GAO Report: Federal Oversight of Compliance at 340B Contract Pharmacies Needs Improvement

To have their drugs covered under Medicaid, the “340B” program requires drug manufacturers to sell outpatient drugs to covered entities—certain hospitals and clinics—at a discount. These entities are increasingly contracting with pharmacies to dispense 340B drugs. Doing so can make it harder to ensure compliance with 340B rules. For example, contract pharmacies may also fill prescriptions for the general public, increasing the risk of dispensing 340B drugs to ineligible patients.
