What Is Cause of Loss
Cause of loss in a Social Security disability claim is the medical condition or event that directly caused your inability to work. The SSA needs to establish a clear link between your diagnosed condition and your functional limitations. This isn't just about naming a disease, it's about proving that specific condition prevents you from performing any substantial gainful activity, which the SSA defines as earning more than $1,550 per month (for 2024).
Why It Matters
The SSA denies approximately 65% to 70% of initial SSDI and SSI applications. A major reason is insufficient medical evidence establishing cause of loss. When you file, you must prove the specific condition caused your work stoppage, not just that you stopped working. At an Administrative Law Judge (ALJ) hearing, your cause of loss becomes the central question. The ALJ will review your medical records, test results, and functional capacity evaluations to determine whether your documented condition actually prevents work.
Your cause of loss also determines your back pay calculation. Once approved, back pay runs from your established onset date (EOD) to your approval date. If the SSA questions your cause of loss, they may assign a later onset date, reducing your back pay significantly. A claimant approved with an EOD two years before approval could receive $30,000 to $40,000 in back pay, while one with a disputed onset date might receive half that amount.
How It Works
Here's the process the SSA follows with cause of loss:
- Medical evidence gathering: Submit treatment records, diagnostic test results (MRI, CT scan, blood work), and specialist reports that document your condition. The SSA weighs treating source opinions heavily, so statements from your regular doctor carry more weight than evaluations from doctors who examined you once.
- Functional limitations assessment: The SSA uses a Residual Functional Capacity (RFC) form to translate your medical condition into work restrictions. If your cause of loss is degenerative disc disease, the RFC will specify how much you can sit, stand, lift, and carry.
- Onset date establishment: The SSA determines when your condition became severe enough to prevent work. This date directly affects back pay eligibility. You can typically claim benefits starting 12 months before your application date.
- ALJ review: If denied initially, an ALJ will examine whether your cause of loss documentation is sufficient. At this stage, having recent medical records (within the last 60 days of the hearing) is critical.
Medical Evidence Requirements
The SSA requires specific types of evidence for cause of loss:
- Clinical findings from examinations (not just patient complaints)
- Objective test results and imaging reports
- Treatment notes showing ongoing management of your condition
- Medication lists demonstrating medical necessity
- Statements from treating physicians about your work capacity
- For mental health conditions, psychological or psychiatric evaluations with specific functional limitations noted
Appeals Council and federal court decisions show that causes of loss without objective medical support face higher denial rates. Subjective complaints alone (pain, fatigue, cognitive difficulties without test documentation) rarely succeed.
Common Questions
- Can I have multiple causes of loss? Yes. The SSA approves claims based on combined conditions if the total impact prevents work. A claimant with both arthritis and hypertension affecting kidney function might be approved on the combined impact even if neither alone meets the severity threshold.
- What if my cause of loss improved after I applied? Improvement doesn't automatically disqualify you if you remain unable to work. However, the SSA will request current medical records at your continuing disability review (typically every 3 years for those expected to improve). Document any residual limitations even if your condition has stabilized.
- How recent must my medical evidence be? For ALJ hearings, records within 60 days of the hearing date carry the most weight. Older records still matter, but recent treatment history is essential. If you haven't seen a doctor in a year, get an examination before your hearing.
