Modifies provisions relating to advanced practice registered nurses

HB 763 expands prescribing authority for certified advanced practice registered nurses (APRNs) in Missouri. It allows APRNs with a board-certified controlled substance prescriptive authority to prescribe Schedule III-V controlled substances and limited Schedule II medications (like hydrocodone for hospice patients), with prescriptions capped at a 120-hour supply without refill. The bill requires written collaborative practice agreements with physicians, specifies locations where APRNs may prescribe, and mandates patient disclosure statements about their care team. This directly affects APRNs, their collaborating physicians, and patients receiving care in settings like hospice or rural clinics, while maintaining restrictions on self-prescribing and certain high-risk medications.
