CMS crosswalk: members move into one of 2 plans in 11 of its 35 counties; in the others the plan ends
Wellpoint Full Dual Advantage (H1894-002) is not offered under this ID in 2027. The CMS plan crosswalk of October 1, 2026 moves its members into 2 2027 plans, each sold in part of its area (listed below), in the 11 counties where they are sold (1,709 members in September 2026). In its other 24 counties (307 members) there is no plan to move into: coverage ends December 31, 2026, and members there need to choose a new plan (counties with fewer than 11 members are not counted). The crosswalk also lists part of the plan as terminated without saying which members; your Annual Notice of Change says whether you move to a new plan or your coverage ends.
What changes for its members, plan by plan?
In 2026 the plan cost $9.10 a month with a $9,250 in-network limit. Each row compares that with one of the 2027 plans its members move into.

What can members do, and by when?
If you live in Grays Harbor (WA), Jefferson (WA), King (WA), Kitsap (WA), Lewis (WA), Mason (WA), Pierce (WA), Skagit (WA), Snohomish (WA), Spokane (WA), Thurston (WA)
- If you do nothing
- You are moved into one of the 2027 plans above on January 1, 2027. Your Annual Notice of Change names it.
- October 15 to December 7, 2026
- Open enrollment: choose another Medicare Advantage plan, or Original Medicare with a drug plan, instead.
If you live in Adams (WA), Benton (WA), Chelan (WA), Clallam (WA), Clark (WA), Columbia (WA), Cowlitz (WA), Douglas (WA), Ferry (WA), Franklin (WA), Garfield (WA), Grant (WA), Kittitas (WA), Klickitat (WA), Lincoln (WA), Okanogan (WA), Pacific (WA), Pend Oreille (WA), San Juan (WA), Skamania (WA), Wahkiakum (WA), Walla Walla (WA), Whitman (WA), Yakima (WA)
- Your coverage
- Ends December 31, 2026: none of its 2027 plans is sold where you live.
- October 15 to December 7, 2026
- Open enrollment: join another Medicare Advantage plan, or Original Medicare with a drug plan. Coverage starts January 1, 2027.
- December 8, 2026 to the end of February 2027
- A special enrollment period because the plan is leaving: you can still join a plan, but coverage starts the first day of the month after you join, so choose by December 31 to have no gap.
- If you do nothing
- You are enrolled in Original Medicare when the plan ends, without a drug plan unless you join one (with Extra Help or full Medicaid, Medicare enrolls you in one).
- Without a drug plan
- Going 63 days or more in a row without drug coverage can mean a late enrollment penalty if you join a drug plan later; joining by the end of February keeps a January and February gap under 63 days, waiting longer does not.
- If you have Medicaid or Extra Help
- You can switch to a different drug plan, or leave a Medicare Advantage plan for Original Medicare with a drug plan, once a calendar month; the change starts the first day of the next month.
