Can a physician assistant inject or prescribe in Washington?
Who treats · part of The Practice Perimeter
Short answer
Yes for injecting — a physician may delegate nonsurgical cosmetic procedures to a properly trained PA, and a PA may use an LLRP device with a participating physician's consent and required training. The cited rules do not settle PA prescribing authority.
A physician assistant may use an LLRP device on skin with the consent of a participating physician and in accordance with standard medical practice, provided they are appropriately trained in the physics, safety and techniques of the device beforehand and remain competent for as long as it is used. Washington gives physician assistants their own rule rather than treating them as a delegate under the physician’s.

A physician assistant carries the same pre-treatment duties a physician does — history, appropriate physical examination, diagnosis, recommended treatment, informed consent INCLUDING telling the patient a nonphysician may operate the device, emergency and follow-up instructions, and an appropriate medical record — and may themselves delegate an LLRP procedure onward to a properly trained licensed professional whose own scope allows it, so long as it involves no surgery and the device is not used on the globe of the eye.

Registered nursing practice expressly includes the executing of a medical regimen as prescribed by a licensed physician and surgeon, osteopathic physician, podiatric physician, dentist, physician assistant or advanced registered nurse practitioner. The order may come from any of those; the nurse carrying it out is acting on it.

← All Washington rules and changes · MedSpaRadar is regulatory monitoring and reference: it summarizes public laws, regulations and agency actions and links each to its source. It is not legal, medical, or compliance advice, and using it creates no attorney-client relationship. A summary can lag its source or leave out detail, and monitoring itself can be interrupted — so an absence of alerts means nothing reached you, not that nothing happened.
