The U.S. ambulatory surgery center (ASC) market was valued at USD 49.19 billion in 2026 and is projected to grow at a CAGR of 6.15% through 2035. The growth of the market is driven by increasing migration of procedures from hospital outpatient departments to ASCs, growing physician participation, rising demand for cost-efficient outpatient care, favorable reimbursement economics, and advances in minimally invasive and also higher-acuity procedures. Major trends include the expansion of ophthalmic, gastroenterology, orthopedic, ENT, and cardiovascular procedures, alongside greater acceptance of robotic surgery, advanced imaging, digital patient management, as well as enhanced anesthesia technologies. Expanding ASC infrastructure, payer and provider focus on lower-cost sites of care, and continued consolidation via acquisitions and joint ventures are anticipated to create new opportunities for ASC operators, technology vendors, healthcare providers, and investors through 2035.
