Medicare started because older Americans had almost no way to pay for medical care
Before 1965, most people over 65 had no health insurance. Private insurance companies would not sell to them because older people get sick more often and cost more to treat. Seniors who got sick faced a choice: spend their savings on medical bills or go without care. Many lost their homes paying for hospital stays. Younger people with jobs got insurance through their employers, but retirees had nothing.
President Lyndon B. Johnson signed Medicare into law on July 30, 1965. The program began on July 1, 1966. It was built on the idea that people who had worked their whole lives should not lose everything if they got sick in old age. Congress created it as a social insurance program — meaning people paid into it through payroll taxes while working, then drew benefits when they turned 65.
Key Takeaways
- Before Medicare, most seniors had no health insurance because private companies refused to insure people over 65.
- Medical bills were the leading cause of bankruptcy for older Americans, and many lost their homes to hospital costs.
- Medicare was created as a social insurance program funded by payroll taxes, not charity or means-tested welfare.
- The program began with hospital insurance (Part A) and doctor visit insurance (Part B), and has expanded since then.
The medical crisis that forced Congress to act
In the early 1960s, surveys showed that one in four seniors lived below the poverty line. Many worked their entire lives but had no retirement savings. When they turned 65 and stopped working, they lost their employer health insurance. A single hospital stay could wipe out a year's worth of Social Security checks.
Charities and churches tried to help, but they could not cover the scale of the problem. Some states ran their own programs for poor seniors, but they were small and had long waiting lists. Doctors and hospitals often provided free care to seniors who could not pay, which meant hospitals raised prices on everyone else to make up the difference. The system was broken for everyone — patients, doctors, and hospitals alike.
Labor unions and senior advocacy groups pushed Congress for years to create a national solution. They argued that the country could afford to insure its elderly citizens, and that doing so was a moral obligation to people who had built the nation's economy.
How the program was designed to work
Medicare was modeled on Social Security — a program that was already working and trusted by the public. Like Social Security, it was funded through payroll taxes. Workers and employers each paid a percentage of wages into a Medicare trust fund. When someone turned 65, they became may have access to to benefits based on their work history, not based on how much money they had.
The original program had two parts. Part A covered hospital stays, skilled nursing care, and hospice. Part B covered doctor visits, outpatient care, and medical equipment. People paid a small monthly premium for Part B, but Part A was free to anyone who had paid Medicare taxes for at least 10 years.
Congress chose 65 as the may be able to access age because that was when Social Security began. It was not based on when people actually got sick — it was straightforward the age when retirement benefits started. That age has not changed since 1965, even though life expectancy has increased.
What Medicare did not cover, and why
From the start, Medicare had gaps. It did not cover prescription drugs, dental care, vision care, or hearing aids. It did not cover long-term nursing home care. These gaps existed partly because Congress wanted to keep the program's cost down, and partly because the technology and treatments available in 1965 were different from today.
The program also required seniors to pay deductibles and copayments — meaning they still had to pay money out of pocket for some care. This was intentional. Congress wanted to discourage unnecessary doctor visits while still protecting people from catastrophic bills.
Over time, Congress added coverage for some of these gaps. Prescription drug coverage (Part D) was added in 2006. But major gaps remain. Many seniors still pay thousands of dollars per year for medications, dental work, and long-term care.
How Medicare changed after it started
Medicaid was created at the same time as Medicare, in 1965. While Medicare is for people 65 and older, Medicaid is for people with low incomes of any age. Together, the two programs were meant to cover the most vulnerable Americans.
In 1972, Congress expanded Medicare to cover people under 65 who had been on disability for two years, and people with end-stage renal disease. In 1983, Congress changed how hospitals were paid — instead of billing for each service, hospitals now received a fixed payment per diagnosis. This was meant to control costs, but it also changed how hospitals operated.
In 1997, Congress created Medicare Advantage (Part C), which allowed private insurance companies to offer Medicare coverage as an alternative to traditional Medicare. This gave seniors a choice between the government program and private plans, though the private plans had to cover at least what traditional Medicare covered.
Why the program still matters today
Medicare now covers nearly 68 million people — not just seniors, but also younger people with disabilities and people with kidney failure. It is one of the largest insurance programs in the world. Without it, millions of older Americans would face the same crisis that seniors faced before 1965: the choice between medical care and financial ruin.
The program is not perfect. It has gaps in coverage, and premiums and out-of-pocket costs have risen over time. But the basic idea remains: people who worked and paid taxes should not lose their homes because they got sick in old age.
Frequently Asked Questions
Did Medicare solve the problem of seniors going bankrupt from medical bills?
Medicare reduced the problem significantly, but did not eliminate it. Before Medicare, medical bills were the leading cause of bankruptcy for seniors. Today, medical debt is still a major problem for older Americans, partly because Medicare has gaps in coverage and partly because healthcare costs have risen faster than Medicare benefits.
Why did Congress choose 65 as the age for Medicare?
Congress chose 65 because that was already the age when Social Security retirement benefits began. It was a convenient match with an existing program, not based on medical research about when people actually need more healthcare. The age has remained 65 since 1965.
Was Medicare supposed to cover everything?
No. Congress intentionally left gaps in coverage — for prescription drugs, dental care, and long-term nursing home care — to keep costs down. The program was meant to protect people from catastrophic bills, not to cover every medical expense. Seniors were always expected to pay some costs out of pocket.
Could private insurance companies have solved this problem instead of the government?
Private insurance companies refused to insure seniors before Medicare because older people cost more to treat. A private market solution would have left many seniors uninsured. Medicare was created because the private market had failed to serve this population.
