What shapes anesthesia billing here
California opted out of Medicare's physician supervision requirement for CRNAs in 2009, one of the longer-standing opt-out states. CRNAs working without medical direction can bill Medicare in their own right with the QZ modifier, which makes accurate billing central to an independent group's income.
- Opt-out status: opted out, 2009
- Medicare Part B contractor: Noridian (Jurisdiction E)
- Medicaid program: Medi-Cal
- Employed CRNAs: about 2,600 (BLS, May 2023), plus self-employed and 1099 CRNAs not counted in that figure
