I am interested in the billing for PRP injections (0232T). I have been reading your prior posts. We billed the service with an office visit and when the insurance reviewed the claim they upped the value of the E&M stating the procedure would be mutually exclusive. The EOB didn't even list the procedure, leading me to believe they don't recognize the code. We did have the patient sign responsibility but can we still hold the patient responsible since the insurance did not deny as a non covered procedure?
