G167 – Hydrogen breath test - technical component
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This code represents the technical component of a hydrogen breath test, which covers the provision of premises, equipment, supplies, and personnel for performing the test. The corresponding professional component for interpretation is billed separately as G166. As per , the technical component of a diagnostic procedure is only eligible for payment where the physician has the necessary training and experience and maintains quality assurance documentation. Payment for this service is adjusted to 86.10% of the fee when rendered in a hospital.
When to Use
- Use G167 when you provide the equipment, supplies, and clinical space to perform a hydrogen breath test in your office setting.
- Use this code in conjunction with G166 when you are responsible for both the technical acquisition of the breath samples and the subsequent professional interpretation.
Common Pitfalls
- Billing G167 without maintaining the required quality assurance documentation for equipment calibration and staff training, which is a common trigger for audit recovery.
- Failing to apply the 86.10% fee reduction when the technical component is performed within a hospital facility rather than a private clinic.
Billing Tips
- Ensure your claim for G167 is always accompanied by a valid referral from a physician or nurse practitioner to satisfy the requirements outlined in GP111.
