Centene’s Wellcare brand is eliminating 133 Medicare Advantage plans across Oklahoma, Tennessee and Hawaii for the 2027 plan year, a retreat the company disclosed alongside its second-quarter results that will force roughly 340,000 members to find new coverage. The plans span 158 counties, several of them rural markets where Wellcare had been one of only a handful of insurers still competing for Medicare Advantage business. For members, the practical consequence is a hard deadline: pick a new plan during this fall’s open enrollment window, or default into coverage nobody actually chose for them.
A Named Carrier’s Retreat, County by County
Becker’s Payer counts Wellcare among at least five insurers stepping back from Medicare Advantage for 2027, and its cut is one of the larger moves in that group by plan count — 133 separate Medicare Advantage products discontinued at once, rather than a single plan pulled from a handful of counties. The exits concentrate in Oklahoma, Tennessee and Hawaii, three states where Wellcare had built out meaningful Medicare Advantage market share over the past several years.
Centene disclosed the pullback to investors alongside second-quarter results, framing it as part of a broader effort to shed Medicare Advantage business that was not generating adequate margin. The company is not alone in that calculation: insurers across the industry have spent 2026 trimming plans in counties where medical costs ran ahead of what CMS star-rating bonuses and premium revenue could cover, and Wellcare’s 340,000-member exit is one of the largest single moves in that wave so far.
The county-level concentration raises the stakes for members in smaller markets. A member in a metro area losing one Wellcare plan often has several competing Medicare Advantage options left to choose from; a member in a rural Oklahoma or Tennessee county where Wellcare was one of two or three insurers selling Medicare Advantage plans has a much thinner backup list, and in some counties, none at all.
The retreat is not limited to Wellcare’s own brand. Medicare Advantage insurers nationally have been paring back plans that carry a low CMS star rating, since those ratings determine bonus payments the insurer uses to fund extra benefits like dental or over-the-counter allowances. A plan that loses its bonus eligibility often becomes unprofitable well before the insurer’s broader Hawaii, Oklahoma or Tennessee market does, which is one reason a single company’s exit rarely stays confined to a single state.

The Switch Clock Runs October 15 to December 7
Medicare’s annual open enrollment period runs October 15 through December 7, and any plan change made inside that window takes effect January 1 — meaning a Wellcare member has a fixed six-and-a-half-week stretch to research and select a replacement before the old plan lapses. There is no extension built into the calendar for members whose plan happens to be one of the 133 being eliminated; they work against the same deadline as everyone else voluntarily switching plans.
Members who let the deadline pass are not left without coverage, but they lose the ability to choose it. Under federal rules, a member who does not select a new Medicare Advantage plan before their old plan ends is enrolled in Original Medicare rather than left uninsured — but Original Medicare alone leaves the 20% coinsurance on Part B services uncapped unless the member separately adds a Medigap policy or Part D drug plan, coverage a passive default will not supply.
Because Wellcare’s cut affects an entire slate of plans in each named county rather than one product being nudged out by a competitor, members cannot simply switch to another Wellcare offering in the same market the way they might if only a single plan were discontinued; the replacement has to come from a different insurer altogether, or from Original Medicare.
The Options Left When a Local Wellcare Plan Disappears
Members in counties that still have other Medicare Advantage carriers selling plans can shop among those alternatives through the Medicare Plan Finder, comparing which local doctors, hospitals and pharmacies stayed in-network under a different insurer’s contract — a check that matters most for members mid-treatment for a chronic condition, since a new insurer’s provider network rarely mirrors Wellcare’s exactly. Members in counties where Wellcare was effectively the only competitive option have a narrower path: Original Medicare paired with a standalone Part D plan and, if they act inside the guaranteed-issue window a full plan termination opens, a Medigap policy without medical underwriting.
Members can begin comparing 2027 plan details through Medicare’s official Plan Finder once new plan data goes live ahead of October 15, leaving roughly six weeks to compare premiums, drug formularies and provider networks before the December 7 cutoff arrives.
A member whose entire county loses Wellcare coverage also keeps the same guaranteed-issue option available to anyone dropped by a non-renewing plan: Original Medicare paired with a Medigap policy purchased without medical underwriting, so long as the application happens inside the window tied to the plan’s termination date. That path costs more out of pocket in monthly premiums than most Medicare Advantage plans, but it removes the network question entirely, since Original Medicare is accepted by any provider that takes Medicare at all.
What ties Wellcare’s 340,000-member exit to the rest of 2026’s Medicare Advantage retreat is the county-level math behind it: insurers are not leaving markets evenly, they are leaving the specific rural counties where medical costs ran highest relative to what CMS paid, which means the members facing the thinnest replacement options are disproportionately the ones in communities that already had the fewest choices to begin with.
