Medicare keeps denying labs

Hi, I have been taking medicare patients for a while. lately after a local community center went bankrupt, i decided to take a few patients. One current issue I keep having is that medicare keeps denying coverage for labs like cbc, chem panel, lipids, hemoglobin A1c. The labs (quest/labcorp) don't know what it is either other than we have the wrong codes. I am using the standard codes for bipolar/schizophrenia. F31.x, F20.x etc. Anyone else having this issues/have experience with this?
