Relating to applicability of certain prescription drug insurance laws to health benefit plans and pharmacy benefit managers.

HB 5102 requires pharmacy benefit managers (PBMs) to follow existing prescription drug insurance laws for all health benefit plans they administer, regardless of whether specific plan details are listed in the law. It directly affects PBMs and health plans serving Texas residents, applying to all such plans even if contracts are handled outside Texas. The key provision mandates universal compliance with these laws for covered plans, removing exceptions for plans not explicitly named. This applies only to health benefit plans delivered, issued, or renewed on or after January 1, 2026, with the law taking effect September 1, 2025.
