G653 – Professional component - 12 to 35 hours recording
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This is the professional component for a Level 2 continuous ECG monitoring service, covering a recording period of 12 to 35 hours. Level 2 Criteria: This service applies to monitoring devices with: - Fewer than three skin electrodes, or - Devices that record only portions of the monitoring period, or - Devices that do not provide trend analysis. A minimum of 12 hours of monitoring is required. The service should include a patient diary and event marker capability to enable symptom-rhythm correlation. The professional component involves the physician's interpretation, analysis, and reporting on the recorded data.
When to Use
- Use G653 for standard 24-hour Holter monitoring when the device used is a limited-lead system (e.g., single-lead patch monitor) that does not meet the criteria for Level 1 full-disclosure analysis.
- Select G653 when the monitoring duration is between 12 and 35 hours and the device lacks automated trend analysis features required for higher-level billing codes.
Common Pitfalls
- Billing G653 in combination with G650 or G658 for the same recording session will trigger an automatic rejection due to mutually exclusive professional component restrictions.
- Submitting G653 for recordings under 12 hours is a common audit trigger; ensure the technical report explicitly confirms the total duration of the recording period.
Billing Tips
- Ensure the technical component is billed separately using the appropriate technical fee code, as G653 strictly covers the physician's professional interpretation and reporting.
