Kaiser Permanente is offering 11 Medicare Advantage plans across Colorado for the 2027 plan year, based on the CMS Landscape Source Files for CY2027. All 11 plans include Part D prescription drug coverage.

Broken down by plan type, Kaiser Permanente's Colorado lineup is 6 HMO plans and 5 HMO-POS plans. Three of the 11 are Dual-eligible Special Needs Plans (D-SNPs), designed for people enrolled in both Medicare and Medicaid; Kaiser Permanente is not offering any Chronic Condition SNPs (C-SNPs) or Institutional SNPs (I-SNPs) in Colorado for 2027. For context, CMS lists 10 other Medicare Advantage carriers in Colorado for 2027, with all carriers combined offering 104 plans statewide. Plans are offered county by county, so a plan listed statewide may not be available in the county where you live.

Which Kaiser Permanente plans reach the most Colorado counties in 2027?

Several Kaiser Permanente plans are listed by CMS as available in 11 Colorado counties for 2027, which is the widest reach in the carrier's Colorado lineup. According to the CMS Landscape file, the plans at that 11-county reach include Kaiser Permanente Dual Complete (HMO D-SNP), Kaiser Permanente Dual Essential (HMO D-SNP), Kaiser Permanente Senior Advantage Bronze DM (HMO-POS), Kaiser Permanente Senior Advantage Core DM (HMO-POS), Kaiser Permanente Senior Advantage Gold (HMO-POS), and Kaiser Permanente Senior Advantage Silver DM (HMO-POS).

Others are more regional. Kaiser Permanente Senior Advantage Core South (HMO-POS) and Kaiser Permanente Senior Advantage Enhanced (HMO-POS) are each listed in 4 counties; Kaiser Permanente Senior Advantage Core North (HMO-POS) and Kaiser Permanente Senior Advantage Silver North (HMO-POS) are each listed in 2 counties; and Kaiser Permanente Dual Complete Pueblo (HMO D-SNP) is listed in 1 county. The full county-by-county breakdown appears in the tables on this page rather than being repeated here in prose.

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

For the 2027 plan year, Kaiser Permanente has 0 new Medicare Advantage plans in Colorado, and 3 of its 2026 plans are not returning, according to the CMS Landscape Source Files comparing CY2026 and CY2027.

Four plans are being renamed rather than newly launched. The CMS data shows Kaiser Permanente Senior Advantage Core DM, Core North, and Core South each moving from an HMO label to an HMO-POS label in their plan names for 2027. If you are currently enrolled in a Kaiser Permanente plan, you should receive an Annual Notice of Change (ANOC) from the plan explaining what — if anything — is changing for your specific coverage in 2027. If your plan is one of the three not returning, the ANOC or a separate non-renewal notice will explain your options.

How do I check whether a Kaiser Permanente plan is offered in my Colorado county and covers my doctors and prescriptions?

To check whether a specific Kaiser Permanente plan is offered in your Colorado county for 2027, use the Medicare Plan Finder at medicare.gov and enter your ZIP code, or call 1-800-MEDICARE (1-800-633-4227), available 24 hours a day, 7 days a week. Because Medicare Advantage plans are sold county by county, a plan listed in Kaiser Permanente's statewide 2027 lineup may or may not be offered where you live.

For doctors, hospitals, and prescriptions, go directly to the plan's own materials. The Evidence of Coverage, Summary of Benefits, provider directory, and drug formulary from Kaiser Permanente are the authoritative sources for what a specific plan covers, which providers are in network, and how a given prescription is handled. The Plan Finder at medicare.gov also lets you enter your medications and preferred pharmacies to see plan-by-plan details side by side.

What should Colorado Medicare shoppers do before December 7, 2026?

Before December 7, 2026, Colorado Medicare shoppers should review their current coverage against their 2027 options during the Annual Enrollment Period, which runs October 15 – December 7, 2026. A choice made in that window takes effect January 1, 2027.

A practical sequence: read the ANOC from your current plan, make a list of your doctors and prescriptions, and then compare plans on medicare.gov or by phone with 1-800-MEDICARE. If you are enrolled in one of the three Kaiser Permanente plans not returning for 2027, use the Annual Enrollment Period to pick a replacement so your coverage continues on January 1, 2027. If your plan is renewing, you can stay in it without taking any action.
