Medicare History

Medicare was signed into law July 30, 1965, in a bipartisan effort to provide health care coverage for millions of older Americans. Over its 55-year history, the program has grown to include people with permanent disabilities. It’s also added drug coverage, private insurance options and free preventative services.

History of Medicare

Medicare, established in 1965, provides health insurance to Americans aged 65 and older and to younger people with disabilities.

The federal program has evolved significantly over time to give more Americans access to the quality and affordable health care they need.

From its inclusion of people with long-term disabilities in 1972 to the creation of Medicare Part D drug coverage in the early 2000s, Medicare continues to adapt to a changing health care landscape.

More than 62 million people are now enrolled in Medicare, and it remains one of the country’s most popular federal programs.

Early Attempts at National Health Insurance

Discussions of a federal health care system began decades before Medicare’s inception.

In the 1930s, President Franklin Delano Roosevelt decided not to add health care to his Social Security proposal because he feared it would be too controversial and might hinder the passage of other legislation.

President Harry Truman picked up the fight during his administration and took things a step further with a plan to protect a greater number of Americans.

Medicare for All may seem like a new idea, but Truman proposed national health insurance for every American in 1945, and again in 1949.

Millions of our citizens do not now have a full measure of opportunity to achieve and enjoy good health. Millions do not now have protection or security against the economic effects of sickness. The time has arrived for action to help them attain that opportunity and that protection.
Harry Truman’s 1945 speech to Congress

Truman insisted that he was not in favor of “socialized medicine” noting that “the American people want no such system.”

But like modern efforts to expand the federal government’s role in health care, Truman’s attempts were met with staunch opposition.

The American Medical Association and other special interest groups launched expensive lobbying campaigns to kill the bill.

The efforts were successful. By 1950, Truman’s latest proposal was dead.

The idea of a smaller, more targeted program for people aged 65 and older began to emerge in the late 1950s.

Several Democrats introduced legislation that focused on giving elderly Americans health care benefits funded with payroll taxes and overseen by the Social Security Administration.

The media dubbed these proposals Medicare.

The idea gained momentum as organized labor unions backed the proposal. By 1960, presidential candidate John F. Kennedy publicly endorsed the idea.

That same year, the Kerr-Mills Act was signed into law. It created a new means-tested program known as Medical Assistance for the Aged. It also provided federal grants to states that covered health care costs for low-income seniors.

At the time, it was considered a good compromise.

However, three years later, less than 1 percent of older Americans were covered, only 32 states had implemented the legislation and large coverage discrepancies existed across the country.

Kennedy wanted Congress to take bolder action.

“The fact of the matter is that what we are now talking about doing, most of the countries of Europe did years ago,” Kennedy said at a 1962 New York rally. “We are behind every country, pretty nearly, in Europe, in this matter of medical care for our citizens.”

Kennedy never saw the vision realized, but his successor, Lyndon B. Johnson, made Medicare a reality just three years later.

Signing Medicare into Law

When Johnson was elected in 1964, he was determined to pass sweeping social reforms on level with the New Deal.

Health insurance for seniors was at the top of his list.

“Our older people are likely to be hospitalized three times as often as younger people, but their income is less than half of that for people under 65,” Johnson said during a White House briefing January 1964.

On July 30, 1965, Johnson signed Medicare into law at a public ceremony in Independence, Missouri. Former President Truman was by his side.

After signing the Social Security Amendments of 1965, Johnson turned to Truman, now 81, and proclaimed him “the real daddy of Medicare.”

Truman also became the first person to enroll in the program.

Once the festivities ended, the real work began.

Wilbur Cohen, undersecretary of Health, Education and Welfare, said the task of enrolling millions of Americans into the new system in less than a year was like planning the invasion of Normandy.

“We did a better job of preparation than we did for almost any other program,” Cohen said.

When Medicare services launched July 1, 1966, more than 19 million Americans aged 65 and older enrolled.

