Medicare was created by Congress in 1965 as part of the Social Security Act

President Lyndon B. Johnson signed Medicare into law on July 30, 1965. The program grew out of decades of debate about how to pay for medical care for older adults. Before Medicare, most people over 65 had no health insurance because private insurers considered them too expensive to cover.

The law passed with bipartisan support in Congress, though the path to it was long. Proposals for government health insurance for seniors had been introduced since the 1950s. What changed in 1965 was a combination of political will, a Democratic majority in Congress, and growing public support for the idea that older Americans should not lose their homes to medical bills.

Key Takeaways

  • Congress passed Medicare in 1965 under President Johnson, creating the first federal health insurance program for people 65 and older.
  • The program was designed to cover hospital care, doctor visits, and other medical expenses that were bankrupting seniors before it existed.
  • Medicare began on July 1, 1966, giving people a few months to sign up after the law was signed.
  • The original program had two parts: Part A for hospital care and Part B for doctor visits, and both are still the foundation of Medicare today.

Why Congress created Medicare in the first place

In the early 1960s, about half of Americans over 65 had no health insurance at all. Medical bills were the leading cause of bankruptcy for older adults. A hospital stay could wipe out a lifetime of savings. Many seniors had to choose between buying medicine and buying food.

The Social Security program, created in 1935, provided a monthly check but it was not enough to cover healthcare costs. Doctors and hospitals charged whatever they wanted, and prices were rising. Private insurance companies would not sell policies to people over 65 because the risk was too high.

Lawmakers from both parties began to see government insurance as the only solution. The American Medical Association opposed it for years, but public pressure grew. By 1965, enough members of Congress believed that healthcare for seniors was a federal responsibility.

How the original Medicare program was structured

When Medicare started on July 1, 1966, it had two parts. Part A covered hospital stays, nursing home care after a hospital stay, hospice, and some home health care. Part B covered doctor visits, outpatient care, and medical equipment. Part A was automatic for anyone 65 or older who had paid into Social Security. Part B was optional and cost a monthly premium.

The program was built on the idea that the federal government would pay hospitals and doctors directly for the care they gave to Medicare patients. Seniors would pay a small amount out of pocket, but the government would cover most of the cost. This was a major shift from the system before, where seniors paid the full bill and hoped they could afford it.

Congress also created Medicaid at the same time, in the same 1965 law. Medicaid was designed for low-income people of any age, while Medicare was only for people 65 and older. The two programs are separate, though they sometimes overlap for people who are both old and poor.

The people who pushed Medicare through Congress

President Johnson made Medicare a centerpiece of his "Great Society" agenda. He believed the federal government had a responsibility to protect older Americans from medical hardship. Johnson had seen poverty and illness firsthand as a young teacher in Texas, and he made healthcare a personal priority.

Senator Ted Kennedy and Congressman Wilbur Mills were key figures in drafting the bill. Mills, a Democrat from Arkansas, chaired the House Ways and Means Committee, which controlled tax and spending bills. He worked with both Democrats and Republicans to build a compromise that could pass.

The American Association of Retired Persons (AARP), founded in 1958, campaigned hard for the law. Labor unions also pushed Congress to pass it, because many of their members were aging and losing coverage when they retired. Doctors and hospitals eventually accepted the program, though many initially opposed it.

What changed after Medicare started

In the first year, about 19 million people signed up for Medicare Part A. Hospitals and doctors had to learn new billing systems. The federal government had to hire thousands of people to process claims and pay bills. It was chaotic at first, but the program stabilized within a few years.

Prescription drug coverage was not part of the original Medicare. Neither was dental or vision care. Congress added Part D (prescription drugs) in 2003, more than 35 years later. Dental and vision are still not covered by standard Medicare, though some supplemental plans offer them.

In 1972, Congress expanded Medicare to include people under 65 who had been on disability for two years, and people of any age with end-stage renal disease. This was a significant change that made Medicare more than just a program for older adults.

How Medicare has grown since 1965

When Medicare started, it cost about $4.5 billion in its first year. Today, Medicare covers about 67 million people and costs hundreds of billions of dollars annually. The program has grown because the population has aged, because medical costs have risen, and because Congress has added new services and expanded who can join.

The structure of Medicare has stayed mostly the same since 1965. Part A and Part B are still the core. Part C (Medicare Advantage) was added in 1997 as an alternative way to get coverage through private insurance companies. Part D was added in 2003 to cover prescription drugs.

Congress has changed Medicare's rules many times over the decades. Deductibles and copayments have gone up. The age to join has stayed at 65, even though life expectancy has increased. Debates about Medicare's future continue today, with disagreement about how to keep it solvent as more people live longer.

Frequently Asked Questions

Did Medicare exist before 1965?

No. Before 1965, there was no federal health insurance program for seniors. Some states had small programs, and some employers offered coverage to retirees, but most people over 65 had no insurance at all. Medicare was the first time the federal government took responsibility for paying for healthcare for a large group of people.

Why did it take so long to create Medicare?

Proposals for government health insurance had been around since the 1930s, but they faced strong opposition from doctors, hospitals, and insurance companies who feared losing money. The American Medical Association spent millions fighting the idea. It took decades of public pressure, changing attitudes about government's role, and the right political moment in 1965 for Congress to finally pass it.

Was Medicare always free?

No. Even in 1966, people had to pay premiums for Part B and had deductibles and copayments for both parts. Part A was free for people who had paid into Social Security, but Part B cost money. Today, premiums, deductibles, and copayments are much higher than they were in 1966.

Could someone refuse Medicare when it started?

Part A was automatic for anyone 65 or older who may have access to through Social Security. You could not refuse it. Part B was optional, so people could choose not to sign up, though most did. Today, Part A is still automatic, but you can delay Part B if you have other coverage.

Has Medicare changed much since 1965?

The basic structure has stayed the same, but Congress has made many changes. New parts have been added, may be able to access has expanded to include younger disabled people, and rules about what is covered have changed many times. The biggest recent change was Part D in 2003, which added prescription drug coverage for the first time.
