G912
G912 – Lumbar/Sacral facet injection, first site
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use G912 as the primary code for the first lumbar or sacral facet joint injection or medial branch block performed under fluoroscopic guidance.
- Use G912 when performing a diagnostic block on a single level, even if multiple nerves (e.g., medial branches at one level) are targeted at that specific site.
Common Pitfalls
- Billing G912 more than 6 times in a 12-month period without prior Ministry of Health authorization will result in automatic rejection.
- Failing to document the use of fluoroscopic guidance is a common audit trigger, as this is a mandatory requirement for G912 eligibility.
- Attempting to bill G912 for multiple levels as separate G912 claims instead of using G913 for the additional sites will lead to payment errors or audit flags.
Billing Tips
- Always bill G912 as the base code and append G913 for each subsequent site treated during the same session, up to a maximum of 7 additional sites.
- Ensure the procedural note explicitly states the use of fluoroscopy to satisfy the specific documentation requirements for J-section interventional pain procedures.
