Modifies provisions relating to collaborative practice arrangements between physicians and physician assistants

HB 2749 modifies Missouri's rules for physician assistants (PAs) working under physician supervision. It replaces outdated language with new definitions and clarifies that PAs must operate under a written "collaborative practice arrangement" with a licensed physician for all services. The bill explicitly lists permitted PA tasks (like taking patient histories, performing exams, and assisting in surgery) while banning PAs from performing abortions, prescribing vision correction devices, or administering certain anesthetics. This directly affects PAs and physicians in Missouri by defining their scope of practice and requiring formal written agreements for collaborative care.
