Contracts
If you’re a CRNA, you already know how important it is to stay current on changing policies, practice rights, and industry trends. But one thing that can have a massive impact on your earning power and work flexibility? Knowing where you can legally practice independently without physician supervision.
Your education and clinical skills don’t change from state to state. But your freedom to use them to their fullest potential absolutely does. As of 2025, over two dozen states have formally given CRNAs the green light to practice without a physician's sign-off, and that shift has real implications for your career.
Let’s break down what independent practice means, which states support it, and how it could open the door to better contracts, more autonomy, and higher earning potential.
What “Independent Practice” Really Means for CRNAs
CRNAs are already recognized by Medicare as advanced practice providers. However, unless a state has officially “opted out” of the federal supervision requirement, Medicare still expects CRNAs to work under a physician's supervision for billing purposes. That rule doesn’t reflect your capability, just the paperwork.
When a state opts out, it's informing CMS that CRNAs in that state can practice without mandatory physician oversight for Medicare reimbursement. In practical terms, that means you may:
- Bill for your services directly
- Negotiate higher pay
- Work in rural and underserved facilities without a supervising physician
- Make care decisions more autonomously
And in certain settings like outpatient surgery centers or critical access hospitals, this kind of independence isn’t just convenient it’s essential.
Opt-Out States in 2025
As of this year, 25 states have opted out of the federal physician supervision requirements for CRNAs:
Opt-Out States:
Alaska, Arizona, Arkansas, California, Colorado, Delaware, Idaho, Iowa, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Utah (partial), Washington, Wisconsin, Wyoming (partial).
Opt-Out States:
Alaska, Arizona, Arkansas, California, Colorado, Delaware, Idaho, Iowa, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, Montana, Nebraska, New Hampshire, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Utah (partial), Washington, Wisconsin, Wyoming (partial).
Note: State law isn’t the only hurdle even in opt-out states, some hospitals or health systems maintain internal policies that still require physician oversight. Always verify facility bylaws and credentialing rules.
Why This Matters: Pay, Autonomy, and Career Options
Practicing independently gives you more freedom than it gives you leverage. In opt-out states, CRNAs often negotiate better pay, since Medicare doesn’t split reimbursement with supervising physicians. You also have more control over your schedule, clinical decisions, and practice model. This is particularly true if you join a private group or contract directly with a facility.
Independent CRNAs in many of these states are forming LLCs or group practices, allowing them to:
- Bill under their own NPI
- Take on W-9 contractor roles with tax-deductible business expenses (malpractice insurance, CME, etc.)
- Serve as the sole anesthesia provider in certain hospitals or ASCs
In rural areas with workforce shortages, some CRNAs even found mobile anesthesia services, contracting with multiple facilities while earning $200–$250/hour or more.
Reimbursement and How It Changes with Independence
Under the medically directed model, Medicare typically splits payment: 50% to the CRNA, 50% to the physician. But if you're operating independently in an opt-out state, you’re eligible to receive 100% of the reimbursement for covered services.
That adds up quickly, especially if you’re working on high-volume cases or contracting with ASCs that rely on CRNAs as sole providers. Some private insurers even offer higher per-case reimbursement to CRNAs in independent roles, particularly in pain management and GI specialties.
Keep in mind:
- Medicaid policy doesn’t always align with CMS opt-out status — some states still require collaboration to bill.
- In partial opt-out states (like Utah and Wyoming), independent practice may be limited to rural areas or certain facility types.
- Some facilities still require an “anesthesia medical director” to co-sign credentialing files, even when it’s not legally required.
Future Mobility & Practice Expansion
- A CRNA-specific compact license still doesn’t exist, but APRN Compact discussions are underway in several states. Keep an eye on AANA updates.
- Medicare is reviewing language around supervision in its payment rules. Future revisions could further open the door to full federal recognition of CRNA autonomy.
Independent practice isn’t just about working without supervision, it’s about fully owning your expertise, expanding your career options, and maximizing your earning potential. Whether you're considering a move, negotiating a new contract, or thinking about branching out on your own, understanding where you can practice independently is key to making informed, empowered decisions.
In a healthcare landscape that continues to evolve, your ability to practice at the top of your license has never mattered more. Staying informed about practice laws, facility policies, and billing structures isn’t just smart, it’s strategic. Your training qualifies you. Knowing where and how to use it sets you apart.
