certificates of necessity; exemption

HB 2661 is a procedural bill that amends definitions in Arizona's emergency medical services statutes. It updates specific terms like "certificate of necessity," "ambulance attendant," and "advanced life support" without creating new requirements or exemptions. The bill solely clarifies existing terminology within Chapter 36 of the Arizona Revised Statutes, affecting how emergency medical services are formally described in state law. It does not directly impact providers, patients, or new policy implementation. (Note: As a definitional amendment, this is a procedural change with no substantive policy effect.)
