Revenues and Profits From Medicare Patients in Hospitals Participating in the 340B Drug Discount Program, 2013-2016.

The federal 340B program lowers the acquisition cost of prescription drugs and places no limits on what hospitals charge payers. Congress established the program to allow 340B profits (the difference between payments and acquisition costs) to subsidize other safety-net services. Little is known about the magnitude of revenues and profits from the 340B program among participating hospitals.
