Regence BlueShield Medicare Advantage in Washington for 2027: 2 Plans, County by County

OLYMPIA, Wash. — Regence BlueShield is bringing 2 Medicare Advantage plans to Washington for 2027, according to the Centers for Medicare & Medicaid Services (CMS) Landscape Source Files. Both plans include drug coverage, and each is offered only in certain counties — so whether a particular Regence plan is available where you live depends on your address.

This article is published by an independent Medicare education site. We are privately owned, not part of the government, and not affiliated with Regence BlueShield or any other insurance carrier. Our goal is to help Washington readers understand what the CMS files say for the coming year.

What is Regence BlueShield offering across Washington for 2027?

Regence BlueShield is offering 2 Medicare Advantage plans in Washington for 2027: 1 HMO and 1 PPO. Both of those plans include Part D prescription drug coverage, according to the CMS Landscape file for the 2027 plan year.

Regence is not listing any Special Needs Plans in Washington for 2027 — no Dual-Eligible SNPs (D-SNP), no Chronic Condition SNPs (C-SNP), and no Institutional SNPs (I-SNP). Readers who qualify for a Special Needs Plan based on Medicaid status, a chronic condition, or institutional care would need to look at other carriers on the Washington landscape.

For context, 14 other carriers are offering Medicare Advantage plans somewhere in Washington for 2027, and all carriers together account for 115 plans statewide. The full statewide list is shown in the carrier and plan tables on this page.

Which Regence BlueShield plans reach the most Washington counties in 2027?

Of the 2 Regence BlueShield Medicare Advantage plans listed for Washington in 2027, Regence MedAdvantage + Rx Enhanced (PPO) has the widest county reach at 5 counties, followed by Regence BlueAdvantage HMO (HMO) in 2 counties.

Both include drug coverage. Because Medicare Advantage plans are offered county by county, "statewide" here simply means the plan appears somewhere in Washington — not that it is sold in every county. Your ZIP code determines what you can actually enroll in. The plan-level table on this page shows each Regence plan and its reach; details such as premiums, copays, provider networks and drug formularies live on Medicare.gov and in each plan's Evidence of Coverage, not in this article.

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

For 2027, Regence BlueShield has 1 new Medicare Advantage plan in Washington and 3 plans from 2026 that are not returning, based on CMS Landscape files for both plan years. The new plan is Regence BlueAdvantage HMO (HMO).

If you are currently enrolled in a Regence plan that is not continuing into 2027, you should receive an Annual Notice of Change (ANOC) from the carrier describing what is happening to your coverage and your options. People in a discontinued plan generally have a Special Enrollment Period in addition to the regular Annual Enrollment window, but it is worth confirming your situation on Medicare.gov or by calling 1-800-MEDICARE.

Even if your plan is continuing, the ANOC is where year-to-year changes to costs, drug lists and provider networks are spelled out for 2027.

How do I check whether a Regence BlueShield plan is offered in my Washington county and covers my doctors and prescriptions?

To check whether a specific Regence BlueShield Medicare Advantage plan is offered in your Washington 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.

A few steps that tend to save time:

1. Enter your ZIP code on Medicare.gov. The Plan Finder will show only the plans actually sold in your county for 2027, including any Regence plans available at your address. 2. Add your prescription drugs exactly as prescribed — name, dose and quantity. The formulary is plan-specific and can change year to year. 3. Check provider networks directly with the plan or your doctor's office. Being "in network" for one Regence plan does not guarantee the same status in another. 4. Read the Evidence of Coverage (EOC) and Summary of Benefits for the plan you are considering before you enroll.

Because we are an independent education site, we do not quote plan premiums, copays, benefits, drug tiers or star ratings. Those details should always come from Medicare.gov or the plan documents themselves.

What should Washington readers do before December 7, 2026?

Before December 7, 2026, Washington readers should confirm their 2027 coverage during the Annual Enrollment Period, which runs October 15 through December 7, 2026. Any choice made in that window takes effect January 1, 2027.

A simple checklist:

• Read your current plan's Annual Notice of Change for 2027, if you have one.
• Make a list of your doctors, hospitals, pharmacies and prescriptions.
• On Medicare.gov, compare the plans available in your county — including the Regence BlueShield plans that serve your area, if any — alongside the 14 other carriers in Washington.
• Decide whether to keep your current coverage, switch Medicare Advantage plans, or move between Original Medicare and Medicare Advantage.

The deadline is a date on the calendar, not a reason to rush a decision you don't feel good about.

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