Washington at a glance
What shapes anesthesia billing here
Washington opted out of Medicare's physician supervision requirement for CRNAs in 2003, 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, 2003
- Medicare Part B contractor: Noridian (Jurisdiction F)
- Medicaid program: Apple Health (Washington Medicaid)
- Employed CRNAs: about 660 (BLS, May 2023), plus self-employed and 1099 CRNAs not counted in that figure
