Medicare Part D Prescribers - by Provider and Drug

The Medicare Part D Prescribers by Provider and Drug dataset provides information on prescription drugs prescribed to Medicare beneficiaries enrolled in Part D by physicians and other health care providers. This dataset contains the total number of prescription fills that were dispensed and the total drug cost paid organized by prescribing National Provider Identifier (NPI), drug brand name (if applicable) and drug generic name.

Note: This full dataset contains more records than most spreadsheet programs can handle, which will result in an incomplete load of data. Use of a database or statistical software is required.
