Anthem Medicare Advantage in Colorado for 2027: 3 Plans, County by County

DENVER — For the 2027 plan year, Anthem — which the Centers for Medicare & Medicaid Services groups under Elevance Health (Anthem) — is listed in Colorado with three Medicare Advantage plans, according to the CMS Medicare Advantage Landscape Source File. Each plan is offered county by county, so a plan listed at the statewide level may or may not appear on the shelf where a specific Coloradan lives. This article is published by an independent Medicare education site; it is not the government and not Anthem.

What is Anthem offering across Colorado for 2027?

Anthem is offering 3 Medicare Advantage plans statewide in Colorado for 2027: 2 HMO plans and 1 HMO-POS plan, per the CMS Landscape file. All 3 include prescription drug coverage.

Among those 3, there is 1 Dual-Eligible Special Needs Plan (D-SNP) for people who have both Medicare and Medicaid, and 1 Chronic Condition Special Needs Plan (C-SNP) for people with a qualifying chronic condition. Anthem lists no Institutional Special Needs Plans (I-SNPs) in Colorado for 2027. For context, 10 other carriers are offering Medicare Advantage plans in Colorado for 2027, and all carriers combined account for 104 plans statewide. The full plan-by-plan details appear in the tables on this page rather than being repeated in prose.

Which Anthem plans in Colorado have the widest county reach for 2027?

In Colorado for 2027, Anthem Dual Advantage (HMO D-SNP) has the widest county reach among Anthem's plans, listed in 15 counties, followed by Anthem Medicare Advantage (HMO-POS) in 11 counties and Anthem Chronic Care (HMO-POS C-SNP) in 4 counties, according to the CMS Landscape file.

These counts are statewide totals. Each plan is sold on a county-by-county basis, so a plan that appears in 15 counties still may not be offered in the county where any given reader lives. The accompanying table on this page shows the plan names, types and county counts side by side; it is the quickest way to see which of the three plans even reaches your part of the state before you look at any plan details.

What is new or not returning from Anthem in Colorado for 2027?

Anthem has 1 new Medicare Advantage plan in Colorado for 2027 and 0 plans leaving the state, based on a year-over-year comparison of the CMS Landscape Source Files for CY2026 and CY2027.

The new plan is Anthem Chronic Care (HMO-POS C-SNP), a Chronic Condition Special Needs Plan listed in 4 Colorado counties. In addition, Anthem Medicare Advantage was renamed from an HMO to an HMO-POS for 2027 — the plan continues, but its product type label changed. Because no Anthem plans are listed as non-renewing in Colorado for 2027, current Anthem members in the state should not see a plan-wide exit notice from this carrier, though individual benefit, cost and network details for any plan can still change from year to year and are set out only in each plan's Annual Notice of Change and Evidence of Coverage.

How do I check whether an Anthem plan is offered in my Colorado county and covers my doctors and prescriptions?

To check whether a specific Anthem plan is offered in your Colorado county for 2027 and whether it covers your doctors and prescriptions, use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, 7 days a week.

Enter your ZIP code and county, then compare the plans that appear on your local shelf. For each plan you are considering, the specifics — monthly premium, deductibles, cost sharing, extra benefits, pharmacy network, provider network and star rating — come from the plan's own documents, not from a statewide summary. You can confirm doctors and hospitals through the plan's provider directory and prescription coverage through its formulary, both available from the carrier directly, and you can request an Evidence of Coverage to see the full rules before you decide.

What should Coloradans do before December 7, 2026?

Before December 7, 2026, Coloradans who want to join, switch or drop a Medicare Advantage plan for 2027 should make that election during the Annual Enrollment Period, which runs October 15 through December 7, 2026. A choice made during that window takes effect January 1, 2027.

A practical sequence: read the Annual Notice of Change your current plan mails in the fall; list your doctors, hospitals and prescriptions; look up your county on the Medicare Plan Finder; and compare the 2027 plans available where you live, including, if you wish, the Anthem plans listed in the table on this page. There is no need to rush — the December 7, 2026 date is fixed, and the same tools are available throughout the window.

Where can Coloradans get free help comparing 2027 Medicare plans?

Coloradans can get free, around-the-clock help from Medicare itself at 1-800-MEDICARE (TTY 1-877-486-2048) and on medicare.gov, which hosts the official Medicare Plan Finder.

Those two sources let you see every Medicare Advantage plan available in your county for 2027, including the Anthem plans discussed here and plans from the 10 other carriers in Colorado. They are free, they are not tied to any carrier, and they are the same tools used to produce the counts in this article.
