When to Use
- Use G146 to bill for the technical equipment and personnel costs when performing brain stem evoked audiometry in an office setting.
- Always pair G146 with G144, which covers the professional interpretation component, to ensure the full service is captured.
Common Pitfalls
- Billing G146 for a patient who is an inpatient or who is admitted to the hospital within 24 hours of the service will result in a mandatory rejection.
- Failing to apply the 86.10% fee reduction when the technical service is performed within a hospital facility will trigger an automatic payment adjustment or audit flag.
Billing Tips
