G217 – Percutaneous trigeminal ganglion block with fluoroscopic guidance
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
This service is for a percutaneous trigeminal ganglion block utilizing fluoroscopic guidance. This procedure is listed under 'Ganglion/Plexus injections' in the Diagnostic and Therapeutic Procedures section of the Schedule. An additional premium, E445, is payable if alcohol or other sclerosing solutions are used.
When to Use
- Use G217 when performing a diagnostic or therapeutic trigeminal ganglion block specifically requiring fluoroscopic guidance for needle placement.
- Select G217 for patients with trigeminal neuralgia when the procedure involves targeting the Gasserian ganglion rather than peripheral nerve branches covered under other G-series codes.
Common Pitfalls
- Billing G217 without documenting the use of fluoroscopy, which is a mandatory requirement for this specific code.
- Failing to append E445 when using alcohol or phenol for neurolysis, resulting in a 50% loss of the potential procedural fee.
- Confusing G217 with peripheral nerve blocks; ensure the anatomical target is the ganglion to avoid audit discrepancies regarding the complexity of the procedure.
Billing Tips
- Always confirm the use of sclerosing agents in the operative note to justify the addition of E445, as this is a frequent target for post-payment review.
