Michigan Compiled Laws, Chapter 333. Health § 333.20727

(a) Professionally recognized standards of practice based on standards issued by the American Association of Birth Centers, the American College of Nurse-Midwives, and the National Association of Certified Professional Midwives. If any of the standards described in this subdivision are revised after the effective date of the amendatory act that added this section, the department shall take notice of the revision. The department, in consultation with the persons described in this section, may promulgate rules to incorporate any revision by reference.

(b) Limiting factors that, when present, would preclude a patient from delivering at the freestanding birth center because the patient is not considered to be a patient with a normal delivery. The rules must allow a freestanding birth center to develop policies that would include additional limiting factors to preclude delivery at the freestanding birth center.
