Medical director requirement
Required for medical spa operations
Corporate Practice of Medicine
Lenient; MSO/management structures permitted This is the doctrine that decides whether a non-physician can own or control the practice, and it usually travels hand-in-hand with the medical-director question.
Who can supervise or delegate
NP/PA may inject under physician collaboration; independent practice limited
How the exam ties in
Required; in-person or telehealth allowed under physician discretion
What to verify in Washington
