This explainer is published by an independent Medicare education site. It is privately owned, not part of the federal government, and not affiliated with Regence or any other insurance carrier.

A stable lineup on paper does not mean every detail inside a plan stays the same. Service areas, provider networks, formularies, and cost-sharing can shift from one plan year to the next even when the plan name and contract number are unchanged. The Annual Notice of Change that current members receive each fall is the document that spells those shifts out for the specific plan they are enrolled in.

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

Start at medicare.gov and enter the ZIP code and county. The Medicare Plan Finder will show which Medicare Advantage plans — from Regence BlueCross BlueShield of Oregon and the other 14 carriers in Washington — are actually available at that address for 2027.

From there, three checks matter most. First, confirm the plan name on this page appears in your county's results, since each of the four Regence plans is listed in only one Washington county. Second, type in each prescription so Plan Finder can show how the plan's formulary treats it. Third, look up each doctor, clinic, and hospital you want to keep in the plan's own provider directory, and if anything is unclear, call the plan to confirm the provider is in-network for 2027. Readers who prefer to work by phone can call 1-800-MEDICARE, which is open 24 hours a day, seven days a week.

What should Washington readers do before December 7, 2026?

The Annual Enrollment Period for 2027 Medicare Advantage coverage runs October 15 through December 7, 2026, and the choice made during that window takes effect January 1, 2027. Readers who are satisfied with their current coverage do not have to do anything to stay enrolled, as long as that plan is returning.

A useful order of operations is: read the Annual Notice of Change from any current plan, make a short list of must-keep doctors and prescriptions, run those details through Plan Finder at medicare.gov, and compare the results against any Regence plan listed in your county. People turning 65 or new to Medicare have their own Initial Enrollment Period tied to their birthday month, separate from the fall window.

Where can Washington readers get free help understanding 2027 Medicare Advantage choices?

Two free, official resources are available to every Washington reader. The Medicare Plan Finder at medicare.gov is the federal tool that shows the plans available at a specific ZIP code and county for 2027, with drug and provider look-ups built in. 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048, is staffed around the clock.

For plan-specific questions — what a benefit includes, whether a hospital is in-network, how a drug is tiered — the plan itself is the authoritative source through its member services line, its Evidence of Coverage, and its provider and pharmacy directories.
