Collaborative Practice Agreement for Certified Nurse-Midwives in Arizona
No. Certified Nurse-Midwives practice independently here. Arizona does not require one.
A.R.S. § 32-1601 defines CNM scope in parallel with general NP — diagnosing and prescribing (including controlled substances) within CNM scope, with only a professional consult/refer standard and no collaborative-agreement mandate. A dedicated numbered CNM scope statute beyond §§ 32-1601/32-1636 was not located in this research pass.

About Arizona's rules
Arizona has no explicit statutory CPOM ban; existing doctrine comes only from two optometry cases never applied to physician/PA ownership, making MSO tolerance a reasonable inference rather than a confirmed rule. NP/CNM/PMHNP have FULL practice authority with no collaborative agreement. PA's 2024 reform (A.R.S. Title 32 Ch. 25) removes the written agreement at 8,000 hours but still requires a designated collaborating physician/entity.
