President Lyndon B. Johnson signed Medicare into law on July 30, 1965

Medicare was created as part of President Lyndon B. Johnson's Great Society program. Johnson signed the Social Security Act Amendments of 1965 into law on July 30, 1965, at the Harry S. Truman Library in Independence, Missouri. The law established both Medicare and Medicaid. Medicare became effective on July 1, 1966, giving seniors their first federal health insurance program.

The push for federal health insurance for older adults had been building for years. President Harry Truman first proposed national health insurance in 1945, but Congress did not pass it. Throughout the 1950s and early 1960s, advocates argued that seniors faced the highest medical costs but had the lowest incomes. By the time Johnson took office in 1963, public support for a seniors' health program had grown strong enough that Congress was ready to act.

Key Takeaways

  • President Lyndon B. Johnson signed Medicare into law on July 30, 1965, and the program began covering seniors on July 1, 1966.
  • Medicare was created because seniors had high medical costs but often could not afford care, and earlier proposals for federal health insurance had failed.
  • The original Medicare program included Part A (hospital insurance) and Part B (medical insurance), with Part D (prescription drug coverage) added much later in 2006.
  • Congress continues to change Medicare rules and coverage, so what Medicare covers today is different from what it covered when it started.

Why Congress created Medicare in 1965

Before Medicare, most seniors had no health insurance. Private insurance companies either would not sell to people over 65 or charged them prices too high to afford. Studies in the early 1960s showed that seniors spent a larger share of their income on medical care than any other age group, yet had the lowest average income.

The American Medical Association and some insurance companies opposed Medicare, arguing that the government should not run a health program. Despite this opposition, Congress passed the law with strong majorities in both the House and Senate. Johnson framed Medicare as a way to honor the contributions seniors had made to the country through decades of work and taxes.

What the original Medicare program included

When Medicare started in 1966, it had two parts. Part A covered hospital stays, skilled nursing facility care, hospice, and some home health services. Part B covered doctor visits, outpatient care, medical equipment, and some preventive services. Seniors had to pay a monthly premium for Part B, and they paid deductibles and copayments for both parts.

The program did not cover prescription drugs, dental care, vision care, or hearing aids. These gaps in coverage have remained a challenge for seniors ever since. Over the decades, Congress has added new coverage areas — most notably Part D for prescription drugs in 2006 — but large out-of-pocket costs for these services still exist.

How Medicare has changed since 1965

Congress has modified Medicare many times since Johnson signed it into law. In 1972, Medicare coverage expanded to include people under 65 with permanent disabilities and people with end-stage renal disease. In 1997, Congress created Part C (Medicare Advantage), which allows seniors to receive their Medicare benefits through private insurance plans instead of traditional Medicare.

The biggest change came in 2006 when Part D added prescription drug coverage. This was the first major expansion of Medicare benefits in decades. Since then, Congress has made smaller changes to deductibles, premiums, and what services are covered. The program today looks quite different from what it was in 1966, and it continues to change as Congress passes new laws.

The role of other people in creating Medicare

While Johnson signed the law, many others shaped Medicare's creation. Senator Ted Kennedy and Representative Wilbur Mills were key figures in Congress who pushed the legislation forward. Mills, who chaired the House Ways and Means Committee, worked with Johnson's administration to design the program's structure.

Wilbur Cohen, an official in the Department of Health, Education, and Welfare, played a major role in writing the actual Medicare rules and regulations. Social Security Administrator Robert Ball also contributed to the program's design. These officials worked behind the scenes to turn the law into a working program that could serve millions of seniors starting in 1966.

Medicare's place in the history of U.S. health care

Medicare was the first time the federal government directly provided health insurance to a large group of Americans. Before 1965, health insurance in the United States was almost entirely private — either through employers or purchased individually. Medicare changed that model and created a government-run program that has covered seniors for nearly 60 years.

The creation of Medicare also led to the creation of Medicaid, which covers low-income people of all ages. Together, these two programs fundamentally changed how Americans access health care. Today, Medicare covers about 67 million people, making it one of the largest health insurance programs in the world.

Frequently Asked Questions

Did Medicare exist before 1965?

No. Before 1965, there was no federal health insurance program for seniors. Some seniors had private insurance, but most had none. A few states ran their own programs for poor seniors, but these were small and limited.

Why did it take so long to create Medicare?

Presidents and Congress had debated national health insurance since the 1940s. The American Medical Association and insurance companies opposed it. It was not until the 1960s, when public support grew strong and Democrats gained large majorities in Congress, that the law could pass.

Was Medicare always free for seniors?

No. From the start, seniors paid a monthly premium for Part B and paid deductibles and copayments for services. Today, most seniors also pay premiums for Part A if they did not pay Medicare taxes for 40 quarters during their working years.

Has Medicare covered prescription drugs since 1966?

No. The original Medicare program did not cover prescription drugs at all. Part D, which covers prescriptions, was not added until 2006 — 40 years later. Many seniors still struggle with prescription drug costs today.

Can Congress change what Medicare covers?

Yes. Congress has changed Medicare many times since 1965. They can add new services, remove coverage, change how much seniors pay, and change which providers are included. These changes happen through new laws that Congress passes.
