Since 1999, RxI Services has reviewed more than $2 billion in specialty physician and oncology claims to identify and validate actual physician orders and units of medication when indicated. This validation process allows auditors to perform exact pharmaceutical calculations, reconcile correct product and package size and verify correct units of high-cost drugs billed. Once correct orders and units are validated, claims can be priced accurately for any variety of applicable fee schedules or reimbursement methodologies.
