G879
G879 – Ultrasound-guided injection (single) for G870, G873, G874 or G875
OHIP Diagnostic & Therapeutic Procedures Code — DIAGNOSTIC AND THERAPEUTIC PROCEDURES · Schedule of Benefits
When to Use
- Use G879 when performing an ultrasound-guided Botulinum toxin injection for cervical dystonia (G870) or focal spasticity (G873, G874, G875) to ensure precise needle placement in deep or small muscle groups.
- Apply this code when the clinical complexity of the patient's anatomy necessitates real-time visualization to avoid neurovascular structures during the injection procedure.
Common Pitfalls
- Billing G879 as a standalone service will trigger an automatic rejection; it must be submitted on the same claim as the corresponding parent injection code (G870, G873, G874, or G875).
- Attempting to bill separate diagnostic ultrasound codes (e.g., G384) alongside G879 is prohibited, as the guidance fee is intended to cover the imaging required for the injection site determination.
Billing Tips
- Ensure the injection site is clearly linked to the ultrasound guidance in your records, as G879 is strictly an add-on fee for the guidance component of the primary Botulinum toxin procedure.
