Top inpatient and outpatient surgical procedures

Surgery is a medical treatment provided through an incision in the body large enough for the procedure to be performed. Whether it is elective or emergency, surgery is done for many reasons, such as making or confirming a diagnosis, repairing or transplanting tissues or organs, implanting a medical device, improving physical appearance, and much more.

According to our healthcare commercial intelligence, more than 1.5 billion surgeries were performed for calendar year 2022.

Inpatient vs. outpatient surgery

Inpatient and outpatient surgical procedures have important differences that impact patient care, healthcare costs, and resource allocation in the healthcare system.

The key difference is that inpatient surgeries are performed in a hospital setting, and patients typically stay there for at least one night after the procedure. These surgeries are generally reserved for patients with more complex or serious medical conditions and subsequently require extensive post-operative care and monitoring. Outpatient surgeries, also known as same-day or ambulatory surgeries, may be performed in a surgical center or hospital, but the patient is discharged the same day as the procedure.

Using intelligence from the Atlas All-Payor Claims Dataset, the following tables rank the most commonly performed inpatient and outpatient surgical procedures.

What are the most common inpatient surgical procedures?

The most common inpatient surgical procedure performed in 2022 was ICD-10 code 02HV33Z. This cardiac procedure involves the insertion of a central catheter that ultimately terminates the patient’s superior vena cava, a large, valveless vein that pumps deoxygenated blood from the upper half of the body and returns it to the right atrium. This procedure accounted for 5.7% of all inpatient surgeries done in 2022.

In second place is ICD-10 code 0BH17EZ. This procedure involves the insertion of an endotracheal tube that is placed between the vocal cords and through the trachea. The device provides oxygen to the lungs and protects the lungs from contamination. The procedure accounted for 2.7% of all inpatient surgical procedures in 2022.

In third place is ICD-10 code 0DJ08ZZ. This procedure examines a patient’s upper digestive system to diagnose or treat certain conditions. A specialist typically administers this procedure with the help of a tiny camera on the end of a long, flexible tube. This procedure accounted for 1.7% of all inpatient surgeries done in 2022.

What are the most common outpatient surgical procedures?

CPT Code 11042 comes in first place, accounting for 4.7% of all outpatient surgical procedures done in 2022. This procedure involves the removal of unhealthy or dead tissue surrounding a wound, to give the area the opportunity to heal and reduce the risk of infection.

CPT Code 36591 involves the healthcare provider collecting a blood specimen from a patient who has had a venous access device completely implanted within them in a prior procedure. The procedure accounted for 3.5% of all outpatient surgeries.

In third place is CPT Code 20610, which accounted for 3.4% of all outpatient surgeries performed in 2022. In this procedure, the healthcare provider uses a needle and syringe to inject a drug or remove fluid from within a patient’s joint.
