Can a medical assistant give injections in Washington?

The rest of what Washington says on this

Every other rule we have verified under physician supervision & delegation, each linked to its primary source.

• Using a laser, noncoherent light, intense pulsed light, radiofrequency or plasma device that topically penetrates skin and alters human tissue — an “LLRP device”, and one the FDA classifies as a prescription device — IS THE PRACTICE OF MEDICINE under RCW 18.71.011. Washington settles the threshold question in the rule itself rather than leaving it to be argued.

  Wash. Admin. Code 246-919-605(1) and (2) · verified Sep 2, 2026

• ⚠️ AND ANY OTHER ENERGY DEVICE THAT PENETRATES TISSUE IS SURGERY. Use of a medical device using any form of energy to penetrate or alter human tissue for a purpose other than the topical one defined above constitutes SURGERY and is outside this rule entirely — which means outside everything the rule permits a physician to delegate.

  Wash. Admin. Code 246-919-605(3) · verified Sep 2, 2026

• A physician may delegate LLRP treatment to a supervised professional whose own scope allows it, but only against a WRITTEN OFFICE PROTOCOL carrying seven named elements: the identity of the authorizing physician; the activities, decision criteria and plan the delegate must follow; patient selection criteria; the devices and settings for patients meeting them; how the device is operated and maintained; care and follow-up for complications and emergencies; and the delegate’s documentation and feedback plan.

  Wash. Admin. Code 246-919-605(10)(d) · verified Sep 2, 2026

• ⚠️ THE PHYSICIAN MUST BE ON THE IMMEDIATE PREMISES DURING A PATIENT’S INITIAL TREATMENT, able to treat complications, provide consultation or resolve problems. The supervised professional may finish that first treatment only if the physician is called away to an emergency. The delegate must not exercise independent medical judgment, the device may not be used on the globe of the eye, and the treatment may in no way involve surgery.

  Wash. Admin. Code 246-919-605(10)(c), (f) and (g) · verified Sep 2, 2026

• For an ESTABLISHED patient on an existing treatment plan the physician may be temporarily absent — but only with a named local back-up physician who has AGREED IN WRITING to treat complications, who is reachable by phone, and who can SEE THE PATIENT WITHIN SIXTY MINUTES. The absence must be brief and intermittent, and the rule says in terms that it cannot be an ongoing arrangement.

• ⚠️ AND THE ON-SITE ANSWER TURNS ON THE LABEL. If the delegated procedure uses a medication or substance the FDA has NOT approved, or has not approved for the particular purpose it is being used for, the physician MUST BE ON-SITE FOR THE ENTIRE DURATION of the procedure. If it is FDA-approved for that purpose, the physician need not be on site but must be reachable by phone and able to RESPOND WITHIN THIRTY MINUTES to treat complications.

  Wash. Admin. Code 246-919-606(12) and (13) · verified Sep 2, 2026

• Two further limits close the usual workarounds: a physician performing or delegating nonsurgical cosmetic procedures MAY NOT SPONSOR MORE THAN THREE PHYSICIAN ASSISTANTS at any one time, and a physician may not permit a delegate to further delegate the procedure to anyone else. Where the physician is unavailable, an alternate must be arranged who is familiar with the protocols in use, accountable for the supervision, and comparably trained.

• ⚠️ WASHINGTON HAS TWO ESTHETICS LICENSES, AND THE ANSWER DIFFERS BETWEEN THEM. The ordinary “PRACTICE OF ESTHETICS” is surface work — “SUPERFICIAL AND LIGHT PEELS”, “SUPERFICIAL SKIN STIMULATION”, “PORE EXTRACTION”, by any device “EXCEPT LASER” — and it closes with a flat exclusion: “UNDER NO CIRCUMSTANCES DOES THE PRACTICE OF ESTHETICS INCLUDE THE ADMINISTRATION OF INJECTIONS.”

  Wash. Rev. Code § 18.16.020(30) · verified Sep 2, 2026

• ⚠️ AND THE MASTER LICENSE ADDS MEDICAL DEVICES WITHOUT REMOVING THE SUPERVISION QUESTION. “PRACTICE OF MASTER ESTHETICS” adds “MEDIUM DEPTH PEELS AND THE USE OF MEDICAL DEVICES FOR CARE OF THE SKIN AND PERMANENT HAIR REDUCTION” — then says “THE USE OF A MEDICAL DEVICE MUST COMPLY WITH STATE LAW AND RULES, INCLUDING ANY LAWS OR RULES THAT REQUIRE DELEGATION OR SUPERVISION BY A LICENSED HEALTH PROFESSIONAL ACTING WITHIN THE SCOPE OF PRACTICE OF THAT HEALTH PROFESSION.” Holding the master license is therefore not by itself an answer.
