The same question, answered for 5states from each state’s own law. States disagree on this, which is the point — an answer that is right in one is wrong next door. Every entry below is a statute or board rule we verified, most recently Aug 17, 2026.

Arizona

A registered nurse practitioner may diagnose and may prescribe, administer, and dispense legend drugs and devices within the NP scope — so an NP may both order and administer cosmetic injectables.

California

Under standardized procedures, an NP (unlike an RN) may be delegated the prior good-faith exam and the ordering of the drug or device. AB 890’s autonomous-NP categories do not carve out or specially authorize aesthetic practice, and an autonomous NP remains bound by the good-faith-exam and CPOM rules.

New York

A certified nurse practitioner may diagnose illness and physical conditions and perform therapeutic and corrective measures within a specialty area, in collaboration with a physician qualified to collaborate in that specialty, under a written practice agreement and written practice protocols. Where the agreement does not resolve a disagreement over diagnosis or treatment, the collaborating physician’s view prevails.

Which states this covers

5 of the 6 states for which we publish statute-cited rules. That is not every state, and nothing above should be read as describing one that is not listed — the answer genuinely differs, so a neighbouring state is not a guide. We monitor all 50 state legislatures plus the FDA and the Federal Register daily; the cited rule set is narrower than the monitoring and is growing on its own timetable.
