CPT® Code 50955

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

Ureteral endoscopy is a minimally invasive procedure that involves the examination and treatment of the ureter, which is the tube that carries urine from the kidney to the bladder. This specific procedure, identified by CPT® Code 50955, is performed through an established ureterostomy, which is an opening created surgically on the abdominal wall that allows urine to exit the body directly from the ureter. During the procedure, a ureteroscope, a specialized endoscopic instrument, is introduced through the ureterostomy to visualize the ureter's internal structure. The primary purpose of this endoscopy is to inspect the ureter for any abnormalities, such as abnormal tissue growths, foreign bodies, or calculi (stones). In addition to visual inspection, the procedure may involve irrigation of the ureter with normal saline to clear any obstructions or debris. Furthermore, diagnostic or therapeutic solutions may be instilled to aid in the evaluation or treatment of the ureter. If necessary, contrast material can be injected to perform ureteropyelography, a radiologic procedure that provides detailed imaging of the urinary tract, although this imaging service is not included in the CPT® Code 50955. A key component of this procedure is the biopsy, where biopsy forceps are introduced through the ureteroscope to obtain tissue samples for pathological examination. This allows for the diagnosis of potential malignancies or other pathological conditions affecting the ureter. Overall, CPT® Code 50955 encompasses a comprehensive approach to diagnosing and managing ureteral conditions through endoscopic techniques.
