SSA-3373 Adult Function Report Mistakes That Can Hurt SSDI Claims
A Social Security disability claim can lose credibility in a few vague sentences. The SSA-3373 Adult Function Report is where Social Security learns how your medical conditions affect the ordinary tasks behind a full workday.
Many applicants focus on diagnoses, test results, and doctor visits. Those records matter, but the form asks a different question: what can you do reliably, safely, and without help? Your answers must give a truthful picture of that daily reality.
Small omissions can create a record that looks stronger than your actual ability to function.
Why the Adult Function Report Carries So Much Weight
The SSA-3373 is not a medical form. It is your account of how pain, fatigue, mental health symptoms, neurological issues, breathing problems, or other conditions limit daily activities.
Social Security uses the report alongside treatment records, work history, and other evidence. The agency’s Social Security forms page lists the current Function Report, Adult, as Form SSA-3373-BK.
It measures function, not the diagnosis name
A diagnosis alone does not explain whether you can sit through an eight-hour shift, use your hands repeatedly, remember instructions, or deal with workplace pressure.
For example, “I have arthritis” gives little useful information. A more complete answer might describe hand swelling after 10 minutes of typing, dropped objects, trouble opening containers, and the need to rest between tasks.
Describe the condition’s effects in terms of activities. Explain frequency, duration, triggers, and what happens after you push through a task.
Social Security looks for sustained ability
A claimant may be able to prepare a sandwich, take a short shower, or drive to an appointment. That does not prove the person can perform competitive work five days a week.
However, an answer that says only “I can cook” or “I drive” can invite the wrong conclusion. Add the missing context. State whether you use a microwave, need someone nearby, take breaks, avoid driving in pain, or require recovery time afterward.
A task done once in a while, with pain or help, is different from a task performed reliably throughout a workweek.
Common SSA-3373 Adult Function Report Errors
The SSA-3373 Adult Function Report asks about the way you live, not the version of life you wish you still had. Claimants often weaken their case when they rush through the questions or try to sound more capable than they are.
Leaving explanations too thin
The form asks how your illnesses, injuries, or conditions limit your ability to work. Writing “I cannot work because of pain” is incomplete.
Identify the work-related limits caused by that pain. For instance, explain whether pain prevents standing, walking, lifting, reaching, concentrating, using a keyboard, dealing with customers, or maintaining attendance.
Avoid broad phrases such as “I have good days and bad days” without details. Explain what changes on each type of day. If bad days occur three times a week, state that. If a flare-up leaves you in bed for hours, include that fact.
Describing an ideal day instead of a typical one
Some people answer based on their best day. Others report what they used to do before illness or injury. Both approaches can distort the record.
Use a representative day. Start with when you wake up, whether you need help getting dressed, how long personal care takes, what chores you attempt, and when symptoms force you to stop.
If your condition varies, say so plainly. For example, someone with migraines may function differently before, during, and after an episode. A person with severe anxiety may shop only with another person and only at quiet times.
Treating household chores as proof of independence
Many people with disabling conditions still try to do some chores. They may have no other choice. The important details are how the task gets done and what it costs physically or mentally.
A person who does laundry may carry one item at a time, use a chair, rest for an hour, or leave baskets for a family member. Those facts belong in the report.

Keep Your Forms and Medical Records Consistent
Contradictions can damage a valid claim. Disability Determination Services may compare the Adult Function Report with your application, treatment notes, work reports, and statements from people who know you.
Consistency does not require identical wording. It requires the same honest account of your limits.
Match the Adult Disability Report
The Adult Disability Report, Form SSA-3368, asks about medical treatment, conditions, work history, and other claim details. SSA provides the Adult Disability Report form for claimants who need to review its questions.
Check dates, diagnoses, medications, doctors, and hospital visits before completing Form SSA-3373. If the function report says your back pain began in 2024, but another form lists 2021, explain the difference if there is one.
The same care applies to statements about daily functioning. Do not tell one part of SSA that you cannot leave home alone, then state elsewhere that you shop independently every week without describing assistance or limits.
Do not overlook the Work History Report
Past jobs matter because Social Security compares your current limits to the demands of prior work. The SSA-3369 Work History Report asks for information that helps the agency understand what your jobs required.
If your former position required frequent lifting, constant standing, computer use, customer contact, or close attention to detail, the function report should accurately explain why your condition now interferes with those demands.
Do not guess at physical job requirements. Review a resume, old job description, or former schedule if available. A clear work history makes functional limits easier to understand.
Medical records should support the same story
Your own statement cannot replace medical evidence. Social Security’s disability guidance explains that applications and related forms help identify impairments and medical sources, while the medical file establishes the underlying condition.
