Top 10 procedures performed at surgery centers
As medical technology advances and guidelines for routine inpatient surgeries relax, physicians can perform more procedures in an outpatient care setting. This shift in care is often beneficial for patients, as procedural costs at an ambulatory surgery center (ASC) are sometimes lower than at a hospital or other inpatient facility.
While most hospitals offer outpatient surgery or ambulatory surgery options, ASCs have been praised as a superior choice for certain procedures. This preference is largely due to facility efficiencies and greater regulatory controls for reimbursements under the outpatient prospective payment system.
Definitive Healthcare tracks nearly 3,000 procedure types performed at more than 11,000 ASCs. The following lists rank the top 10 procedures performed at surgery centers by procedure volume and total charges.

What is the most commonly performed procedure at an ASC?
It’s important to note that the most recent data are from the 2019 calendar year because of the COVID-19 pandemic.
In 2019, CPT code J1095—injection, dexamethasone 9%—was the most performed ambulatory surgery center procedure, with more than 1.7 million total procedures reported. Code C9290, injection, bupivacaine liposome and code 66984, extracapsular cataract removal W/O ECP were the second and third most performed procedures, with 1,272,025 and 1,262,068 total procedures reported, respectively.
A few of the most common outpatient procedures are diagnostic procedures of the gastrointestinal (GI) system, such as colonoscopies and esophagogastroduodenoscopies (EGD). These procedure types appeared three times on this list, with a combined total of more than 1.4 million total procedures in 2019.
Cataract-related surgeries also topped this list, with more than 1.5 million procedures reported in 2019.
In addition to cataract and GI-related procedures, epidural injections are also commonly performed procedures. This trend is consistent with the role of ASCs in healthcare delivery, which is to offer affordable and effective care that does not require overnight observation or other hospitalization.
The following list details the top 10 procedures performed at ASCs by total charges.

What is outpatient surgery?
Outpatient surgery refers to medical procedures that healthcare providers perform in outpatient settings like ASCs. Patients having outpatient surgery do not need to stay overnight in the hospitals or other inpatient settings.
