My understanding of 31535 is that I code each time for a biopsy that was done for each anatomical site ie, if a bx was done of the RT valleculla and epiglottis, then two codes 31535, 31535-59 BUT if two bxs were done of the right vallecula (same anatomical site), then it would be one 31535. Is this correct? Thank you for your help!
