Good Morning We have been getting denials from Medicare when billing J9190 for CO-50 (Not Medically Necessary). Upon calling Medicare we were told that there is now an internal MUE but they can not tell us what it is. They states this told place starting Jan.1 2011, but we just starting getting denials. Does anyone know what the new MUE is for J9190? Thanks as always for your help.
