An SSDI questionnaire is one of the forms Social Security sends after you apply for disability benefits so the agency can understand what your condition actually stops you from doing. The two main ones are the Function Report (SSA-3373-BK), which covers your daily life and limitations, and the Work History Report (SSA-3369-BK), which covers every job you held in the 15 years before your disability began.1Social Security Administration. Function Report – Adult – Form SSA-3373-BK2Social Security Administration. Work History Report – Form SSA-3369-BK Roughly two-thirds of initial SSDI applications are denied, and vague or incomplete answers on these forms are one of the easier problems to avoid. Fill them out with specific numbers and concrete examples, and keep your answers consistent with what your medical records already say.
The Function Report
The Function Report walks through your entire day, from waking to bedtime, and asks about personal care, cooking, chores, shopping, social activities, handling money, and following instructions.1Social Security Administration. Function Report – Adult – Form SSA-3373-BK Your answers feed into what Social Security calls your residual functional capacity, meaning the most you can still do despite your condition.3Social Security Administration. Code of Federal Regulations 416.945 – Your Residual Functional Capacity
Describe a Typical Day, Not Your Best or Worst
The form asks for a typical day. Describe the day that happens most often. Include how long it takes you to get dressed, whether you need help bathing, and whether you have to rest between tasks. If pain or fatigue forces you to lie down for two hours after showering, say that. If you need reminders to take medication, note who reminds you and how often.4Social Security Administration. Function Report – Adult – Form SSA-3373-BK
Use specific numbers. “I can walk about one block before the pain in my lower back forces me to stop” is far more useful than “I have trouble walking.” The same goes for lifting, standing, and sitting. If you can stand for 10 minutes before needing to sit, write that. If you can carry a gallon of milk but not a bag of groceries, that gives the examiner a concrete weight reference.
Include Mental and Cognitive Limitations
Many claimants focus on physical restrictions and underplay mental health. Social Security evaluates mental functioning across four areas: understanding, remembering, or applying information; interacting with others; concentrating, persisting, or keeping pace; and adapting or managing yourself.5Social Security Administration. 12.00 Mental Disorders – Adult A mental impairment can qualify on its own if it causes an extreme limitation in one of these areas or marked limitations in at least two.
If you struggle to follow written instructions, have panic attacks in public, can’t concentrate long enough to finish a TV show, or find it hard to handle changes in routine, put those details on the form. Be concrete. “I cannot follow a recipe with more than three steps” tells the examiner something measurable. “I have memory problems” does not.
List Medications and Their Side Effects
Before you start writing, gather a full list of prescriptions with dosages. Side effects like drowsiness, dizziness, nausea, or brain fog can be as disabling as the underlying condition, and the Function Report is where you connect them to your day. If a pain medication makes you too groggy to drive by 2 p.m., that is a work-relevant limitation. Also compile contact information for every treating physician, specialist, and clinic so the agency can verify your medical records.
The Work History Report
The Work History Report asks you to list every job from the 15 years before your disability onset, with job titles, dates, the type of business, and a breakdown of daily tasks.2Social Security Administration. Work History Report – Form SSA-3369-BK For each position, you estimate hours spent sitting, standing, walking, climbing, stooping, and handling objects, plus the heaviest weight you lifted and how often.
Describe your duties at their most demanding, not on a light day. If you were a retail manager who sometimes had to unload delivery trucks and carry 50-pound boxes, include that even if it only happened twice a week. The examiner needs the full physical picture. If a job required supervising other employees, note how many and what that involved, because supervisory skills can transfer to other occupations later in the evaluation.
Don’t leave any field blank. If a question doesn’t apply, write “N/A” rather than skipping it. A blank can look like you forgot or chose not to answer, and examiners notice gaps. Avoid vague descriptions like “office work.” Specify: answering phones, typing reports, filing documents, lifting file boxes.
The Third-Party Function Report
Social Security sometimes sends a separate form, the Third-Party Function Report (SSA-3380-BK), to someone who knows you well. This could be a spouse, adult child, friend, former coworker, or caregiver. The form covers the same ground as your own Function Report but asks for that person’s independent observations, not your self-assessment.6Social Security Administration. Function Report – Adult – Third Party
The form instructs the third party not to ask you for answers. SSA wants an outside perspective on how your condition affects daily life, so choose someone who sees you regularly and can describe specific examples. A spouse who watches you struggle to get out of bed every morning provides more useful information than a sibling who visits once a month. Doctors and hospital staff are not eligible to complete this form.
