Relating to the authority of a physician to supervise or delegate the prescribing or ordering of a drug or device to a physician assistant or advanced practice registered nurse.

HB 3890 modifies Texas law to restrict when physicians can delegate prescribing authority to physician assistants (PAs) or advanced practice registered nurses (APRNs). It prohibits physicians from delegating drug or device prescribing to PAs or APRNs practicing in a specialty outside the physician’s training or primary practice - unless the physician has at least five years of experience in that specialty. This requirement directly affects physicians, PAs, and APRNs by adding a new condition for delegation. The bill takes effect September 1, 2025, and creates a clear, time-bound standard for scope-of-practice delegation.
