Can You Get SSDI for Chiari Malformation?
TL;DR: Yes. Chiari malformation occurs when brain tissue extends into the spinal canal, causing headaches, balance problems, difficulty swallowing, sleep apnea, weakness, and pain. Chiari I is the most common type in adults. Even after decompression surgery, many people have persistent symptoms that prevent work. The SSA evaluates Chiari under the neurological listings, primarily Listing 11.08 (spinal cord disorders) or 11.17 (neurodegenerative disorders).

Chiari malformation pushes the cerebellar tonsils downward through the opening at the base of the skull, compressing the brainstem and spinal cord. This compression causes a wide range of symptoms because the affected area controls balance, coordination, swallowing, breathing, and the flow of cerebrospinal fluid. Many people also develop a syrinx (fluid-filled cavity in the spinal cord), which causes additional neurological problems.
SSA Listings for Chiari Malformation
| SSA Listing | Condition | Key Requirements |
|---|---|---|
| 11.08 | Spinal cord disorders | Motor dysfunction in two extremities causing extreme limitation |
| 11.17 | Neurodegenerative disorders | Progressive motor or cognitive dysfunction with marked limitation |
| 11.19 | Syringomyelia | If a syrinx is present with documented neurological deficits |
SSA evaluates disability claims using the Blue Book, which lists qualifying conditions and the specific criteria each must meet. If your condition matches a Blue Book listing, approval is more straightforward. Even if your condition does not match a Blue Book listing exactly, you can still qualify through a medical-vocational allowance. This considers your age, education, work experience, and functional limitations together. Consistent treatment records are critical. SSA looks for ongoing documentation showing your condition limits your ability to work, not just a single diagnosis.
Medical Evidence the SSA Needs
- MRI showing cerebellar tonsillar herniation and degree of descent
- MRI of spine if syringomyelia is present
- CSF flow study showing blockage
- Neurological examination documenting specific deficits
- Sleep study if sleep apnea is present
- Swallowing study if dysphagia is reported
- Surgical records if decompression was performed
- Post-surgical imaging and functional assessment
- Documentation of headache pattern and severity
Request your medical records directly from each provider rather than relying on SSA to gather them. SSA requests can take months, and records sometimes get lost in the process. Include records from every provider you have seen for your disabling conditions, even if a visit seemed minor. Gaps in treatment history are one of the most common reasons for denial. Medical records from the past 12 months carry the most weight, but older records help establish the onset date. A treatment history spanning several years shows the condition is persistent, not temporary.
Common Denial Reasons
- Decompression surgery expected to resolve symptoms. The SSA may assume surgery cures Chiari. Document persistent symptoms post-surgery.
- Chiari I with minimal herniation. Mild tonsillar descent (less than 5mm) may be dismissed. The degree of CSF flow blockage matters more than millimeters of descent.
- Symptoms attributed to other conditions. Headaches and fatigue are common in many conditions. Tie your symptoms specifically to the Chiari with neurological evidence.
A denial does not mean your case is over. About 2 out of 3 initial SSDI applications are denied, and many of those denials are overturned on appeal. Read your denial letter carefully. It tells you exactly why SSA denied your claim. The most common reasons are insufficient medical evidence and SSA determining you can still perform some type of work. You have 60 days from the date on your denial letter to file an appeal. Missing this deadline means starting over from scratch, so mark it on your calendar immediately.
Compassionate Allowance
Chiari malformation is not on the Compassionate Allowance list.

Function Report Tips
- Describe headaches: triggers (coughing, straining, bending), location (back of head), severity
- Detail balance and coordination problems with specific examples
- Explain swallowing difficulties if present
- Describe numbness, tingling, or weakness in hands and arms
- Note sleep problems and daytime fatigue
- If you had surgery, explain what improved and what did not
Chiari claims need MRI evidence linked to functional limitations. ClaimPath creates SSA-compliant disability documents for $79, saving the 25% attorney contingency.
Related Condition Guides
Report any changes within 10 days of the change occurring. This includes starting or stopping work, changes in your medical condition, moving to a new address, or receiving other benefits. You can report changes online through your my Social Security account, by calling SSA at 1-800-772-1213, or by visiting your local SSA office. Keep a record of what you reported and when. Failing to report changes can result in overpayments. SSA will recover overpayments by withholding future benefits, and in some cases, overpayments can reach thousands of dollars.
What to Do Next
- Check the date on your denial letter and mark your 60-day appeal deadline on a calendar. Missing this window means restarting the entire process.
- Request a complete copy of your SSA file (called the 'exhibit file') so you can see exactly what evidence the reviewer had, and identify any gaps you need to fill.
- Get an updated RFC form from your treating doctor that addresses the specific reasons listed in your denial. If SSA said you can do sedentary work, your doctor needs to explain why you cannot.
- Contact a disability attorney for a free case evaluation. Most work on contingency, so you pay nothing unless you win.
