What Medicare Advantage plans does Wellcare offer in Seattle for 2027?

In King County, Wellcare offers 2 Medicare Advantage plans for 2027. Both are HMO-POS plans, both include drug coverage, and both are Dual Eligible Special Needs Plans (D-SNPs). The table below lists every plan by name.

In alphabetical order, the two 2027 plans are:

A D-SNP is a Medicare Advantage plan built for people who qualify for both Medicare and Medicaid. If you are not dual-eligible, you generally would not enroll in these plans. Plan details — premium, cost-sharing, network, drug list, extra benefits and star rating — come from the Medicare Plan Finder at medicare.gov, from 1-800-MEDICARE, or from each plan's Evidence of Coverage and provider and pharmacy directories.

What is new or not returning from Wellcare in King County for 2027?

Six of Wellcare's 2026 plans in King County are not being offered for 2027, and no new plans are being added. The two plans that are continuing are both renamed versions of 2026 plans.

If you are enrolled in a Wellcare plan that is not returning, Wellcare is required to send you a notice. You will also receive an Annual Notice of Change (ANOC) if your plan is continuing under a new name — that document spells out what is changing for 2027, including any changes to the drug list, provider network and cost-sharing. Read it before you decide to stay or switch.

What happens if my Wellcare plan is not returning in 2027?

If your plan is leaving the county, you will not be left without a path. You can pick another Medicare Advantage plan during the Annual Enrollment Period, which runs October 15 through December 7, 2026, for coverage that starts January 1, 2027. You can also return to Original Medicare and, if you want drug coverage, add a stand-alone Part D plan. In many cases, losing a plan triggers a Special Enrollment Period as well; medicare.gov and 1-800-MEDICARE can confirm your specific options.

There are other carriers in the county. For 2027, 10 other companies offer Medicare Advantage in King County, with 59 plans in all. That is the pool you can shop from on the Plan Finder.

How do I check a plan against my doctors and prescriptions before December 7?

Go to medicare.gov and use the Plan Finder. The tool lets you enter your ZIP code, add your prescriptions with doses, and add your preferred pharmacies, then shows each plan's estimated yearly drug cost, formulary tier for each drug, and whether a pharmacy is in network. For doctors and hospitals, use the specific plan's online provider directory or call the plan — networks change each year, and a provider who was in network in 2026 may not be in 2027.

A short checklist that works for any plan:

What Medicare rules and dates should Seattle residents know for 2027?

The Annual Enrollment Period runs October 15 through December 7, 2026. A change you make in that window takes effect January 1, 2027. If you do nothing, your current plan renews for 2027 if it is being offered, with the changes listed in its ANOC. There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31, 2027, when people already in a Medicare Advantage plan can switch to another MA plan or go back to Original Medicare once.

A few program-level figures to keep in mind:

Frequently asked questions

Is Wellcare the same as Centene?
Yes. CMS lists this carrier as Centene (WellCare); Wellcare is the brand name used on the plan documents. If you see "Centene" in CMS data and "Wellcare" on your card, they refer to the same company.
I have a Wellcare plan that is being renamed — do I need to do anything?
Not necessarily. If your plan is continuing under a new name, your coverage will roll over on January 1, 2027. Read the Annual Notice of Change you receive from Wellcare, because the renamed plan can still have different cost-sharing, a different drug list or a different network than it did in 2026. If anything important to you has changed, you can switch plans by December 7, 2026.
What if I am not dual-eligible — can I enroll in Wellcare's 2027 plans in King County?
Both of Wellcare's 2027 Medicare Advantage plans in the county are D-SNPs, which are built for people with both Medicare and Medicaid. If you are not dual-eligible, those plans are generally not available to you. You can compare plans from the other 10 carriers in the county on the Medicare Plan Finder.
Where can I get help that is specific to my situation?
Go to medicare.gov to use the Plan Finder, or call 1-800-MEDICARE (TTY 1-877-486-2048), which is open 24 hours a day, seven days a week. For details about a specific plan, the plan's Evidence of Coverage and its provider and pharmacy directories are the official source. For personalized answers, use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE. The deadline to make a change for 2027 coverage is December 7, 2026.
