    What Is Medicare?

    Medicare — also called Medicare

    Medicare is the federal health insurance program primarily for people age 65 and older, as well as certain younger people with disabilities or specific medical conditions. Medicare helps pay for hospital care, medical services, prescription drugs, and other healthcare, but it does not cover every medical expense.

    What is Medicare?

    Medicare is a federal health insurance program administered by the Centers for Medicare & Medicaid Services (CMS).

    Most people become eligible for Medicare when they turn 65, but younger individuals may also qualify if they receive Social Security Disability Insurance (SSDI) for the required waiting period or have certain qualifying medical conditions, such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).

    Medicare is not based on income. Eligibility is generally based on age, disability status, or specific medical conditions.

    How Medicare works

    Medicare is divided into different parts, each covering different healthcare services.

    Part A (Hospital Insurance) helps cover:

    Hospital stays

    Skilled nursing facility care

    Hospice care

    Some home health services

    Part B (Medical Insurance) helps cover:

    Doctor visits

    Outpatient care

    Preventive services

    Medical equipment

    Laboratory services

    Part C (Medicare Advantage) is offered by private insurance companies approved by Medicare and combines Part A and Part B coverage. Many plans also include prescription drug coverage and additional benefits.

    Part D (Prescription Drug Coverage) helps pay for covered prescription medications through private plans approved by Medicare.

    Who qualifies for Medicare?

    You may qualify for Medicare if you:

    Are 65 or older.

    Have received SSDI benefits for the required waiting period.

    Have End-Stage Renal Disease (ESRD).

    Have Amyotrophic Lateral Sclerosis (ALS).

    Some people qualify automatically, while others must enroll during an eligible enrollment period.

    What does Medicare cost?

    Most people do not pay a monthly premium for Part A if they or their spouse paid Medicare taxes for enough years while working.

    However, beneficiaries may pay:

    Monthly Part B premiums.

    Deductibles.

    Coinsurance.

    Copayments.

    Part D premiums, depending on the plan selected.

    Costs vary based on income, coverage choices, and the services received.

    Medicare vs. Medicaid

    Medicare and Medicaid are often confused because both help people pay for healthcare.

    Medicare

    Federal health insurance program.

    Primarily based on age or disability.

    Not based on financial need.

    Available nationwide under federal rules.

    Medicaid

    Joint federal-state health coverage program.

    Based primarily on income and other eligibility requirements.

    Administered by each state.

    Eligibility and covered services vary by state.

    Some people qualify for both Medicare and Medicaid. These individuals are often referred to as dual eligible beneficiaries.

    Why this matters

    Health insurance becomes increasingly important as people age or develop serious medical conditions. Understanding Medicare can help you avoid enrollment penalties, choose the right coverage, and coordinate benefits with programs such as SSDI, TRICARE, VA health care, or Medicaid.

    In real life

    • A 65-year-old enrolls in Medicare Part A and Part B after retiring from full-time work.
    • An individual receiving SSDI becomes eligible for Medicare after completing the required waiting period.
    • A military retiree uses Medicare together with TRICARE For Life to help reduce out-of-pocket healthcare costs.
