Medicare Part D

" The Medicare prescription drug program, known as Medicare Part D, provides a voluntary outpatient prescription drug benefit for Medicare beneficiaries. Beneficiaries may choose Part D plans from among multiple plans offered by private companies-plan sponsors-that contract with CMS. Plans may differ in their premiums and cost-sharing arrangements, the drugs they cover, and the pharmacies they contract with to fill prescriptions. CMS developed the Medicare Plan Finder interactive website in 2005 as a tool to help beneficiaries compare Part D plans and identify plans that meet their needs. For Plan Finder to serve its intended purpose, beneficiaries and their advisers need to be able to obtain accurate drug cost information, understand plan options, and navigate the website effectively. GAO was asked to review CMS's efforts to ensure that beneficiaries can use Plan Finder effectively. This report examines (1) how CMS oversees the accuracy of drug pricing information in Plan Finder; and (2) how CMS assesses the usability of Plan Finder and any steps CMS has taken to improve it. To conduct this work, GAO reviewed documentation detailing CMS's processes for overseeing Plan Finder pricing accuracy and obtained data on agency compliance actions. GAO also interviewed CMS officials and organizations that help Medicare beneficiaries navigate Plan Finder"
