Preventive, Breast Pelvic, and Pap for Medicare Patient

One of our coders made the point that our providers' document a preventive service plus a breast/pelvic exam (G0101) and a pap (Q0091) for Medicare patients. Her experience is that the preventive can still be billed although not payable by Medicare. If the patient has a secondary such as a Medicare Advantage Plan, they often pick up the preventive. Just wondering if others have similar experience/knowledge? From a documentation perspective, I would agree this is correct coding.

Thank you
