E651 – Coronary endarterectomy and/or gas endarterectomy
OHIP Surgical Assists Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
When to Use
- Use E651 when performing a formal endarterectomy of a coronary artery to remove atherosclerotic plaque during a primary bypass procedure (R742 or R743).
- Use E651 when gas endarterectomy is specifically utilized to clear a coronary vessel as part of the primary revascularization strategy.
Common Pitfalls
- Claiming E651 as a standalone procedure; it is strictly an add-on and will be rejected if not linked to a primary coronary artery repair code like R742 or R743.
- Failing to document the specific technique (endarterectomy or gas endarterectomy) in the operative report, which risks recovery during a post-payment audit.
Billing Tips
- Ensure E651 is submitted on the same claim as the primary coronary artery repair to trigger the correct payment logic.
- If performing endarterectomy on multiple vessels, verify if the Schedule allows for multiple units of E651 or if it is a flat fee per operative session.
