E743 – Entero-enterostomy
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E743 when performing a Roux-en-Y limb construction to divert bile flow during a choledochoenterostomy (S281).
- Use E743 when a cholecystoenterostomy (S283) requires an additional entero-enterostomy to prevent reflux or manage biliary anatomy.
Common Pitfalls
- Billing E743 as a standalone procedure will result in an automatic rejection; it must be linked to a primary S281 or S283 claim.
- Attempting to bill E743 for a standard anastomosis that is already considered an integral component of the primary S281 or S283 procedure will lead to audit recovery.
Billing Tips
- Ensure the primary procedure (S281 or S283) and the add-on code E743 are submitted on the same claim to trigger the correct processing logic.
