CPT® Code 46270

A surgical treatment for anal fistula, specifically coded as CPT® Code 46270, involves the procedures of fistulotomy or fistulectomy targeting subcutaneous anal fistulas. An anal fistula is defined as an abnormal connection between two epithelial surfaces, typically resulting from an infection or abscess in the anal region. The procedure begins with the identification of the fistula tract, which may involve the use of a probe or suture to trace the external opening to its internal counterpart. Once the tract is located, the surgeon can either incise and open the fistula (fistulotomy) to facilitate healing from the inside out or excise the entire tract (fistulectomy). This surgical intervention is crucial for alleviating symptoms associated with anal fistulas, such as pain and discharge, and promoting proper healing. It is important to note that different codes are used for various types of anal fistulas based on their complexity and location, with CPT® Code 46270 specifically designated for subcutaneous anal fistulas. The procedure may also involve the placement of an anal seton, which is a length of non-absorbable suture material used to manage the fistula tract, either for drainage or to gradually open the tract over time. This comprehensive approach aims to minimize complications, such as incontinence, particularly when the fistula traverses the anal sphincter.
