UnitedHealthcare Medicare Advantage in Washington for 2027: 25 Plans, County by County

OLYMPIA, Wash. — For the 2027 plan year, UnitedHealthcare is bringing 25 Medicare Advantage plans to Washington, according to the Centers for Medicare & Medicaid Services (CMS) Landscape Source Files. That statewide count includes a mix of HMO-POS and PPO designs, several Special Needs Plans built for specific situations, and most plans bundled with Part D drug coverage. Because Medicare Advantage is sold county by county, a plan listed statewide may or may not be available at your address.

This article, from an independent Medicare education site that is not affiliated with the government or with any insurance carrier, walks through what UnitedHealthcare is filing in Washington for 2027, what is new, what is leaving, and how to verify a plan in your own county before the Annual Enrollment Period closes on December 7, 2026.

What is UnitedHealthcare offering across Washington for 2027?

UnitedHealthcare has 25 Medicare Advantage plans on file in Washington for 2027, per the CMS Landscape Source File. The lineup breaks down as 15 HMO-POS plans and 10 PPO plans, with 23 of the 25 including Part D prescription drug coverage.

Fifteen of the 25 are Special Needs Plans: 10 Dual Eligible Special Needs Plans (D-SNP) for people with both Medicare and Medicaid, 3 Chronic Condition Special Needs Plans (C-SNP), and 2 Institutional Special Needs Plans (I-SNP) designed around long-term care settings. UnitedHealthcare is one of 15 carriers offering Medicare Advantage in Washington for 2027; across all carriers, Washington has 115 Medicare Advantage plans available somewhere in the state.

Which UnitedHealthcare Medicare Advantage plans reach the most Washington counties in 2027?

The widest statewide footprints among UnitedHealthcare's 2027 plans are its Dual Eligible Special Needs Plans. UHC Dual Advantage WA-V2 (PPO D-SNP) and UHC Dual Complete WA-Q1 (PPO D-SNP) are each filed in 31 Washington counties, and UHC Dual Advantage WA-V1 (HMO-POS D-SNP) and UHC Dual Complete WA-Q2 (HMO-POS D-SNP) are each filed in 30 counties.

Among plans open to the general Medicare population, the new AARP Medicare Advantage from UHC WA-18 (PPO) is listed in 21 counties, and AARP Medicare Advantage Patriot No Rx WA-MA02 (HMO-POS) is listed in 14. The two I-SNPs — UHC Care Advantage WA-E001 (PPO I-SNP) and UHC Nursing Home Plan WA-F001 (PPO I-SNP) — are filed in 14 and 15 counties respectively, but they are limited to people who meet the institutional-level-of-care criteria. The full county-by-county counts for every plan appear in the table on this page.

What is new or not returning from UnitedHealthcare in Washington for 2027?

UnitedHealthcare has 6 plans new for 2027 in Washington and 12 plans that are not returning for 2027, according to the CMS year-over-year comparison. The new entries include two PPO plans under the AARP brand — AARP Medicare Advantage from UHC WA-18 (PPO) and AARP Medicare Advantage from UHC WA-19 (PPO) — a new PPO without drug coverage called AARP Medicare Advantage Patriot No RX WA-MA3 (PPO), and three new C-SNPs: UHC Complete Care Support WA-1A, WA-2A, and WA-3A.

Several continuing plans were renamed. For example, plans previously branded "AARP Medicare Advantage Extras" or "AARP Medicare Advantage Essentials" are now listed as "AARP Medicare Advantage from UHC" with the same WA plan numbers, and the UHC Dual Complete WA-V001 and WA-V2 D-SNPs are now UHC Dual Advantage WA-V1 and WA-V2. A rename can look like a termination in a mailing, so it is worth comparing the plan ID letter you have today to the 2027 list.

If you are enrolled in one of the 12 plans not returning, CMS will send a non-renewal notice and you have a Special Enrollment Period to choose another plan; otherwise your coverage decision runs through the Annual Enrollment Period.

How do I check whether a UnitedHealthcare plan is offered in my Washington county and covers my doctors and drugs?

The authoritative place to check a 2027 plan in your Washington county is the Medicare Plan Finder at medicare.gov, which uses the CMS Landscape data at the county level. Enter your ZIP code and county, then filter by UnitedHealthcare to see only the plans actually available at your address.

Because Medicare Advantage is sold county by county, a plan listed in this statewide article — including the widest-reach plans named above — may not appear in your county, and plan details differ by plan. For doctors and hospitals, use the plan's provider directory; for prescriptions, use its formulary (drug list); for cost-share and extra benefits, use the plan's Evidence of Coverage. You can also call 1-800-MEDICARE, which operates 24 hours a day, 7 days a week.

What should Washington residents do before December 7, 2026?

Before December 7, 2026, review the Annual Notice of Change (ANOC) your current plan sent in September 2026 and compare it to the 2027 options in your county on medicare.gov. The Annual Enrollment Period runs October 15 – December 7, 2026, and the plan you pick in that window starts January 1, 2027.

A short checklist: confirm your plan is returning (remember UnitedHealthcare has 12 non-returning plans and 6 new plans for 2027); confirm your doctors are still in-network for 2027; confirm each of your prescriptions is still on the 2027 formulary; and confirm the plan is offered in your specific county, not just somewhere in Washington.

Where can Washington residents get free help with Medicare questions?

Two free, official resources are available to every Washington resident. Medicare.gov hosts the Plan Finder and plan documents, and 1-800-MEDICARE (1-800-633-4227; TTY 1-877-486-2048) answers questions 24 hours a day, 7 days a week, including help comparing plans in your county.
