Does a med spa in Wisconsin need a medical director?

Oversight · part of The Practice Perimeter

Short answer
Not directly — Wisconsin has no med spa license and names no "medical director," but every delegated medical act needs a supervising physician who is competent to perform it and has reasonable evidence the person doing it is competent.

Wisconsin works from both ends. The medical board defines adequate supervision as a two-sided competence test — the physician must be competent to do the delegated act, and must have reasonable evidence the delegate is minimally competent to do it — and failing to supervise adequately is unprofessional conduct, expressly including delegation to UNLICENSED personnel. The cosmetology board comes at it from the other side and names procedures: microneedling is listed as a delegated medical procedure, alongside a catch-all for any treatment reaching below the stratum corneum, so an esthetician may perform it only under a physician’s direction.

  • “Adequate supervision” is defined as a two-sided competence test: a physician should be competent to perform the delegated medical act, and must have reasonable evidence that the supervised individual is minimally competent to perform the act under the circumstances. Both halves have to hold — a competent delegate supervised by a physician who could not do the procedure themselves does not satisfy it.

  • ⚠️ and failing it is unprofessional conduct by name. “Failure to adequately supervise delegated medical acts performed by licensed or unlicensed personnel” is listed as unprofessional conduct. Wisconsin does not restrict delegation to licensed people; it makes the supervising physician answerable for whoever performs the act.
