However, they are grouped as \u0027N\u0027 for the NADAC calculation since they are generally designated as generic by most State Medicaid programs for the purposes of reimbursement. Another example of this occurrence is when proprietary named drugs, approved under an Abbreviated New Drug Application (ANDA) are appropriately in the CMS Covered Outpatient Drug file as \u0027N\u0027 for the purpose of rebates.
