CPT® Code 45905

The CPT® Code 45905 refers to the procedure of dilation of the anal sphincter, which is performed under anesthesia other than local anesthesia. This procedure is typically indicated for patients experiencing issues related to the anal sphincter, such as tightness or constriction that may lead to discomfort or difficulty with bowel movements. The process begins with the induction of anesthesia, ensuring that the patient is comfortable and pain-free during the procedure. Following this, the physician manually dilates the anal sphincter using their gloved hands. The procedure involves lubricating the anus to facilitate the insertion of fingers. The physician uses two fingers from one hand to lift and create space, while the index finger of the other hand is inserted to locate the constricting band within the sphincter. By applying gentle pressure along this band, the physician aims to release the constriction and achieve dilation. As the band releases, additional fingers may be inserted to reach the desired level of dilation. This procedure is classified as a separate procedure, indicating that it is distinct from other related interventions, such as those involving rectal strictures, which may require different techniques or tools for dilation.
