I need information on the United Healthcare Medicare exams. I was told and so was a patient, that UHC allows 2 exams per year that are free to the patient. One is the wellness exam billed with the appropriate G code, and one is a comphrensive physical. How do you bill the comprehensive physical? All UHC will say is that they follow Medicare guidelines. If you bill with standard E&M codes they will have a copay, and Medicare doesn't recognize the 99397 code. Any ideas or experience with this situation?
