Medicare began in 1965 as a federal health insurance program for people 65 and older

President Lyndon B. Johnson signed Medicare into law on July 30, 1965. The program started on July 1, 1966. It was created to provide hospital and medical insurance to Americans aged 65 and over, regardless of income or medical history. Before Medicare, many older adults had no health coverage at all, and medical bills were a leading cause of poverty in that age group.

Medicare was part of a larger package of social programs Johnson called the "Great Society." It was built on the foundation of Social Security, which had existed since 1935. The idea was straightforward: the federal government would pool money from workers' payroll taxes and use it to pay for hospital care, doctor visits, and other medical services for seniors.

The program was controversial when it was proposed. Some people argued the government should not run health insurance. Others said it did not go far enough. But Congress passed it with strong majorities in both chambers, and it became law despite the opposition.

Key Takeaways

  • Medicare was signed into law on July 30, 1965, and coverage began on July 1, 1966.
  • The program was created to provide hospital and medical insurance to people 65 and older, a group that often had no coverage before.
  • Medicare was funded through payroll taxes on workers' wages, similar to how Social Security works.
  • The original program had two parts: Part A covered hospital stays, and Part B covered doctor visits and outpatient care.
  • Medicare has been expanded several times since 1966, including the addition of prescription drug coverage in 2006.

How Medicare was structured when it launched

The original Medicare program had two parts. Part A covered inpatient hospital care, including hospital stays, skilled nursing facility care, hospice, and home health services. Part B covered outpatient services: doctor visits, lab tests, X-rays, and other medical services not provided in a hospital.

Part A was funded by a payroll tax on workers and employers — money taken directly from paychecks. Part B was funded partly by premiums that seniors paid themselves and partly by general tax revenue. Seniors had to pay a monthly premium for Part B, and they also paid a deductible and copayments when they used services.

When Medicare started, it covered about 19 million people. That number grew quickly as the population aged and as awareness of the program spread. By 1970, Medicare covered over 20 million beneficiaries.

Why Medicare was created in the 1960s

In the early 1960s, older Americans faced a health care crisis. The average person over 65 had an income of less than $1,000 per year (in dollars of that time), but medical bills averaged $300 to $400 per year — a huge burden. Many seniors had to choose between buying medicine and buying food. Some went without care entirely because they could not afford it.

Private health insurance companies did not want to insure older people because they were expensive to cover — they used more medical services and had more chronic illnesses. Insurance was available, but premiums were very high, and many seniors straightforward could not pay them.

Labor unions, senior advocacy groups, and doctors who treated poor patients all pushed for a government solution. The American Medical Association opposed Medicare, but public support was strong. Polls showed that most Americans, including most seniors, wanted the government to help pay for health care for older people.

Changes to Medicare since 1966

Medicare has been expanded and modified many times since it began. In 1972, Congress added coverage for people under 65 who had been receiving Social Security disability benefits for at least two years, and for people of any age with end-stage renal disease (permanent kidney failure requiring dialysis).

In 1997, Congress created Part C, also called Medicare Advantage. This allowed private insurance companies to offer Medicare coverage as an alternative to the original program. Part C plans often included prescription drug coverage, which the original program did not.

In 2006, Congress added Part D, which is prescription drug coverage. This was a major change because the original Medicare program did not cover most medications. Part D is run by private insurance companies under contract with Medicare.

In 2020, Congress added coverage for telehealth services (doctor visits by video or phone), which became especially important during the COVID-19 pandemic. Medicare continues to cover telehealth visits today.

Who could get Medicare when it first started

When Medicare began in 1966, you had to be 65 or older to get it. You also had to have worked long enough to earn Social Security credits — usually at least 10 years of work. If you had not worked that long, you could still get Medicare by paying a monthly premium, but the premium was higher than for people who had earned credits through work.

Spouses of workers who had earned enough credits could also get Medicare at 65, even if they had not worked themselves. Widows and widowers could get Medicare at 60 if their spouse had earned enough credits.

The program did not cover everyone over 65 at first. People who were not yet 65 had no coverage through Medicare, even if they were disabled or very sick. That changed in 1972 when Congress extended Medicare to younger people with disabilities and to people with end-stage renal disease.

How Medicare changed the American health care system

Medicare's creation was a turning point for health care in America. Before 1966, many older adults delayed or skipped medical care because they could not afford it. After Medicare started, seniors went to the doctor more often, got preventive care, and caught diseases earlier.

Hospital admissions for people over 65 increased sharply in the first few years after Medicare began. Some of this was because people finally had coverage for care they had been putting off. Some was because doctors and hospitals could now be paid for treating seniors, so they had more incentive to admit them.

Medicare also changed how hospitals and doctors were paid. Before Medicare, payment systems varied widely. Medicare created a standardized way to pay for hospital care and doctor services, which influenced how private insurance companies paid as well. Over time, this helped create more uniform pricing across the country.

Medicare enrollment and growth over time

Medicare started with about 19 million beneficiaries in 1966. By 1970, enrollment had grown to over 20 million. By 1980, it was nearly 28 million. By 2000, Medicare covered about 39 million people. Today, Medicare covers more than 66 million beneficiaries, including people 65 and older, younger people with disabilities, and people with end-stage renal disease.

The growth in enrollment reflects both population aging and the expansion of the program to cover new groups. As the Baby Boom generation has reached 65, Medicare enrollment has accelerated. The program is now one of the largest health insurance programs in the world.

Frequently Asked Questions

Did Medicare exist before 1966?

No. Medicare began on July 1, 1966. Before that, there was no federal health insurance program for seniors. Some states had programs to help poor older people pay for medical care, but coverage was limited and varied widely by state.

Was Social Security created at the same time as Medicare?

No. Social Security was created in 1935, more than 30 years before Medicare. Medicare was added later as a separate program to cover health care costs. Both programs are funded through payroll taxes, but they serve different purposes — Social Security provides retirement income, while Medicare provides health insurance.

Could people under 65 get Medicare when it started?

No, not at first. Medicare was only for people 65 and older in 1966. In 1972, Congress expanded the program to include people under 65 who had been receiving Social Security disability benefits for at least two years, and people of any age with end-stage renal disease.

How much did Medicare cost when it started?

The original Part B premium in 1966 was $3 per month. The deductible was $50 for hospital care. These amounts were much lower than what seniors would have paid for private insurance at the time, but they still represented a significant cost for people on fixed incomes. Premiums and deductibles have increased many times since then.

Did all doctors accept Medicare when it started?

Most doctors accepted Medicare, but not all. Some doctors were concerned about government involvement in medicine and refused to treat Medicare patients. Over time, nearly all doctors came to accept Medicare because it provided a reliable way to get paid for treating seniors. Today, the vast majority of doctors accept Medicare.
