Medicare Basics: The Four Parts Explained

Medicare isn't one thing; it's a set of parts you assemble. Understand the four building blocks and the rest of your decisions get much simpler.

The two ways to get Medicare

Everyone starts with Original Medicare — Part A (hospital) and Part B (medical). From there you choose one of two paths.

Path one keeps Original Medicare and adds a Medicare Supplement (Medigap) to cover the gaps, plus a standalone Part D drug plan. Path two replaces the delivery of your benefits with a Medicare Advantage plan (Part C) from a private insurer, which usually bundles drug coverage and extras.

What each part covers

Here's the shorthand most people find easiest to remember:

  • Part A: inpatient hospital stays, skilled nursing, hospice, some home health. Most people pay no premium because they paid in through payroll taxes.
  • Part B: doctor visits, outpatient care, preventive services, durable medical equipment. It carries a standard monthly premium set each year.
  • Part C (Medicare Advantage): a private plan that provides your Part A and B benefits, usually with Part D and extras like dental or vision built in.
  • Part D: prescription drugs, offered through standalone plans or built into most Advantage plans.

Who's eligible

Medicare is a federal program run by the Centers for Medicare & Medicaid Services (CMS) — not the same as Medicaid, which is a state program based on income. You generally qualify if you're:

  • Age 65+ — a U.S. citizen or a permanent resident who has lived here at least 5 continuous years.
  • Under 65 with a disability — after receiving Social Security Disability Insurance (SSDI) for 24 months.
  • Diagnosed with End-Stage Renal Disease (ESRD) — kidney failure requiring dialysis or a transplant.
  • Diagnosed with ALS (Lou Gehrig's disease) — eligible immediately upon SSDI approval.

Original Medicare vs. Medicare Advantage at a glance

The two paths differ most in provider choice, cost structure, and extras:

Drug coverageAdd a separate Part D planUsually included
Extra benefitsNone (add Medigap for gaps)Dental, vision, hearing, fitness
Out-of-pocket maxNone unless you add MedigapAnnual cap required by law

What Medicare doesn't cover

Original Medicare leaves some notable gaps. It generally does not cover:

  • Most dental, vision, and hearing care
  • Long-term (custodial) nursing-home care
  • Cosmetic surgery
  • Most care outside the United States
  • Routine foot care and acupuncture (with limited exceptions)

FAQ

Common questions

What's the difference between Medicare and Medicaid?

Medicare is a federal program based on age or disability. Medicaid is a state program based on income. Some people qualify for both — called "dual eligible" — and can receive extra benefits through special plans.

Do I need Part B if I'm still working?

If you have creditable coverage through a large employer, you may be able to delay Part B without penalty. If your employer has fewer than 20 employees, or you're on COBRA or retiree coverage, the rules differ — this is exactly the kind of timing mistake we help you avoid.

Is Medicare free?

Part A is usually premium-free if you or your spouse paid Medicare taxes for 10+ years. Part B and Part D have monthly premiums, and Advantage or Supplement plans have their own costs. We'll show you the full picture for your situation.

Can I have Medicare and employer insurance at the same time?

Yes. If you're still working at 65 with employer coverage, your employer plan may be primary. When you retire, you enroll in Medicare during a Special Enrollment Period to avoid penalties.

Are you connected to Medicare or the government?

No. Mere Benefits is a private, independent agency and is not connected with or endorsed by the U.S. government or the federal Medicare program. We don't offer every plan available in your area — to review all your options, contact Medicare.gov or 1-800-MEDICARE.

How much does it cost to work with Mere Benefits?

Nothing extra. Plan prices are set by the carriers and are identical whether you enroll on your own or with a licensed agent — we're paid by the carriers, so our guidance is free to you.

How do I get started?

Call or text (904) 654-5450, email info@merebenefits.com, or use our contact form. We'll set up a relaxed, no-pressure conversation — in person on the First Coast, or by phone and video.

Are you independent, or tied to one insurance company?

Independent. We aren't captive to a single insurer, so we compare the options across the carriers we represent and recommend what fits you — not what pays us most.

Will I have to change doctors?

Not if we can help it. Before recommending a plan we confirm your doctors are in-network and your prescriptions are covered, so keeping your care is part of the decision.

Can you help by phone and video, or only in person?

Both. We meet clients in person across Northeast Florida and Camden County, GA, and serve all 11 of our licensed states by phone and video.
