R936 – Mesenteric or celiac artery repair - endarterectomy or graft
OHIP Radiology Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
A surgical procedure for the repair of a mesenteric or celiac artery, which involves either an endarterectomy or the placement of a graft. This is a cardiovascular surgical procedure listed under 'Mesenteric or celiac artery repair' on page of the Schedule. - Assistant Fee Calculation: Based on 10 basic units plus time units as per the rules on . - Anaesthesia Fee Calculation: Based on 10 basic units plus time units as per the rules on .
When to Use
- Use R936 for the surgical repair of a mesenteric or celiac artery via endarterectomy to address chronic mesenteric ischemia.
- Use R936 when performing a bypass graft procedure specifically on the mesenteric or celiac artery to restore blood flow.
- Use R936 for open surgical revascularization of the mesenteric circulation, ensuring it is distinguished from purely endovascular interventions.
Common Pitfalls
- Do not bill R936 if the procedure performed is an excision of the celiac ganglion; use R935 for that specific service.
- Avoid billing R936 for endovascular stenting or angioplasty, as this code is intended for open surgical repair (endarterectomy or graft).
- Do not assume automatic payment for a second surgical assistant; R936 is not on the pre-approved list and requires prior authorization from a medical consultant.
Billing Tips
- Ensure the operative report clearly distinguishes between an endarterectomy or graft placement to support the use of R936 over other vascular repair codes.
- When billing for trauma-related mesenteric repair, ensure the Injury Severity Score (ISS) is documented in the chart to support the E420 trauma premium.
