06111945ccc, I haven't been to lab corp. Babs10's (Thank you Babs) experience may be the answer. Your original Medicare does pay. It is the Advantage Plans that are disadvantaged. It might be that your physician has more sports patients than osteoporosis patients (aside from being young enough not to know the ropes). If you have been denied payment by medicare, there is an appeals process. I'd hand the entire mess to the billing staff at your physician's office. You might have to direct them to the statement of medical necessity. You are covered.
