Complaint Review: Quest diagnostics

My doctor ordered routine labwork on me, to include a urinealysis. A week later I get a bill from Quest Diagnostics for $600.00. A note included said " Perhaps your doctor forgot to inform you a lab specimen had to be sent out of town to be tested. OK, this sounded very suspicious. I am a Registered Nurse, and Lubbock is a major medical center with a University of Texas medical school. There is no lab test known to medical science that cannot be run here. I looked up the code on the bill and it was for a urine culture. I then looked up medicare rules on billing. It is illegal for a laboritory to run one test on the basis of another without an order from the doctor. The doctor did not ask for a urine culture. For one thing this would indicate a bladder or urinary tract infection ( extremely rare in men ).And I did not have either one. I sent the bill back with my own note. I quoted the federal law and told them I was forwarding a copy to the medicare fraud dept. I never heard from them again.
