How does a physician report performing a Department of Transportation physical?  With CPT® code 99455 and ICD-9 code V70.5,  99455 is for a work related or medical disability examination by the treating physician.  (9945 is for this examination by other than the treating physician.)  See the CPT® book for the complete description of the code. 

It is incorrect to bill a preventive medicine code for this service, in the 99381-99397 series of codes.  This service is not payable by the patient's insurance company, which does not cover employment related expenses.  Billing with a preventive medicine service, and a general exam diagnosis code, V70.0, so that the insurance company pays the service, is incorrect.
