340B Drug Discount Program: Increased Oversight Needed to Ensure Nongovernmental Hospitals Meet Eligibility Requirements, Report to Congressional Requesters [open pdf - 10MB]
From the Highlights: "The number of nongovernmental hospitals participating in the 340B Program has grown over time. HRSA [Health Resources and Services Administration] requires participating hospitals to register and annually recertify their eligibility. HRSA also reviews hospitals' eligibility through audits of a small sample each year. GAO [Government Accountability Office] was asked to provide information on 340B-participating hospitals' contracts with state and local governments. This report (1) describes any obligations in selected nongovernmental hospitals' contracts to serve low-income individuals, and (2) examines HRSA's processes to assess nongovernmental hospitals' eligibility."
