Is it "legal" to rebill a claim that was denied for being non covered with a code that you know will be covered. Example: Patient comes in for a physical and you bill a physical procedure with a V70.0. Claim is denied because patient does not have preventative coverage. So doctor wants to rebill with an E/M code , say 99215 with symptom diganosis'. Or another scenario: patient is seen for a particular symptom that isnt covered and doctor wants to rebill with a previous diagnosis that he didnt actually see the patient for at that time, but has in the past. ( I think I already know what the answer is....)
