If NADAC is updated monthly, and a drug has a price change before the next monthly NADAC file is published, can states backdate NADAC in order to reimburse pharmacy providers correctly?

The NADAC files have weekly updates posted on Medicaid.gov that reflect any price changes that have occurred since the last posted monthly file. States using the NADAC for their AAC reimbursement methodology will have access to the weekly updates of the NADAC to ensure pharmacies are reimbursed with the most updated NADAC pricing.
