It’s easy to forget that before 1966, roughly half of all seniors were uninsured, living in fear that the high cost of health care could propel not only them, but their families, into poverty. Few remember that, not that long ago, far too many disabled people, families with children, pregnant women and low-income working Americans were unable to afford the medical care they needed to stay healthy and productive.

Fifty years ago, on July 30, 1965, the landscape of health care in America changed forever when President Lyndon B. Johnson signed the landmark amendment to the Social Security Act, giving life to the Medicare and Medicaid programs.

Medicare and Medicaid save lives, help people live longer, and provide the peace of mind that comes with affordable health care that’s there when you need it. Chances are, you or someone in your family either has Medicare or Medicaid or you know someone who does. In fact, Medicare and Medicaid cover nearly 1 out of every 3 Americans — that’s well over 100 million people. In Georgia, more than 1.5 million seniors are covered by Medicare, including standalone prescription drug plans. Another 1.8 million, including many working poor – mostly women and children – are insured by Medicaid.

Marking the 50th anniversary of these lifesaving programs gives us an opportunity to recognize and remember the ways they’ve transformed the delivery of health care in the United States. Medicare and Medicaid have greatly reduced the number of uninsured Americans and have become the standard-bearers for quality and innovation in American health care.

No other program has changed the lives of Americans more than Medicare and Medicaid. They provide Americans with access to the quality and affordable health care they need to live happy, healthy and productive lives. Today, about55 million Americans depend on Medicare to cover 23 types of preventive services, including flu shots and diabetes screenings (some of these services are free, and for others you have a small copayment or pay the deductible.) Medicaid provides comprehensive coverage to more than 70 million eligible children, pregnant women, low-income adults and people living with disabilities. It covers essential services like annual checkups, care for new and expecting mothers, and dental care for kids.

Medicare and Medicaid provide more and more Americans with access to the quality and affordable health care they need and deserve. Though they started as basic health programs for people who had no other access to health coverage, Medicare and Medicaid have helped millions get access to care they wouldn’t get otherwise.

If Georgia chooses to expand Medicaid, an additional 389,000 citizens would be covered in 2016.

Across five decades, Medicare and Medicaid have become the standard bearers for coverage, quality and innovation in American health care. Innovative and dedicated teams are combating fraud and working to continually improve the quality of life and care delivered under these programs. Medicare and Medicaid are among the most efficient and well-managed health insurance programs in the world. They will continue to transform to create a health care system that delivers better care, spends health care dollars more wisely and results in healthier people.
