requiring notice to the insurance department of the discontinuance of certain types of insurance, including Medicare Advantage Plans.

SB 121 requires insurance companies licensed in New Hampshire to provide 90 days' written notice to the state insurance department before stopping an entire line of insurance business or making significant changes to Medicare Advantage Plans. Specifically, it mandates notice for insurers ending Medicare Advantage Plan offerings in a county, modifying their contracts with Medicare, or substantially changing plan features. The law applies directly to insurance companies selling these plans in New Hampshire, ensuring the department is notified well in advance of any major service disruptions. This creates a formal process for transparency and allows time for potential mitigation efforts. The bill became law on July 15, 2025, and takes effect September 13, 2025.
