Pharmacy benefit manager act enhancements.

HB 191 regulates pharmacy benefit managers (PBMs) in Wyoming to protect pharmacies and patients. It requires PBMs to report quarterly on drug reimbursement appeals, including denial reasons and cost adjustments, and prohibits retroactive claim denials or fees for claim processing. The bill bans PBMs from basing pharmacy payments on patient outcomes without prior agreement, restricting point-of-sale fees, and preventing unfair contract changes without 45 days' notice. These provisions directly affect pharmacies and pharmacy designees that contract with PBMs, aiming to ensure fair reimbursement practices and transparency.
