G694 – Technical component – 14 or more days recording
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service is the technical recording component for a Level 2 continuous ambulatory electrocardiographic (ECG) monitoring for a period of 14 or more days. Level 2 Monitoring Definition: A Level 2 device is defined as any monitoring device with fewer than three skin electrodes, or one that records only portions of the monitoring period, or does not provide trend analysis. The monitoring period must be a minimum of 12 hours (:). As a technical component, this service includes providing the premises, equipment, supplies, and personnel for the service elements (:). The physician claiming this technical component is responsible for the complete quality assurance process for all elements of the service, including data acquisition, reporting, and record keeping (:).
When to Use
- Use G694 for the technical component of a 14-day continuous ambulatory ECG study when using a Level 2 device that utilizes fewer than three electrodes.
- Select G694 when the monitoring device does not provide automated trend analysis, distinguishing it from the higher-tier G696 Level 1 monitoring.
Common Pitfalls
- Billing G694 in conjunction with G695 or G696 for the same recording period will trigger an automatic rejection as only one technical component is permitted per patient per recording.
- Submitting G694 for a study duration of less than 14 days is a common audit trigger; ensure the device logs confirm the full 14-day technical capture.
Billing Tips
- If the technical component is performed within a hospital setting, ensure your billing software applies the 94.68% fee adjustment to comply with the hospital-based service rule.
