Can CAAs practice in Michigan?
Yes — CAAs practice in Michigan under physician delegation.
Michigan has no AA license yet; CAAs practice under physician delegation authority in the Public Health Code (MCL 333.16215), always under a supervising anesthesiologist. Licensure bills SB 428 and HB 4832 were introduced in 2025 and remained in committee as of mid-2026.

- Supervision
- A supervising physician (anesthesiologist) delegates under MCL 333.16215, which allows a licensee to delegate acts within the scope of the licensee's practice to a qualified licensed or unlicensed individual performed under the licensee's supervision; no AA-specific statutory ratio in current law.

Notes
Verified that neither HB 4832 nor SB 428 has passed either chamber (some aggregator summaries misleadingly imply passage; action histories show both bills sitting in committee). HB 4832 as introduced would cap an anesthesiologist at supervising 4 CAAs concurrently and protect the 'C.A.A.' title from Aug. 1, 2026 — proposed language only, not current law.
