HB 2190 creates Arizona's participation in a physician assistant (PA) licensure compact, allowing PAs licensed in Arizona to practice across state lines in other participating states without obtaining separate licenses. It directly affects PAs (especially military families who relocate) and patients seeking care from PAs in multiple states. The key mechanism is "compact privilege," which grants PAs the right to practice in a "remote state" (where the patient is located) under that state's laws, while requiring PAs to follow the rules of the patient's location. Arizona's licensing board retains authority to take disciplinary action against PAs practicing under the compact, and the bill mandates mutual recognition of licenses, criminal background checks, and reporting of adverse actions to a shared data system.
