Question
Why did I receive another letter about my Medicare Part B premium for this year?
Answer
You received another letter about your Medicare Part B premium for this year because the amount of your Medicare Part B premium for this year changed. Although Social Security usually uses two-year-old Internal Revenue Service (IRS) modified adjusted gross income (MAGI) data to decide if you must pay an income-related adjustment, sometimes we must use three-year-old data. Other times we may base our decision on tax information you have provided. Each fall, when we ask IRS for information to determine the next year's Part B premium, we ask IRS for tax information to verify beneficiary reports. We also ask for two-year-old IRS MAGI if we have temporarily used three-year-old MAGI. When we find a difference between IRS information and information previously used and it results in a change in your Part B premium, we notify you of the change.
