Hi Guest! Great question. We have actually seen different medical insurers process these differently! As you mentioned, some medical insurers prefer the units to be correlated with the quadrants (i.e. 2 units of 21210 for UR and UL quadrants), while we have seen some prefer it to be billed as 1 unit. We recommend using the JO qualifiers to indicate the quadrants on the line item. Hope this helps! What about Medicare? I have found they deny mutually inclusive if you bill 2 units. I have also heard others tell scary stories about audits involved with billing 2 units of bone grafting and not only 1. My doctor is concerned that he will get in trouble for billing 2 units.
