNP names for 2027 spell out a specific condition. Names such as "Aetna Medicare Chronic Care," "Anthem Chronic Care," "UHC Complete Care CO-19," and the "DEVOTED C-SNP" plans refer to chronic care generally without naming diabetes, heart conditions, lung conditions, or any other diagnosis.

That does not mean the plans serve every condition. Each C-SNP is tied to one qualifying condition (or a defined group) in its CMS contract. To find out which condition a specific Colorado plan serves, check the plan's listing on the Medicare Plan Finder at medicare.gov, call 1-800-MEDICARE, or read the plan's Evidence of Coverage.

Is there a Special Enrollment Period for Coloradans with a qualifying chronic condition in 2027?

Yes. People with a CMS-qualifying chronic condition can use a Special Enrollment Period (SEP) to join a C-SNP that serves that condition, outside the regular Annual Enrollment Period. This SEP is available once your condition is verified and you meet the plan's service-area and Medicare requirements.

The Annual Enrollment Period itself runs October 15 through December 7, 2026, and any choice made during that window takes effect January 1, 2027. If you qualify for the chronic-condition SEP, you are not limited to that fall window — but you still can only enroll in a plan whose service area covers your Colorado county. Details on enrollment periods are published by CMS at medicare.gov.

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

Availability is county by county, so a plan listed statewide may not be offered where you live. The fastest check is the Medicare Plan Finder at medicare.gov: enter your ZIP code, and the tool shows every Medicare Advantage plan — including C-SNPs — available in your county for 2027.

The CMS Landscape Source File is the underlying data. Among Colorado's 12 C-SNPs, county footprints range widely — for example, UHC Complete Care CO-2P is listed in 1 county, while DEVOTED C-SNP PLUS 013 CO is listed in 39. The county counts for every plan appear in the tables on this page. When you compare plans, look at the service area first, then confirm the condition served, the drug list, provider network, and cost-sharing in the plan's own documents.

Where can Coloradans get free help choosing a C-SNP for 2027?

Two free, non-sales resources are available to every Colorado Medicare beneficiary. The Medicare Plan Finder at medicare.gov lets you compare 2027 plans side by side using your ZIP code, prescriptions, and preferred pharmacies. And 1-800-MEDICARE (TTY 1-877-486-2048) is staffed 24 hours a day, 7 days a week with representatives who can walk through plan options, enrollment periods, and the chronic-condition SEP.

Neither resource sells plans or earns a commission, and both draw on the same CMS data behind this article.
