An Act relative to non-medical switching

This bill prohibits health insurance carriers in Massachusetts from forcing patients to switch to cheaper alternative drugs if their current prescription is medically stable and was prescribed within the last six months. It specifically bans insurers from increasing costs, reducing coverage limits, or moving covered medications to more restrictive tiers during open enrollment or after a plan year begins. The law requires that coverage for these approved medications continue through the end of the patient's eligibility period unless the drug's safety is questioned by the FDA or its manufacturer.
