America's Best Ambulatory Surgery Centers 2025

America's Best Ambulatory Surgery Centers 2025

Ambulatory surgery centers continue to play a crucial role in modern health care. In the United States, thousands of these facilities offer colonoscopies, tonsil removals, biopsies, cataract removals, knee repairs, skin grafts and other procedures. According to Definitive Healthcare, there are over 9,000 active ASCs performing millions of procedures each year.

These specialized centers are a popular option for patients seeking safe, quality care outside of a traditional hospital setting. ASCs focus on less invasive surgeries which means nearly 100 percent of admitted patients go home the same day, minimizing both inconvenience and costs.

For a fifth straight year, Newsweek is partnering with global research firm Statista to award America's Best Ambulatory Surgery Centers. This year we've expanded our list to highlight the top 650 ASCs in the country. Over 5,000 ASCs were rigorously evaluated on key criteria including quality of care, patient experience, performance data, and peer recommendations.

We hope our rankings help you make confident and informed decisions when it comes to the health care needs of you and your loved ones.

METHODOLOGY

The 5th edition of America's Best Ambulatory Surgery Centers awards the leading 650 ambulatory surgery centers (ASC) in the U.S. based on quality of care, performance data, patient experience, and peer recommendations, relative to in-state competition.

ASCs included operate exclusively for the purpose of providing surgical services to patients not requiring hospitalization and in which the expected duration of services would not exceed 24 hours following an admission.

The 25 states with the most facilities according to the U.S. Centers for Medicare & Medicaid Services (CMS) were surveyed individually. The remaining states were grouped into 4 regions: Northeast, Midwest, West, South. ASCs from these states were considered accordingly.

Over 5,000 ASCs were analyzed resulting in a varying number of ASCs awarded per state: California had 118 ASCs awarded, while Mississippi is represented with 5 ASCs.

To create the ranking, a score was calculated for each ASC that was part of the analysis. The total score is based on a National Online Survey, CMS Measures, Patient Experience data and Accreditation data.

National Online Survey - Recommendations and quality assessment from peers

The Reputation Score (45 percent of total score) is based on two sub scores:

• Recommendations (80 percent of reputation score)
• Quality Score (20 percent of reputation score)

1 Recommendation Score:

From June to August 2024, Statista conducted a nationwide online survey among medical professionals (medical doctors/surgeons, registered nurses, nursing assistants, therapists) and staff working in the management/administration in ambulatory surgery centers. The survey was available to medical experts to participate on Newsweek.com. Additionally, participants were invited via e-mail.

Participants were asked to recommend notable ASCs in their respective state. Recommendations for own employer/ambulatory surgery center were not allowed.

Recommendations received different weights depending on the order in which they were given, with the first recommendation being assigned the highest weight. Additionally, the professional experience of the participant was considered.

The recommendation score constitutes 80 percent of the reputation score.

2 Quality Score:

For each recommended ASC participants were asked to rate three quality dimensions on a scale from 1 ("Poor") to 10 ("Excellent").

• Quality of surgical care (e.g., procedure)
• Quality of follow-up care (e.g., physical therapies)
• Management of waiting time (e.g., appointments)

The Quality Score constitutes 20 percent of the reputation score.

CMS Measures Score

The CMS Measures Score (45 percent of total score) is based on publicly available data:

The U.S. Centers for Medicare & Medicaid Services provides quality metrics data on ASCs in the Ambulatory Surgical Center Quality Reporting (ASCQR) Program.

The quality metrics data includes the following nine measures:

• Measure 1: Endoscopy/Polyp Surveillance: Appropriate Follow-up Interval for Normal Colonoscopy in Average Risk Patients
• Measure 2: Cataracts - Improvement in Patient's Visual Function within 90 Days Following Cataract Surgery
• Measure 3: Facility 7-Day Risk-Standardized Hospital Visit Rate after Outpatient Colonoscopy
• Measure 4: Normothermia Outcome
• Measure 5: Unplanned Anterior Vitrectomy
• Measure 6: Hospital Visits after Orthopedic ASC Procedures
• Measure 7: Hospital Visits after Urology ASC Procedures
• Measure 8: COVID-19 Vaccination Coverage Among Health Care Personnel
• Measure 9: Facility-Level 7-Day Hospital Visits after General Surgery Procedures

For a center to receive a CMS Measures Score, it must have reported a minimum of 2 measures within the reporting period. Centers that reported fewer measures did not receive a CMS Measures Score and were rated based on the Reputation Score, Patient Experience Score and Accreditation Score only.

The CMS Measures Score constitutes 45 percent of the total score.

Patient Experience Score

The Patient Experience Score is based on publicly available data:

Data from the Outpatient and Ambulatory Surgery Consumer Assessment of Healthcare Providers and Systems (OAS CAHPS) survey was used to analyze patient experience.

Survey topics associated to patient care and satisfaction included:

• Quality of care
• Cleanliness of the facility
• Communication from staff
• Patient rating of the facility as a whole
• Whether or not the patient would recommend the facility to others

The Patient Experience Score constitutes 7.5 percent of the total score.

Accreditation Score

The Accreditation Association for Ambulatory Health Care (AAAHC) is an organization that provides accreditation services to various types of ambulatory health care facilities in the United States and internationally.

The AAAHC sets standards for and assesses the quality of care provided in outpatient settings, which include facilities where surgeries, procedures, and other health services are performed without the need for an overnight hospital stay.

The following accreditation/certification programs were included into the ranking:

• Ambulatory Accreditation
• Medicare Deemed Status Accreditation
• Advanced Orthopaedic Certification

The AAAHC accreditation constitutes 2.5 percent of the total score.

Disclaimer

The rankings are comprised exclusively of ambulatory surgery centers that are eligible regarding the scope described in this document. The ranking is the result of an elaborate process which, due to the interval of data-collection and analysis, reflects the last 12 months only. Furthermore, events preceding or following the period August 30th, 2023 – August 29th, 2024, and/or pertaining to individual persons affiliated/associated to the facilities were not included in the metrics. As such, the results of this ranking should not be used as the sole source of information for future deliberations.

The information provided in this ranking should be considered in conjunction with other available information about ambulatory surgery centers or, if possible, accompanied by a visit to a facility. The quality of ambulatory surgery centers that are not included in the rankings is not disputed.
