CPT® Code 49060

A retroperitoneal abscess is defined as a localized collection of pus situated in the abdominal cavity, specifically behind the peritoneum, which is the membrane lining the abdominal wall and covering the abdominal organs. This type of abscess may also be referred to as an extraperitoneal abscess due to its location outside the peritoneal cavity. The procedure coded as CPT® 49060 involves the surgical drainage of this abscess through an open approach. Surgeons can access the retroperitoneum via various incisions, including an anterior or posterior subcostal incision, a midline abdominal incision, or a flank incision, depending on the specific circumstances and location of the abscess. During the procedure, the entire retroperitoneal cavity is thoroughly explored to locate the abscess. Once identified, loculations within the abscess are separated, and all debris, which may consist of pus, blood, and necrotic tissue, is meticulously evacuated. To ensure complete removal of all infectious material, the abscess site is vigorously irrigated with sterile saline or an antibiotic solution. Following the irrigation, a drain is strategically placed within the abscess cavity to facilitate ongoing drainage, and the incision is then closed around the drain to promote healing while allowing for continued monitoring and management of the abscess site.
