Top 20 hospitals by total surgeries
The U.S. has thousands of hospitals and health centers across all 50 states. While many of these hospitals specialize in certain types of care, the vast majority perform general surgeries of some form every day.
Using Definitive Healthcare’s HospitalView product, we created a list of U.S. hospitals ranked by the estimated total number of annual surgeries they performed. Total surgery volumes are estimated from the Medicare Standard Analytical Files (SAFs), the hospital’s payor mix, and proprietary research. The figures represent an estimated annual surgical volume for both inpatient and outpatient procedures.
Why surgical volume matters for healthcare commercial strategy
Surgical volume is a key indicator of hospital scale, clinical specialization, and procedural demand. For healthcare commercial teams, understanding which hospitals perform the highest number of total surgeries helps identify high-value accounts, prioritize outreach, and align offerings with procedural intensity.

Which hospitals perform the most surgeries?
The U.S. hospital that performed the most procedures in 2025 is Prisma Health Patewood Hospital in Greenville, South Carolina, with an estimated 343,820 annual surgeries. In second place among hospitals with the most procedures is Covenant Children’s Hospital in Lubbock, Texas. This hospital is estimated to have performed 314,345 surgeries in 2025.

What are the most commonly performed surgeries in the U.S.?
In 2024, the most common inpatient surgical procedure was ICD-10 code 02HV33Z. This cardiac procedure involves the insertion of a central catheter that ultimately terminates the patient’s superior vena cava, a large, valveless vein that pumps deoxygenated blood from the upper half of the body and returns it to the right atrium.
The most common outpatient procedure in 2024 was CPT code 43239, esophagogastroduodenoscopy. This procedure involves inserting a flexible scope down the esophagus to examine upper digestive tract and collect a biopsy.
What’s the difference between inpatient and outpatient surgical procedures?
Inpatient surgeries are performed in a hospital setting, and patients typically stay there for at least one night after the procedure. Outpatient surgeries, also known as same-day or ambulatory surgeries, may be performed in a surgical center or hospital, but the patient is discharged on the same day.
