I am in disagreement with my pain management provider regarding a planned L3/L4/L5 Medial Branch RFA. L4 continued to produce dermatomal radiation & was aborted. It was decided to proceed with L3/L5 RFA. My provider insists this would constitute ONE level. I disagreed, stating the Facet Joints at L3/L4 & L4/L5 were only partially denervated. My thought was it should be billed as 64635-52, and 64636-52 (reduced services because each joint at each level was only partially denervated). Any input would be so appreciated. Thank you!!
