Part of an ongoing effort to provide more transparency and health care data, the White House recently announced a new tool called the Medicare Drug Spending Dashboard. The tool provides public information about how much money is spent on prescription drugs in Medicare Part B and Part D. The tool can be used to learn key facts about prescription drug spending, including the top Part D prescription drugs with the highest total spending, medicines with the largest percent increase in price, and prescription drugs with the highest cost-sharing for beneficiaries.
