The Social Security Administration denies roughly two out of every three SSDI applications at the initial stage. For most people, this is devastating news — especially when they're already dealing with a disability that has cost them their ability to work. But a denial is not the end of the road. Understanding why claims get denied is the first step to building a stronger case.

⚠️ Note: This article is for educational purposes only and does not constitute legal advice. Disability law is complex. Consult a licensed disability attorney for guidance specific to your situation.

Reason #1: Insufficient Medical Evidence

The single most common reason SSDI claims are denied is a lack of sufficient medical documentation. The SSA needs detailed, consistent medical records that clearly establish both your diagnosis and how it limits your ability to work. A single doctor's note saying "patient is disabled" is not enough.

✅ What to do: See your treating physicians regularly and ensure they document your functional limitations in detail — not just your diagnosis. Get specific records that describe what you cannot do: how long you can sit, stand, walk, lift, concentrate.

Reason #2: Earning Too Much (SGA Limit)

If you are working and earning above the Substantial Gainful Activity (SGA) threshold, the SSA will deny your claim outright regardless of your disability. In 2026, the SGA limit is $1,620/month for non-blind applicants and $2,700/month for blind applicants.

✅ What to do: If you are working above SGA, consider whether a Trial Work Period applies to your situation. A disability attorney can help you navigate this.

Reason #3: The Condition Is Not Expected to Last 12 Months

SSDI requires that your disability either has lasted or is expected to last at least 12 consecutive months, or result in death. Short-term or temporary conditions — even severe ones — generally do not qualify.

✅ What to do: Make sure your medical records document the long-term or permanent nature of your condition. Your doctor's written prognosis regarding duration is critical.

Reason #4: Failure to Follow Prescribed Treatment

If the SSA determines that you are not following your doctor's prescribed treatment without good cause, they may deny your claim on the grounds that your condition could improve with treatment. This catches many applicants off guard.

✅ What to do: Follow your prescribed treatment plan consistently. If you cannot afford treatment or have religious/medical reasons for not following it, document those reasons thoroughly.

Reason #5: Not Enough Work Credits

SSDI requires a minimum number of work credits based on your age at the time of disability. Generally you need 40 credits (10 years of work), with 20 earned in the last 10 years. Younger workers need fewer credits. If you don't meet this requirement, SSDI is not available — but SSI may be.

✅ What to do: Check your Social Security statement at ssa.gov to verify your work credits. See our full work credits guide for details. If you don't have enough for SSDI, apply for SSI instead.

Reason #6: The SSA Thinks You Can Do Other Work

Even if you can no longer do your previous job, the SSA may deny your claim if they believe you can perform other types of work that exist in the national economy. This is called the "vocational" step of the five-step evaluation process — and it's where many claims that seemed strong on medical grounds get denied.

✅ What to do: A disability attorney can challenge vocational assessments and present evidence that no suitable jobs exist given your age, education, experience, and functional limitations. This is one of the highest-value things an attorney does.

What to Do After a Denial

If your claim is denied, do not give up. The approval rate at the hearing level (after appeal) is significantly higher than at the initial application stage. See our full guide to the appeals process for what happens at each stage. In brief:

  • File a Request for Reconsideration within 60 days of your denial notice
  • If reconsideration is denied, request a hearing before an Administrative Law Judge (ALJ)
  • Hire a disability attorney — approval rates with representation are significantly higher
  • Continue seeing your doctors and building your medical record during the appeal
  • Do not miss any SSA deadlines — missed deadlines can permanently bar your appeal
