HB 1198 requires Tennessee health insurers and TennCare to allow patients to try biosimilar drugs (cost-effective copies of brand-name medications) before covering the original branded drug. It amends state law to permit health carriers to mandate a biosimilar trial for equivalent branded prescriptions, removing prior requirements for generic drug trials. The bill also directs TennCare’s pharmacy committee to consider biosimilar drugs when recommending medications for the state’s preferred drug list. These changes aim to reduce prescription drug costs by increasing biosimilar adoption, as stated in the bill’s legislative findings.
