To initiate data history, which entities must submit the one-time batch submission?

• A. Only in-state pharmacies
• B. All pharmacies in Montana
• C. Each certified Pharmacy and out-of-state mail service Pharmacy
• D. Only pharmacies currently dispensing controlled substances

Answer: (C)

Starting data history hinges on creating a complete baseline in the prescription monitoring program by collecting past dispensing records from every entity that reports data. In Montana, that means submitting a one-time batch from each certified pharmacy and from out-of-state mail service pharmacies. These are the reporting entities authorized to feed dispensing data into the system, including those that operate across state lines but serve Montana patients. Providing this historical batch ensures the PDMP starts with a full view of past controlled-substance activity, which is essential for accurately identifying unusual or risky patterns later on. It isn’t limited to in-state pharmacies, nor to all Montana pharmacies regardless of reporting status, and it isn’t limited to pharmacies currently dispensing—past data from the reporting entities is what establishes the baseline.
