ASC Surgical Tech Salary 2026: $60,280/yr (BLS)
Ambulatory surgical centers are the fastest-growing employment segment in US surgical technology, driven by the CMS-led migration of joint replacement, GI, ophthalmic, and select cardiac cases from inpatient hospital settings to outpatient venues. ASC staff CST pay sits slightly below hospital pay, but schedule predictability (no nights, weekends, or call) and IC opportunity for CSFAs make ASCs one of the most attractive surgical tech employment categories for many career stages.
The ASC surgical tech environment
Ambulatory surgical centers are freestanding outpatient surgical facilities licensed and regulated separately from hospital operating rooms. ASCs perform elective surgical procedures on a same-day basis, with patients arriving the morning of surgery and discharging the same day. ASC case mix is structurally constrained to procedures that can be safely performed on an outpatient basis: orthopedic joint replacement (since the 2018 and 2020 CMS site-of-service updates), arthroscopy, GI endoscopy, ophthalmology (cataract surgery is by far the most common single ASC case nationally), gynecology, urology, ear, nose, and throat, and select cardiac and vascular work.
The defining feature of ASC employment from a surgical tech perspective is schedule predictability. ASC operating hours are typically weekday-only, daytime-only (often 0700 to 1530 or 0730 to 1700 with case-finishing flexibility). There is no overnight coverage, no weekend coverage, no holiday coverage, and no on-call requirement. The case schedule is set days or weeks in advance, with limited last-minute schedule changes compared with hospital ORs. For surgical techs prioritizing work-life balance, predictability, and the ability to plan around family or other commitments, the ASC setting is structurally favorable.
ASC employer ownership structure varies. The four largest national ASC operators are United Surgical Partners International (USPI, a Tenet Healthcare subsidiary), Surgery Partners, AmSurg, and SurgCenter, with hundreds of facilities between them. Physician-owned single-specialty ASCs (typically owned by the surgeons who use them) are common particularly in orthopedic, gastroenterology, ophthalmology, and pain medicine. Hospital-affiliated ASCs (owned by hospital systems and integrated with hospital operations) are also significant. Each ownership structure has different implications for staff CST pay and benefits.
ASC case volume per OR is typically high. A well-run ASC OR running cataract surgery might complete 15 to 20 cases in a day. An orthopedic ASC OR running outpatient knee or hip replacement might complete 5 to 8 cases per day. A GI ASC running endoscopy might complete 20 to 25 cases per day. The high case volume per OR creates consistent demand on the tech across the entire day, which differs from the hospital OR case rhythm of one or two longer complex cases. ASC techs report that the case throughput rhythm is its own learned skill that takes some adjustment for techs transitioning from a hospital setting.
The IC CSFA opportunity at orthopedic ASCs
Independent contractor first assistant work at orthopedic ASCs is the highest-paying non-prescribing career path in surgical technology and is concentrated in the ASC setting. The structure is straightforward: a CSFA (Certified Surgical First Assistant) credentialed by NBSTSA contracts with one or more orthopedic surgeons to provide first-assist services on a per-case basis. The CSFA invoices the surgeon (or, depending on the arrangement, the patient or an insurance billing service) at hourly rates of $50 to $65 per hour. At a busy outpatient orthopedic ASC running 6 to 10 cases per day, a CSFA who works full-time across one or more surgeon practices can generate billing of $110,000 to $140,000 annually.
The IC CSFA model has several practical implications. The CSFA is self-employed and responsible for their own taxes (including the employer-side payroll tax that is otherwise covered by W-2 employers), malpractice insurance, retirement saving, and health insurance. The administrative overhead is meaningful and most successful IC CSFAs either manage their own books or contract with a small healthcare-focused accounting and billing service. Income is variable, depending on surgeon practice volume, case mix, and the contractor's reputation for reliability and case-flow expertise.
The IC CSFA opportunity is concentrated at high-volume single-specialty orthopedic ASCs and at private plastic surgery ASCs. Multi-specialty ASCs typically employ staff CSFAs rather than contracting with ICs. Hospital-affiliated ASCs generally do not use the IC model. For surgical techs whose career goal is the highest non-prescribing income tier in the field, the path is CST first, then 5 to 10 years hospital orthopedic experience, then CSFA program, then transition to IC work at a high-volume orthopedic ASC. The total runway is meaningful but the income outcome at the end is the highest in the field.
ASC site-of-service migration and outlook
The growth of US surgical case volume performed in ASCs has been one of the most consequential trends in surgical employment over the past decade. CMS removed total knee replacement from the inpatient-only list in 2018 and total hip replacement in 2020, opening reimbursement pathways for outpatient performance of these procedures. Industry analysts estimate that the share of total knee and hip replacements performed in outpatient ASCs has grown from less than 5 percent in 2018 to a meaningful fraction by 2026, with continued growth projected through the decade.
Beyond orthopedic joint replacement, GI endoscopy was already heavily outpatient and continues to consolidate at ASC facilities. Cataract surgery is essentially all ASC-based at this point, with the small remaining hospital-based volume mostly representing patients with complex co-morbidities. Pain medicine procedures have substantially migrated to outpatient ASC settings. Plastic surgery has been ASC-dominant for aesthetic procedures throughout. Select cardiac procedures (particularly some ablation work) have begun to migrate to ASC settings as reimbursement and patient-safety standards have evolved.
For surgical technologists, the ASC site-of-service migration creates sustained employment growth in the setting. Techs with orthopedic, GI, ophthalmology, or specialty surgical experience are positioned for strong ASC job markets through the late 2020s. The ongoing growth of physician-owned and private-equity-backed ASC chains adds further employment opportunity, with USPI, Surgery Partners, AmSurg, and SurgCenter all in active national hiring for both staff CST and IC CSFA talent. The combination of growth trend, lifestyle predictability, and IC ceiling makes ASC employment one of the most defensible long-term career bets in surgical technology.
