An Act relative to copay assistance

This bill prevents health insurance plans from dropping coverage for a branded drug solely because an FDA-approved generic equivalent is available. Insurers must wait at least three months after the generic becomes accessible in Massachusetts before discontinuing the branded drug. The Department of Public Health determines when the generic is "available" by checking pharmacy stock, supply levels, and patient access barriers. It directly affects patients prescribed branded drugs and insurers offering coverage within Massachusetts. The law ensures continuity of care during the transition period to generic alternatives.
