Humana is not the only big insurer trimming Medicare Advantage plans for 2027. UnitedHealthcare, the largest player in the market, is preparing to pull out of dozens of counties, a move that would strip coverage from roughly 20,000 members. The company calls the list preliminary, but for anyone in an affected county the smart response is to treat a possible exit as real and get ready to shop.
The scope of the pullback
UnitedHealthcare’s preliminary plan for 2027 drops Medicare Advantage plans in 34 counties across 12 states, affecting about 20,000 of its members. The company has stressed to reporters that the county list is not final and could still change before plans are locked in. That caveat is genuine, but it cuts both ways: a member cannot count on being spared just because the list might shift.
This is a smaller cut than the company made for 2026, when it stopped offering plans in more than 100 counties affecting a far larger number of members. Taken together, the two years show a company deliberately shrinking its Medicare Advantage footprint rather than chasing enrollment at any cost.
For a member, the size of the national number matters less than a single question: is my county on the list? A 20,000-member cut is small next to UnitedHealthcare’s millions of enrollees, but it is total for the household whose plan is one of the ones ending. That is why a preliminary, company-wide figure is no comfort to an individual member and why checking your own county is the only number that counts.

Why members cannot confirm anything until October
A frustrating wrinkle is timing. Insurers are not permitted to confirm 2027 plan details to members until October 1, so a person worried about their plan cannot get a definitive answer during the summer. The preliminary list circulating now is an industry filing, not a member notice.
The formal word comes in the plan’s Annual Notice of Change, which must reach members by September 30, and in any separate non-renewal letter if a plan is being dropped. Until those arrive, the responsible move is to prepare for the possibility while waiting for the official confirmation.
What an exit costs a household
If a plan is dropped, the member does not keep it at a higher price; the plan ends. Without action, coverage reverts to Original Medicare with no drug plan and no cap on the 20% coinsurance Part B leaves in place. For a retiree managing chronic conditions, that exposure can be severe, which is why an exit is a budget event and not merely an inconvenience.
There is also the loss of bundled extras like dental, vision, and hearing coverage that Medicare Advantage plans often include and Original Medicare does not. Replacing those benefits, or doing without them, is part of the true cost of a plan disappearing.
The switching itself can carry hidden costs too. A new plan may use a different pharmacy network or place a member’s regular medication on a higher tier, and a member who moves to a new Medicare Advantage plan without checking its drug formulary can end up paying far more for the same prescriptions. Confirming that doctors and drugs carry over is not busywork; it is where the real dollars are won or lost when a plan disappears.
Using AEP to lock new coverage
The fix is the fall enrollment season. During the Annual Enrollment Period, which runs October 15 through December 7, an affected member can choose a new Medicare Advantage plan or move to Original Medicare with a stand-alone Part D drug plan for coverage starting January 1. A plan termination also opens a Special Enrollment Period that extends the deadline into early 2027.
A forced exit carries one valuable perk: a guaranteed-issue right to buy a Medigap policy without medical underwriting. That window is short, so anyone who wants Original Medicare plus a supplement should act early before insurers can screen for health conditions again.
Prepare now, decide in the fall
The sensible plan for a UnitedHealthcare member in one of the affected states is a two-step one: prepare now, decide in the fall. Note whether your county appears on the preliminary list, gather your list of doctors and prescriptions, and be ready to compare plans the moment the October confirmations land. If the plan survives, nothing is lost. If it does not, the member who prepared will choose new coverage calmly instead of scrambling after the deadline passes.
The wider pattern is worth understanding, because it is not going away. Insurers across the Medicare Advantage market are paring back plans as federal payment rates tighten and the companies prioritize profit margins over sheer enrollment. That means plan stability is no longer something a member can take for granted from one year to the next, regardless of which company they are with. Treating the fall review as an annual habit, rather than a task only when a letter arrives, is the surest protection against being caught out by the next round of exits.
