A Function Report Describes What You Can and Cannot Do Every Day

A Function Report is a form the Social Security Administration (SSA) sends you during an SSDI process or appeal. It asks you to describe in detail how your condition affects your ability to work, care for yourself, and move around. The SSA uses your answers to decide whether your medical condition is severe enough to prevent you from working.

The form is not a medical exam. You fill it out yourself, at home, in your own words. The SSA compares what you write on the Function Report to what your doctors have written in your medical records. If the two stories match, it strengthens your case. If they contradict each other, it weakens it.

You will receive the Function Report by mail if the SSA needs more information about how your condition affects your daily life. You do not have to request it—the agency sends it when they think they need it. The form comes with a important date, usually 10 days from the date on the letter, though you can ask for more time if you need it.

Key Takeaways

  • The Function Report asks you to describe specific tasks you cannot do or struggle with because of your condition, not to diagnose yourself or list your medical history.
  • Your answers must match what your doctors have documented in your medical records, or the SSA will assume you are exaggerating or that your condition is not as limiting as you claim.
  • The form covers personal care, household chores, work-related tasks, and social activities—the SSA wants to know what a typical day looks like for you.
  • You should keep a copy of what you submit and bring it with you to any hearing, because a judge may ask you to explain your answers.

What the Function Report Actually Asks

The form has several sections, each focused on a different part of your life. The SSA wants to know what you do from the moment you wake up to the moment you go to bed, and how your condition gets in the way.

One section asks about personal care: Can you bathe yourself? Dress yourself? Prepare meals? Take medications on time? Another section covers household chores: Can you do laundry, dishes, or yard work? A third section asks about work-related tasks: Can you follow written instructions? Concentrate for long periods? Sit or stand for hours? The final section covers social activities: Do you leave the house? Interact with family or friends? Drive or use public transportation?

For each task, you describe not just whether you can do it, but how your condition makes it difficult. For example, instead of writing "I cannot walk far," you might write "I can walk to the mailbox but my legs hurt so much I have to sit down for 20 minutes before I can walk back." That level of detail is what the SSA is looking for.

Why Your Answers Must Match Your Medical Records

The SSA has your medical records from your doctors, hospitals, and any specialists you have seen. They will compare what you write on the Function Report to what those records say. If your doctor wrote that you have severe arthritis in both knees and can only walk a few blocks, but you write that you walk three miles every day, the SSA will not believe either statement.

This does not mean you have to agree with everything your doctor wrote. If your medical records are incomplete or wrong, you can correct them. But you need to explain the correction and, if possible, provide updated medical evidence. straightforward contradicting your records without explanation will hurt your case.

The SSA also looks for patterns. If you say you cannot work because of pain, but your social media shows you hiking or playing sports, the SSA will use that against you. Be honest about what you can do on your best days and what you cannot do on your worst days. The form asks about your typical day, not your best day.

How to Fill Out the Function Report Accurately

Before you sit down to write, gather your medical records and any notes from your doctors about your limitations. Read through them so you know what they have documented. Then write your answers based on your actual experience, not on what you think the SSA wants to hear.

Be specific. Instead of "I am tired all the time," write "I wake up exhausted and need to rest for two hours before I can do anything. By mid-afternoon, I have to lie down again." Instead of "My memory is bad," write "I forget conversations from the day before. I have to write down appointments or I will miss them. I cannot remember a list of more than two or three items."

Describe what happens when you try to do something, not just that you cannot do it. For example: "I tried to work at a grocery store for one week. By the third day, my back pain was so severe I could not stand for more than 15 minutes at a time. I called in sick on the fourth day and did not go back." That tells the SSA not just that you have back pain, but that you have tried to work and your condition prevented you from continuing.

If your condition varies day to day, say so. Write about your typical day, but also mention when you have good days and bad days. The SSA understands that some conditions are unpredictable. What matters is whether you can work consistently, not whether you can work once in a while.

What Happens After You Submit the Function Report

The SSA will review your answers along with your medical records and any other evidence in your file. If your Function Report and your medical records tell the same story, and that story shows you cannot work, the SSA may approve your claim. If there are gaps or contradictions, they may ask for more information, order a medical exam, or deny your claim.

If you are denied and you appeal, your Function Report becomes part of the record that a judge will review. At a hearing, the judge may ask you to explain your answers or to describe a typical day in more detail. That is why it is important to keep a copy and to be consistent in what you say.

The SSA may also send you a new Function Report later, especially if you have been receiving SSDI for a while. They do this to check whether your condition has improved or worsened. You fill it out the same way: honestly, specifically, and in line with what your doctors have documented.

Common Mistakes People Make on the Function Report

The most common mistake is writing too generally. "I cannot work" does not tell the SSA anything. "I cannot work because I cannot sit for more than 30 minutes without severe back pain, and my job requires sitting at a desk all day" tells them exactly why you cannot work.

Another mistake is overstating your limitations. If you write that you cannot do anything at all, but your medical records show you can do some things, the SSA will assume you are not being truthful. It is better to be honest about what you can do on a good day and what you cannot do on a bad day.

A third mistake is not explaining how your condition affects work specifically. The SSA does not care whether you can watch television or visit a friend. They care whether you can show up on time, follow instructions, concentrate, and work safely. If your condition makes any of those things impossible, explain how.

Frequently Asked Questions

Can I ask my doctor to fill out the Function Report for me?

No. The SSA wants to hear from you, not from your doctor. Your doctor has already provided medical records. The Function Report is meant to capture your own experience of how your condition affects your daily life. You can ask your doctor for help understanding your medical condition, but you must write the answers yourself.

What if I miss the important date on the Function Report?

Call the SSA when ready and ask for an extension. The important date is usually 10 days, but the SSA will often give you more time if you ask before the important date passes. If you miss the important date without asking, the SSA may deny your claim or appeal based on not having the information they requested. If that happens, you can file a new appeal and submit the form late with an explanation.

Should I mention things my doctor did not document?

Only if they are important to your case and you can back them up. If your doctor did not write down something you experienced, it is better to get your doctor to document it now than to mention it on the Function Report without medical support. If you do mention something undocumented, be prepared to explain why your doctor did not write it down and to provide evidence if the SSA asks for it.

Can I submit additional pages if the form does not have enough space?

Yes. If you need more space to explain your answers, attach extra pages and number them clearly. Write your name and Social Security number at the top of each page so the SSA knows which form they belong to. The SSA would rather have complete information than incomplete answers squeezed into small boxes.

What if my condition has gotten worse since I submitted the Function Report?

If you are still in the process process, you can submit updated medical records and ask the SSA to consider them. If you have already been denied and are appealing, you can submit new medical evidence as part of your appeal. If you are already receiving SSDI, you can report changes to your condition, and the SSA may send you another Function Report to reassess your case.
