E817 – Cystoscopy with catheterization of the ureter and retrograde injection of opaque media, unilateral
OHIP Surgical Assists Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
This service is an add-on to a primary cystoscopy procedure and is performed unilaterally. It involves passing a catheter into the ureter and injecting contrast media in a retrograde fashion to visualize the ureter and renal pelvis for diagnostic purposes. It is billed with suffix 'A' by the surgeon.
When to Use
- Use E817 when performing a retrograde pyelogram to investigate hematuria or suspected upper tract pathology during a diagnostic cystoscopy (Z606 or Z607).
- Use this code when you need to confirm ureteral anatomy or patency via contrast injection prior to other urological interventions.
Common Pitfalls
- Billing E817 alongside Z632, Z633, or Z634 will result in a rejection, as the primary cystoscopy is not payable when these tumor excision codes are claimed.
- Attempting to bill E817 bilaterally is incorrect; it is strictly a unilateral code, and you must use E818 if a retrograde pyelogram is performed on the contralateral side.
Billing Tips
- Ensure the primary cystoscopy code (e.g., Z606) is billed on the same claim, as E817 is an add-on procedure and will be denied if submitted independently.
- Always verify the patient's age to apply the correct age-based fee premium, as these percentages significantly increase the base value of this procedure.
