What must the supervising physician actually do in California?
Oversight · part of The Practice Perimeter
Short answer
Be immediately available — a physician with relevant laser/IPL training must be reachable by phone or electronically without delay, interruptible, and able to give assistance and direction throughout and cover post-procedure care, per the written protocols.
Whenever an elective cosmetic procedure involving a laser or intense pulse light device is performed by a licensed health care provider acting within the scope of their license, a physician with relevant training and expertise shall be immediately available — defined in the rule as contactable by electronic or telephonic means without delay, interruptible, and able to furnish assistance and direction throughout the procedure and to inform the patient of post-procedure care provisions. Those provisions must sit in the provider’s standardized procedures or protocols.

California does NOT require the supervising physician to be in the building, and the Medical Board says so in terms for physician assistants: physicians must be in the facility with the PA OR be immediately available by electronic communication where the PA works under a delegation of services agreement. The Board pairs that with a hard cap — a physician may supervise only FOUR physician assistants at any given time.

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.
