The bill amends Sections 27-18.2-3 and 27-18.2-3.1 of the General Laws to enhance consumer protections for Medicare Supplement Insurance Policies. Key insertions include the establishment of standards that prohibit benefits duplicating Medicare coverage and limit exclusions for preexisting conditions to six months prior to coverage. It also mandates the commissioner to adopt regulations ensuring fair practices in policy provisions, premium rates, and claims payments, while aligning with federal law. A significant addition is the introduction of a six-month open enrollment period for individuals under 65 who qualify for Medicare due to disability or end-stage renal disease, allowing them to apply for any available Medicare supplement policy upon turning 65.

The bill also includes important deletions, such as the removal of guaranteed issue rights for individuals enrolled in Medicare Parts A and B during an annual enrollment period, which previously required enrollment in a Medicare Advantage plan. Instead, it guarantees issue rights for individuals with continuous coverage and no gaps exceeding 90 days from their Medicare supplement open enrollment period, ensuring no medical underwriting is performed for these applicants. Furthermore, the bill prohibits the use of gender, attained-age, or issue-age in rating structures for policies issued on or after January 1, 2026, enforcing community rating as the sole methodology. Individuals with existing policies that utilize the now-prohibited rating structures can maintain their coverage or switch to new policies starting January 1, 2026. The act aims to make Medicare Supplement insurance more affordable and accessible, taking effect immediately upon passage.
