A registered nurse first assistant, or RNFA, is a perioperative registered nurse with advanced surgical training who works directly alongside the surgeon during operations. Unlike other operating room nurses who manage instruments or monitor patients from the periphery, the RNFA scrubs in and actively participates in the procedure itself: retracting tissue, controlling bleeding, suturing wounds, and helping close surgical sites. It’s one of the most hands-on roles a nurse can hold in the operating room.
What an RNFA Does During Surgery
The RNFA functions as a direct extension of the surgeon. Their intraoperative responsibilities include using surgical instruments and medical devices, providing exposure of the surgical site so the surgeon can see and access the area clearly, handling and cutting tissue, achieving hemostasis (stopping bleeding), suturing, and managing the wound. These are tasks that go well beyond what a standard circulating nurse or scrub nurse performs.
Before the first incision, the RNFA helps with patient positioning, ensuring the person on the table is placed in a way that gives the surgeon optimal access while keeping the patient safe. After the procedure, they may apply dressings or bandages, participate in postoperative rounds, and assist with discharge planning, including connecting patients with community resources for recovery. The role spans the entire surgical episode, not just the time between cut and close.
How an RNFA Differs From a Surgical Technologist
Surgical technologists and RNFAs both work in the operating room, but their responsibilities are quite different. A surgical technologist focuses on preparing instruments, passing them to the surgeon, and maintaining the sterile field. They keep the environment organized and ready, but they don’t typically perform hands-on surgical tasks on the patient.
An RNFA, by contrast, retracts tissues to improve the surgeon’s visibility, controls bleeding, sutures incisions, and closes surgical sites with staples or stitches. They also bring a nursing background to the role, meaning they assess the patient’s overall condition and can recognize complications as they develop. The distinction comes down to preparation and proximity: surgical technologists support the environment, while RNFAs support the surgery itself.
Education and Training Requirements
Becoming an RNFA requires a significant investment beyond a standard nursing degree. Candidates must first be licensed registered nurses with perioperative (surgical) nursing experience. From there, they complete a formal RNFA education program that meets standards set by AORN, the Association of periOperative Registered Nurses. These programs are offered through universities and specialty institutions. At the University of Tennessee Health Science Center, for example, the certificate program includes 180 clinical hours precepted by board-certified surgeons, with a 4:1 ratio of clinical and lab hours to credit hours. That means each credit translates to roughly 60 hours of hands-on clinical or lab work, plus an additional 30 hours of preparation.
The clinical training is designed to build competency in both intraoperative surgical assisting and postoperative patient management, so graduates can document and manage care across the full surgical timeline.
Certification as a CRNFA
After completing an RNFA program, many nurses pursue the Certified Registered Nurse First Assistant (CRNFA) credential. The eligibility requirements are specific. You need current CNOR certification (the standard perioperative nursing certification), completion of an approved RNFA program, and a minimum of 2,000 documented hours of practice as an RNFA. Those hours can include preoperative, intraoperative, and postoperative patient care.
Advanced practice registered nurses, such as nurse practitioners, certified nurse-midwives, or nurse anesthetists, can also pursue CRNFA certification. They need a master’s or doctoral degree in an advanced practice program, current APRN certification, and the same 2,000 hours of RNFA practice. There’s no shortcut on the clinical hours regardless of your other credentials.
Scope of Practice Across States
The RNFA role is recognized within the scope of nursing practice by nurse practice acts in all 50 states. That said, the specific rules governing what an RNFA can do, and how they’re reimbursed, vary by state. Some states define RNFA behaviors more broadly than others. If you’re considering this career path, checking with your state board of nursing is worth the effort, since regulations around practice authority and reimbursement language differ enough to affect your day-to-day work.
How RNFAs Are Paid for Their Services
RNFAs bill for their surgical assisting services using specific billing modifiers that indicate someone other than a physician served as the assistant surgeon. Under Medicare, the reimbursement structure is tiered. A physician serving as an assistant at surgery receives up to 16 percent of the Medicare Physician Fee Schedule amount for that procedure. When a nurse practitioner, physician assistant, or clinical nurse specialist serves in that role, the rate drops further to 85 percent of that 16 percent amount.
For context, this means an RNFA’s reimbursement for assisting on a given surgery is roughly 13.6 percent of what the lead surgeon bills for the same procedure under Medicare. Private insurance reimbursement varies, and some facilities pay RNFAs a salary rather than billing per procedure.
Salary and Job Outlook
The Bureau of Labor Statistics does not track RNFAs as a separate category, but the median annual wage for registered nurses overall was $93,600 in May 2024. RNFAs typically earn more than the general nursing median because of their specialized training and the high-stakes nature of surgical assisting. Exact figures vary by employer, region, and whether the RNFA is salaried or billing independently.
Employment of registered nurses is projected to grow 5 percent from 2024 to 2034, which is faster than average for all occupations, with an estimated 166,100 new positions. The demand for surgical services continues to rise as the population ages, which keeps experienced perioperative nurses, and especially those with first assisting credentials, in a strong position in the job market.
