Medicare Part D Drug Spending Dashboard

Medicare Part D Drug Spending Dashboard & Data

The Medicare Part D Drug Spending Dashboard is an interactive, web-based tool that presents spending information for Medicare Part D drugs - drugs patients generally administer themselves and that are paid through the Medicare Part D program. Part D drug information is available from the Part D Prescription Drug Event (PDE) data, which are available for a subset of Medicare beneficiaries who choose to enroll in Part D (which represents approximately 70% of Medicare beneficiaries).

The Dashboard focuses on average spending per dosage unit and change in average spending per dosage unit over time. Dosage units refer to the drug products in the form in which they are marketed for use, e.g. number of tablets, grams, milliliters or other units. The tool also displays spending information for manufacturer(s) of the drugs as well consumer-friendly information of drug uses and clinical indications.

Drug spending metrics for Part D drugs are based on the gross drug cost, which represents total spending for the prescription claim, including Medicare, plan, and beneficiary payments. The Part D spending metrics do not reflect any manufacturers’ rebates or other price concessions as CMS is prohibited from publicly disclosing such information. However, high-level rebate summary information is available for 2014 (PDF). All Part D organization and plan types are included, while over-the-counter drugs in the PDE data are excluded.

Additional drug metrics and the most recent five years of data are available for download in Excel.
