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

Medicare began as a program under President Lyndon B. Johnson's administration. Johnson signed the Social Security Act Amendment into law on July 30, 1965, creating both Medicare and Medicaid. The program went into effect on July 1, 1966, giving people age 65 and older access to hospital insurance and medical insurance for the first time through a federal program.

The push for Medicare had been building for years before Johnson took office. President Harry Truman had proposed a national health insurance program in 1945, but it did not pass Congress. For the next two decades, various versions of health coverage for seniors were debated. When Johnson won the 1964 election with a large majority, he had the political support needed to move Medicare forward.

Key Takeaways

  • President Lyndon B. Johnson signed Medicare into law on July 30, 1965, and the program started on July 1, 1966.
  • Medicare was created as part of Johnson's "Great Society" agenda and was an expansion of Social Security, not a separate new program.
  • The original Medicare program covered hospital care (Part A) and medical services (Part B) for people age 65 and older.
  • Medicaid, a separate program for low-income individuals and families, was created at the same time as Medicare under the same law.

Why Medicare was created in the 1960s

Before 1966, most seniors had no health insurance. Medical bills were a leading cause of bankruptcy for older Americans. Many had retired on fixed incomes and could not afford private insurance premiums, which were expensive and often refused to cover people over 65.

Congress and the Johnson administration saw Medicare as a way to address poverty and illness among seniors. The program was built on the Social Security system that already existed, using payroll taxes to fund it. This made it politically feasible because it followed a model Americans already understood.

What the original Medicare program included

When Medicare started in 1966, it had two parts. Part A covered hospital stays, skilled nursing facility care, and some home health services. Part B covered doctor visits, outpatient care, and other medical services. People age 65 and older were automatically enrolled in Part A if they had paid into Social Security for at least 10 years.

Part B was optional and required a monthly premium. Beneficiaries had to sign up during a specific enrollment period. The program did not cover prescription drugs, dental care, vision care, or hearing aids — gaps that remain in traditional Medicare today.

How Medicare has changed since 1966

Medicare has expanded several times since Johnson signed it into law. In 1972, Congress extended Medicare to people under 65 who had been receiving Social Security disability benefits for two years, and to people with end-stage renal disease. In 1983, the program changed how it paid hospitals, moving from paying for each service to paying a fixed amount per diagnosis.

The biggest change came in 2006 when Part D (prescription drug coverage) was added. This gave beneficiaries the option to purchase drug coverage through private insurance plans. Part C (Medicare Advantage) had been introduced in 1997 as an alternative way to receive Medicare benefits through private insurance companies instead of traditional Medicare.

In 2020, Congress added telehealth services to Medicare, which expanded during the COVID-19 pandemic. The program continues to change as Congress passes new laws and as the Centers for Medicare and Medicaid Services (CMS) updates rules and coverage.

Who was may be able to access when Medicare started

The original law made Medicare available to people age 65 and older. This age was chosen because it matched the age for full Social Security retirement benefits at the time. Spouses of may be able to access beneficiaries could also enroll, as could widows and widowers age 60 and older.

People who had not paid into Social Security could still enroll in Part B by paying a higher premium. Over time, may be able to access expanded to include younger people with disabilities and people with certain conditions like end-stage renal disease or ALS (amyotrophic lateral sclerosis).

The political debate around Medicare's creation

Medicare was controversial when it was proposed. Some members of Congress and business groups opposed it, arguing that the federal government should not run a health insurance program. The American Medical Association initially opposed Medicare, concerned it would interfere with the doctor-patient relationship.

Despite the opposition, the law passed with strong support from Democrats and some Republicans. Johnson framed it as a natural extension of Social Security and as a way to reduce poverty among seniors. He signed the bill at the Harry S. Truman Library in Independence, Missouri, as a tribute to Truman's earlier efforts to create national health insurance.

How Medicare funding works

Medicare is funded through a combination of payroll taxes, premiums, and general federal revenue. Workers and employers each pay a Medicare tax of 1.45% on wages (2.9% combined). Self-employed people pay the full 2.9%. These taxes go into the Hospital Insurance Trust Fund, which pays for Part A.

Part B and Part D are funded partly by beneficiary premiums and partly by general federal tax revenue. The amount of the premium depends on income for some beneficiaries. People with higher incomes pay higher premiums for Part B and Part D.

Frequently Asked Questions

Did any president before Johnson try to create Medicare?

Yes. President Harry Truman proposed a national health insurance program in 1945, but Congress did not pass it. The idea was debated for the next 20 years. President John F. Kennedy also supported Medicare legislation, but it did not pass during his administration. Johnson succeeded where they had not.

Was Medicare the first federal health insurance program in the United States?

No. The Veterans Health Administration, created after World War I, provided health care to veterans. Medicare was the first large federal health insurance program for a civilian population based on age rather than military service or employment.

How many people enrolled in Medicare when it started?

Approximately 19 million people enrolled in Medicare during its first year. This represented most of the population age 65 and older at that time. Enrollment has grown as the population has aged and as may be able to access has expanded to younger people with disabilities.

Can you opt out of Medicare if you are 65 or older?

You can delay enrolling in Part B if you have other health insurance through an employer, but Part A enrollment is automatic for most people age 65 and older who have paid into Social Security. Delaying Part B can result in higher premiums later, so it is important to understand your options before your 65th birthday.

Has Medicare coverage changed since 1966?

Yes, significantly. The program now covers prescription drugs (Part D), offers private insurance alternatives (Part C), and includes preventive services like screenings and vaccinations. Congress has also added coverage for telehealth visits and other services. However, gaps remain — dental, vision, and hearing care are still not covered by traditional Medicare.
