What Are the Different Parts of Medicare? 

Medicare is a federal health insurance programme primarily for individuals aged 65 and older, but it also covers some younger people with disabilities. It is divided into four key parts: 

  • Part A (Hospital Insurance) 
  • Part B (Medical Insurance) 
  • Part C (Medicare Advantage Plans) 
  • Part D (Prescription Drug Plans) 

Each part covers different services, costs, and benefits. Understanding these distinctions is crucial when choosing the best plan for your needs. 

Medicare Parts A, B, C, D Explained 

Medicare Part A: Hospital Insurance 

Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health care. Most people qualify for Part A without paying a premium if they or their spouse paid Medicare taxes while working. 

Key Points: 

  • Covers hospitalization, including semi-private rooms and meals 
  • Includes skilled nursing care after a hospital stay 
  • No monthly premium for most beneficiaries 
  • Deductibles and coinsurance apply 

Medicare Part B: Medical Insurance 

Part B helps cover medically necessary services like doctor visits, outpatient care, preventive services, and some home health care. Part B usually requires a monthly premium based on income. 

Key Points: 

  • Covers doctor visits, outpatient care, and preventive services 
  • Requires a monthly premium 
  • Deductibles and 20% coinsurance usually apply 

Medicare Part C: Medicare Advantage 

Part C, or Medicare Advantage, is an alternative to Original Medicare (Parts A and B). Offered by private insurers approved by Medicare, these plans combine Parts A and B and often include additional benefits like vision, dental, and prescription drugs. 

Benefits: 

  • Combines hospital and medical coverage 
  • Often includes prescription drug coverage (Part D) 
  • May offer extra benefits like wellness programs 
  • Requires use of plan networks

  • Has monthly premiums, deductibles, and copayments 
  • Formularies determine which drugs are covered
