Breaking Down the Parts of Medicare

A simple breakdown of A, B, C, and D—without the alphabet soup.
“Clarity is the beginning of confidence.” — Robin Sharma


Navigating Medicare can feel like learning a foreign language. With terms like Part A, Part B, Part C, and Part D thrown around, it’s easy to feel lost before you even get started. But once you understand what each part covers, choosing the right path becomes much clearer—and far less intimidating.

Let’s break it down in plain English.


Part A: Hospital Insurance

Think of Part A as your Medicare hospital coverage. It helps pay for:

  • Inpatient hospital stays

  • Skilled nursing facility care (after a qualifying hospital stay)

  • Hospice care

  • Limited home health services

Cost:
Most people pay $0 per month for Part A if they (or their spouse) worked at least 10 years. In 2025, the hospital deductible is $1,632 per benefit period.

When you need it:
If you’re ever admitted to the hospital or a skilled nursing facility, Part A is your safety net.


Part B: Medical Insurance

Part B covers the day-to-day health care most of us use more frequently, including:

  • Doctor visits

  • Preventive services (like screenings and vaccines)

  • Lab work

  • Durable medical equipment

  • Outpatient services

Cost:
The standard monthly premium in 2025 is $174.70, but higher-income earners may pay more due to IRMAA (Income-Related Monthly Adjustment Amount).

There’s also a deductible of $240 per year and typically 20% coinsurance for covered services.


Part C: Medicare Advantage (MAPD)

Part C, also known as Medicare Advantage, is offered by private insurance companies approved by Medicare. These plans bundle Parts A and B—and often Part D—into one plan.

Bonus Benefits Often Included:

  • Prescription drug coverage

  • Dental, vision, and hearing care

  • Gym memberships and wellness programs

  • Over-the-counter benefits

  • Transportation assistance

Cost:
Some plans have $0 monthly premiums, though you still pay your Part B premium. You may also have copays and deductibles depending on the plan.

Watch Out:
You’ll typically have to use a network of doctors, and referrals may be required for specialists.


Part D: Prescription Drug Coverage

Part D is optional prescription drug coverage available through private insurers. It helps pay for:

  • Generic and brand-name medications

  • Vaccines not covered by Part B

  • Medications filled at pharmacies or via mail order

Cost:
Monthly premiums vary by plan and income level. Be sure to choose a plan that covers the medications you take regularly.

Penalty Alert:
If you don’t enroll in Part D when you’re first eligible and don’t have other credible drug coverage, you may face a lifetime late enrollment penalty.

Which Path Should You Take?

  • Original Medicare (Parts A & B): Great if you want provider freedom and plan to add Medigap for cost protection.

  • Medicare Advantage (Part C): A good choice if you want an all-in-one plan with extra perks—but make sure your doctors are in-network.

  • Part D: Crucial for anyone needing prescription coverage.
