What Is Medicare and What Does It Mean?

Medicare is a federal health insurance program primarily designed for people aged 65 and older. It also covers certain younger individuals with disabilities and those with End-Stage Renal Disease (permanent kidney failure requiring dialysis or transplant). The program helps cover hospital stays, doctor visits, prescription drugs, and other healthcare services.

The term Medicare refers to this government-run insurance program, which aims to reduce the financial burden of medical care for eligible individuals. It is not a health care provider itself but a way to pay for health care services.

Key Parts of Medicare

Medicare is divided into several parts, each covering different types of care:

• Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care.

• Part B (Medical Insurance): Covers doctor visits, outpatient care, preventive services, and some home health care.

• Part C (Medicare Advantage): An alternative to Original Medicare (Parts A and B), offered by private companies approved by Medicare. These plans often include additional benefits like vision, dental, and prescription drugs.

• Part D (Prescription Drug Coverage): Helps cover the cost of prescription medications.

  
  

Understanding these parts helps beneficiaries choose the coverage that best fits their needs.

Is Medicare Public or Private?

Medicare is primarily a public program funded and administered by the federal government. It is part of the Social Security Act and managed by the Centers for Medicare & Medicaid Services (CMS). This means Medicare is a government-run program designed to provide health insurance to eligible Americans.

However, some aspects of Medicare involve private companies:

• Medicare Advantage (Part C) plans are offered by private insurance companies approved by Medicare.

• Prescription drug plans (Part D) are also provided through private insurers.

  
  

In summary, Medicare itself is a public program, but it works with private insurers to deliver certain types of coverage.

How Is Medicare Funded?

Medicare is funded mainly through federal sources, not state governments. Its funding comes from several streams:

• Payroll Taxes: Workers and employers each pay 1.45% of wages toward Medicare through the Federal Insurance Contributions Act (FICA). Self-employed individuals pay 2.9%.

• Premiums: Beneficiaries pay monthly premiums for Part B and Part D coverage. Some higher-income individuals pay higher premiums.

• General Federal Revenues: The government contributes funds from general tax revenues to cover costs not paid by payroll taxes or premiums.

• Trust Funds: Medicare has two trust funds — the Hospital Insurance Trust Fund (for Part A) and the Supplementary Medical Insurance Trust Fund (for Parts B and D).

  
  

Because Medicare is federally funded, it operates uniformly across all states, unlike Medicaid, which is jointly funded by states and the federal government.

How Do You Use Medicare?

Once enrolled, Medicare beneficiaries can use their coverage to pay for eligible healthcare services. Here’s how it typically works:

• Original Medicare (Parts A and B): You can visit any doctor or hospital that accepts Medicare. You pay deductibles and coinsurance, and Medicare covers the rest.

• Medicare Advantage (Part C): You usually need to use a network of providers. These plans often have lower out-of-pocket costs but may require referrals.

• Prescription Drug Plans (Part D): You get your medications at pharmacies that accept your plan.

  
  

Medicare does not cover all healthcare costs. For example, it generally does not cover long-term care, most dental care, or routine vision and hearing exams. Many beneficiaries purchase supplemental insurance (Medigap) to help cover these gaps.

How to Enroll in Medicare in the US

Enrolling in Medicare is a straightforward process, but timing is important to avoid penalties or gaps in coverage.

When to Enroll

• Initial Enrollment Period (IEP): This 7-month window starts three months before you turn 65, includes your birthday month, and ends three months after.

• General Enrollment Period: If you miss your IEP, you can enroll between January 1 and March 31 each year, with coverage starting July 1.

• Special Enrollment Periods: Available if you delayed enrollment due to other coverage, such as employer insurance.

  
  

How to Enroll

• Online: Visit the Social Security Administration website to apply.

• By Phone: Call the Social Security office.

• In Person: Visit a local Social Security office.

  
  

You will need to provide personal information such as your Social Security number and proof of age or disability.

Enrollment Tips

• If you are already receiving Social Security benefits, you may be automatically enrolled.

• Review your options carefully, especially if considering Medicare Advantage or Part D plans.

• Keep track of deadlines to avoid late enrollment penalties.

  
  

Is Medicare State Funded or Federally Funded?

Medicare is federally funded and administered. Unlike Medicaid, which is a joint federal and state program, Medicare’s funding and rules are consistent across all states. This federal funding ensures that Medicare benefits are the same regardless of where you live in the United States.

States do not contribute to Medicare funding, but they may assist with outreach and enrollment services. Some states also offer programs to help low-income Medicare beneficiaries with premiums and out-of-pocket costs.

In summary, Medicare is an important part of the American healthcare system, providing coverage or millions of eligible individuals. Medicare ensures access to necessary medical services, helping beneficiaries maintain their health and mobility.
