Pharmacy benefit manager amendments.

HB 173 requires pharmacy benefit managers (PBMs) and insurers to include retail pharmacies in patients' network choices without using financial incentives like reduced copays to steer patients toward specific locations. It mandates the Wyoming Department of Insurance to create rules ensuring adequate in-network pharmacy access, including location requirements. The law, effective January 1, 2025, directly affects patients (who gain more pharmacy choice), retail pharmacies (protected from exclusion), and PBMs/insurers (prohibited from using cost-sharing tactics to limit options). It focuses on transparency and network adequacy without altering prescription drug pricing or coverage.
