relative to regulation and transparency of pharmacy benefit manager practices.

SB 547 regulates pharmacy benefit managers (PBMs) in New Hampshire to increase transparency and fairness in drug pricing. The bill requires PBMs to act in the best interest of health insurance companies (their clients) and bans them from keeping profits from "spread pricing" - where PBMs charge health plans more than they pay pharmacies for drugs. It defines key terms like "affiliate" and "revenue," and mandates that PBMs pass all rebates from drug manufacturers to health plans rather than retaining them. This directly affects PBMs, health insurers, and pharmacies, aiming to address high drug costs (23% of healthcare spending) and patient cost concerns (25% skip doses due to expense).