Still, do not assume every limitation appears in a doctor’s note. Tell your providers about side effects, sleep problems, falls, panic attacks, numbness, concentration lapses, and limits at home. Accurate treatment records and a complete function report work together.
Vague Answers Can Make Serious Limitations Disappear
The most damaging answers are often not false. They are incomplete. A short answer may leave out the assistance, breaks, pain, and failed attempts that show why an activity does not translate to work.
Put numbers and time frames where you can
Concrete details give the reviewer a usable picture. You do not need perfect measurements, but reasonable estimates are better than empty labels.
Instead of writing “I cannot walk far,” describe how far you can walk before resting. Instead of “I have trouble concentrating,” state whether you lose focus after 10 minutes, forget instructions, or need reminders for appointments.
Useful details may include:
- How long you can stand, sit, walk, lift, type, or concentrate before symptoms worsen.
- How often symptoms flare and how long recovery takes afterward.
- Whether you miss planned activities because of fatigue, panic, pain, dizziness, or medication effects.
- What happens when you try to complete an activity too quickly or without a break.
Do not inflate limits. Social Security can spot answers that do not fit the overall record. Accurate detail is more persuasive than dramatic language.
Explain help, tools, and changes in routine
The form directs applicants to identify help they receive with activities. Mention assistance from a spouse, adult child, roommate, neighbor, caregiver, or friend.
Also identify braces, canes, walkers, shower chairs, pill organizers, alarms, written reminders, delivery services, or other supports you rely on. These details show how you manage tasks despite limitations.
A claimant may still prepare food, for example, but only with a stool, pre-cut ingredients, and help carrying cookware. The report should show the full process, not only the final meal.
Blank Spaces and Missed Deadlines Create Avoidable Problems
Social Security’s instructions are direct: do not leave questions blank. If an answer is unknown, none, or does not apply, write that response rather than skipping the item.
Read the entire report before you start. Then gather your medication list, medical provider information, calendar, and notes about a usual day.
Use the remarks page when space runs out
The current form includes a remarks section near the end. Use it when a box does not give enough room to explain a limit.
Write the question number before each added explanation. That helps the reviewer connect your note to the right answer.
You can also clarify changes over time. If you stopped driving after a medication change, surgery, worsening vision, or increased anxiety, include when and why that change occurred.
Do not ask your doctor to fill out the form
The Adult Function Report is your statement. The form instructs claimants not to have a doctor or hospital complete it.
A doctor may provide medical records or a separate opinion about functional restrictions. However, your SSA-3373 should describe what you experience and do each day in your own words.
Return the report by the date Social Security gives you. There is no single universal deadline printed on every form package, so follow the date in your notice. If you need more time or have trouble completing it, contact the Social Security office promptly and document the request.
Third-Party Reports Must Tell the Same Truth
Social Security may ask a spouse, relative, friend, or caregiver to complete Form SSA-3380, the Third-Party Function Report. That person’s answers can either support your claim or create questions.
Before someone completes it, discuss the activities they have actually observed. Do not coach them to exaggerate. Instead, help them understand the difference between seeing you wash dishes once and knowing how much pain, rest, or assistance that task required.
Choose someone with firsthand knowledge
The best third-party source sees your daily routine often enough to describe it accurately. A spouse may know about sleep disruption, help with personal care, medication reminders, and recovery after appointments.
A coworker may better explain changes in attendance, pace, lifting ability, memory, or social interaction before you stopped working. Each person should stay within what they personally know.
Their statement should align with your report while using their own observations. Review common SSA-3380 mistakes if someone close to you received a third-party form.
Correct errors before they become part of the record
If you notice an error after submitting the SSA-3373 Adult Function Report, do not ignore it. Write down the correct information, explain the mistake, and contact Social Security about adding clarification to your file.
The agency’s internal guidance allows supplemental information with a Function Report. A prompt correction is better than leaving an inaccurate answer unexplained.
When Legal Help Can Protect an SSDI Claim
A disability lawyer cannot create limitations that do not exist. However, legal guidance can help you identify missing facts, spot conflicts between forms, and submit evidence that accurately supports your claim.
Help is often useful when you have several conditions, a long work history, mental health symptoms, a prior denial, or records that do not fully describe your daily limits. It can also matter when Social Security requests more forms while you are overwhelmed by treatment.
Florida claimants should take every SSA request seriously. A strong report connects real symptoms to dependable work limits without overstating the facts.
Final Thoughts
The SSA-3373 is a record of what life requires from you when your health limits ordinary activity. Clear answers about help, breaks, failed attempts, and recovery time give Social Security a more accurate account of your capacity.
A complete Adult Function Report does not guarantee SSDI approval. Yet an honest, detailed, and consistent form prevents avoidable mistakes from obscuring the limitations that medical evidence supports.
