S324 – S324
OHIP Urology Code · Schedule of Benefits
Temporary abdominal closure with or without peritoneal washout
When to Use
- Use S324 for damage control laparotomy scenarios where the abdomen is left open with a temporary device like a Bogota bag or mesh to prevent abdominal compartment syndrome.
- Use S324 when performing a planned re-look laparotomy for fecal peritonitis where the fascial closure is intentionally deferred to a subsequent operative date.
Common Pitfalls
- Billing S324 alongside definitive fascial closure codes will result in an automatic rejection, as the code is strictly for temporary, non-definitive management.
- Attempting to bill S324 for the application of standard negative pressure wound therapy (NPWT) on a superficial incision is an audit risk, as it is explicitly excluded for superficial wound management.
- Submitting S324 when the patient is closed at the end of the same operative session is a common error that triggers recovery of funds during post-payment audits.
Billing Tips
- Ensure the operative report explicitly states that the fascia was left open and the procedure was a temporary measure, as this documentation is required to defend the claim against 'definitive closure' denials.
- If performing a major resection alongside the temporary closure, ensure the primary procedure is billed as the main item, as S324 is intended to be the standalone descriptor for the temporary closure phase.