We think this program is just. We think this program is necessary. We think this program makes sense. And we think this program is going to be the law of the land.
President Lyndon Johnson at a White House press briefing January 15, 1964 — a year-and-a-half before the passage of Medicare.

Prior to its creation, only about half of people over age 65 had health insurance.

Medicare rapidly shrank the number of elderly citizens lacking access to hospitals and doctors in the United States.

It also played a unique role in the civil rights movement.

The year prior to Medicare’s passage, the Civil Rights Act of 1964 had barred federal funding from institutions that discriminated based on race.

Because Medicare was the first national health care program, Southern hospitals were forced to integrate or risk losing funding. Field inspectors visited hospitals to ensure compliance.

It proved to be a powerful motivator.

It’s estimated that more than 1,000 hospitals in the South integrated in less than four months following Medicare’s passage.

The original 1965 amendments to the Social Security program consisted of three parts — hospital insurance financed by payroll taxes, doctor coverage paid for by individual premiums and state grants to be used for the nation’s poorest residents. This last part became the modern Medicaid program.

Today, Medicare Part A pays for a portion of hospital stays, some home health care, skilled nursing facilities and hospice. Most people don’t pay a monthly fee, or premium, for Part A because it’s funded by payroll taxes.

Medicare Part B covers doctor visits and other services. Everyone is required to pay a premium for Part B or, in the case of qualifying low-income individuals, have premiums paid on their behalf by state agencies.

Medicare Continues to Evolve

In 1972, Medicare eligibility was extended to people under age 65 with long-term disabilities and individuals with end-stage renal disease.

The idea was to provide a fallback for people who carry substantial medical expenses but who are unable to get insurance through their employers.

By 2020, 8.5 million younger people received Medicare coverage for the disabled, or about 13.6 percent of all beneficiaries.

History of Medicare Advantage and Private Insurance

Private Medicare health insurance plans have existed in some form since the 1970s. At that time, only health maintenance organizations, or HMOs, were available.

The modern Medicare Advantage program was first established as Medicare+Choice, or Part C, by the Balanced Budget Act of 1997.

The law overhauled the previous payment formula and updated the risk-adjustment model. In an attempt to reduce spending, it also lowered payment rates to private plans.

The law created several new plan options, including preferred provider organizations, provider-sponsored organizations, private fee-for-service plans and high-deductible plans with medical savings accounts.

Medicare+Choice Was Intended to Fulfill Three Goals:
  1. Reduce government cost
  2. Expand choices for consumers
  3. Enhance health care quality

However, the program was considered unsuccessful.

The reduced payment rate caused a wave of plans to exit the program.

In 2000, of the existing participating plans, 99 withdrew, affecting 327,000 people. In 2001, withdrawals and service area reductions affected about 934,000 enrollees.

Insurers cut extra benefits and increased cost-sharing among members as the free market adjusted to the change.

Did You Know?
On Jan. 1, 1998, the website launched.

Enrollment in Medicare+Choice plans dropped nearly 30 percent between 1999 and 2003. Meanwhile, the average premium across all private plans skyrocketed 260 percent from 1999 to 2001.

In 2003, Medicare+Choice was modified under a new law and renamed Medicare Advantage.

The new law significantly raised payments to private plans to counter the effects of the Balanced Budget Act. Medicare began offering rates that were at least as high as Original Medicare spending per enrollee.

A new bidding process was also established where every plan submits a bid representing its estimated cost of providing basic Medicare benefits to enrollees for the coming year.

The private Medicare insurance market boomed in response, and enrollment continues to grow.

From 2010 to 2017, Medicare Advantage enrollment increased more than 70 percent.

By 2023, nearly half of all Medicare beneficiaries — or 30 million people — were enrolled in Medicare Advantage plans, according to the Kaiser Family Foundation.

Today, Medicare Advantage plans are required to provide at least the same benefits as Original Medicare. They often bundle coverage for other services — including prescription drugs, dental and vision — into a single plan.

