The best ASCs for colonoscopy, endoscopy: US News

California and Florida led the nation in top-rated ASCs for colonoscopy and endoscopy, according to U.S. News’ “2026 Best Ambulatory Surgery Centers” published March 17. 

The 2026 U.S. News ratings for ASCs are based on Medicare fee-for-service claims data from 2022 through 2024, analyzed by healthcare analytics firm Arcadia using CMS data systems, with facilities identified through the National Plan and Provider Enumeration System and ASC Quality Reporting program databases — no action was required by facilities to be included. 

The ratings evaluate 17 types of episodes of care grouped into four specialty areas (colonoscopy and endoscopy, ophthalmology, orthopedics and spine, and Urology). Reflecting the generally lower risk of outpatient procedures, the threshold for a “high performing” designation has been expanded to the top 15% of ASCs by composite score, up from approximately the top 10% in prior years.
