Florida has one of the largest Medicare Advantage enrollment populations in the country. Humana has been a major carrier in many Florida counties. Members in affected Florida markets who receive a plan termination notice have federal guaranteed-issue rights to enroll in certain Medicare Supplement plans — without medical underwriting.
Florida does not have state-level continuous open enrollment for Medicare Supplement plans (unlike a small number of other states). This makes the federal guaranteed-issue window especially important for Florida residents. Once the 63-day window closes, insurers can apply medical underwriting in Florida.
Plan G is the most commonly selected Medicare Supplement plan for new enrollees in Florida in 2026. Eligible beneficiaries whose Medicare Advantage plan is terminating may have a federal guaranteed-issue right to Plan G. Under the MACRA framework, Plan G is the applicable alternative to Plan F for people newly eligible for Medicare on or after January 1, 2020, where Plan G is offered. An independent broker can confirm which plans you qualify for based on your specific termination notice.