Medicare Part D Launches

In 2003, President George W. Bush signed the Medicare Prescription Drug, Improvement, and Modernization Act, or MMA.

Many experts consider it the largest overhaul to Medicare since the program’s inception.

The MMA established Medicare Part D, which provides millions of seniors with prescription drug coverage through a complex system of subsidies to private insurance companies. Beneficiaries also pay into the program with monthly premiums.

For beneficiaries with limited resources, the Social Security Administration and CMS work together to provide special low-income subsidies.

Did You Know?
In July 2001, the Health Care Financing Administration was given its current designation, the Centers for Medicare & Medicaid Services, or CMS.

The Part D program was phased in and went into full effect Jan. 1, 2006.

One key provision of the law has remained controversial. The legislation did not allow the federal government to negotiate drug prices. Instead, it explicitly states that only insurance companies administering Medicare prescription drug programs have the legal right to negotiate drug prices directly with manufacturers.

As drug prices soared, the provision stood out as a potential barrier to lower consumer costs because the government was unable to leverage its purchasing power with pharmaceutical companies.

Repealing the provision has broad public support, with a 2015 Kaiser Family Foundation poll showing 88 percent of Americans holding a favorable view of the idea.

Over the years, members of Congress have proposed multiple bills to revise this provision — with no success.

Affordable Care Act Grants Free Preventative Services to Medicare Users

President Barack Obama signed the Affordable Care Act into law March 23, 2010.

The sweeping health care reform added many preventative services to Medicare coverage — including exams, shots, lab tests and screenings.

These services are offered to beneficiaries for free with no deductible, copayment or coinsurance.

Free Medicare preventative services added by the ACA include:
  • An annual wellness visit
  • Cancer screening tests, such as mammograms and colonoscopies
  • Diabetes screening and self-management training
  • Tobacco cessation counseling
  • High cholesterol and high blood pressure screenings
  • A Welcome to Medicare visit
  • Flu and pneumonia shots
  • STD and HIV testing

Eliminating cost barriers for preventative services has three primary goals: Improve people’s short- and long-term health outcomes, increase workplace productivity and reduce the nation’s health care costs.

The ACA also took measures to close the prescription drug coverage gap, also known as the Medicare Part D donut hole.

Previously, when seniors exceeded a certain amount in their annual prescription drug costs, they were forced to pay all the costs of their prescriptions in this gap.

The ACA phased out the coverage gap by requiring Part D plans to pay a gradually larger share of total drug costs. It also forced drug manufacturers to give discounts on the drugs in the gap.

Inflation Reduction Act Expected To Lower Drug Costs for Medicare Beneficiaries

On August 16, 2022, President Biden signed into law the Inflation Reduction Act of 2022, a far-reaching piece of legislation that addresses climate change, taxes and healthcare. Included in the bill are provisions designed to lower prescription drug costs for people with Medicare.

There are two main policies featured in the Inflation Reduction Act that influence prescription drug prices. The first requires the federal government to negotiate with drug companies to get lower prices on some high-cost drugs covered under Medicare Part D and Part B. The list of drugs that can be negotiated starts small with just 10 Part D medications in 2026, and will expand in subsequent years to include more Part D and Part B drugs.

The second provision is designed to discourage drug companies from rapidly raising their prices. Under the Inflation Reduction Act, pharmaceutical manufacturers must pay rebates to Medicare if they increase prices faster than inflation for drugs used by Medicare beneficiaries. This inflation rebate requirement will take effect in 2023 and will use 2021 prices as a benchmark for determining price changes relative to inflation.

In addition to these provisions, the Inflation Reduction Act also includes policies capping out-of-pocket spending for Medicare Part D beneficiaries, limiting annual increases in Part D premiums for 2024 to 2030, and lowering cost sharing for insulin to $35 per month for people with Medicare.
