Does anyone know how to bill for an SI Joint RFA? OP report states physician ablated S1 and 2 lesions in SI joint for a total of 3 burns. I am confused as to how to bill this. Coding rules state per nerve and, technically she only burned 1 nerve(S1) but the tricky part is these 2 lesions. Pt is Medicare, which only makes this more difficult.

I'm thinking:
64622
64623 x 2

Please Help!!:confused:
 
RFA is per level, not lesion and anatomically, there is no facet joint after the
L5-S1 level, so 64623 would not be appropriate for the SI joint. I would code 64622 x1 for the S1 level and 64640 x1 for the SI level.
