Training & certification expected
No state-mandated injector training beyond licensure; however, physician supervision and facility protocols typically require documented training.
The license that lets you inject
MD, DO, NP, PA, RN under physician supervision
If you’re an RN
Yes, under physician supervision and delegation; must work in facility with supervising physician present or on-call
Why the order still matters
Required; in-person exam mandatory before treatment Training gets you the skill; a valid order or good-faith exam is what keeps the treatment lawful.
What to verify in California
Ensure a California-licensed physician is the controlling owner or medical director with clear supervisory authority over all injectors.
