E705 – Colonoscopy into terminal ileum
OHIP Surgical Assists Code — DIGESTIVE SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E705 when you successfully intubate the terminal ileum during a diagnostic or screening colonoscopy (Z491-Z499) to evaluate for Crohn's disease or other ileal pathology.
- Apply this code when performing a surveillance colonoscopy (Z555) for inflammatory bowel disease where visualization of the terminal ileum is required for mucosal assessment.
Common Pitfalls
- Billing E705 without a valid primary colonoscopy code (Z491-Z499 or Z555) will result in an automatic rejection.
- Claiming E705 when the scope only reaches the cecum or ileocecal valve without documented entry into the terminal ileum is considered an audit risk for upcoding.
- Attempting to bill E705 alongside E740 or E741 is redundant, as those codes already include the procedural work of the colonoscopy.
Billing Tips
- Ensure your procedure note explicitly states 'terminal ileum intubated' to support the claim in the event of a post-payment audit.
- Always submit E705 on the same claim as the primary colonoscopy code to ensure the system recognizes the add-on relationship.
