G689 – Technical component - 60 hours to 13 days scanning
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service represents the technical component of scanning a continuous electrocardiographic (ECG) recording from a Level 2 device. Level 2 monitoring is defined on page as using devices with fewer than three skin electrodes, or devices that record only portions of the monitoring period or do not provide trend analysis. The duration of the recording for this specific code is between 60 hours and 13 days. This code covers the scanning and analysis part of the technical service, separate from the recording component (G688) and professional interpretation component (G657).
When to Use
- Use G689 when you have performed the technical scanning and analysis of a Level 2 continuous ECG recording lasting between 60 hours and 13 days.
- Select this code specifically for the technical scanning component when the device used meets the Level 2 criteria of fewer than three electrodes or lacks automated trend analysis.
Common Pitfalls
- Billing G689 in conjunction with G657 for the same patient on the same day is permitted, but ensure you are not also billing for a Level 3 monitoring code (e.g., G650-G656) which would be an incorrect classification for Level 2 devices.
- Submitting G689 for recordings shorter than 60 hours will result in rejection; use G688 or appropriate shorter-duration codes instead.
- Failing to maintain the required quality assurance documentation as specified in GP11 creates a significant audit risk for the technical component fee.
Billing Tips
- If the service is performed within a hospital setting, remember that the payment is automatically adjusted to 86.10% of the listed fee as per the GP11 rules.
