E658 – HIS Bundle ablation
OHIP Surgical Assists Code — CARDIOVASCULAR SURGICAL PROCEDURES · Schedule of Benefits
HIS Bundle ablation is an add-on surgical procedure. This code is intended to be claimed in addition to a primary cardiac procedure. It is listed in the context of cardiotomy procedures such as `R712, R713, and R714.
Note: This service may not be payable with `R711 (Division of accessory conduction pathway) as the description for R711 states it is inclusive of mapping with or without HIS bundle`.
When to Use
- Claim E658 as an add-on procedure when performing a HIS bundle ablation in conjunction with a primary cardiotomy procedure such as R712, R713, or R714.
- Use this code specifically for the ablation component when the primary surgical procedure does not already include mapping or ablation of the HIS bundle in its definition.
Common Pitfalls
- Do not bill E658 alongside R711, as the R711 fee schedule explicitly states that its description is inclusive of HIS bundle mapping and ablation.
- Avoid billing E658 as a standalone procedure; it is strictly an add-on code and requires a primary cardiac surgical procedure to be valid for payment.
Billing Tips
- Ensure the primary procedure code (e.g., R712, R713, or R714) is submitted on the same claim to avoid automatic rejection of the add-on code E658.
