Short answer: Your window is 7 months around your 65th birthday — enroll in the first 3 months. And know Washington's advantage: once you have a Medigap plan, WA generally lets you switch plans year-round without health questions (to equal or lesser benefits) — so your Supplement rate is never a life sentence.
This one's personal — Washington is our home state. iCoach Solutions is headquartered in Tacoma, and most of our team lives and works right here in the South Sound. Here's the turning-65 playbook for Washingtonians.
Your 7-month Initial Enrollment Period
The window: 3 months before your birthday month, the month itself, and 3 months after. Enroll early for coverage that starts the first of your birthday month. Miss it without creditable coverage and the Part B penalty (10% per year, for life) and Part D penalty apply.
WA's advantage: the Medigap switch rule
In most states, once your Medigap enrollment window passes, switching Supplement plans means health underwriting — and a possible decline if your health has changed. Washington law works differently: current Medigap policyholders can generally move to another Medigap plan any time of year, without medical underwriting (when switching to equal or lesser benefits). Practically, that means when your carrier raises rates, you can shop — a lever most of the country doesn't have.
Advantage vs. Original + Supplement in Washington
From Seattle and Tacoma to Spokane, Washington's Advantage plans are competitive — but network fit matters across our hospital systems (MultiCare, Virginia Mason Franciscan, UW Medicine, Providence). Original Medicare + a Supplement opens nearly every door, and thanks to the switch rule, your Supplement choice stays flexible.
