G141 – Cortical evoked audiometry - professional component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service represents the professional component for cortical evoked audiometry, which is the interpretation and report of the test. A professional component is a class of service listed in the Schedule headed by a column listed 'P' or with 'professional component' listed opposite the service (:). The corresponding technical component is billed under G143. For cortical evoked audiometry with multiple frequencies as required by WSIB, see Appendix F of the Schedule.
When to Use
- Use G141 to bill for the professional interpretation and reporting of cortical evoked audiometry results when the technical component is performed separately.
- Apply this code when acting as the interpreting physician for diagnostic testing that utilizes cortical evoked potentials to assess auditory pathway integrity.
Common Pitfalls
- Billing G141 without the corresponding technical component G143 can trigger audit flags if the facility or equipment ownership is not clearly delineated.
- Attempting to bill G141 for standard pure-tone audiometry (which is typically included in office visit assessments) rather than specialized cortical evoked diagnostic procedures.
Billing Tips
- Ensure the report generated for G141 is distinct and stored in the patient record to justify the professional component fee separate from the technical G143 charge.
