E648 – Excision of extensive endocardial scar
OHIP Surgical Assists Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
The description for E648 is 'excision of extensive endocardial scar, to ventriculotomy or aneurysm repair - add'. This is an add-on fee payable to the surgeon and must be claimed in conjunction with a primary procedure such as R746 (Ventricular aneurysm), R747 (Aneurysm of sinus of Valsalva), or a ventriculotomy procedure (e.g., R712, R710).
When to Use
- Use E648 when performing an endocardial scar excision during a ventricular aneurysm repair (R746).
- Use E648 when the excision of extensive endocardial scar is required as an adjunct to a ventriculotomy procedure such as R710 or R712.
Common Pitfalls
- Billing E648 as a standalone procedure; it will be rejected as it is strictly an add-on code requiring a primary surgical procedure.
- Failing to link E648 to the primary procedure code on the same claim, which causes automated rejection by the Ministry.
Billing Tips
- Ensure the primary procedure (e.g., R746 or R712) is listed first on the claim to establish the surgical context for the add-on fee.
- If the surgery occurs after hours, ensure the appropriate premium (E409 or E410) is applied to the primary procedure, as the add-on fee will follow the primary procedure's eligibility.
