The ABCDs of Medicare

Original Medicare

Original Medicare is administered by the federal government. Once you decide to join Medicare, you have a few different options. The federal government refers to these Medicare benefits and options as Parts A, B, C and D. No matter which option you choose, the first step is the same: Enroll in Original Medicare, also known as Parts A and B.

Part A

Hospital insurance inpatient care

  • Hospital room
  • Inpatient acute care
  • Inpatient mental health care
  • Skilled nursing facility care
  • Home health services
  • Inpatient tests and services
  • Other

Part B

Medical insurance outpatient care

  • Doctor visits (including annual wellness visit)
  • Outpatient services
  • Clinical lab services
  • Some preventive care
  • Durable medical equipment, such as oxygen and wheelchairs
  • Diagnostic tests such as X-rays and MRIs
  • Other

Original Medicare doesn't cover everything. Many Medicare recipients choose to buy additional plans from private insurance companies such as Prevea360 Medicare Advantage for alternative coverage options and to spend less out-of-pocket.

Part C

Medicare Advantage

  • Replaces Original Medicare Parts A and B
  • Has an annual maximum out-of-pocket
  • Often includes Part D coverage (prescription drugs)
  • Often includes extra benefits like dental, eyewear and more

Part D

Prescription drug coverage

  • Covers outpatient prescription medications
  • Offered in MAPD Plans (Medicare Advantage with Part D), or can be purchased separately in addition to Original Medicare
