S410 – Calycectomy with Diversion of Urine
OHIP Urology Code — Kidney and Upper Urinary Tract · Schedule of Benefits
Calycectomy with diversion of urine is a surgical procedure listed in the Urogenital and Urinary Surgical Procedures section of the Schedule of Benefits. It involves the excision of a renal calyx. As a surgical procedure, it includes all common and specific elements of surgical services. The service is eligible for surgeon (suffix A), assistant (suffix B), and anaesthetist (suffix C) fees. The assistant and anaesthetist fees are calculated based on 7 base units plus time units, as detailed on pages and of the Schedule.
When to Use
- Use S410 when performing a formal excision of a renal calyx specifically combined with a urinary diversion procedure.
- Use S410 for partial nephrectomy-type procedures where the primary intent and surgical action is the removal of a calyx and the establishment of a diversion, rather than a simple nephrectomy (S415) or pyeloplasty (S411).
Common Pitfalls
- Billing S410 alongside other major kidney procedures like S415 (Nephrectomy) without clear documentation of separate, distinct surgical sites or indications, which may trigger a rejection for unbundling.
- Assuming a second assistant is automatically payable; S410 is not on the pre-approved list, and claims for a second assistant will be rejected without prior written authorization from a medical consultant.
Billing Tips
- Ensure the operative report explicitly details the 'diversion' component of the procedure, as the code specifically requires both the calycectomy and the diversion to be eligible for the full fee.
