SB 535 Montana Senate · 2025 Regular Session

Revise laws related to experimental treatments

SB 535 revises laws related to experimental treatments, primarily by requiring experimental treatment centers to obtain a license from the state department. These centers must adhere to operational standards and pay licensing fees. The bill also mandates that licensed centers allocate 2% of their net annual profits to support access to experimental treatments for qualifying Montana residents. This allocation can be fulfilled by providing free treatment or contributing to a new Insurance Premium Support Account. This account is established to help fund health insurance premiums for eligible Montana residents who purchase insurance on the federal marketplace and meet specific income criteria.

MINOR
The bill was amended to remove references to several specific sections of the state code (37-3-103 and 50-12-110) from the list of sections being modified, likely to correct a clerical error or narrow the scope of amendments. Additionally, the bill added new requirements for the department to establish written policies and procedures alongside operational standards, and introduced a new section regarding an insurance premium support account, which establishes a funding mechanism for experimental treatments without reducing existing state funds.
