UnitedHealthcare has circulated a preliminary list of Medicare Advantage markets it may abandon for the 2027 plan year, and the early tally reaches into 34 counties spread across a dozen states. If the insurer follows through, roughly 20,000 members would lose their current plans and have to line up replacement coverage during the fall enrollment season. Nothing on that list is locked in, but for the households in those counties the possibility alone is reason to start planning now rather than in December.
What UnitedHealthcare is actually weighing
The county list making the rounds is an early, internal-style draft shared in the first week of August, not the binding contract the company files with regulators. Insurers finalize their Medicare Advantage service areas over the summer and into early fall, and the numbers can shift before anything is official. UnitedHealthcare has described the markets as under review, which means some counties on the list could stay and others not yet named could be added.
Concrete answers arrive on a fixed date. Official 2027 plan details, including which plans exist in which counties and at what cost, become public on October 1, ahead of the Annual Enrollment Period that runs from October 15 through December 7. Reporting on the draft 34-county exit list stresses that it remains subject to change until those filings are locked.

Why insurers keep retreating from certain counties
The pullback is not new, and it is not limited to one company. UnitedHealthcare already shed Medicare Advantage plans serving more than 600,000 members going into 2026, and rivals including Humana and Aetna trimmed their footprints for the same year. The 34-county review for 2027 is the next chapter of that same retreat.
The driver is arithmetic. Medical costs among older enrollees have climbed faster than the payments insurers collect, federal risk-adjustment and payment rules have tightened, and thinly populated rural counties are often the least profitable to serve. When a market stops penciling out, carriers exit it rather than absorb the loss, and the members in that county become collateral. For a retiree on a fixed income, that can mean losing a $0-premium plan, a familiar provider network, or extra benefits such as dental and vision that the next available plan may not match.
What a non-renewal actually triggers
A dropped plan is not the same as being left without options. When a Medicare Advantage plan is discontinued or pulls out of a service area, the affected members qualify for a Special Enrollment Period that opens a window to choose a new Medicare Advantage plan or return to Original Medicare. Anyone returning to Original Medicare also gains a guaranteed-issue right to buy certain Medigap supplement policies without answering health questions, a protection that matters most for those who have developed conditions since first enrolling. The full menu of coverage moves after a plan ends is laid out on the government’s coverage-options page, and the guaranteed-issue rules sit on the Medigap buying page.
The cost of doing nothing is the real risk. A member who ignores a non-renewal notice can be shifted into a default option or left with a gap in coverage, and missing the guaranteed-issue window can mean facing medical underwriting later and higher premiums or outright denial.
How members in the 34 counties can protect themselves
The first warning does not wait until October. Every Medicare Advantage plan mails an Annual Notice of Change each September spelling out how the plan will change, or whether it will vanish, for the coming year. Reading that notice the day it arrives, rather than setting it aside, is the single most useful step. From October 1, the plan comparison tools at medicare.gov show the actual 2027 lineup for any ZIP code, and the Annual Enrollment Period that opens October 15 is the window to act.
Households that suspect their county is on the review list can call their current plan or a State Health Insurance Assistance Program counselor for free help sorting the options. The one date that settles the guessing is October 1, when UnitedHealthcare’s final 2027 service area, and every plan it is keeping or dropping, stops being a draft and becomes the record retirees can plan against.
