If you want to appeal your Medicare Part B income-related monthly adjustment amount to an
administrative law judge (ALJ), you will need to complete an IRS form 8821 so we can
redisclose your tax information to an ALJ in the Department of Health and Human Services’
Office of Medicare Hearings and Appeals.
The IRS form 8821 is not a request for a hearing. You need to complete a form HA-501-U5,
“Request for a Hearing by an Administrative Law Judge.” You can find the HA-501-U5 online at
http:www.ssa.gov/online/ha-501.pdf, or you can call 1-800-772-1213 (TTY-1-800-325-0778) to
request the form.
Send signed originals of both the HA-501-U5 and the IRS form 8821 to: Social Security
Administration, Southeastern Program Service Center. P.O. Box 12247, Birmingham, AL
35202. If you have any questions, call us at 1-800-772-1213 (TTY-1-800-325-0778).
If you need to use an IRS form 8821 for any other purpose, do not use this guidance.
If items on the IRS form 8821 are missing or incomplete, we will not be able to process your
request, and your request for a hearing may be dismissed.

Follow the IRS Form 8821 instructions and note the following:
Line 1: Taxpayer Information
• You do not need to provide an Employer Identification Number or a Plan Number.
Line 2: Appointee
• Please enter the following: Office of Medicare Hearings and Appeals.

income-related premium adjustment (YYYY format). This information is in the letter SSA sent
you explaining your Medicare Part B income-related premium.
