VA IBS Rating Guide: Mild, Moderate, Severe
IBS is rated under DC 7319 from 0% to 30% based on symptom frequency and severity. Here's exactly how each level is judged and the specific documentation that separates one rating from the next.
IBS is rated 0%, 10%, or 30% under DC 7319. The 30% rating requires severe symptoms — diarrhea, or alternating diarrhea and constipation — with more or less constant abdominal distress rather than intermittent flare-ups.
The VA rates irritable bowel syndrome under Diagnostic Code 7319. The difference between rating levels often hinges on a handful of specific findings that examiners check during the C&P exam. Knowing what each level requires lets you advocate for an accurate rating — and identify when an under-rating warrants an appeal.
Rating Criteria
0%
Mild — disturbances of bowel function with only occasional episodes of abdominal distress.
10%
Moderate — frequent episodes of bowel disturbance accompanied by abdominal distress.
30%
Severe — diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress rather than periodic flare-ups.
Evidence That Drives the Rating
- GI evaluation and colonoscopy, particularly useful for ruling out other structural causes
- A symptom log tracking frequency, duration, and severity of episodes over time
- Treatment records documenting ongoing management
- Records of dietary changes and medications tried, which help establish the chronic and treatment-resistant nature of the condition

Check Gulf War Presumptive ConditionsWhat to Expect at the C&P Exam
The examiner will complete the DBQ specific to irritable bowel syndrome. Bring symptom logs, treatment records, and a clear description of how the condition affects daily life and work. Describe your worst typical day, not your best day.
Why 'More or Less Constant' Is the Key Phrase
The jump from 10% to 30% specifically requires abdominal distress that's more or less constant, not just frequent flare-ups with symptom-free periods in between. A symptom log that clearly shows the pattern — near-daily distress versus periodic episodes — is more persuasive to a rater than a general description of 'bad IBS.'
The Gulf War Presumptive Shortcut
Gulf War-era veterans with chronic, unexplained GI symptoms may qualify for presumptive service connection without needing to prove a specific in-service cause — the undiagnosed illness and functional GI disorder categories cover exactly this kind of presentation. This path can significantly simplify the claim compared to standard direct service connection.
Common mistakes to avoid
- Reporting only good days to the C&P examiner instead of describing the full range of symptom severity.
- Not documenting the actual frequency of episodes, which is the single biggest factor separating the 10% and 30% levels.
