S452 – Ureteroileal conduit
OHIP Urology Code — UROGENITAL AND URINARY SURGICAL PROCEDURES · Schedule of Benefits
S452 is a fee code for a surgical procedure. As a surgical code, it is eligible for billing with suffix 'A' for the performing surgeon, 'B' for a surgical assistant, and 'C' for an anaesthesiologist (). The surgeon's fee is a set amount, while the fees for anaesthesia and surgical assistance are calculated based on basic units specific to the procedure plus time units based on the duration of the service, as outlined in the General Preamble (-, -). The specific details, specialty, and base unit values for S452 are not provided in the context.
When to Use
- Use S452 for the creation of a urinary diversion via an ileal conduit following cystectomy or other bladder-disabling conditions.
- Use S452 when performing the primary construction of the ureteroileal anastomosis and the subsequent cutaneous stoma.
Common Pitfalls
- Billing S452 on the same day as S482 is a common rejection; ensure you are not attempting to bill both for the same operative session.
- Failure to document the specific surgical approach or complexity can lead to audit scrutiny regarding the medical necessity of the procedure.
Billing Tips
- Ensure the surgeon uses suffix 'A', the assistant uses 'B', and the anaesthesiologist uses 'C' to avoid automatic rejection of the claim.
- When billing for the anaesthesiologist, remember that basic units for the procedure are fixed; ensure all applicable add-on units (e.g., E022C, E010C) are included to maximize the time-unit calculation.
