Introduction

Healthcare is one of the most important concerns for Americans as they age. Medical costs can quickly become overwhelming without proper coverage. That is where Medicare plays a crucial role. Medicare is a federal health insurance program in the United States designed primarily for individuals aged 65 and older, as well as certain younger people with disabilities and individuals with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).

If you are approaching retirement, helping a parent enroll, or researching health insurance options in the U.S., this comprehensive guide will explain everything you need to know about Medicare coverage, eligibility, costs, enrollment periods, and plan options.

What Is Medicare?

Medicare is a federal health insurance program administered by the U.S. government. It was established in 1965 to ensure seniors have access to affordable healthcare coverage.

Unlike Medicaid, which is income-based, Medicare eligibility is primarily age-based or disability-based.

Who Qualifies for Medicare?

You may qualify for Medicare if:

• You are 65 years or older
• You are under 65 with a qualifying disability
• You have End-Stage Renal Disease (permanent kidney failure requiring dialysis or transplant)
• You have ALS (Lou Gehrig’s disease)

Many people automatically get enrolled in Medicare if they are already receiving Social Security benefits before turning 65.

The History of Medicare in the United States

Medicare was signed into law on July 30, 1965, by President Lyndon B. Johnson as an amendment to the Social Security Act.

Key milestones include:

• 1965: Medicare established
• 1972: Expanded to include people under 65 with disabilities
• 2003: Medicare Part D (prescription drug coverage) added

Today, Medicare covers over 65 million Americans.
