G687 – Technical component - 36 to 59 hours scanning
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This is the technical scanning component for a Level 2 continuous ECG (Holter) monitoring service. The monitoring period for this code is from 36 to 59 hours. A Level 2 device is defined as having fewer than three skin electrodes, or a device that records only portions of the monitoring period, or does not provide trend analysis. The total monitoring period must be a minimum of 12 hours. This fee covers the scanning of the acquired data. See related codes for technical recording (G686) and the professional interpretation component (G656).
When to Use
- Use G687 when the Holter monitor device used meets the Level 2 criteria of fewer than three electrodes or lacks trend analysis, and the recording duration falls strictly between 36 and 59 hours.
- Use this code specifically for the technical scanning component when the data acquisition phase is billed separately under G686.
Common Pitfalls
- Billing G687 when the total recording duration is less than 36 hours, which would instead require the use of G685.
- Submitting G687 for a device that provides full trend analysis or uses three or more electrodes, as these require Level 1 codes (G684 or G685) instead.
- Claiming G687 alongside G688 or G689 for the same patient and recording period, as these are mutually exclusive based on the duration and device level.
Billing Tips
- Ensure the technical recording component (G686) and the professional interpretation (G656) are billed separately to capture the full service value, as G687 only covers the scanning portion.
