We have had a patient's "routine" lab work denied when billing diagnosis code V72.62. When I called Anthem BCBS they said that the patient does have routine benefits but the code I used is not payable. They said they follow the US Preventive Task Force guidelines and these could be found on their website. I looked on the USPTF website and could not find anywhere where they list acceptable routine diagnosis codes. Has anyone ever heard of this or guide me here? Thanks
