Sen. Charles Grassley (R-IA) sent a letter July 31 to Walgreens requesting detailed information about its role in the significant expansion of contract pharmacies in the 340B program and questioning its compliance with the intent and integrity of the program after reviewing several presentations given by Walgreens employees. The letter includes requests for specific information about the covered entities with which Walgreens has a contract, including a list of all 340B covered entities with which Walgreens has an active contract pharmacy agreement and a summary of all profits generated as a result of participating in the 340B program as a contract pharmacy.
