Training & certification expected

No state-mandated injector training beyond licensure; however, facility protocols and physician delegation agreements typically require documented training.

The license that lets you inject

MD, DO, NP, PA, RN under physician supervision/delegation

If you’re an RN

Yes, under physician delegation and direct supervision; must work in facility with supervising physician present or on-site

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

Verify physician ownership or establish compliant MSO with physician control; confirm on-site supervising physician availability for all injection days.
