G815 – Electrocochleography - technical component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This code represents the technical component fee for performing Electrocochleography, billed per ear. As the technical component, it covers the provision of the premises, equipment, supplies, and personnel required to perform the procedure as outlined in the common elements of insured services (, ). The professional component, which covers the interpretation and report, is billed separately under G816. The physician claiming G815 must have the necessary training and experience to personally render the technical service and must maintain documentation on quality assurance processes ().
When to Use
- Use G815 when you provide the equipment, premises, and personnel for an electrocochleography procedure in an office or non-hospital setting.
- Bill G815 per ear when the technical data acquisition is performed, distinct from the professional interpretation billed under G816.
Common Pitfalls
- Billing G815 for a patient who is an inpatient or is admitted to the hospital within 24 hours for the same condition will result in a mandatory rejection.
- Failing to maintain documented quality assurance records for the equipment and data acquisition process is a primary audit risk that can lead to full recovery of paid claims.
- Attempting to bill G815 for services rendered within a hospital setting without applying the 86.10% payment adjustment rule for 'T' fee codes.
Billing Tips
- Always pair G815 with G816 on the same claim submission if you are performing both the technical and professional components to ensure the complete diagnostic service is captured.
