What Is Part B (Medical Insurance)?
Part B helps cover medically-necessary services like doctors’ services, outpatient care, home health services, and other medical services. Part B also covers some preventive services. You can find out if you have Part B by looking at your Medicare card.
How Much Does It Cost?
You pay the Part B premium each month. Most people will pay the standard premium amount. However, if your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount, you may pay more.
Your modified adjusted gross income is your adjusted gross income plus your tax exempt interest income. Social Security will notify you if you have to pay more than the standard premium. If you have to pay a higher amount for your Part B premium and you disagree (even if you get RRB benefits), call Social Security at 1-800-772-1213. TTY users should call 1-800-325-0778 to find out if your Part B premium will be higher based on your income.
If you don’t sign up for Part B when you are first eligible, you may have to pay a late enrollment penalty.
If you have limited income and resources, see page 83 for information about help paying your Medicare premiums.
See page 121 for other Part B costs.
How You Get Part B
If you get benefits from Social Security or the Railroad Retirement Board (RRB), in most cases, you will automatically get Part B starting the first day of the month you turn age 65. If your birthday is on the first day of the month, your Part B will start the first day of the prior month. If you are under age 65 and disabled, you will automatically get Part B after you get disability benefits from Social Security or certain disability benefits from the RRB for 24 months. You will get your Medicare card in the mail about 3 months before your 65th birthday or your 25th month of disability. If you don’t want Part B, follow the instructions that come with the card, and send the card back. If you keep the card, you keep Part B and will pay Part B premiums.
