Our office has always coded our EKG as a 93000, we do the ekg and interpretation always on the same day. However, UHC recently sent back an eob and they changed the 93000 to a 93005 and 93010. Has anyone else run into this? It confuses me because if a 93010 and 93005 are on the same claim it is a 93000, just as we billed. Please help!
