The Function Report Is Read By a Trained Examiner, Not Your Doctor

The Disability Function Report (also called the Adult Function Report or Child Function Report depending on your age) is a form Social Security sends you after you file for SSDI or SSI. It asks you to describe what you can and cannot do in daily life—how you dress, cook, manage money, leave your home, interact with others. A disability examiner will read your answers alongside your medical records. That examiner is trained to spot inconsistencies between what you write and what your doctors say, and between what you write and what your medical history shows you have actually done.

Many people think the form is a chance to convince Social Security how sick they are. It is not. It is a factual record. Exaggerating, minimizing, or describing yourself in ways your medical file contradicts will not persuade the examiner—it will create doubt about your credibility, and doubt is what denials are built on.

Key Takeaways

  • Never describe abilities you do not have or disabilities you do not experience; the examiner will cross-check your answers against your medical records and any work history.
  • Do not say you cannot do something if your medical records show you have done it recently, even if it was difficult or caused you pain afterward.
  • Avoid vague language like "I can barely function" or "I am in constant pain"; instead, describe the specific task and what happens when you try it.
  • Do not claim you have never left your home or never spoken to anyone if you have; the examiner knows that total isolation is rare and will question claims that sound extreme.
  • Write what is true on the day you fill out the form, not your worst day or your best day, and explain how your condition changes from day to day if it does.

Do Not Claim You Cannot Do Things You Actually Do

This is the most common reason examiners find a function report unreliable. If your medical records show you attended a doctor's appointment last month, drove yourself there, sat in a waiting room, and answered questions for 20 minutes, you cannot write that you cannot sit for more than five minutes or that you cannot drive. If you have posted on social media in the past few weeks, you cannot say you cannot use a computer or phone. If you have been to a grocery store, you cannot say you never leave your home.

The examiner is not trying to catch you in a lie. They are trying to understand what your actual functional limits are. If you write that you cannot sit for 30 minutes but your medical file shows you sat through a two-hour appointment three weeks ago, the examiner will assume either that you exaggerated on the form or that your condition improved—and if it improved, that changes what Social Security thinks you can do for work.

If you did something but it was extremely difficult or caused a flare-up afterward, say that. "I can drive to the store, but I can only do it once a week because my back pain gets worse for two days after" is credible. "I cannot drive" is not, if you have driven recently.

Do Not Use Vague Language Or Extreme Statements

Phrases like "I am in constant pain," "I can barely function," "I cannot do anything," or "I am completely disabled" sound like you are trying to persuade rather than describe. Examiners read hundreds of these forms. Extreme language without specific detail makes them skeptical.

Instead, describe what actually happens. "I have pain in my lower back that starts after I stand for 15 minutes. If I stand longer, the pain gets sharp and I have to sit down" is specific and credible. "My pain is unbearable" is not—unbearable to whom, and for how long?

The same applies to mental health and cognitive limits. Do not write "I cannot think" or "I am too depressed to do anything." Write what you actually experience: "I have trouble concentrating for more than 10 minutes at a time," or "On days when my depression is bad, I stay in bed and do not answer the phone or door," or "I forget what I was doing mid-task and have to start over."

Do Not Describe Your Worst Day As Your Typical Day

Your condition may fluctuate. Some days are worse than others. The function report asks about what you can do, and the examiner needs to know what you can do on an average day, not on your worst day or your best day.

If your condition varies, say so. "Most days I can walk for 10 minutes before my knee swells. On bad days, I can only walk for five minutes. On good days, I might manage 15 minutes, but I pay for it the next day." That tells the examiner something real about your limits. "I cannot walk at all" does not, if you can walk on some days.

The same is true for mental health conditions that have good days and bad days. If you have bipolar disorder and some days you are functional and some days you cannot get out of bed, describe both. Do not pick the worst day and pretend it is every day.

