Relating to the relationship between pharmacists or pharmacies and health benefit plan issuers or pharmacy benefit managers.

HB 3317 requires health benefit plans and pharmacy benefit managers (PBMs) to include a unique identifier on enrollee ID cards, allowing pharmacists to verify if a plan is regulated by the Texas Department of Insurance. It prohibits denying or reducing claim payments after adjudication unless claims were submitted fraudulently, involved duplicate payments, or resulted from significant non-clerical errors by the pharmacy. The bill also restricts recouping payments to only the dispensing fee, not drug costs or other claim-related amounts. These provisions directly affect pharmacies, pharmacists, and health benefit plans/PBMs operating in Texas, excluding Medicaid, Medicare, and other specified programs.
