Medicine Assistance Tool (MAT) matches patients with resources and cost-sharing programs that may help lower out-of-pocket medicine costs, whether or not you have insurance. MAT provides a search engine designed to help patients, caregivers and health care providers learn more about the resources available through the various biopharmaceutical industry programs. MAT is not its own patient assistance program, but rather a search engine for patient assistance resources offered by the biopharmaceutical industry.
