Lumbar RFA after fusion

Patient has L3-L5 posterior fusion and R SI fusion. Complains of persistent low back/buttock pain worse to the right side. No extremity pain, just some intermittent n/t to lateral feet. Back pain worse with standing, no pain while seated. On exam, +facet loading in low back but nothing above fusion site. Tenderness over right SI. Would you do an L5 DR block by itself? Would insurance pay for this??
