S033
S033 – Closure of fistula - palate
OHIP Urology Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use S033 for the definitive surgical closure of a palatal fistula, typically following a previous cleft palate repair.
- Select S033 when the procedure involves local tissue advancement or flap closure specifically targeting a palatal defect, distinguishing it from general soft tissue repairs.
- Use S033 for fistula repairs that are distinct from primary cleft palate reconstruction, which would be billed under different codes such as S030.
Common Pitfalls
- Billing S033 alongside primary cleft palate repair codes (e.g., S030) without clear documentation of separate, distinct surgical sites may lead to rejection for unbundling.
- Failure to document the Injury Severity Score (ISS) when attempting to claim the E420 trauma premium for a fistula repair resulting from acute injury will result in audit recovery.
- Incorrectly applying after-hours premiums (E409/E410) to elective fistula closures that do not meet the criteria of being non-elective or delayed by an emergency.
Billing Tips
- Ensure the age of the patient is explicitly recorded to trigger the automatic age-based fee premium for patients under 16, which applies to both the surgeon and assistant fees.
- When billing for anaesthesia, ensure that any additional units for ASA physical status or patient positioning are calculated and added to the base 8 units to maximize the claim value.
