A Washington city in a Portland medical market: PeaceHealth Southwest and Legacy Salmon Creek on this side of the river, OHSU and Kaiser Permanente Northwest across it, and Advantage networks that were built for two states.
What to know before you compare plans in Clark County
Clark County has a broad Advantage menu shaped by its place in the Portland metro. PeaceHealth Southwest Medical Center, Legacy Salmon Creek and the Vancouver Clinic anchor care on the Washington side; Kaiser Permanente Northwest — the Oregon-based Kaiser region — serves Clark and Cowlitz counties with its own plans and clinics; and many residents see specialists at OHSU or Legacy in Portland. Whether a given plan’s network crosses the river is the first thing we check.
Washington has no income tax and Oregon has no sales tax, which is why so many people retire to Vancouver and shop across the bridge; the Medicare version of that arbitrage is a Medigap policy, which works identically in both states without a network. Clark County veterans use the Vancouver campus of the VA Portland Health Care System.

Your options
Which kind of plan fits you in Vancouver?
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.
Clark County typically offers a broad Medicare Advantage menu, including plans with networks that reach into Portland, plus every Medigap carrier in Washington and the full Part D lineup. Availability is set by county and changes each plan year.
My specialist is at OHSU in Portland. Will a Vancouver plan cover that?
Some Clark County Advantage plans include Portland providers and some do not, and the contracts change each fall. A Medigap policy with Original Medicare covers OHSU, Legacy or PeaceHealth the same way on either side of the river. We confirm before you enroll.
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.
