Do You Need a Medical Director for a Med Spa in Massachusetts?

Whether Massachusetts requires a medical director — and what that director is actually on the hook for — shapes your staffing, your liability, and your startup budget. Here's the Massachusetts picture.

By Evan at Inside MedSpa

Medical director requirement

Required; physician must be on-site or immediately available

Corporate Practice of Medicine

Strict; physician ownership or direct control required 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 cannot inject neurotoxins/fillers; limited to supportive roles

How the exam ties in

Required; in-person exam mandatory before treatment

What to verify in Massachusetts

Ensure a licensed MD or DO is the owner or has controlling interest, and verify on-site physician availability for all injection services.
