Relating to discriminatory practices by a health benefit plan issuer, pharmacy benefit manager, and third-party payor with respect to certain entities participating in a federal drug discount program.

HB 4422 prohibits health insurers, pharmacy benefit managers (PBMs), and third-party payors from discriminating against entities participating in the federal 340B drug discount program. The bill adds new requirements to Texas insurance law, mandating that these entities provide equal treatment to 340B-covered entities (such as hospitals and clinics that access discounted drugs through the federal program) when processing claims or payments. It directly affects health benefit plans, including insurance companies, HMOs, and specific state health plans listed in the bill. The key provision requires insurers and payors to avoid discriminatory practices like denying coverage or charging higher costs for drugs obtained through the 340B program. This policy change aims to ensure consistent access to discounted medications for qualifying healthcare providers.
