The Continuing Disability Review Notice Arrives in Your Mailbox

Three months before your birthday, the Social Security Administration mails you a Continuing Disability Review (CDR) notice. This is not a warning that your benefits will stop. It is a form asking you to report changes in your medical condition, work activity, and living situation since your last review. Social Security uses your answers to decide whether you still meet the medical requirements for SSDI.

The notice arrives in a white envelope from the Social Security Administration. It includes a form called SSA-455-BK (the Continuing Disability Review form) and a cover letter explaining what you need to do and by what date. The important date is usually 10 days from the date on the letter, though you can request an extension if you need more time.

Not everyone receives a CDR notice three months before their birthday. Social Security sends them based on a schedule that depends on your diagnosis, your age, and how long you have been on SSDI. Some people receive them every three years; others every five or seven years. If you have a condition that is unlikely to improve—such as total blindness or loss of both legs—you may go many years without receiving one.

Key Takeaways

  • The Continuing Disability Review form asks about changes in your health, work, and household since your last review, and you must return it by the important date on the letter.
  • Returning the form on time does not mean your benefits will stop; it means Social Security has the information it needs to make a decision.
  • If you do not return the form by the important date, Social Security will stop your benefits until you do, even if you are still disabled.
  • You can request a 10-day extension by phone, mail, or in person at your local Social Security office before the important date passes.
  • Changes in your medical condition, work income, or living arrangement may affect your benefits, but reporting them honestly is required by law.

What Information the Form Asks For

The SSA-455-BK form has three main sections. The first asks about your current medical condition: whether your symptoms have improved, worsened, or stayed the same; what doctors you are seeing; and whether you have had any surgeries, hospitalizations, or new treatments since your last review.

The second section asks about work. It asks whether you have worked for pay, how much you earned, and whether you received any other income such as rental payments, interest, or gifts. This section is important because earning above the Substantial Gainful Activity (SGA) level—which is $1,550 per month in 2024, though this amount changes yearly—can trigger a medical review or affect your benefits.

The third section asks about your living situation: whether you still live at the same address, whether anyone else in your household has changed, and whether you receive help paying for food or housing. These questions help Social Security understand whether your circumstances have shifted in ways that might affect your need for benefits.

What Happens If You Do Not Return the Form

If you do not return the completed form by the important date, Social Security will send you a notice saying your benefits will stop. The stop date is usually one month after the important date. You can still prevent the stop by returning the form before that date, but if benefits do stop, you cannot receive back pay for the months you missed.

Once your benefits stop, you must return the form to have them restarted. Social Security will not restart them automatically. You will need to contact your local Social Security office or call 1-800-772-1213 to submit the form and ask for reinstatement. The process can take several weeks, and you will not receive payment for the gap period.

If you are unable to return the form because of a medical or other emergency, you can explain this in writing and ask Social Security to waive the important date. Send a letter to your local Social Security office explaining why you could not meet the important date. Include your Social Security number and the date of the CDR notice.

How to Complete and Return the Form

Read the entire form before you start writing. The instructions are on the first page. Answer every question honestly and completely. If a question does not explore to you, write "N/A" rather than leaving it blank. Incomplete forms are often returned, which delays the review.

You can return the form by mail, in person at your local Social Security office, or online through your my Social Security account if you have created one. Mailing is the slowest option; allow at least two weeks for the form to arrive. In-person submission is fastest because you receive a receipt showing the date Social Security received it. Online submission through my Social Security is when ready and creates a record you can access later.

Keep a copy of the completed form for your records before you send it. If Social Security later claims they did not receive it, you will have proof of what you submitted and when.

Medical Evidence and What to Gather Before Responding

Before you fill out the form, gather recent medical records from your doctors. You do not have to attach them to the form, but having them nearby helps you answer questions accurately about your treatment, medications, and symptoms. Write down the names and phone numbers of all doctors you have seen in the past year.

If your condition has improved, be honest about it. Improvement does not automatically mean you lose benefits. Social Security looks at whether you can work at the SGA level despite the improvement. If you still cannot work full-time because of your condition, your benefits may continue even if you are somewhat better than before.

If your condition has worsened or you have developed new medical problems, describe them in detail. Use the space provided on the form, or attach a separate letter if you need more room. Include the date the new problem started, what doctors you have seen, and what treatment you are receiving.

Work and Income Reporting on the CDR Form

Report all work income honestly, including self-employment income, gig work, and informal jobs. Social Security cross-checks your report against tax records and wage reports from employers, so underreporting will be discovered. If you have worked and earned above the SGA level, your benefits may be affected, but hiding the work will result in an overpayment that you will have to repay.

If you have earned below the SGA level, report it. Social Security has a Trial Work Period (TWP) that allows you to test your ability to work without losing benefits. During the TWP, you can earn any amount and keep your full SSDI payment. After the TWP ends, you enter the Extended may be able to access Period (EEP), during which you can earn up to the SGA level and still receive benefits in months you do not earn above that threshold.

If you are unsure whether your work income will affect your benefits, call Social Security before you return the form. They can explain how your specific earnings will be treated and help you understand what to report.

What Happens After You Return the Form

After Social Security receives your completed form, a disability examiner will review it along with your medical records. If the examiner believes you still meet the medical requirements for SSDI, they will send you a letter saying your benefits will continue. This letter usually arrives within two to three months.

If the examiner has questions about your medical condition or work activity, they may ask you to have a new medical examination or provide additional records from your doctors. They will send you a letter explaining what they need and by what date. Respond to these requests promptly, as failure to do so can result in a benefits stop.

If the examiner decides you no longer meet the medical requirements for SSDI, they will send you a notice of decision explaining why and telling you that your benefits will stop. You have the right to request reconsideration within 10 days of receiving the notice. If you disagree with the reconsideration decision, you can request a hearing before an administrative law judge.

Frequently Asked Questions

Can I lose my benefits just because I returned the CDR form?

No. Returning the form does not cause you to lose benefits. Social Security uses the information to decide whether you still meet the medical requirements. If you still cannot work because of your condition, your benefits will continue. Losing benefits happens only if the examiner concludes you no longer meet the medical definition of disability.

What if I moved and did not get the CDR notice?

Contact Social Security when ready. Call 1-800-772-1213 or visit your local office. Tell them you did not receive the notice and ask them to send you a new one. If the important date has already passed, explain that you did not receive the original notice and ask them to extend the important date or waive it. Bring proof of your current address, such as a utility bill or lease.

Do I have to report my spouse's income or my parents' income on the CDR form?

No. SSDI is based on your own work record and your own medical condition. Your spouse's or parents' income does not affect your SSDI benefits. Report only your own income and changes in your own medical condition.

What if I am working and earning above the SGA level?

Report your earnings honestly on the CDR form. Earning above the SGA level does not automatically stop your benefits, but it triggers a medical review. If you are earning above SGA and Social Security determines you can do substantial work, your benefits may stop. However, you may be may have access to to a work incentive such as the Plan to Achieve Self-Support (PASS) that allows you to set aside income for a work goal.

Can I request an extension of the CDR important date?

Yes. You can request a 10-day extension by calling Social Security, visiting your local office, or mailing a written request to the address on the notice. Request the extension before the original important date passes. If you have a good reason for needing more time—such as a hospitalization or difficulty obtaining medical records—Social Security will usually grant the extension.
