A bill for an act relating to Medicare supplement policies and an annual open enrollment period.

HF 308 establishes an annual 31-day open enrollment period for Medicare supplement insurance, beginning March 1 each year starting January 1, 2026. It directly affects individuals seeking Medicare supplement policies, including those under 65 who qualify for Medicare due to disability, end-stage renal disease, or environmental hazard exposure. During this period, insurers must offer at least one policy without denying coverage, charging higher premiums based on health status, or excluding preexisting conditions. Insurers are also required to provide applicants with notice of this enrollment period as directed by the Iowa Insurance Commissioner.
