E745 – Insertion of tubes and post-operative continuous peritoneal lavage
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
The E745 is an add-on fee for the insertion of tubes and post-operative continuous peritoneal lavage. This service must be billed in combination with another primary abdominal surgical procedure.
When to Use
- Use E745 when performing continuous peritoneal lavage following a major abdominal procedure such as a bowel resection or repair of a perforated viscus.
- Apply this code when the clinical necessity requires the placement of specialized drainage tubes specifically for the purpose of post-operative irrigation or lavage of the peritoneal cavity.
- Use this in conjunction with primary abdominal surgical codes (e.g., S312 or S321) where the lavage is an integral part of the post-operative management plan established during the initial surgery.
Common Pitfalls
- Billing E745 as a standalone service will result in an automatic rejection, as it is strictly an add-on code requiring a primary abdominal surgical procedure on the same claim.
- Confusing E745 with standard surgical drainage or simple wound irrigation; ensure the documentation explicitly supports 'continuous peritoneal lavage' to justify the add-on fee.
- Failing to link the procedure to the primary surgery on the claim, which may trigger audit flags if the primary procedure does not typically necessitate post-operative lavage.
Billing Tips
- Ensure the primary abdominal surgical procedure is listed first on the claim, followed by E745, to satisfy the dependency requirement for add-on services.
- If the procedure is performed after hours, apply the appropriate after-hours premium (E409 or E410) to the primary procedure, as E745 will inherit the eligibility for these premiums when billed together.
