CRNA scope of practice — state by state (2026)
Most states allow CRNAs to practice independently. Some don't. Here's the actual map for 2026.
TL;DR
Following the 2001 federal Medicare opt-out provision, governors of US states can elect to remove the physician-supervision requirement for CRNAs at state level. As of 2026, 24 states + Guam have opted out (independent CRNA practice). The remaining states still require some level of physician supervision, though the practical scope varies significantly within those rules.
What 'opt-out' actually means
The Medicare physician-supervision rule (42 CFR 482.52) requires that anesthesia services in hospitals be supervised by an operating practitioner or anesthesiologist for Medicare reimbursement. In 2001, the rule was amended to allow state governors to opt their state out of the federal supervision requirement. Opt-out states recognize CRNAs as fully independent providers for Medicare patients. State practice acts may still impose additional requirements on top.
Opt-out states (independent CRNA practice for Medicare)
As of 2026, 24 states + Guam have opted out: Iowa (first, 2001), Nebraska, Idaho, Minnesota, New Hampshire, New Mexico, Kansas, North Dakota, Washington, Alaska, Oregon, Montana, South Dakota, Wisconsin, California (limited), Colorado, Kentucky, Guam, Arizona, Michigan, Tennessee, Mississippi, Virginia, plus a few others added in the 2020s. Several states are mid-opt-out process. Always check the AANA's current state-by-state tracker before making career decisions based on this.
Independent practice doesn't mean unsupervised in EVERY way
Even in opt-out states, individual hospitals/facilities can impose their own internal supervision policies. State practice acts may require collaborative-agreement language, written protocols, or specific procedures (e.g., regional anesthesia, chronic pain, propofol-for-sedation) to require additional credentialing. Federal facilities (VA, IHS, DoD) have always recognized CRNAs as independent providers regardless of state.
Prescribing authority — separate from anesthesia supervision
Most states grant CRNAs prescribing authority for controlled substances within the scope of anesthesia practice — pre/post-op pain meds, anesthetic agents, antiemetics. A few states limit Schedule II prescribing or require collaborative-physician sign-off. State controlled-substance licensing is separate from the federal DEA registration; both are required.

Practice authority drives compensation indirectly through market dynamics. In opt-out states with broad scope, CRNAs can work in independent groups, rural hospitals without staff anesthesiologists, OB centers, ASCs, and pain clinics. Compensation tends to be 10-20% higher and locum opportunities richer. In supervision-required states, CRNAs typically work in care-team models inside larger groups — still well-compensated, just less practice-flexibility.
Career strategies by state type
Opt-out state, considering it long-term: lean into independent practice, owner-operator opportunities, locum portfolio. Supervision-required state, want flexibility: get credentialed in an adjacent opt-out state too — many CRNAs hold multiple state licenses for travel/locum. Federal-friendly state: VA + DoD positions offer the same scope nationwide regardless of state law, with federal benefits + loan repayment.
How scope changes — political reality
Scope expansion is hospital-by-hospital + state-by-state political work. AANA + state CRNA associations lobby for opt-out and broader practice authority. Push-back typically comes from state medical societies. The 2020s have seen 5+ states opt-out post-COVID, when temporary scope expansions during the public-health emergency demonstrated CRNA independence is safe.
