Oklahoma is now the 19th state to opt out from federal regulations that require physician supervision of Certified Registered Nurse Anesthetists (CRNAs). The American Association of Nurse Anesthetists reports that governors of 18 states and Guam have exercised such exemptions prior to the Centers for Medicare & Medicaid Services' (CMS) suspension for all states during the COVID-19 health crisis.
