Billing and Coding: Facet Joint Interventions for Pain Management

This billing and coding policy covers cervical/thoracic and lumbar/sacral facet joint interventions (diagnostic and therapeutic injections, medial branch blocks, radiofrequency ablation, and chemical denervation) when performed with image guidance (fluoroscopy or CT) and billed with appropriate CPT codes.
