E836
E836 – EMR of very large sessile polyp/lesion (>3cm) upper GI
OHIP Surgical Assists Code · Schedule of Benefits
When to Use
- Use E836 when performing a piecemeal resection of a sessile upper GI lesion exceeding 3cm that necessitates a submucosal injection to elevate the tissue.
- Select E836 instead of E674 or E703 when the lesion size exceeds 3cm and requires the specific piecemeal technique rather than a single-snare excision.
Common Pitfalls
- Billing E836 for lesions under 3cm or those removed in a single piece will result in automatic rejection or audit recovery as it fails the 'piecemeal' requirement.
- Attempting to bill separate hemostatic techniques (e.g., clips or cautery) alongside E836 is prohibited, as these are considered included in the procedure fee.
- Failure to link E836 to the correct base procedure code (Z399, Z515, or Z527) will cause the claim to be rejected for missing the required primary service.
Billing Tips
- Ensure your operative report explicitly documents the use of submucosal injection and the piecemeal nature of the resection to satisfy the specific requirements for this code.
- Since E836 is an add-on, always ensure the primary procedure code (Z527, Z515, or Z399) is billed on the same claim to trigger the payment for the EMR.
