Could someone please clarify this. I am seeing in these threads it would not be appropriate. However the codebook states if upper and lower extremity to code twice with modifier 59. I have claims with 3 levels documented (high thigh, low thigh, calf, ankle) bilateral lower extremities and 1 level documented (brachial) bilateral upper extremities. The claims are coded with 93922-59 and 93923. Looking at the codebook I would think that would be correct but reading conversations in the threads here I am getting confused. Any guidance is appreciated!
