So I have a patient who had lumbar medial branch blocks done with near 100% relief immediately post procedure. I put a small amount of steroid (10mg kenalog) in the block to give her some longer lasting relief until we got her RFA approved. Spoke to a doc at her insurance company and they approved RFA. Performed RFA. Now a new doc calling from insurance company stating the RFA is now NOT approved because I used steroid and that is a therapeutic block not a diagnostic block, regardless of the immediate relief she received post procedure. So, now I'm not going to get reimbursed for the RFAs I already performed. Anyone else have this issue? I have never had this problem before. He is requesting literature to "support my practice as it is not standard of care". Anyone have any ideas? Thanks in advance.
