CPT® Code 53405

Urethroplasty is a surgical procedure aimed at reconstructing the urethra, which is the tube that carries urine from the bladder to the outside of the body. This specific procedure, identified by CPT® Code 53405, represents the second stage of a two-stage urethroplasty process. The first stage, coded as CPT® 53400, involves the harvesting of a skin graft, which can be taken from various donor sites, including the foreskin in uncircumcised males, or from the inner thigh, groin, buttocks, or buccal mucosa. The second stage, denoted by CPT® 53405, is performed after the graft has healed and the epithelial tissue has become vascularized, meaning it has developed a blood supply. During this stage, the vascularized tissue is carefully excised to create a tubular structure that will replace the damaged or obstructed section of the urethra. This procedure is critical for restoring normal urinary function and is typically indicated for patients with strictures, diverticula, or fistulas affecting the urethra. The meticulous nature of the surgery requires precise calibration of the urethral openings and careful suturing to ensure proper healing and function of the newly formed urethra.
