Medicaid Exclusion File
Use the Medicaid Exclusion File function on the 340B Reports/Files page to generate a list of Medicaid Provider Numbers and NPI Numbers for covered entities that have indicated to OPA that they are billing Medicaid for drugs purchased at 340B prices.
Duplicate Discount Prohibition provides more information about why the Office of Pharmacy Affairs needs to know whether the entity intends to fill Medicaid prescriptions with 340B-purchased drugs.
