VA Disability Rating for Irritable Bowel Syndrome (IBS): Complete Guide to Getting Your Claim Approved

Bottom Line Up Front

Irritable Bowel Syndrome is rated under Diagnostic Code 7319 with ratings of 0%, 10%, or 30%. Most veterans receive 10-30% depending on symptom severity. IBS is very commonly claimed as secondary to PTSD, anxiety, or depression (the gut-brain connection is well-established). It's also a Gulf War presumptive condition. The key is documenting symptom frequency and impact on daily life. Claims typically take 3-6 months.

What Is IBS and How Does Military Service Cause It?

IBS is a chronic disorder affecting the large intestine, causing abdominal pain, cramping, bloating, gas, and changes in bowel habits.

Types:

• IBS-D: Diarrhea predominant
• IBS-C: Constipation predominant
• IBS-M: Mixed

Secondary service connection:

• PTSD: Strong gut-brain connection
• Anxiety/depression: Stress affects gut function
• Medications: Side effects of service-connected condition treatments

Frequently Asked Questions

Is IBS presumptive for Gulf War veterans?

Yes. If you served in Southwest Asia and have IBS that manifested by December 31, 2026, it's presumptively service-connected.

Can I claim IBS secondary to PTSD?

Yes. The gut-brain connection is well-established. Stress and PTSD significantly affect gut function.

What's the difference between 10% and 30%?

10% is for frequent episodes of bowel disturbance. 30% requires more constant abdominal distress with diarrhea or alternating symptoms.

Do I need a colonoscopy for IBS claim?

Not necessarily, but having tests that rule out other conditions (like inflammatory bowel disease) strengthens your diagnosis.
