How do you identify and recover missing third-party payments and short paid or unpaid claims in the pharmacy? Approximately 95% of prescriptions are billed through a third-party payer (Number of Retail Prescription Drugs Filled at Pharmacies by Payer, 2019) for reimbursement. Payment to the pharmacy for any number of these claims can be short paid or missing which not only affects reconciliation, but negatively impacts your bottom line.
