I just recently started having Medicare down code my ENG testing, normally i would code the 92541 with 3 units and 92542 with 2 units. Medicare is only paying for 1 unit and wants me to appeal why there are 3 units for the 1st and 2 units for the 2nd code. Is anyone having this problem? When i ask the audiologist why they are coded this way no one can answer that for me, they just say that it is routine. Can someone help me?
