SB 1609 seeks to enact the Physician Assistant Licensure Compact, which aims to enhance access to medical services and improve the mobility of physician assistants (PAs) across states. This bill establishes a system for mutual recognition of PA licenses among participating states, allowing PAs to practice in multiple jurisdictions while ensuring adherence to local laws and safety standards. It outlines requirements for state participation, such as conducting criminal background checks and reporting adverse actions. The bill also sets up a national administrative body, the PA Licensure Compact Commission, responsible for managing the compact, implementing rules, maintaining a data system, and addressing disputes among states. Additionally, the bill authorizes states to charge fees for granting compact privileges and designates the physician assistant board as the administrator of the compact within Texas.
