Question 1

What is an ambulatory surgery center (ASC)?

Accepted Answer

An ambulatory surgery center is a licensed medical facility where patients have elective surgical or diagnostic procedures performed and go home the same day. ASCs are freestanding outpatient facilities separate from hospitals, specializing in procedures across more than 20 surgical specialties.

Question 2

What quality metrics are included in your directory?

Accepted Answer

We include CMS-verified quality measures including OAS CAHPS patient experience scores, Medicare certification status, accreditation body (AAAHC, AAAASF, Joint Commission), Google reviews and ratings, ownership type, specialties offered, and operating room count.

Question 3

How many ambulatory surgery centers are in your directory?

Accepted Answer

Our directory includes over 5,700 Medicare-certified ambulatory surgery centers nationwide, covering all 50 states. All listed facilities meet federal Conditions for Coverage.

Question 4

Does Medicare cover outpatient surgery at an ASC?

Accepted Answer

Yes. Medicare Part B covers outpatient surgery at Medicare-certified ASCs. Medicare pays the facility a fixed ASC rate, which is typically 45-60% less than a hospital outpatient department for the same procedure. Patients are responsible for the Part B deductible and 20% coinsurance.

Question 5

How are ASCs accredited?

Accepted Answer

ASC accreditation is voluntary and provided by three major organizations: AAAHC (Accreditation Association for Ambulatory Health Care), AAAASF (American Association for Accreditation of Ambulatory Surgery Facilities), and The Joint Commission. Accredited facilities have undergone rigorous independent inspection beyond what Medicare certification requires.
