L699 – L699
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L699 as a mandatory diagnostic code when billing for the interpretation of a 12-lead ECG (G365) in a clinical setting.
- Apply this code when the ECG is performed and interpreted by the physician to support the diagnostic evaluation of cardiac symptoms.
Common Pitfalls
- Billing L699 without an associated G365 will result in a rejection, as L699 is a diagnostic code linked to the technical and professional component of the ECG.
- Do not use L699 for rhythm strips or monitoring; it is strictly reserved for the formal 12-lead ECG interpretation.
Billing Tips
- Ensure the diagnostic code L699 is entered in the diagnostic field of your claim to satisfy the requirement for the G365 service code.
