G649Professional component - 14 or more days recording

OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits

Professional component for a Level 1 continuous ECG monitoring (e.g. Holter) service with a recording duration of 14 or more days. Level 1 Requirements: The service must use a device capable of recording three or more simultaneous channels and acquire a continuous electrocardiographic recording of all beats using three or more skin electrodes. The device must also have the ability to analyze and manually review all parts of the recording, and to produce graphical and quantitative reports of relevant parameters and diagnostic quality tracings for visual review, including post-hoc review of any portion of the recording to enable diagnostic rhythm analysis. A patient diary and event marker capability must be included to enable symptom-rhythm correlation. The minimum monitoring duration for any Holter service is 12 hours. This professional component includes all the common elements of an insured service as described on pages - of the Schedule.

When to Use

  • Use G649 when the patient requires extended cardiac rhythm monitoring for 14 or more days to capture infrequent arrhythmias that would be missed by shorter duration monitors like G647 or G648.
  • Select G649 for patients with cryptogenic stroke or suspected paroxysmal atrial fibrillation where a standard 24-48 hour Holter is insufficient for diagnostic yield.

Common Pitfalls

  • Billing G649 in conjunction with G650, G653, or G656 will result in an automatic rejection as they are mutually exclusive professional components for the same recording.
  • Submitting G649 without ensuring the device meets the Level 1 requirement of three or more simultaneous channels and manual review capability will lead to audit recovery.

Billing Tips

  • Ensure the technical component and the professional component are billed separately if the physician is only providing the interpretation, as G649 strictly covers the professional component.