Do Not Claim Total Isolation Unless It Is True

Examiners know that total social isolation is rare, even among people with severe disabilities. If you write that you never leave your home, never speak to anyone, never use the phone, and have no contact with family, the examiner will be skeptical—not because isolation is impossible, but because it is uncommon enough that it needs to match your medical records.

If you have severe agoraphobia or are homebound, your medical file should document that. Your doctor's notes should mention that you do not leave home. If your medical records do not support total isolation but your function report claims it, the examiner will assume you exaggerated.

Be honest about your actual social contact. "I do not work and rarely leave my home, but I talk to my sister on the phone twice a week and my neighbor brings me groceries" is credible. "I have no contact with anyone" is not, if you have any contact at all.

Do Not Contradict What Your Doctors Have Written

Before you fill out the function report, ask your doctor for copies of their recent notes. Read what they wrote about your abilities and limitations. If your doctor wrote that you can walk a quarter mile, do not write that you cannot walk at all. If your doctor noted that your memory is intact, do not claim you cannot remember anything.

You do not have to agree with everything your doctor wrote, and you can add detail. But if you directly contradict your medical records, the examiner will trust the records, not the form. Your doctor has examined you and documented findings. You are filling out a form from home.

If you think your doctor's notes are wrong, get them corrected before you submit the function report. Ask your doctor to update their notes or write a letter explaining what they actually observed. Do not just contradict them on the form.

Do Not Describe Symptoms Your Medical Records Do Not Support

If your medical file does not mention a symptom, do not suddenly describe it on the function report. If you have never told a doctor that you have seizures, do not write on the form that you have seizures. If your medical records show no diagnosis of cognitive impairment, do not claim you cannot remember or think clearly.

Social Security will ask your doctor about anything you report on the function report that is not already in the medical file. If your doctor says "I have never observed that" or "The patient has never mentioned that," the examiner will assume you invented it or exaggerated it to strengthen your case.

If you have a symptom that your doctor does not know about, tell your doctor first. Get it documented in your medical record. Then describe it on the function report. That way, when Social Security asks, your doctor can confirm it.

Do Not Minimize Symptoms You Actually Have

This is the opposite problem, but it happens. Some people downplay their symptoms because they are embarrassed, or because they do not want to seem like they are complaining, or because they are used to pushing through pain. On the function report, do not do this.

If you have panic attacks, say so. If you have trouble with incontinence, say so. If you cannot read because of vision problems, say so. These are not shameful. They are medical facts that Social Security needs to know to understand whether you can work.

The function report is not a conversation with your boss or your family. It is a medical document. Be as honest about the hard things as you would be with a doctor.

Frequently Asked Questions

What if I did something once but I cannot do it regularly?

Describe it that way. "I went to my daughter's wedding last month, but I had to sit down most of the time and my pain was severe for three days after" tells the examiner that you can do something occasionally under specific circumstances, but not regularly. That is different from "I cannot sit" and the examiner will understand the difference.

Should I mention things I could do before I became disabled?

Only if it helps explain your current limits. "I used to work as a carpenter but I cannot do that anymore because I cannot stand for more than 30 minutes" is relevant. "I used to be able to run a marathon" is not, unless it shows how much your condition has changed and that change is recent and documented in your medical records.

What if my condition is getting worse or better?

Describe the trend. "My arthritis has gotten worse over the past year and I can do less now than I could six months ago" or "My depression has improved with medication and I am doing more than I was" tells the examiner what is actually happening. Do not hide changes—they matter to Social Security's decision.

Can I have someone else fill out the form for me?

You can have help understanding the questions or organizing your thoughts, but you must sign the form and the answers must be yours. If the examiner suspects someone else wrote it or that you did not understand what you were signing, they may ask you questions to verify your answers. Be prepared to explain what you wrote.

What happens if the examiner thinks I exaggerated?

They will note it in the file and it will affect how much weight they give your testimony. If your medical records support your claims, the examiner will trust the records. If they do not, the examiner may deny your case or ask your doctor for more information. Being credible on the function report matters because it is one of the few places where you speak directly to Social Security.
