This year's Fortune 500 companies have a total of $13.8 trillion in revenue, equivalent to roughly two-thirds of the U.S. gross domestic product.

Fortune sorted companies on the list based on their sector. Within the health care sector, Fortune sorted companies based on different health care industries, including wholesalers, insurance and managed care, medical products and equipment, and pharmaceuticals.  

Many health systems are organized as nonprofits, which are not eligible for inclusion on the Fortune 500.
