SUSTAIN 340B Act

The SUSTAIN 340B Act overhauls the federal drug discount program to tighten oversight and prevent fraud by requiring covered entities to register their contract pharmacies and child sites with the Department of Health and Human Services. It establishes a new independent data clearinghouse to track claims and stop duplicate discounts, while also mandating that health insurers and pharmacy benefit managers treat 340B providers on equal footing without imposing discriminatory reimbursement terms. The bill defines strict criteria for what constitutes a valid patient relationship and authorizes a user fee program starting in fiscal year 2031 to fund additional audits and enforcement activities. These provisions directly affect safety-net healthcare providers, drug manufacturers, and insurance companies by increasing transparency requirements and expanding the government's authority to penalize non-compliance.
