Modifies provisions relating to prescriptive authority for advanced practice registered nurses and physician assistants

HB 1492 expands prescribing authority for certain advanced practice registered nurses (APRNs) and physician assistants in Missouri. It allows APRNs with specific certifications to prescribe Schedule III-V controlled substances and limited Schedule II medications (like hydrocodone), but only for hospice patients or those under designated mental health providers. Prescriptions for Schedule II/hydrocodone are restricted to 120-hour supplies without refills, and APRNs cannot prescribe for themselves or family members. The bill requires written collaborative agreements between APRNs and physicians outlining practice locations, patient disclosures, and protocols for prescribing controlled substances.
