G910 – Cervical facet injection, first site
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
G910 is a percutaneous diagnostic injection for the cervical region, targeting the first site. This procedure, performed under fluoroscopic guidance, can be a facet medial branch block, facet joint injection, or sacral lateral branch block, as described in the Vertebral facet injections section on page . Each additional site treated during the same session should be claimed using G913.
When to Use
- Use G910 as the primary code for the first cervical facet joint injection or medial branch block performed under fluoroscopic guidance.
- Use G910 when performing a diagnostic block on a single cervical level, even if multiple needle placements are required for that specific site.
Common Pitfalls
- Billing G910 for multiple levels as separate G910 claims will result in rejection; only the first site is G910, while subsequent levels must be billed as G913.
- Attempting to bill G910 without fluoroscopic guidance documentation will lead to audit recovery, as the code specifically requires fluoroscopic verification.
Billing Tips
- Ensure the total number of G913 units claimed does not exceed seven, as the combined total for the session is capped at eight sites (one G910 plus seven G913).
