G144 – Brain stem evoked audiometry - professional component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
G144 is the professional component for brain stem evoked audiometry, which is an advanced diagnostic hearing test. The professional component involves the physician's interpretation of the test findings and the preparation of a report. The technical component of this service is billed separately under G146. As a professional component, this service must be rendered personally by the physician and cannot be delegated, as outlined in .
When to Use
- Use G144 when you are providing the formal physician interpretation and written report for an Auditory Brainstem Response (ABR) test.
- Bill G144 specifically for the professional component when the technical procedure itself is billed separately under G146.
Common Pitfalls
- Billing G144 without a corresponding, signed, and dated interpretation report in the patient chart will lead to recovery upon audit.
- Attempting to bill G144 for the technical performance of the test, which must be billed under G146, will result in a rejection for incorrect component billing.
- Submitting G144 without a valid referral from a physician or nurse practitioner as required by GP111 will trigger a rejection.
Billing Tips
- Ensure your documentation clearly distinguishes the professional interpretation (G144) from the technical execution (G146) to satisfy OHIP audit requirements for split-component billing.
