How You Qualify
If you’re 65 years old, or over 65 and you or your spouse paid Medicare taxes for at least 10 years, you’re eligible for Medicare and can get Medicare Part A for free. While most people will not pay a premium for Part A, there is a monthly cost for Part B. Generally, this is taken out of your Social Security, Railroad Retirement or Civil Service Retirement check. If you don’t get any of those checks, Medicare sends a monthly bill.
If you’re under 65 and getting disability benefits from Social Security for 2 years, you’ll be automatically enrolled in Medicare Parts A and B.
