CPT® Code 49020

An abscess is defined as a localized collection of pus that can occur in various parts of the body. Specifically, a peritoneal abscess refers to an accumulation of pus within the peritoneum, which is the membrane lining the abdominal cavity. This type of abscess may also be referred to as an intraperitoneal abscess. The presence of localized peritonitis indicates inflammation of the peritoneal tissue in a specific area, often associated with infection or the presence of an abscess. The procedure described by CPT® Code 49020 involves making an incision in the abdomen to access the peritoneal cavity. During this surgical intervention, the entire cavity is explored to locate the abscess. The surgeon separates any loculations, which are compartments within the abscess, and thoroughly evacuates all debris, including pus, blood, and necrotic tissue. To ensure complete removal of infectious material, the abscess site is irrigated vigorously with sterile saline or an antibiotic solution. Following the irrigation, a drain is placed within the abscess cavity to facilitate ongoing drainage, and the abdomen is subsequently closed around the drain to promote healing and prevent further complications.
