E770 – Endoscopic duodenoscopy and drainage of bile after I.V. CCK stimulation
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service is an add-on fee payable in addition to an oesophago-gastroduodenoscopy (`Z399, Z400`). This service is for the performance of duodenoscopy and the subsequent drainage of bile following intravenous (I.V.) cholecystokinin (CCK) stimulation. It must be claimed in conjunction with the primary endoscopy procedure code.
When to Use
- Use E770 specifically when performing a diagnostic duodenoscopy to collect bile for analysis immediately following the administration of intravenous CCK.
- This code must be appended to a primary endoscopy procedure such as Z399 or Z400 to signify the additional complexity of the CCK-stimulated bile collection.
Common Pitfalls
- Claiming E770 as a standalone procedure will result in rejection; it is strictly an add-on code that requires a primary endoscopy code on the same claim.
- Failure to document the administration of CCK and the subsequent successful collection of bile in the procedure note creates a significant audit risk for this specific add-on fee.
Billing Tips
- Ensure E770 is submitted on the same claim as your primary endoscopy code (e.g., Z399) to ensure the system recognizes the procedural link and processes the add-on fee correctly.
