CPT® Code 45020

The CPT® Code 45020 refers to the procedure of incision and drainage of a deep supralevator, pelvirectal, or retrorectal abscess. This surgical intervention is necessary when there is a collection of pus located in the deeper regions of the pelvic area, specifically above the levator ani muscle, around the rectum, or behind the rectum. The procedure aims to relieve pressure, remove infected material, and promote healing. During the process, a proctoscope or sigmoidoscope may be utilized to accurately locate the abscess. The technique involves making incisions, typically radial or cruciate, to ensure adequate drainage of the abscess. The specific approach taken depends on the abscess's location and origin, with careful dissection and probing to ensure complete drainage and to check for any associated complications, such as fistulous tracts. This procedure is critical for managing infections that can lead to significant morbidity if left untreated.
