Most SSDI denials come down to the record, not the person. The Social Security Administration (SSA) denies claims when the medical evidence is thin or inconsistent, when earnings are over the limit, when a deadline or form is missed, or when the condition is not shown to last 12 months. Most of these problems can be fixed, usually on appeal.
Below are the ten reasons that come up most, and what generally addresses each one.
The short answer
A first denial is common. For disabled-worker applications filed from 2014 through 2023, SSA’s Annual Statistical Report on the SSDI Program, 2024, found that the share of applicants awarded benefits at the initial level ranged from 18 to 21 percent. The full figure and source are in our statistics report. Results vary and past outcomes do not predict any individual result.
SSA looks at far more than a diagnosis. It checks work and earnings, medical evidence, treatment history, how you function, and whether you returned every form. A gap in any of those can lead to a denial, even when the disability is real. The good news is that most of the reasons below are about evidence and process, which you can work on.
1. Not enough medical evidence
This is the most common problem. SSA needs objective evidence, such as exam findings, imaging, test results and treatment notes from acceptable medical sources, that shows how your condition limits your ability to work. Your own description matters, but SSA will not find anyone disabled based on symptoms alone.
What helps: List every provider, clinic and hospital on your application, with dates. Ask your treating providers to note specific limits in their records, not just a diagnosis. If you have records at home, send copies.
2. Gaps in treatment
Long stretches without care can lead SSA to doubt how severe your condition is. SSA’s rules say it must consider the reasons before holding infrequent treatment against you. Those reasons can include not being able to afford treatment, having no access to low-cost care, side effects worse than the symptoms, or a mental condition that makes it hard to understand the need for treatment.
What helps: Keep appointments, and if you have a gap, make sure the reason is written down by your provider or explained in your forms. Community health centers and sliding-scale clinics can help fill gaps.
3. Earnings above the substantial gainful activity limit
SSA’s first question is whether you are working above the substantial gainful activity (SGA) level. In 2026, SGA is $1,690 a month, or $2,830 a month if you are statutorily blind. If you earn more than that, SSA generally finds you are not disabled, whatever your medical condition.
What helps: Before you apply, look honestly at your current earnings. If you are working part time below SGA, describe any special conditions, such as extra breaks, a helper, or frequent absences, because SSA also looks at what your work shows about your abilities.
4. Missed deadlines
You generally have 60 days after you receive a denial notice to appeal, and SSA assumes you received it 5 days after it was mailed. Miss that window without a good reason and the denial becomes final.
What helps: File the appeal as soon as you can. You do not need every record in hand to file, and you can add evidence after. If you already missed a deadline, ask SSA for an extension right away and explain why in writing. Our appeal guide covers each deadline.
5. Not following prescribed treatment
SSA can deny a claim if you do not follow treatment your medical source prescribed, without a good reason, when that treatment is expected to restore your ability to work. SSA considers your physical, mental, educational and language limitations when deciding whether a reason is acceptable. Its rules list examples such as religious beliefs, a surgery that already failed once, or a treatment that is very risky.
What helps: If you declined or stopped a treatment, tell your provider why, so it is in the record. Side effects, cost and fear of a risky procedure should be documented, not just mentioned at a hearing.
6. Short expected duration
SSA’s definition of disability requires that your condition has lasted, or is expected to last, at least 12 continuous months, or is expected to result in death. Claims filed shortly after an injury or surgery are often denied because SSA expects improvement within a year.
What helps: Ask your provider for a realistic prognosis in the record. If a year passes and you have not recovered, an appeal with updated records shows the condition did last.
7. Missing or unreturned SSA forms
During a claim, SSA sends questionnaires about your daily activities and past work, requests for records, and sometimes an appointment for a consultative exam with a doctor it pays. If you do not return the forms or attend the exam, SSA may decide your claim on whatever incomplete evidence it has.
What helps: Open every letter from SSA and from your state’s disability agency. Return forms by the date given, call if you cannot make an exam, and keep copies of everything you send.
8. Inconsistent function reports
SSA compares what you say on your forms, what your providers write, and what you say at a hearing. If your function report says you cannot stand for ten minutes, but a medical note describes you working in the yard all afternoon, SSA will weigh the conflict.
What helps: Describe your limits accurately, including good days and bad days. Explain how often bad days happen. Make sure your providers know about your day-to-day limits so their notes reflect them.
9. Condition not documented by an acceptable medical source
To establish that you have a medically determinable impairment, SSA needs evidence from an “acceptable medical source.” That includes licensed physicians and psychologists, and, for claims filed on or after March 27, 2017, licensed advanced practice nurses, physician assistants and audiologists within their scope of practice. Other sources, such as chiropractors or counselors, can help show how you function, but they cannot establish the diagnosis on their own.
What helps: Make sure at least one acceptable medical source has examined you and documented the condition. If most of your care is from other providers, a visit to a physician or psychologist who will review your history can fill the gap.
10. Filing a new application instead of appealing
Many people respond to a denial by starting over. That usually sends the claim back to the same first-level review, and it can cost back pay. An appeal keeps your original application date. SSDI can pay up to 12 months before the month you applied, so a new, later application date can shrink that window. SSI cannot pay for any month before you applied.
What helps: Appeal within 60 days. Use the appeal to fix the problems on this list: add missing records, explain treatment gaps and correct any inconsistencies.

Common questions
Is it normal to be denied the first time?
Yes. Most applicants are not approved at the initial level. A first denial does not mean your claim lacks merit.
What is the most common reason for denial?
Problems with the medical evidence: records that are missing, out of date, or that do not show how your condition limits your ability to work.
Can I fix a denial without starting over?
Usually, yes. Appealing lets you add new evidence and explain gaps while keeping your original application date.
Can a technical denial be appealed?
Yes. A denial based on work credits or earnings can be appealed like a medical denial. Check the notice for the reason, and check your earnings record for errors.
