Social Security Disability Insurance (SSDI) is a federal program that provides monthly income to individuals who have worked, paid into Social Security, and can no longer work due to a qualifying medical condition. The process is complex, the rules are strict, and most first-time applicants are denied — even when they qualify. National Disability connects individuals across all 50 states with experienced disability attorneys who build strong claims from the start and fight denials through every stage of appeal. All services are provided on a no-win, no-fee basis. You pay nothing unless your claim is approved.
To qualify for SSDI, you must meet both medical and work credit requirements set by the Social Security Administration.
You must have a medically determinable condition that prevents you from performing substantial gainful activity, supported by medical evidence such as test results, treatment records, or physician statements. The condition must have lasted — or be expected to last — at least 12 months or result in death.
You earn work credits through the Social Security taxes withheld from your paychecks. Most applicants need at least 20 credits earned in the last 10 years. Younger workers may qualify with fewer credits depending on age and work history.
Our team can review your work history and medical records at no cost to determine whether you meet the SSA’s requirements and identify the strongest path forward for your claim.
Most first-time SSDI applications are denied — not because the applicant doesn’t qualify, but because of fixable problems with how the claim was filed.
The SSA requires detailed, consistent medical documentation. Gaps in treatment, missing records, or vague physician statements are among the most common reasons for denial.
Your condition must be expected to last at least 12 months or result in death. Conditions that may improve or that lack documented prognosis are frequently denied.
If you are still working and earning above the Substantial Gainful Activity threshold set by the SSA, your claim will be denied regardless of your medical condition.
Small mistakes, missing fields, or inconsistencies between your application and your medical records can trigger a denial that has nothing to do with whether you actually qualify.
If you haven’t worked enough recent quarters to accumulate the required work credits, you may not qualify for SSDI — though you may still qualify for SSI.
The SSA maintains a list of qualifying conditions. If your condition isn’t listed, you can still qualify — but it requires a stronger showing that you cannot perform any substantial work.
A denial is not the end of your case. The SSA has a four-stage appeals process, and many claimants who are initially denied are approved on appeal.
A different SSA examiner reviews your original claim and any new evidence you submit. Most reconsiderations are also denied, which is why having an attorney involved from this stage matters.
You present your case before an Administrative Law Judge (ALJ) who reviews your medical evidence, work history, and may hear testimony. This is where the majority of successful appeals are won — and where legal representation makes the biggest difference.
If the ALJ denies your claim, you can request review by the SSA’s Appeals Council. The Council may grant your claim, send it back to an ALJ, or deny review entirely.
If all administrative appeals are exhausted, you may file a civil action in federal district court challenging the SSA’s decision. This is a complex process that requires experienced legal representation.
National Disability connects individuals with experienced SSDI attorneys who handle every stage of the claims and appeals process across all 50 states:
All services are provided on a no-win, no-fee basis. You pay nothing unless your claim is approved.
SSDI is based on your work history — you must have paid into Social Security to qualify. SSI (Supplemental Security Income) is needs-based and does not require a work history, but has income and asset limits. Some individuals qualify for both programs simultaneously.
Initial decisions typically take 3 to 6 months. If denied and you request reconsideration, add another 3 to 6 months. An ALJ hearing can take an additional 12 to 24 months depending on the hearing office. Starting with complete, well-organized documentation helps reduce unnecessary delays at every stage.
You can work while applying, but your earnings cannot exceed the Substantial Gainful Activity (SGA) limit set by the SSA each year. In 2025, that limit is $1,620 per month for non-blind individuals. Earning above this threshold will result in a denial regardless of your medical condition.
The SSA maintains a list of qualifying conditions — called the Blue Book — covering musculoskeletal disorders, cardiovascular conditions, mental health conditions, neurological disorders, cancer, and more. If your condition isn’t listed, you may still qualify by demonstrating that your limitations prevent you from performing any substantial work. Our team can evaluate your specific situation at no cost.
Your monthly SSDI benefit is based on your average lifetime earnings before your disability began — not on the severity of your condition or your current income. The SSA calculates your benefit using your earnings record. In 2025, the average monthly SSDI benefit is approximately $1,580.
You are not required to have an attorney, but studies show that represented claimants are significantly more likely to be approved — particularly at the ALJ hearing stage. An experienced SSDI attorney knows how to present medical evidence effectively, anticipate SSA objections, and avoid the errors that cause most denials.
