VA rating schedule, diagnostic code 7319
Irritable bowel syndrome (IBS) is a digestive condition the VA treats as a "functional" disorder, meaning it causes real, ongoing belly symptoms that are not explained by structural damage you can see on a scope or scan. The VA has a specific spot for it in its rating book at 38 CFR 4.114, under diagnostic code 7319, titled "Irritable bowel syndrome (IBS)." That code can also cover certain other functional digestive problems like dyspepsia, functional bloating, constipation, and diarrhea. To get service connection in the normal way, the rules generally look for a current diagnosis, an in-service event or illness, and a link ("nexus") between the two.
Under the current rules, IBS (DC 7319) is rated at three levels: 10%, 20%, or 30%, with 30% being the top schedular level for this code. What moves the rating up is how often you have abdominal pain related to having a bowel movement, plus other symptoms. The 30% level applies when there is abdominal pain related to defecation at least one day per week over the previous three months, along with two or more of these: a change in how often you go, a change in stool form, altered stool passage (straining and/or urgency), mucus in the stool (mucorrhea), abdominal bloating, or a feeling of distension. The 20% level uses the same symptom list but with pain on at least three days per month, and the 10% level uses pain at least once during the previous three months. So in general, more frequent pain tied to bowel movements, paired with those listed symptoms, points toward a higher percentage.
There is also a special exposure pathway. For Persian Gulf War veterans, the VA recognizes functional gastrointestinal disorders — which expressly include irritable bowel syndrome — as a "medically unexplained chronic multisymptom illness" under 38 CFR 3.317. For a qualifying veteran, this presumptive pathway can pay compensation when the condition became manifest during qualifying service or to a degree of 10 percent or more by December 31, 2026, without the veteran having to separately prove the usual nexus link. This is one way the rules can lift the burden of showing a direct connection for those who served in the Southwest Asia theater of operations. If a claim is denied, that is a starting point with appeal options, not the end of the road.

Across 10,158 real Board appeals for IBS & irritable bowel
A denial is often not the end either — remands (shown below) are sent back for more development and can still end in a grant. These are historical outcomes, not a prediction of your case.

Among the appeals that were granted or partly granted, the most common ways IBS & irritable bowel was linked to service:
In appeals where IBS & irritable bowel was the only condition decided and the Board granted it, the rating most often assigned was:
These appeals involved a recognized exposure — which can mean the link to service is presumed, with no nexus to prove:
The Veteran's service connection claims for lumbosacral strain, asthma, melasma and hydradenitis, hypertension, an acquired psychiatric disorder (claimed as depression, anxiety, and stress), left shoulder disorder, right shoulder disorder, left knee disorder, a left foot disorder, and IBS have been granted. The remaining issues are remanded.
The Veteran's claims for service connection for chronic fatigue syndrome, IBS with GERD, and OSA were denied. The claim for OSA was granted due to the receipt of new evidence showing a current disability.
The Veteran's service-connected disabilities, including PTSD, right knee meniscal tear, and IBS, have rendered him unable to secure or follow any substantially gainful employment from May 1, 2020 to May 1, 2021. The Board finds that the evidence is in balance, with all reasonable doubt resolved in favor of the Veteran.
The Veteran's deviated nasal septum was granted service connection. The claims for anxiety and sleep disturbance, erectile dysfunction, headaches, acid reflux, hypertension (high blood pressure), irritable bowel syndrome, and jaw condition were denied.
The Board has granted an initial 20 percent rating for service-connected vitamin D deficiency, finding that the Veteran's recurrent abdominal pain and diarrhea most closely approximates the criteria for a 20 percent rating under Diagnostic Code 6313. The claim for service connection for IBS was not addressed in this decision.
The appellant is granted a total disability rating based on individual unemployability (TDIU) and basic eligibility for Dependents' Educational Assistance (DEA) benefits, effective September 1, 2020.
