Grandview has a Community Living Connections office right in town, at 204 Port Point West. If your Medicare Advantage plan wrote to say it is done after December 31, 2026, that office and two phone numbers are where I'd start, before any comparison shopping.
Start here: three calls
- Community Living Connections, Grandview office: 509-402-0334. Run by Southeast Washington Aging and Long Term Care, the Area Agency on Aging for Yakima County. Community Living Connections lists it as serving older adults, persons with disabilities, and their families.
- SHIBA statewide line: 800-562-6900, Monday through Friday, 8:30 a.m. to 4:30 p.m. SHIBA is the state's free Medicare counseling program and doesn't sell anything. A caution: the local SHIBA sponsor for Yakima County is listed in Yakima, and on October 26, 2026 OIC's page showed it as "Currently not accepting appointments. For assistance, call Medicare at 1-800-633-4227." Use the statewide number.
- 1-800-MEDICARE (1-800-633-4227). Open 24 hours a day, 7 days a week, except some federal holidays. They can help you compare 2027 options.
Have your plan's letter, your Medicare card and a list of medicines in front of you when you call. It makes every call shorter.

CMS doesn't break Medicare enrollment down by city, so the county lines are the closest guide. Close to half of the county's Medicare population (46.5%) is in Medicare Advantage and other health plans, and almost one in four has Apple Health too. If that's you, mention it on every call; the rules for dual-eligible people are more flexible.
No hospital in town: what that means for networks
State hospital data lists no hospital inside Grandview. The closest one in the county data is Astria Sunnyside Hospital, a critical access hospital in Sunnyside; the two town centers are roughly 7 miles apart in a straight line. The county's acute care hospitals are in Toppenish and Yakima.
So for a Grandview resident, "is my hospital in the network?" isn't one question. If you're considering another Medicare Advantage plan, ask about each place you'd realistically end up: the Sunnyside hospital for urgent needs, Yakima for specialists or surgery, and wherever your primary care clinic sends people. Get the answer for 2027, not 2026.
Original Medicare works at any provider that accepts Medicare, with no network. The trade-off is cost-sharing with no yearly cap unless you add coverage.
The Medigap door, and when it closes
When a Medicare Advantage plan ends, Washington law (RCW 48.66.055) and federal law let you buy certain Medicare Supplement policies without answering health questions, as long as you go to Original Medicare. Here's how that window lines up:
| Date | What it means for Medigap |
|---|---|
| When the plan's notice reaches you | Your guaranteed issue right legally begins |
| November 1, 2026 | OIC's advice: send applications on or after this date |
| December 31, 2026 | Apply by now and a policy can start January 1 with no gap |
| March 4, 2027 | Right expires (63 days after the plan ends) |
Sources: RCW 48.66.055; WA OIC; Medicare's "Choosing a Medigap Policy" guide.
Which plan letters you can get depends on when you first became eligible for Medicare: before 2020, Plans A through F (high-deductible F too), K and L; on or after January 1, 2020, A, B, D, G (high-deductible G too), K and L. An insurer has to offer the ones it currently sells to new customers. If you're under 65 and on Medicare for a disability, choices are thinner in Washington; ask SHIBA before you plan around a Medigap policy.
A January mix-up to avoid
Two different windows run in early 2027, and people confuse them:
- The special enrollment period for your ending plan runs December 8, 2026 through February 28, 2027. Anyone whose plan left can use it to join a Medicare Advantage plan or a drug plan. December picks start January 1, January picks February 1, February picks March 1.
- The Medicare Advantage Open Enrollment Period, January 1 to March 31, is only for people who are already in a Medicare Advantage plan on January 1. If you did nothing and ended up in Original Medicare, it doesn't apply to you.
Translation: if you're drifting into January without a decision, your real deadline is February 28, not March 31. And remember that Original Medicare by itself has no drug coverage; unless you get Extra Help, in which case CMS assigns you a stand-alone drug plan, you'd have to join one yourself. The statewide guide explains the Part D penalty rules.
Buses out of Grandview
People For People's Community Connector routes charge no fare. Route 201 runs between Mabton, Grandview and Sunnyside. Route 200 continues from the Lower Valley up to Yakima and also reaches Prosser. Riders 60 and older and people with disabilities can book door-to-door trips two business days ahead at 509-457-1111. Apple Health members going to medical appointments can arrange rides through People For People at 1-800-233-1624.
Federal Medicare rules and Washington law are what govern here, and the dates in your own plan notice are the ones that count for you; check with 1-800-MEDICARE, SHIBA or a licensed agent if anything is unclear.
