Which specialty accounts for about 30% of ASC procedures?

• A. Ophthalmology 30%
• B. Orthopedics 15%
• C. Pain and Neurology 10%
• D. Gastrointestinal 14%

Answer: (A)

Ophthalmology earns the largest share in many ambulatory surgery center mixes because cataract surgeries are extremely common, quick, and easy to discharge from the facility. These procedures are typically short, done under local anesthesia, require minimal postoperative monitoring, and have high success rates, making them highly suitable for an outpatient setting. That combination drives a substantial portion of ASC volume, often around 30%.

The other specialties contribute fewer procedures in this mix. Orthopedics includes many higher-acuity or longer cases that may extend stay or require more resources, so its share tends to be around 15%. Pain and neurology procedures, such as injections or related interventions, are less frequent in the ASC setting and account for about 10%. Gastrointestinal, while a significant portion of ambulatory care, usually occurs in endoscopy-focused centers and tends to be a bit lower than ophthalmology in this specific mix, around the mid-teens.

So, the reason ophthalmology is the best answer is that cataract surgery provides a high-volume, quick-turnover, outpatient-ready workflow, which pushes it to the roughly 30% mark in ASC procedure mix.
