Top 25 surgical procedures at ASCs

Ambulatory surgery centers (ASCs) continue to be the focus of healthcare industry leaders seeking to reduce overall care costs. The expansion of care delivery outside of the traditional hospital setting correlates with falling costs, improved outcomes, and increased rates of patient satisfaction. Because of their limited offerings and outpatient focus, ASCs can offer diagnostic and outpatient procedures at lower rates than hospitals and other inpatient centers—and often with shorter wait times for patients.

Using data from the Atlas All-Payor Claims Dataset, we’ve ranked the top ASC procedures by their relative share of procedure volume below.

What are the most common surgical procedures?

According to our data, the most common surgical procedure at ASCs is cataract surgery, representing 6.1% of total ASC procedures. Post-cataract laser surgery also appears on our list, with just under 1% of total procedure share.

Many of the procedures on the list are largely diagnostic and focused on the gastrointestinal (GI) system. Colonoscopies and esophagogastroduodenoscopies take up the second through fifth positions in our rankings, with a combined total of over 6.5 million procedures, or 13.8% of the overall procedure volume. 

In addition to cataract and GI-related procedures, epidural injections are the next most performed procedures. Minimally invasive orthopedic surgeries also appear several times among the top 25 procedures.

These trends reinforce the role of specialty surgery centers in healthcare delivery, highlighting the value of affordable and effective care that does not require overnight observation or hospitalization.
