2025 CPT code 50951

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

For chemotherapeutic agent provision, report both the specific service code and the code(s) for the substance(s)/drug(s). Modifier 50 is used for bilateral procedures. Some payers may require RT and LT modifiers.

Modifiers such as 22 (Increased Procedural Services), 50 (Bilateral Procedure), 52 (Reduced Services), 59 (Distinct Procedural Service), 73, 74, RT (Right Side) and LT (Left Side) may be applicable depending on the specific circumstances.

Medical necessity must be established by documenting the clinical indication for the procedure.

The physician prepares and anesthetizes the patient, then inserts the endoscope, guidewire, and performs the examination.They may also inject contrast for imaging. After the procedure, the physician removes the instruments and may reinsert the ureterostomy tube.

In simple words: The doctor uses a small camera on a thin tube to look inside your kidney, its drainage area, and the tube that carries urine from your kidney to your bladder. This is done through an opening that was already made in your skin during a prior surgery. They might also rinse the area, put in some fluids, or take x-rays.

This procedure involves inserting an endoscope through a pre-existing ureterostomy (a surgically created opening in the skin to the ureter) to examine the kidney, renal pelvis, and ureters.It may also include irrigation, instillation of solutions, and ureteropyelography (imaging of the ureter and renal pelvis). Radiologic services are reported separately.

Example 1: A patient with a history of ureteral stones has a ureterostomy and requires a follow-up examination to assess for recurrence., A patient with a ureteral stricture has a ureterostomy and undergoes endoscopic dilation., A patient with a ureteral tumor has a ureterostomy and undergoes endoscopic biopsy.

Documentation should include the reason for the endoscopy, findings, any procedures performed (e.g., biopsy, stone removal), and any complications.

** Radiological services (excluding ureteropyelography) should be reported separately if performed.
