Health & Welfare Benefit Administration

While health care reform makes health care coverage available to millions of Americans, it creates a significant administrative challenge for employers. Sharply rising health care costs and growing complexity and regulations are forcing many U.S. employers to take a hard look at how they deliver health care to employees. More and more, they're outsourcing health and welfare administration—controlling costs, enabling movement toward consumer-driven health care, ensuring that increasingly demanding compliance requirements are met and freeing staff to focus on HR programs that drive growth.

Aon Hewitt is the leader in outsourced health and welfare delivery, handling the administration of health care for more than 9 million employees and retirees. From designing the very first flex plan to pioneering today's cutting-edge, consumer-driven health plans, we have a long track record of innovation and industry firsts in our 27 years delivering health and welfare services to our clients.
