G682 – Continuous ECG monitoring - technical component - 36 to 59 hours recording
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service represents the technical recording component for a Level 1 continuous ambulatory electrocardiographic (Holter) monitoring session lasting from 36 to 59 hours. Level 1 Requirements: - A device capable of recording three or more simultaneous channels. - Acquisition of a continuous ambulatory electrocardiographic recording of all beats, using three or more skin electrodes. - The device must have the ability to analyze and manually review all parts of the recording. - The device must be able 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. - Must include a patient diary and event marker capability to enable symptom-rhythm correlation. - A minimum of 12 hours of monitoring is required for any Holter service.
When to Use
- Use G682 when the Holter monitor recording duration exceeds 36 hours but remains under 60 hours, as G681 is restricted to 12-35 hours.
- Select G682 for patients requiring extended rhythm monitoring beyond the standard 24-hour window to capture intermittent arrhythmias that are not detected in shorter sessions.
Common Pitfalls
- Billing G682 without the mandatory accompanying G683 (technical scanning) and G658 (professional component) will result in an incomplete claim submission.
- Submitting G682 for a recording that is less than 36 hours is a common audit trigger; ensure the device timestamp confirms the duration exceeds the 36-hour threshold.
- Attempting to bill G682 in conjunction with G651 or G652 is prohibited, as those codes represent different monitoring durations and technical requirements.
Billing Tips
- Ensure the technical component claim (G682) is submitted alongside the scanning (G683) and professional (G658) components in the same batch to maintain billing integrity and avoid payment delays.
- If the service is performed in a hospital setting, ensure you use the G682A suffix to correctly apply the 94.68% payment adjustment rule.
