Excellus's facet joint injection and medial branch block policy, effective October 15, 2026, sets criteria for diagnostic and therapeutic facet injections and applies them only to facet-mediated pain. The 06/18/26 annual review left the policy intent unchanged. Injections performed under ultrasound guidance, or with injectates other than anesthetic, corticosteroid or contrast agents, are considered investigational, and injections on more than three contiguous levels are considered not medically necessary.

01Already effective 2026-10-15: Claims for a diagnostic facet joint injection need documentation of pain persisting for at least 3 months despite at least 4 weeks of appropriate conservative treatment in the past 3 months, or the reason conservative treatment is contraindicated; predominantly axial pain from C2-C3 to L5-S1; no more than three facet levels per session; and a facet radiofrequency denervation or ablation being considered.
02A second diagnostic injection needs a positive response of at least 80% relief from the first at the same level.
03Therapeutic injections given as an alternative to radiofrequency ablation need a contraindication (established spinal pseudoarthrosis or an implanted electrical device) and two documented positive diagnostic injections at the same level.
04Injections performed without fluoroscopic or CT guidance, on the same day as another invasive procedure, above C2-C3 or below L5-S1, or after a prior successful radiofrequency ablation at the requested level are considered not medically necessary.
