A major hospital system on Florida’s Gulf Coast is walking away from every contract it has with UnitedHealthcare, a split that will leave its hospitals and physicians out-of-network for tens of thousands of insured patients, including a large share of Medicare Advantage members, starting in the new year.
Lee Health’s Break With UnitedHealthcare Becomes Official
Lee Health, the dominant hospital system serving Fort Myers and the surrounding Southwest Florida region, has confirmed on its own website that it is ending its Hospital Participation Agreement and Medical Group Participation Agreement with UnitedHealthcare, effective Dec. 31, 2026. Starting Jan. 1, 2027, every Lee Health hospital and physician across all of its locations will no longer be considered in-network for UnitedHealthcare members enrolled in employer-based, individual or Medicare Advantage plans. UnitedHealthcare has said the termination notice arrived without warning, while Lee Health has pointed to a pattern of prior-authorization requirements, utilization reviews and claim denials that it says interfere with timely patient care, with roughly a third of the system’s medical-necessity denials tied to UnitedHealthcare’s Medicare Advantage plans.
The break is total rather than partial: it covers every Lee Health hospital, every affiliated physician group and every UnitedHealthcare plan type named in the notice. The one meaningful carve-out is UnitedHealthcare’s Exchange and Marketplace plans, which the insurer says already do not include Lee Health as an in-network provider today, so nothing changes there either way.

What Changes on January 1 for a Medicare Advantage Member
Nothing changes for the rest of 2026. Lee Health says its hospitals and physicians remain in-network with UnitedHealthcare commercial and Medicare Advantage plans through Dec. 31, and patients should keep any appointments, tests or procedures scheduled for this year. Traditional Medicare beneficiaries who carry a UnitedHealthcare or AARP Medigap or Medicare Supplement policy are unaffected entirely, because that coverage pays secondary to Medicare rather than running through a network at all.
The people who need to pay attention are UnitedHealthcare Medicare Advantage enrollees who rely on Lee Health hospitals or physicians for ongoing or scheduled care. Beginning Jan. 1, seeing a Lee Health provider without an exception could mean materially higher out-of-pocket costs, since out-of-network Medicare Advantage claims typically carry a much smaller share of coverage than in-network care, if they are covered at all outside of an emergency. Lee Health has flagged pregnancy, complex treatment plans and chronic-illness care for special attention, urging patients in those situations to contact UnitedHealthcare directly about Continuity of Care protections that can preserve in-network rates for a limited time even after a contract ends.
Continuity of Care and the Path Back to In-Network Status
UnitedHealthcare’s Continuity of Care process, along with protections required elsewhere under federal or state law, is the main mechanism available to patients who are mid-treatment when a contract like this one lapses. Lee Health is directing members to call the number on the back of their UnitedHealthcare card as soon as possible to ask whether their specific treatment qualifies, rather than waiting until January to find out. For anyone with a 2027 appointment already on the books, Lee Health has said not to cancel without first understanding the alternatives, including whether an earlier 2026 appointment date might still be available.
Both sides have left the door open to a resolution before the Dec. 31 deadline, though Lee Health has said publicly that it does not currently see a path toward bridging the disagreement. Emergency care remains covered at the in-network rate at any hospital regardless of contract status, under the federal law that guarantees emergency treatment access — the one part of this dispute that does not change no matter how the contract negotiations end.
A Medicare Advantage member who wants to avoid the disruption entirely still has one more option available this fall: Medicare’s Annual Enrollment Period runs from Oct. 15 through Dec. 7, giving Lee Health patients enrolled in a UnitedHealthcare Medicare Advantage plan a window to switch to a different Medicare Advantage plan, or back to Original Medicare, before the Jan. 1 out-of-network date takes effect. Lee Health has also published a running list of which health plans it expects to remain in-network beyond that date, a resource the system says it will keep updating as negotiations with other insurers continue on separate tracks. For a retiree weighing whether to wait out the dispute or switch plans during open enrollment, that list — not a general assumption about which insurers usually contract with a given hospital — is the detail worth checking directly.
