So the 73630 RT FY TC was denied stating "unprocessable"? Is that the only denial information? The FY should only be on the TC portion of the xray and I don't see where it matters if it's in the first location or the second. I would first check to see if there is any other denial codes. If not, I would call and ask for additional explanation of the denial. They may be able to point you to an LCD or NCD. To me it appears to be coded correctly.
