Charlene hit it right on. 1st - what is the allowed amount from Medicare? 2nd - what is the allowed amount for the secondary? If Medicare paid more than the secondary allowed, it's been paid in full, the secondary and the patient don't owe. HOWEVER, make sure the patient's secondary doesn't have a deductible or co-pay to be met by the patient, if that's the case the patient would have to pay the co-pay to the secondary's allowed amount. Really check the notes on the secondary EOB. Based on what you wrote, Medicare paid the same or more than the secondary's allowed amount.
