Some people get Part B automatically when they turn 65, and some must sign up for it. Learn how and when you can sign up for Part B.

For Part B, you pay:

• A premium each month.
  • If you get Social Security or a Railroad check, this premium will be taken out of this automatically. If you don’t get these, you’ll get a bill.
• A Part B deductible.
• After you meet your deductible, 20% coinsurance for most care with Original Medicare.
