GUIDE: How Medicare Works

Medicare can seem overwhelming, especially if you’re enrolling for the first time. This guide aims to simplify the complex world of Medicare, from explaining the four different parts to comparing Original Medicare and Medicare Advantage.

Defining Parts A, B, C, and D of Medicare

Original Medicare (Parts A & B)

  • Part A: Hospital Insurance covering inpatient hospital stays, care in a skilled nursing facility, and hospice care.
  • Part B: Medical Insurance covering outpatient care, doctor visits, and preventive services.

Medicare Advantage (Part C)

  • Private health insurance plans contracted with the government, which often combine Parts A, B, and sometimes D.

Medicare Part D

  • Provides prescription drug coverage, either as a standalone plan or as part of a Medicare Advantage plan.

Original Medicare vs. Medicare Advantage: What’s the Difference?

Comprehensive Coverage

  • Original Medicare: Covers essential healthcare services.
  • Medicare Advantage: Often adds vision, dental, and prescription drug coverage.

Predictability of Costs

  • Original Medicare: Uses 20% coinsurance for many Part B services.
  • Medicare Advantage: Uses co-pays, offering a fixed cost for services.

Out-of-Pocket Maximum

  • Original Medicare: No out-of-pocket maximum.
  • Medicare Advantage: Fixed out-of-pocket maximum, after which the plan covers 100% of your healthcare costs.

Understanding Medicare Part D

The Donut Hole/Coverage Gap

  • This is a temporary stage where your prescription drug costs might increase after reaching a certain expenditure limit within a year.
  • Not everyone will enter the coverage gap, but if you do, you’ll have to pay more for your medications temporarily.


Understanding Medicare can be challenging but knowing the difference between Original Medicare and Medicare Advantage, as well as how Medicare Part D works, can help you make an informed decision that suits your healthcare needs. Always consult with healthcare professionals for tailored advice.
