Relating to the prescribing and ordering of Schedule II controlled substances in a narcotic drug treatment program by certain advanced practice registered nurses and physician assistants.

HB 5533 permits advanced practice registered nurses (APRNs) and physician assistants (PAs) to prescribe and order Schedule II controlled substances (such as opioids used in medication-assisted treatment) within certified narcotic drug treatment programs. This requires physicians to delegate prescribing authority, and applies only to programs holding a valid permit under Texas Health and Safety Code Chapter 466. The bill specifically expands provider roles in opioid use disorder treatment programs, not general medical practice. It does not change existing delegation rules for hospital settings or hospice care.
