Latest edition issues 733 high performing ratings across four specialties.
WASHINGTON, March 18, 2025 -- U.S. News & World Report, the global authority in hospital rankings and consumer advice, today released the Best Ambulatory Surgery Centers ratings for 2025.
Ambulatory surgery centers (ASCs) provide same-day surgical care for common procedures such as colonoscopies, cataract surgeries, hip/knee replacements and surgical treatment of enlarged prostate.
For the second annual edition of Best Ambulatory Surgery Centers, U.S. News – in collaboration with CareJourney by Arcadia – evaluated 4,357 surgery centers in four separate specialty areas: Colonoscopy & Endoscopy, Ophthalmology, Orthopedics & Spine and Urology.
Ambulatory surgery centers were evaluated based on objective, risk-adjusted measures of their patients' outcomes, including how successfully they avoided complications, ER visits, unplanned hospitalizations and other undesirable outcomes. To ensure fair comparisons among ambulatory surgery centers, the analysis accounted for each patient's pre-existing conditions and other risk factors.
U.S. News recognizes only the highest-rated surgery centers in each specialty that satisfy U.S. News' statistical assessment of performance.
