Power your team with the highest quality, daily updated intelligence on hospitals, physicians, and other healthcare providers

As medical technology advances and guidelines for routine inpatient surgeries are relaxed, physicians are able to perform a greater number of procedures in an outpatient setting.  

This is generally beneficial for patients, as costs at an ambulatory surgery center (ASC) are lower on average than at a hospital or other inpatient facility. While most hospitals offer outpatient surgery, ASCs have been praised as a superior choice for certain procedures.  This preference is 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 over 9,000 ASCs. The following lists rank the top 25 procedures performed at surgery centers by total charges as well as procedure volume.  

Topping the list is Extracapsular cataract removal, CPT code 66984, followed by an injection of onabotulinumtoxinA, HCPCSs code J0585, with nearly 900,000 procedures. OnabotulinumtoxinA is an injectable neurotoxin, better known under brand names such as Botox and Botox Cosmetics. 

Both lists of top procedures, by volume and by total charges, are dominated by diagnostic procedures such as colonoscopies and esophagogastroduodenoscopies with biopsies. Cataracts surgeries also topped both lists, with more than 1.2 million procedures reported in 2018 (most recent data available). Spinal injections were also common, including joint denervations.
