E722 – Cholecystectomy with transduodenal sphincterotomy
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Payable in addition to S287 (Cholecystectomy), this service is for the performance of a transduodenal sphincterotomy during the same operative session. This add-on increases the anaesthesia calculation by 1 basic unit.
When to Use
- Use E722 specifically when a transduodenal sphincterotomy is performed as an adjunct to a cholecystectomy (S287) to address common bile duct pathology.
- This code is the correct choice when the surgical approach requires opening the duodenum to access and divide the sphincter of Oddi during the cholecystectomy procedure.
Common Pitfalls
- Do not bill E722 if the sphincterotomy was performed endoscopically (ERCP); this code is strictly for the open transduodenal surgical procedure.
- Avoid billing E722 as a standalone procedure; it is an add-on code and will be rejected if not submitted on the same claim as S287.
Billing Tips
- Ensure the operative report explicitly details the transduodenal approach and the division of the sphincter to support the use of this specific add-on code.
- Remember that E722 adds 1 basic unit to the anaesthesia calculation, so ensure your anaesthesiologist is aware of this to maintain consistency in the total claim.
