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

Medicare was created under President Lyndon B. Johnson as part of his "Great Society" domestic agenda. Johnson signed the Social Security Act Amendment—the legislation that established Medicare—on July 30, 1965, at the Harry S. Truman Library in Independence, Missouri. Truman, the former president who had first proposed national health insurance in 1945, was present at the signing ceremony.

The program began on July 1, 1966. At that time, it covered hospital insurance (Part A) and medical insurance (Part B) for people age 65 and older. The creation of Medicare followed years of debate in Congress, with supporters arguing that older Americans faced steep medical costs and many could not afford care.

The political path to Medicare

The road to Medicare took nearly two decades. President Harry S. Truman proposed a national health insurance program in 1945, but Congress rejected it during the Cold War era, when many viewed government health programs with suspicion. The idea lay dormant through the 1950s.

When Johnson took office in 1963, he made healthcare for seniors a priority. Democrats controlled both chambers of Congress by a wide margin after the 1964 election, giving Johnson the votes he needed. The House Ways and Means Committee, led by Representative Wilbur Mills, drafted the legislation. Mills combined three separate proposals into a single bill: hospital insurance for seniors, voluntary medical insurance, and a program for low-income elderly people (which became Medicaid).

Congress passed the bill in July 1965 with bipartisan support, though Republicans and conservative Democrats raised concerns about government spending and the role of federal programs. The final vote in the House was 307 to 116 in favor.

What Medicare covered when it started

On July 1, 1966, Medicare began with two main parts. Part A covered inpatient hospital care, skilled nursing facility care, hospice care, and some home health services. Part B was a voluntary program that covered doctor visits, outpatient care, and other medical services. People age 65 and older could enroll.

Part B required a monthly premium, which was $3 in 1966. The federal government paid the other half of the cost. Enrollment was not automatic; people had to sign up during an enrollment period. About 19 million people were covered by the end of 1966.

The program did not cover prescription drugs, dental care, vision care, or hearing aids. These gaps have remained part of Medicare's structure, though prescription drug coverage (Part D) was added in 2006.

How Medicare expanded after 1965

Medicare has grown significantly since Johnson signed it into law. In 1972, Congress lowered the age of may be able to access to include people with end-stage renal disease (kidney failure) and some people under 65 with disabilities. This was the first time Medicare covered anyone younger than 65.

In 1997, Congress created Part C, also called Medicare Advantage, which allows beneficiaries to receive their Medicare benefits through private insurance plans instead of traditional Medicare. In 2006, Part D was added to help pay for prescription drugs.

Today, Medicare covers more than 66 million people, including those age 65 and older, younger people with disabilities, and people with end-stage renal disease. The program remains one of the largest health insurance programs in the United States.

Why Johnson chose to create Medicare

Johnson believed that older Americans deserved healthcare security. In the early 1960s, surveys showed that many seniors skipped doctor visits or did not fill prescriptions because they could not afford them. Hospital stays could wipe out a family's savings. Johnson saw Medicare as a moral obligation and a way to reduce poverty among the elderly.

Johnson also framed Medicare as an extension of Social Security, which had been created under President Franklin D. Roosevelt in 1935. By attaching Medicare to Social Security, Johnson made it seem like a natural continuation of a program Americans already trusted. This strategy helped overcome some political resistance.

The creation of Medicare reflected a broader shift in American politics during the 1960s toward federal programs that addressed social problems. Johnson's Great Society included not only Medicare but also Medicaid, the Civil Rights Act, the Voting Rights Act, and programs to fight poverty and improve education.

The debate over Medicare then and now

When Medicare was proposed, opponents warned that it would be too expensive, that it would interfere with the doctor-patient relationship, and that it represented an overreach of federal power. The American Medical Association ran advertising campaigns against it. Some of these arguments continue today, though Medicare has become widely accepted.

Supporters argued then—and argue now—that without Medicare, millions of older Americans would go without care. They pointed out that private insurance companies did not want to cover seniors because they were expensive and high-risk. Only the federal government, they said, could pool the risk across the entire population and make coverage affordable.

Today, Medicare is one of the most popular government programs. Surveys show that both Democrats and Republicans support it, though they may disagree about how it should be funded or reformed.

Frequently Asked Questions

Did any president before Johnson try to create Medicare?

President Harry S. Truman proposed a national health insurance program in 1945 that would have covered all Americans, not just seniors. Congress rejected it. No president before Johnson successfully created a federal health insurance program, though some states had their own programs.

Was Medicare created as a temporary program?

No. Johnson and Congress designed Medicare as a permanent program. It was intended to be part of the Social Security system and to grow as the population aged. It remains in place today, more than 50 years later.

How much did Medicare cost when it started?

The exact cost varied by year and by how you measure it. In its first year of operation (1966), Medicare spent roughly $3 billion. Costs have grown significantly since then as the number of beneficiaries increased and medical care became more expensive.

Could someone refuse Medicare when it started?

Part A (hospital insurance) was automatic for people age 65 and older who were may be able to access. Part B (medical insurance) was voluntary, and people had to sign up and pay a monthly premium. Some people chose not to enroll in Part B, though most did.

Has Medicare changed since Johnson created it?

Yes. Congress has expanded it several times—lowering the age for some people with disabilities, adding prescription drug coverage, and creating private plan options. The structure and benefits have evolved, but the basic idea of federal health insurance for seniors remains the same.
