CPT® Code 45520

Perirectal injection of sclerosing solution for prolapse, as described by CPT® Code 45520, is a medical procedure aimed at addressing rectal prolapse, which can manifest in two forms: partial and complete. Partial rectal prolapse is characterized by the protrusion of only the rectal mucosa through the anus, while complete rectal prolapse involves the protrusion of a portion of the entire thickness of the rectum. The primary objective of this procedure is to treat partial prolapse effectively. During the procedure, a sclerosing solution, which may include agents such as saline, alcohol, or phenol, is prepared for injection. To ensure accurate placement of the needle tip, a gloved finger may be inserted into the rectum, providing tactile guidance. The sclerosing solution is then infiltrated into the perirectal tissue, specifically targeting the lateral and posterior areas, to promote tissue adhesion and reduce the prolapse. This method is a minimally invasive approach that aims to alleviate the symptoms associated with rectal prolapse and improve the patient's quality of life.
