Choosing an Ambulatory Surgery Center
Official CMS quality and patient-experience data

Compare ambulatory surgery centers.

Choose the planned procedure and as many as three Medicare-certified ambulatory surgery centers. The report organizes available CMS safety, procedure-related hospital-visit, and OAS CAHPS patient-experience information.

Confirm that outpatient surgery is appropriate for you. The surgeon and anesthesia professional should consider your health, procedure, expected recovery, and access to emergency care. In an emergency, call 911 or seek immediate care.

1. Describe the procedure

CMS has procedure-specific measures for selected categories. Other procedures may receive a gray signal because a comparable CMS outcome is unavailable.

2. Select the exact centers

Search by facility name, city, ZIP code, or CMS facility ID.

No overall CMS star: CMS does not assign ambulatory surgery centers an overall 1–5 quality star comparable to hospitals or nursing homes. The colored shape is created by this guide from selected public measures and must be read with its explanation.

How to read the signal

A missing or suppressed result never supports green. A center may perform a procedure even when CMS cannot report a procedure-specific result.
