Wiki Radiofrequency ablation confusion

[LANGLEY]

My physician dictated procedure note as Radiofrequency ablation of the bilateral L4-5 and L5-S1 facet joints via ablation of the L3-5 and sacral ala medial nerve branches. Should this be coded as
64635 50
64636 50

I agree that would represent 64635-50 for L4-5, 64636-50 for L5-S1
