I continue to receive so much contradictory information on 64612 & 64613. BCBS refuses to pay more than 1 of each of these codes per day. I'm trying to get clarification on Medicare guidelines. Am I correct in saying Medicare allows 64612 Rt & Lt - each side of the face separately. However, 64613 & 64614 do not allow for Rt & Lt even if both sides of neck or trunk are done. Does anyone have any advise on this subject? Thank you in advance for info!!
