Pharmacy Benefits Managers - Definition of Purchaser and Alteration of Application of Law

SB 303 amends Maryland's insurance law to clarify that certain nonprofit health maintenance organizations (HMOs) are excluded from the definition of "purchaser" under pharmacy benefits manager (PBM) regulations. This specifically applies to nonprofit HMOs that operate internal pharmacy services exclusively for their own members, rather than through external PBM contracts. The bill removes regulatory requirements - such as formulary and rebate rules - from applying to these nonprofit HMOs when they manage pharmacy benefits internally. The change affects how existing PBM laws apply to these specific nonprofit health plans, reducing regulatory burden for their internal pharmacy operations.