Consistency between your Function Report and the third-party report strengthens your claim. If you say you can’t stand more than five minutes and your spouse independently reports the same thing, that corroboration carries weight. Contradictions raise red flags.
How to Submit the Forms and Meet the Deadline
You can submit completed questionnaires by uploading them through the SSA’s online Upload Documents tool, faxing them, or mailing them to your local Social Security office.7Social Security Administration. Social Security Forms If SSA or the state Disability Determination Services office sent you a cover sheet with a barcode, include it as the first page of any fax or upload. That barcode routes your documents into the correct electronic disability folder.8Social Security Administration. Use Electronic Records Express to Send Records Related to Disability Applications
The cover letter that arrives with your forms includes a return deadline. The window is typically short, and missing it can delay your claim or force the agency to decide without your input. If you need more time, call the office listed on the letter and ask for an extension before the deadline passes. Keep a copy of everything you submit along with fax confirmations or upload receipts.
How Examiners Use Your Answers
After the field office verifies your non-medical eligibility, your case goes to the Disability Determination Services office in your state, where an examiner and a medical or psychological consultant review your questionnaire answers alongside your medical records.9Social Security Administration. Disability Determination Process They are looking for consistency. If you report that you can barely walk across a room, but your doctor’s notes describe a normal gait during office visits, the examiner will notice and it will need to be resolved.10Social Security Administration. Evidence Evaluation
Your Function Report shapes the residual functional capacity assessment. Your Work History Report is what the examiner compares that capacity against when deciding whether you could return to any of your past jobs, and, if not, whether you could adjust to other work considering your age, education, and experience.11Social Security Administration. Code of Federal Regulations 404.1520 – Evaluation of Disability in General That is why vague answers hurt: they leave the examiner without the concrete facts needed to rule work in or out.
When the record has conflicts or gaps that could change the outcome, the examiner may contact your doctor for clarification or schedule a consultative examination at the government’s expense. A consultative examination is a one-time appointment with a doctor or psychologist chosen by SSA to evaluate limitations the existing evidence doesn’t fully address.12Social Security Administration. Code of Federal Regulations 404.1519 – The Consultative Examination
Be Honest: Penalties for False or Omitted Information
Exaggerating limitations or hiding relevant information is not just risky for the claim. Under the Social Security Act, knowingly making a false statement or omitting a material fact can result in a civil penalty of up to $5,000 per violation, or up to $7,500 if you are a claimant representative, translator, or medical provider. The agency can also impose an assessment of up to twice the amount of any benefits paid as a result of the false information.13Social Security Administration. Social Security Act Title 11 Section 1129 – Civil Monetary Penalties and Assessments for Titles II, VIII, and XVI Those base amounts are adjusted upward each year for inflation.
The penalty applies to knowingly omitting information as well. If you leave out a job from your Work History Report because its physical demands would undermine your claim, that omission can be treated the same as a false statement. The Office of the Inspector General can initiate penalty proceedings up to six years after the violation, and if a penalty becomes final, SSA can collect by withholding benefits, garnishing wages, offsetting tax refunds, and reporting the debt to credit bureaus.14Social Security Administration. Civil Monetary Penalty – Overview
The practical lesson is to be honest and thorough. If your condition genuinely limits you, describe those limitations with specifics. If a question doesn’t apply or you are unsure, say so rather than guessing or embellishing.
If the Claim Is Denied
An initial denial doesn’t end the case. Social Security provides four levels of appeal, and you have 60 days from the date you receive each denial notice to request the next level. The agency assumes you receive the notice five days after the date printed on it, so the effective window is 65 days from the notice date.15Social Security Administration. Appeals Process The levels are reconsideration by a different DDS examiner, a hearing before an administrative law judge, Appeals Council review, and federal court.
Your original questionnaire answers stay in the record at every level. If your condition has worsened since you completed the forms, you can submit updated information. Missing the 60-day deadline doesn’t permanently bar an appeal, but you will need to show good cause for the delay.16Social Security Administration. Handbook Section 535 – How to Submit a Late Request for Reconsideration Filing a new application instead of appealing resets the process, which means longer wait times and the risk of losing months of potential back benefits.
