What are CRNAs and why Is demand on the rise?
Certified Registered Nurse Anesthetists (CRNAs) are advanced practice nurses trained to provide anesthesia and pain management services in a wide variety of healthcare settings. From bustling urban hospitals to the most remote rural clinics, CRNAs deliver high-quality anesthesia care—often serving as the sole anesthesia provider in less-populated areas.
Why are so many healthcare systems scrambling to hire more CRNAs? There are a few reasons.
- Aging Population: As the baby boomer generation ages, the need for surgeries and procedures requiring anesthesia is climbing steadily.
- Preventive Care Expansion: Improved access to preventive care and outpatient procedures means more opportunities for CRNAs to step in.
- Critical Rural Role: In rural communities, CRNAs often represent more than 80% of all anesthesia providers, keeping these hospitals and surgical centers running.
- Projected Growth: The U.S. Bureau of Labor Statistics anticipates a 10% jump in CRNA employment by 2033—outpacing many other healthcare roles.
In short, CRNAs are not only essential—they’re in demand like never before, especially in locations where access to physician anesthesiologists is limited.
Practicing as a CRNA
Each year, CRNAs administer over 50 million anesthetics in the United States, serving as a backbone of anesthesia care nationwide. Roughly one-third of U.S. hospitals and more than two-thirds of rural hospitals rely exclusively on CRNAs for anesthesia services.
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.
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
In certain settings like outpatient surgery centers or critical access hospitals, this kind of independence isn’t just convenient, it’s essential.
Why some CRNAs flourish with independence while others value support
Seasoned CRNAs often find independent practice appealing—and for good reason. The ability to shape your own clinical decisions, take on a broader mix of case types, and walk into each shift knowing you’re calling the shots has its rewards. For many experienced clinicians, this autonomy isn’t just liberating; it’s an opportunity to apply their full range of skills and truly influence patient care, especially in fast-paced environments like surgery centers or critical access hospitals, where flexibility is key.
Of course, everyone’s learning curve looks different. Newer graduates might prefer the safety net of physician supervision as they build confidence and accumulate hours at the head of the table. With an extra set of eyes, they’re able to ease into tricky cases and focus on learning, rather than navigating everything solo from day one. In fact, many early-career CRNAs intentionally seek out collaborative environments—at least until routine turns into second nature.
This balance between autonomy and support isn’t about one path being “better”—it’s about matching your practice setting to your experience level, comfort zone, and career goals.
Opt-out states for CRNAs
As of this year, 25 states have opted out of the federal physician supervision requirements for CRNAs.
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.
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
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.
Final thoughts
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.

Do CRNAs earn more in independent practice states?
Many CRNAs in opt out states report higher earning potential because they can take on broader responsibilities and additional procedures. Market demand, rural need, and facility type also influence income.
Does CRNA malpractice coverage differ in independent practice?
Coverage requirements may increase when practicing independently. Many CRNAs carry individual policies to ensure sufficient protection.
