When Your Medicare Plan Leaves Grays Harbor County

Three out of four people on Medicare in Grays Harbor County use Original Medicare. CMS counted 22,691 beneficiaries here in July 2026; 16,856 were on Original Medicare and 5,835 were in Medicare Advantage and other health plans. So if a Medicare Advantage plan has written to tell you it won't cover Grays Harbor after December 31, 2026, you have the same two options as anyone else: another Medicare Advantage plan or Original Medicare.

Two other numbers stand out more than the split, and they change what I'd tell a Grays Harbor reader to look at first.

Grays Harbor's Medicare profile

Source: CMS Medicare Monthly Enrollment, July 2026 (people, not plans). Shares computed. Population 65+: 21,012, or 27.0% of the county (WA OFM, April 2025).

Look at the drug lines too. Of the 17,094 Grays Harbor residents with a Medicare drug plan, about two-thirds (11,555) had a stand-alone Part D plan rather than drug coverage folded into a Medicare Advantage plan. Statewide it's closer to 40%. So a stand-alone drug plan is the ordinary setup in this county, not the exception. If you switch to Original Medicare, you will be picking that drug plan yourself. Enter your exact prescriptions and doses in Medicare Plan Finder and pick your usual pharmacy, because the same drug can cost very different amounts from one plan to the next.

One in eight is under 65, and that changes the Medigap answer

About 12% of Grays Harbor's Medicare population qualifies because of a disability, compared with 8% statewide. If that's you, read this part twice.

Washington's guaranteed issue law for a plan that ends, RCW 48.66.055, has no age limit written into that section. But insurers only have to offer the Medigap policies they sell to new customers, and federal law generally doesn't require Medigap sales to people under 65. Washington isn't on the CMS guide's list of states that require it. OIC's own page puts it plainly: if you're under 65 on Medicare due to disability, your options are more limited. So before you leave a Medicare Advantage plan expecting to pick up a Medigap policy, call SHIBA at 800-562-6900 and ask what's actually available to someone your age. When you turn 65 you get a fresh six-month Medigap open enrollment period.

If you're 65 or older, the Medigap right is straightforward. Move to Original Medicare and an insurer must sell you certain plans without health questions: Plans A through F (including high-deductible F), K or L if you were first eligible for Medicare before 2020; A, B, D, G (including high-deductible G), K or L if you were first eligible on or after January 1, 2020. OIC says to apply no earlier than November 1. The right ends March 4, 2027.

Nearly one in five has Apple Health too

The 4,231 dual-eligible residents (2,539 with full Apple Health, 1,692 partial) have a few extra protections when a plan leaves:

• If you get Extra Help, CMS reassigns you to a stand-alone Part D plan when your Medicare Advantage plan ends, unless you've already arranged 2027 drug coverage.
• With Medicaid or Extra Help, you can change stand-alone drug plans once each calendar month.
• With full Apple Health, you may join an integrated plan, which Washington calls Apple Health Medicare Connect, in any month where one is offered.

If money is tight and you have neither, ask about the Medicare Savings Programs. HCA says they have no asset test. Approval for one also qualifies you for Extra Help. Apply at washingtonconnection.org or through DSHS.

Deadlines, in plain order

1. Today until New Year's Eve: the old plan keeps paying claims.
2. December 7: regular Open Enrollment closes.
3. December 8 opens a special window for members of non-renewed plans; it stays open into late February.
4. December 31: the last day to choose for a January 1 start with no gap in coverage.
5. January 1, 2027: your new choice begins, or, if you made none, Original Medicare without any drug plan (Extra Help members get reassigned).
6. February 28, 2027: the last day of the plan-ending window. A February choice starts March 1.

Go 63 days or longer with no creditable drug coverage and Medicare may add a surcharge to your Part D premium for as long as you have Medicare drug coverage. The statewide discontinued-plan guide has the full rules.

Hospitals, distance, and getting to a new doctor

Grays Harbor covers about 1,902 square miles of land, from ocean beaches to the foothills at the base of the Olympic Peninsula. The state Department of Health lists two hospitals: Harbor Regional Health in Aberdeen (an acute care hospital) and Summit Pacific Medical Center in Elma (a critical access hospital). If you're comparing Medicare Advantage plans, check both, plus any Olympia or Centralia providers you see. Original Medicare has no network: any provider that accepts Medicare, here or in another state, is in.

Grays Harbor Transit's routes include 40 (East County / Olympia) and 45 (Oakville and Centralia). Its HarborFlex service combines certified paratransit with general-public dial-a-ride in Montesano, Elma, Westport and Ocean Shores; call 360-532-2770 to book.

Local help

Grays Harbor's SHIBA sponsor is Aging & Adult Services of Coastal Washington, the agency once named Olympic Area Agency on Aging, at 2700 Simpson Avenue in Aberdeen. On October 26, 2026, OIC's listing for it said "Currently not accepting appointments. For assistance, call Medicare at 1-800-633-4227." The statewide SHIBA line, 800-562-6900 (weekdays, 8:30 a.m. to 4:30 p.m.), was still listed, and its help is free. The agency's Community Living Connections line in Aberdeen is 360-532-0520 or 1-800-801-0060. 1-800-MEDICARE is open 24/7 except some federal holidays.

Aberdeen readers can go to the Aberdeen page for the city's own numbers.

Federal Medicare regulations and Washington statutes are the authority here, and the dates in your plan's letters are the ones that bind you; before you act, check with SHIBA, a licensed agent or Medicare's own line.
