The bill amends the General Laws concerning Medicare Supplement Insurance Policies to enhance consumer protections through several key insertions and deletions. Notably, it establishes specific standards for policy provisions, including terms of renewability and eligibility conditions, while mandating a six-month open enrollment period for individuals under sixty-five who qualify for Medicare due to disability or end-stage renal disease upon reaching sixty-five. The bill also removes previous provisions that guaranteed issue rights during an annual enrollment period, replacing them with a broader guarantee for individuals with continuous coverage, ensuring that those with no gaps in coverage greater than ninety days have guaranteed issue rights for at least thirty days starting on their birthday.

Additionally, the legislation introduces new requirements for health insurance issuers, including the necessity to file and obtain approval for policy forms from the commissioner and to cover reasonable expenses incurred during the rate filing process. It prohibits the use of gender, attained-age, or issue-age in rating structures for Medicare supplement policies issued after January 1, 2026, enforcing community rating as the sole methodology. Individuals with existing policies that utilize the now-prohibited rating structures will be allowed to maintain their current coverage or switch to new policies starting January 1, 2026. The overall goal of the bill is to ensure that Medicare Supplement insurance remains affordable and accessible, thereby reducing disparities in coverage access for the public, with the act taking effect immediately upon passage.
