S521 – Litholapaxy and removal of fragments
OHIP Urology Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
The full description should reference page as the listing page for S521, not .
When to Use
- Use S521 for the endoscopic fragmentation and removal of bladder calculi when performed via cystoscopy.
- Use this code for litholapaxy procedures where mechanical or ultrasonic energy is applied to break down stones for extraction.
Common Pitfalls
- Do not bill S521 in addition to other cystoscopic procedures that include stone removal as part of the primary procedure, as this may be flagged as unbundling.
- Failure to document the specific method of fragmentation (e.g., mechanical, laser, or ultrasonic) can lead to claim rejections during manual audits.
Billing Tips
- If the procedure is performed laparoscopically, ensure you append the E792 premium to receive the 25% fee increase.
- Always verify the patient's age at the time of service to automatically apply the appropriate age-based premium from the GP64 schedule.
