We bill 20610 all the time to Humana and Medicare with many different Dx codes but all of a sudden Humana is denying then when billed with dx M67.811 and all the other codes in that dx family. I have checked the CMs website and there isn’t a LCD code listing for this cpt. Can any one help me?? Have called Humana but I find whenever I call them it is a waste of my time and don’t get clear information that makes any sense.
