What must the supervising physician actually do in California?

Oversight · part of The Practice Perimeter

For an elective cosmetic laser or IPL procedure performed by a licensed provider, a trained physician must be “immediately available” — reachable without delay and able to direct throughout the procedure.

The rest of what California says on this

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

  • A physician may delegate injectable and laser procedures only to appropriately licensed personnel — registered nurses, nurse practitioners, or physician assistants — under genuine supervision. Unlicensed staff (including medical assistants) and improperly licensed staff (estheticians, cosmetologists, LVNs) may not perform them, regardless of training. A “paper” medical-director arrangement is aiding and abetting the unlicensed practice of medicine.
