US Patent 11170394 Parallel processing for pharmacy fulfillment

Methods and systems for managing pricing guarantees for prescription drugs are described. In one embodiment, a target prescription drug discount guarantee associated with a pharmacy benefit manager client is accessed. A prescription drug discount associated with a plurality of prescription drug claims associated with the pharmacy benefit manager client is calculated to obtain a calculated prescription drug discount. A difference between the target prescription drug discount guarantee and the calculated prescription drug discount is determined. A prescription drug pricing schedule associated with the pharmacy benefit manager client is modified based on the difference between the target discount guarantee and the prescription drug discount to create a modified prescription drug pricing schedule. Other methods and systems are described.
