The state capitol, with Providence St. Peter and MultiCare Capital Medical Center in town, Kaiser’s Olympia medical center, and thousands of state retirees whose PEBB coverage has its own Medicare rules.
What to know before you compare plans in Thurston County
Olympia’s care is split between Providence St. Peter Hospital and MultiCare Capital Medical Center, with Kaiser Permanente Washington’s Olympia medical center as a third path and Tacoma or Seattle for tertiary care. Thurston County’s Advantage menu is moderate to broad, and the network question is which of the two hospitals, and which Tacoma specialists, a plan includes.
The bigger local wrinkle is employer coverage. Thurston County is full of retired state employees, and the PEBB retiree program has its own Medicare enrollment rules and its own plans; leaving it can be hard to undo. JBLM’s southern retiree communities in Lacey, Yelm and Tumwater add a TRICARE For Life layer. We sort out which layer you have before we compare anything.

Your options
Which kind of plan fits you in Olympia?
Medicare Advantage
All-in-one Part C plans, often $0 premium, that use a local network — so whether UW Medicine, Providence, MultiCare or Kaiser is in it matters as much as the price.
Medigap pairs with Original Medicare and lets you see any provider in the country that accepts Medicare — and in Washington you can change plans any time.
Thurston County typically offers a moderate-to-broad Medicare Advantage menu, every Medigap carrier in Washington, and the full Part D lineup. Lewis and Mason counties have fewer Advantage plans. We compare what is sold at your address.
I am a retired state employee on PEBB. What should I know?
PEBB retiree coverage has its own Medicare enrollment rules and its own Medicare plans, and leaving it can be hard to undo. Talk to us before you assume the ordinary employer rules apply; we walk through how PEBB fits with Medicare, Medigap and Part D.
How much does your help cost?
Nothing. Independent agents are paid by the carriers when you enroll, so comparing plans and reviewing your coverage each year is free to you.
