Pharmacy benefit managers-prescription cost notification.

HB 63 requires pharmacy benefit managers (PBMs) in Wyoming to stop blocking pharmacies from sharing prescription cost details with patients or offering cheaper drug alternatives. The law directly affects pharmacies and pharmacists, who can now freely disclose cost differences between a patient's insurance coverage and out-of-pocket prices, and suggest more affordable options when available. PBMs cannot penalize or restrict these disclosures through contracts. The bill took effect on July 1, 2019, aiming to increase transparency in prescription drug costs without changing drug pricing itself.
