Medicare has denied procedure code 81000 as missing/incomplete/invalid referring
provider primary identifier. We are the patients primary care physician. We did the
urine dip stick as the patient was having symptoms of a urinary tract infection.
I have called Medicare and they were so rude! The rep told me that I need to call another
number which she provided, but when I called it was an automated service that gave me
the same information on the Medicare EOB.
