Medicare Part B – Medical Insurance

Medicare Part B is the portion of Medicare that covers outpatient and medical services. It’s often called “medical insurance” because it pays for doctor visits, preventive care, and treatments outside of hospital stays.


  • Primary care and specialists.
  • Office visits, consultations, and follow-ups.
  • Services received without being admitted to a hospital.
  • Includes surgeries, diagnostic tests, and lab work.
  • Screenings (cancer, diabetes, heart disease).
  • Vaccinations (flu, pneumonia, COVID-19).
  • Annual wellness visits.
  • Wheelchairs, walkers, oxygen equipment, and other medically necessary supplies.
  • Limited coverage for skilled nursing, physical therapy, or speech therapy at home.

  • Standard monthly premium ($202.90 in 2026).
  • Higher-income beneficiaries may pay more (Income-Related Monthly Adjustment Amount, IRMAA).
  • Annual deductible ($283 in 2026).
  • Typically 20% of the Medicare-approved amount for most services after the deductible is met.

Example:
If a doctor visit costs $100, Medicare pays $80 and you pay $20.


  • Most people enroll in Part B during their Initial Enrollment Period (IEP). You can delay enrollment if you have qualifying employer-sponsored coverage.
  • Late Enrollment Penalty: Your premium increases by 10% for each 12-month period you were eligible but did not enroll—and you pay that penalty for life.

  • Provides coverage for everyday medical needs that Part A doesn’t cover.
  • Ensures access to preventive care, helping detect and manage conditions early.
  • Complements Part A to form the foundation of Original Medicare.

Medicare Part B is your medical insurance, covering doctor visits, outpatient care, preventive services, durable medical equipment, and more. It requires a monthly premium and cost-sharing, but it’s essential for comprehensive coverage alongside Part A.
