CPT® Code 50957

Ureteral endoscopy through established ureterostomy, with or without irrigation, instillation, or ureteropyelography, exclusive of radiologic service; with fulguration and/or incision, with or without biopsy

Ureteral endoscopy is a minimally invasive procedure that involves the examination and treatment of the ureter, which is the duct that carries urine from the kidney to the bladder. This specific procedure, identified by CPT® Code 50957, is performed through an established ureterostomy, which is an opening created surgically to allow urine to exit the body directly from the ureter. The ureteroscope, a specialized instrument equipped with a camera and light, is introduced through this stoma or a ureteral catheter that exits the skin. During the procedure, the physician inspects the ureter for any abnormalities, such as abnormal tissue growths, foreign bodies, or calculi (stones). The procedure may also involve the irrigation of the ureter with normal saline to clear any obstructions or debris. Additionally, diagnostic or therapeutic solutions can be instilled into the ureter for further evaluation or treatment. If necessary, contrast material may be injected to perform ureteropyelography, a radiologic examination of the ureter and renal pelvis, although this specific service is not included in the CPT® code description. In cases where abnormal tissue is identified, the physician may perform fulguration, which involves the use of an electrocautery device to destroy the abnormal tissue. Alternatively, a laser or cryoprobe may be utilized for tissue destruction. The procedure may also include an incision of the abnormal tissue, which can be performed in conjunction with fulguration. If a biopsy is indicated, tissue samples can be obtained using biopsy forceps introduced through the ureteroscope. This comprehensive approach allows for both diagnostic and therapeutic interventions during a single procedure, enhancing patient care and outcomes.
