Ankylosing Spondylitis VA Disability Rating
Diagnostic Code 5240 · 38 CFR §4.71a
What Is It?
Ankylosing spondylitis is a chronic inflammatory condition that primarily targets the spine. Over time the vertebrae can fuse together, reducing flexibility and creating a hunched-forward posture. It often begins in the sacroiliac joints and moves upward. Many veterans develop symptoms during or shortly after service due to physical demands and repetitive spinal stress.
Rating Criteria
| Rating | Criteria |
|---|---|
| 100% | Unfavorable ankylosis of the entire spine where the spine is fixed in a flexed or extended position making it impossible to maintain an upright posture. |
| 40% | Forward flexion of the thoracolumbar spine limited to 30 degrees or less, or favorable ankylosis of the entire thoracolumbar spine. |
| 20% | Forward flexion of the thoracolumbar spine greater than 30 degrees but not greater than 60 degrees, or the combined range of motion is 120 degrees or less, or there is muscle spasm or guarding severe enough to cause abnormal gait or abnormal spinal contour. |
Evidence Needed
- Rheumatology records showing diagnosis and treatment history
- Imaging such as X-rays or MRI demonstrating sacroiliitis or vertebral fusion
- Range of motion measurements from recent medical evaluations
- Documentation of flare-ups including frequency, duration, and functional impact
- Statements describing how spinal stiffness affects daily activities and work
C&P Exam Tips
- Schedule your exam for a time when morning stiffness is most apparent if possible
- Report all flare-up details including how often they happen and how long they last
- Describe pain during movement and any positions you cannot achieve
- Mention any breathing difficulty caused by chest wall rigidity
- Bring imaging studies that show progression of the disease
How to File
File under DC 5240. Include rheumatology records, imaging showing vertebral changes, and range of motion testing. If you have secondary conditions like eye inflammation or breathing problems, file those as secondary claims linked to your ankylosing spondylitis.
Common Mistakes
Not documenting morning stiffness duration which is a hallmark symptom Failing to report chest expansion limitations that can support a higher rating Missing secondary claims for eye conditions or breathing issues that commonly accompany this disease Not requesting imaging that shows disease progression over time
Frequently Asked Questions
Can I get a rating for ankylosing spondylitis if I was diagnosed after service?
Yes. If you can show symptoms began during service or within a reasonable time after discharge, and a medical professional links the condition to your service, you can still establish service connection.
Does ankylosing spondylitis qualify for TDIU?
It can if the condition prevents you from maintaining substantially gainful employment. The spinal rigidity and chronic pain associated with advanced cases often support TDIU claims.
