Patients covered by Lee Health in southwest Florida got an insurance notice this month that reads differently depending on which UnitedHealthcare product sits in their wallet. Lee Health is ending its hospital and physician contracts with UnitedHealthcare, a split that will push several plan types out of network starting January 1, 2027. But Lee Health’s own notice draws a specific line: people with a UnitedHealthcare or AARP Medigap policy are not part of the change at all. That distinction is easy to miss in a notice built around a single insurer’s name, and it is the difference between a real disruption and no change at all for the same household.
What’s Actually Ending, And When
The dispute between the two organizations has been building for months, but the calendar now has a hard stop attached to it: a specific date when Lee Health’s contracts with UnitedHealthcare cease to exist, and another date when the network change actually takes hold.
Lee Health is terminating its Hospital Participation Agreement and Medical Group Participation Agreement with UnitedHealthcare, effective December 31, 2026, according to the health system’s own notice. Starting January 1, 2027, Lee Health’s hospitals and physicians will be out-of-network for UnitedHealthcare’s employer-based, individual, and Medicare Advantage plans. Appointments scheduled through the end of 2026 do not need to be rescheduled, and Lee Health says patients with 2027 appointments already on the books should not cancel them without first checking their options.

The Medigap Carve-Out, In Lee Health’s Own Words
Lee Health’s notice is explicit about who the split does not touch: “If you have traditional Medicare and a ‘Medigap’ or ‘Medicare Supplement’ through United or AARP, we will continue to bill your supplement secondary to your Medicare,” the health system states, adding that “this network change between Lee Health and UnitedHealthcare will not affect your Medicare Supplement coverage.” A second, separate carve-out applies to Florida Heart Associates, which Lee Health confirms is not part of the terminated contracts.
Why Traditional Medicare And Medigap Sit Outside The Fight
The distinction comes down to how each product works. A UnitedHealthcare or AARP Medigap policy supplements original Medicare, which pays hospitals and doctors directly under its own nationwide rules — there is no UnitedHealthcare network to be dropped from in the first place, so a contract dispute between Lee Health and UnitedHealthcare has nothing to bill against. A UnitedHealthcare Medicare Advantage plan works differently: it replaces original Medicare with a private plan built around a specific network, and that network is exactly what Lee Health is leaving. Someone holding both products in the same household, one spouse on Medigap and the other on Medicare Advantage, could see one bill completely unaffected and the other reshuffled entirely. That distinction is worth knowing before Medicare’s annual Open Enrollment period, which runs October 15 through December 7 this year, since it is the main window for switching out of a Medicare Advantage plan that is about to lose access to a preferred hospital system.
The two products are also mutually exclusive for any single Medicare beneficiary — a person cannot be enrolled in both a Medigap policy and a Medicare Advantage plan at the same time, so the question Lee Health’s notice is really asking each patient (“which UnitedHealthcare product do you actually have?”) has exactly one right answer per person, even inside a household where a married couple’s insurance cards can carry two different answers to that same question.
What Members On The Affected Plans Should Watch For
Patients with UnitedHealthcare’s employer-based, individual, or Medicare Advantage coverage may still qualify for continued in-network rates for a limited stretch through UnitedHealthcare’s Continuity of Care process, or as otherwise required by law, and Lee Health directs those patients to call the number on the back of their insurance card to ask about it. That process has a federal floor behind it, not just an insurer’s goodwill: under 42 U.S.C. § 300gg-113, a health plan must offer a transitional period of continued in-network treatment to a “continuing care patient” — defined as someone being treated for a serious and complex condition, receiving institutional or inpatient care, scheduled for nonelective surgery, pregnant and being treated for that pregnancy, or terminally ill and receiving treatment for the illness — and must keep paying the provider at the pre-termination rate during that window. That federal baseline is what gives Lee Health’s referral to the Continuity of Care process real weight for patients who fit one of those categories, rather than leaving it as a case-by-case courtesy. Anyone with a UnitedHealthcare Exchange or Marketplace plan is already out-of-network at Lee Health today; that particular carve-out predates this dispute and is not new. Lee Health’s FAQ is also careful to say it cannot help patients choose a replacement plan, pointing instead to Medicare’s own plan-comparison tool or the CMS helpline at 1-800-MEDICARE for anyone deciding whether to switch. Lee Health’s own explanation for why the talks broke down is blunt: “we do not see a path forward that would allow us to bridge our differences,” the health system says, leaving little room to expect a last-minute reversal before the new year. Coverage decisions made during Open Enrollment take effect January 1, the same date the Lee Health contract ends, so anyone weighing a plan switch because of this dispute is working against the same deadline.
