Medicare Advantage, Part D and supplements; impose certain requirements on companies that offer them to MS residents.

HB 1580 requires insurance companies selling Medicare Advantage plans, Part D plans, and Medicare supplement policies to Mississippi residents to follow specific rules. It mandates that companies pay agents and brokers fair market value commissions based on federal standards for Medicare Advantage and Part D plans, and use a flat fee model for supplement policies. The bill also creates a five-year open enrollment window for seniors aged 65-80 to switch plans without medical questions, and requires network providers to submit "intent to exit" notices by August 1 annually. Additionally, it separates data on independent agent contractors from employee agents and gives Mississippi’s Insurance Commissioner authority to enforce these rules. The bill, which died in committee in February 2026, would have directly affected insurers, agents, and healthcare providers operating in Mississippi’s Medicare market.
