Texas has one of the largest Medicare Advantage enrollment populations in the country, and Humana has been a major carrier in many Texas markets. Members in affected Texas areas who receive a plan termination or non-renewal notice have federal guaranteed-issue rights to enroll in certain Medicare Supplement plans — without medical underwriting.
Texas does not have a state-level Birthday Rule or continuous open enrollment for Medicare Supplement plans. This makes the federal guaranteed-issue window especially important for Texas residents. Once the 63-day window closes, insurers can apply medical underwriting in Texas, which may result in higher premiums or denial of coverage based on health history.
Plan G is the most commonly selected Medicare Supplement plan for new enrollees in Texas 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. An independent broker can confirm which plans you qualify for based on your specific termination notice.
