One of Southwest Florida’s largest hospital systems has told the country’s biggest health insurer it is done doing business together, and the fallout lands squarely on Medicare Advantage enrollees around Fort Myers. Lee Health notified UnitedHealthcare on August 26 that it is ending its hospital and physician contracts, a move that will push every Lee Health facility out of network for a specific set of UnitedHealthcare plans starting in the new year. For patients who have built years of care around Lee Health’s doctors and hospitals, the clock on switching plans or switching providers is now running.
What Lee Health Actually Announced
A hospital system does not usually cut ties with a major insurer without expecting real disruption for the patients caught in between, and Lee Health’s announcement makes clear it is prepared for exactly that. The decision reaches every corner of the system, from routine primary care visits to major surgical admissions, and the specific plans losing access are spelled out in Lee Health’s own notice to patients.
According to Lee Health’s own patient notice, the system is ending its Hospital Participation Agreement and Medical Group Participation Agreement with UnitedHealthcare effective December 31, 2026. Starting January 1, 2027, Lee Health hospitals and physicians will no longer be in-network for UnitedHealthcare’s affected employer-based, individual, and Medicare Advantage plans. The change does not touch UnitedHealthcare or AARP Medigap supplement policies, which Lee Health says it will keep billing as secondary to traditional Medicare exactly as it does today, and emergency care remains covered everywhere under federal law regardless of network status.
Lee Health has not published how many patients the change affects, and none is claimed here. What is confirmed is the scope: every hospital and physician across the entire Lee Health system, in every location, loses in-network status for those UnitedHealthcare plan categories on the same date.
Why Lee Health Says It’s Walking Away
Lee Health’s public position, reported by Becker’s Payer Issues, centers on two complaints: that roughly one-third of the system’s medical necessity denials trace back to UnitedHealthcare Medicare Advantage plans, and that UnitedHealthcare owes Lee Health more than $100 million in disputed and underpaid claims. UnitedHealthcare has pushed back, telling Becker’s the issues were never raised with the insurer before the notice went out and that more than four months remained on the existing contract for the two sides to negotiate. Whatever the merits on either side, the practical effect for a Medicare Advantage enrollee is the same: coverage that works today is scheduled to stop working on a specific date, over a dispute the patient had no part in.
What Lee Health Itself Is Telling Patients
Lee Health, the system that dominates Lee County in hospitals and clinics, addressed the dispute directly in a statement provided to Florida public radio: “We understand this announcement may concern patients, families, and employers across Southwest Florida, and we did not make this decision lightly. Our commitment remains unchanged: putting patients first, minimizing disruption to care, and working closely with physicians, community partners, and health plan partners to help ensure patients have access to the care they need, when and where they need it.” The system pointed patients toward its website and a dedicated phone line, 239-320-1234, for questions about whether a specific UnitedHealthcare plan is affected by the change.
What Stays Covered and What Doesn’t
Through the end of 2026, nothing changes — Lee Health says patients should keep scheduled appointments, tests, and procedures as planned. After January 1, 2027, a UnitedHealthcare Medicare Advantage enrollee who continues seeing a Lee Health provider could be billed at out-of-network rates unless one of two exceptions applies: the visit is a true emergency, or the patient qualifies for UnitedHealthcare’s continuity-of-care process, which can preserve in-network pricing temporarily for people in the middle of an active course of treatment. Lee Health directs patients to call the member services number on their UnitedHealthcare card to apply for that continuity-of-care coverage well before the cutover date, since approval is not automatic.
The Timeline That Actually Matters
The dates line up in a way that gives affected enrollees a real window to act. Medicare’s fall Annual Enrollment Period, which runs October 15 through December 7, 2026, closes before the January 1 network change takes effect — meaning anyone who wants to switch out of an affected UnitedHealthcare Medicare Advantage plan and into a different insurer’s plan can do so with coverage starting exactly when the Lee Health network change begins. Enrollees who miss that window still get one more chance during the Medicare Advantage Open Enrollment Period, which runs January 1 through March 31, though by then they would already be experiencing the network gap for however long the switch takes to process.
What Affected Patients Should Do Now
Lee Health has built a running list, at leehealth.org/insurancecoverage, of which health plans it expects to remain in-network beyond January 1, 2027, and that list is the fastest way to check whether a specific plan is actually affected before assuming the worst. For anyone whose plan is on the departing list and who wants to keep their current Lee Health doctors, the fall enrollment period is the moment to compare Medicare Advantage plans that still include those providers, rather than waiting until the new year to discover the network has already changed. For anyone mid-treatment, the continuity-of-care application through UnitedHealthcare is worth starting now, since Lee Health’s notice makes clear that approval is not guaranteed and processing takes time the December 31 deadline does not leave much room for…
