Modifies provisions relating to advanced practice registered nurses

HB 1635 expands prescribing authority for certified advanced practice registered nurses (APRNs) in Missouri. It allows APRNs with a special certificate to prescribe controlled substances in Schedules III, IV, and V, and certain Schedule II drugs (like hydrocodone) for hospice patients, under specific conditions. Key provisions include requiring collaborative practice agreements with physicians, limiting Schedule II/hydrocodone prescriptions to 120-hour supplies without refills, and prohibiting APRNs from prescribing for themselves or family members. The law directly affects APRNs and their physician collaborators, aiming to clarify and expand their scope of practice while maintaining safety safeguards.
