In 1992, Congress extended to safety-net providers the same kind of relief from high drug costs that Congress provided to the Medicaid program with the Medicaid rebate law. In particular, Congress enacted Section 340B of the Public Health Service Act (created under Section 602 of the Veterans Health Care Act of 1992). Section 340B requires pharmaceutical manufacturers to enter into an agreement, called a pharmaceutical pricing agreement (PPA), with the HHS Secretary. Under the PPA, the manufacturer agrees to provide front-end discounts on covered outpatient drugs purchased by specified providers, called "covered entities," that serve the nation's most vulnerable patient populations. According to congressional report language, the purpose of the 340B program is to enable covered entities “to stretch scarce federal resources as far as possible, reaching more eligible patients and providing more comprehensive services."
