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

OLYMPIA, Wash. — For the 2027 plan year, Anthem (which the Centers for Medicare & Medicaid Services groups under Elevance Health) is listed in the CMS Medicare Advantage Landscape with three Medicare Advantage plans available somewhere in Washington state. All three are HMO plans, all three are Dual Eligible Special Needs Plans (D-SNPs), all three include drug coverage, and all three are new for 2027. Two Anthem plans from 2026 are not returning. This article walks through what the federal file says and how a Washington reader can check whether any of those plans is actually offered in their own county.

What is Anthem offering across Washington for 2027?

Across Washington in 2027, Anthem has 3 Medicare Advantage plans in the CMS Landscape file. All 3 are HMO plans, all 3 are D-SNPs (designed for people who have both Medicare and Medicaid), and all 3 include Part D prescription drug coverage. Anthem has no Chronic Condition SNPs (C-SNPs) and no Institutional SNPs (I-SNPs) in Washington for 2027.

For context, the CMS file lists 15 carriers offering Medicare Advantage in Washington for 2027, with 115 plans statewide across all carriers. The table on this page shows the full carrier breakdown; Anthem accounts for 3 of those 115 plans.

Because D-SNPs are built for people with both Medicare and Medicaid, eligibility is narrower than a general Medicare Advantage plan. A reader who does not have Medicaid would typically not qualify for a D-SNP, regardless of county.

Which Anthem plans reach the most Washington counties in 2027?

The three Anthem Medicare Advantage plans in Washington for 2027 — Wellpoint Dual Advantage (HMO D-SNP), Wellpoint Dual Advantage Plus (HMO D-SNP), and Wellpoint Full Dual Advantage (HMO D-SNP) — are each offered in 11 Washington counties, according to the CMS Landscape file.

All three are HMO D-SNPs with drug coverage. Washington has 39 counties, so even the plans with the widest reach are not statewide. The full county list for each plan is shown in the table on this page; the point to carry forward is that "available in Washington" is not the same as "available where you live."

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

For 2027, all 3 of Anthem's Washington Medicare Advantage plans are new, and 2 plans Anthem offered in 2026 are not returning. That means every Anthem option a Washington reader sees for 2027 is a first-year plan under its current contract and plan identifier in the CMS file.

If you were enrolled in an Anthem plan in 2026 that is not continuing, your plan sponsor is required to send a written non-renewal notice before the Annual Enrollment Period. That notice explains your options, including guaranteed rights to return to Original Medicare and, in some cases, to buy a Medigap policy. The notice itself — not this article — is the authoritative document for your individual situation.

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

The most reliable way to check whether a specific Anthem plan is offered in your Washington county, and whether it covers your doctors and prescriptions, is to 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 to see the plans available in your county for 2027. From there you can:

• Look up each prescription by name and dosage to see how a plan handles it.
• Search the plan's provider directory for your primary care doctor, specialists and preferred hospitals.
• Read the plan's Summary of Benefits and Evidence of Coverage for the exact rules on cost sharing, referrals and prior authorization.

Because the three Anthem plans listed in Washington for 2027 are D-SNPs, confirming your Medicaid status with the Washington State Health Care Authority is also part of the eligibility picture.

What should Washington readers do before December 7, 2026?

Before December 7, 2026, Washington readers who want their 2027 Medicare coverage to start on January 1, 2027 should review their current plan's Annual Notice of Change, compare it against other options on Medicare.gov, and make any enrollment choice during the Annual Enrollment Period of October 15 – December 7, 2026.

A short checklist:

1. Read the Annual Notice of Change from your current plan (mailed in September 2026). 2. List your doctors, hospitals and prescriptions. 3. Compare plans by ZIP code on Medicare.gov, or call 1-800-MEDICARE. 4. If an Anthem D-SNP is on your list, confirm your Medicaid eligibility. 5. Enroll by December 7, 2026 for a January 1, 2027 effective date.

There is no need to rush. The dates are fixed, and the Medicare Plan Finder is available throughout the window.

Where can Washington residents get free help with Medicare for 2027?
