Medicare eligibility depends on following factors:

  • Age: You must be 65 or older to participate in Medicare.
  • Disability:Medicare is available to under-65 disabled people who meet certain requirements.
  • End-Stage Renal Disease: You are Medicare-eligible if you have ESRD.

Part A is free for most people. However, Part B of Medicare costs money. The premium is withdrawn monthly from your Civil Service Retirement, Railroad Retirement, or Social Security check. If you don’t pay, Medicare bills you every three months.
