CPT® Code 45005

The CPT® Code 45005 refers to the procedure of incision and drainage of a submucosal abscess located in the rectum. A submucosal abscess is a collection of pus that forms beneath the mucosal layer of the rectal wall, often resulting from infection or inflammation. This procedure is essential for alleviating pain, preventing further complications, and promoting healing by allowing the pus to escape. During the procedure, a proctoscope or sigmoidoscope may be utilized to accurately locate the abscess. The surgeon makes an incision, typically in a radial or cross-shaped (cruciate) manner, over the area where the abscess is most prominent, ideally as close to the anal verge as possible. This incision allows for the excision of the edges to expose the abscess cavity fully, facilitating effective drainage. Depending on the clinical situation, the incision may be left open to allow for continuous drainage, packed with iodophor gauze for a specified duration, or a drain may be placed to ensure proper outflow of any remaining fluid. This procedure is critical in managing rectal abscesses and preventing the development of more severe conditions, such as sepsis or the formation of fistulas.
