G232 – Percutaneous spheno-palatine ganglion block with fluoroscopic guidance
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
Percutaneous spheno-palatine ganglion block with fluoroscopic guidance is an interventional pain injection procedure. It involves the injection of a substance near the spheno-palatine ganglion to manage conditions like certain types of headache and facial pain. Fluoroscopic guidance is a required component of this service.
When to Use
- Use G232 for patients with intractable cluster headaches or trigeminal autonomic cephalalgias requiring targeted spheno-palatine ganglion blockade under fluoroscopy.
- Select G232 when performing therapeutic nerve blocks for chronic facial pain syndromes where fluoroscopic visualization is essential for needle placement accuracy.
Common Pitfalls
- Billing G232 and G921 on the same day will trigger an automatic rejection as they are mutually exclusive procedures.
- Failing to document the use of fluoroscopic guidance in the procedure note will lead to recovery of funds during an audit, as it is a mandatory requirement for this code.
- Attempting to bill a separate anaesthetic fee when you are the physician performing the G232 procedure is prohibited under GP100.
Billing Tips
- Always append the E445 premium code to your claim if you utilize alcohol or other sclerosing solutions, which increases the G232 fee by 50%.
- If a separate physician provides sedation for the procedure, ensure they bill E030C or E031C to avoid claim conflicts with your primary procedure code.
