We have a patient that was given an administration of Cimzia in both left and right thigh. We billed the CPT code with 2 units but are only getting paid for one and the other unit is denying as inclusive. Should this have been billed 96401 x 1 unit and 96401 x 1 with modfier 76 or 96401 x1 unit modifier 76/59? Please advise. Thanks
