Prescription numbers (PC058) are generated by the point of sale systems at the individual pharmacies. Therefore, the same prescription number can be found on claims for different members (PC001+PC107) and pharmacies (PC020). To understand and track the progression of prescription fills across time, group the prescription number (PC058), pharmacy (PC020) and member (PC001+PC107) then sort by paid date (PC017) and/or fill date (PC032). Unlike medical claims, the pharmacy claim number (PC004) and claim line (PC005) should be included with caution because prescription fills and refills are usually considered separate claims and have different claim numbers.
