Irritable bowel syndrome (IBS)
- IBS is rated under 38 CFR 4.114, Diagnostic Code 7319, with a maximum schedular evaluation of 30 percent for severe, nearly constant symptoms.
- For veterans with qualifying Southwest Asia service, IBS is a presumptive "medically unexplained chronic multisymptom illness" under 38 CFR 3.317, so a specific in-service event is not always required.
- IBS is commonly filed as secondary to a service-connected mental health condition (PTSD, anxiety, depression) under 38 CFR 3.310 through the documented gut-brain pathway.
- Under 38 CFR 4.113, digestive conditions with overlapping symptoms are evaluated together rather than stacked, so a higher single evaluation may apply rather than separate ratings for each GI diagnosis.

Overview
Irritable bowel syndrome is one of the more commonly service-connected digestive conditions. The VA evaluates IBS under 38 CFR 4.114, Diagnostic Code 7319 (irritable colon syndrome). Under 38 CFR 4.113, digestive-system conditions that produce a common disability picture cannot be rated separately if doing so would compensate the same underlying symptoms twice, so a veteran diagnosed with IBS alongside other digestive conditions may receive a single, higher evaluation rather than stacked ratings.
For veterans who served in the Southwest Asia theater, IBS is recognized under 38 CFR 3.317 as a "medically unexplained chronic multisymptom illness" presumptive for Gulf War veterans. That means a qualifying Gulf War veteran with a current IBS diagnosis may not need to prove a specific in-service event if the condition manifested to a compensable degree during the presumptive period. Veterans who suspect exposure-related digestive illness can also review the PACT Act and burn-pit resources at /benefits/disability/pact-act and /benefits/disability/burn-pits.
IBS is frequently claimed alongside, or as secondary to, service-connected anxiety, PTSD, or depression. The gut-brain connection is well documented in medical literature, and if the VA has rated a veteran for a qualifying mental health condition, a nexus opinion linking IBS to that primary condition under 38 CFR 3.310 may support secondary service connection. See /benefits/disability/secondary-conditions for the broader secondary-claim workflow.
Evidence expectations for IBS focus on a documented diagnosis from a GI specialist, medical records that establish symptom frequency and severity, and functional-impact evidence that speaks to how symptoms affect work and daily activities. The VA evaluates IBS based on the severity and persistence of abdominal symptoms; it does not rate IBS based on laboratory findings, since IBS is diagnosed clinically.
Rating Criteria
| Rating | Criteria |
|---|---|
| 0% | A diagnosis of irritable bowel syndrome has been established, but the documented symptoms are mild or asymptomatic and do not interfere with daily functioning. |
| 10% | Moderate symptoms: frequent episodes of bowel disturbance with abdominal distress, documented in the medical record as ongoing but not severe or constant. |
| 30% | Severe symptoms: diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress. This is the maximum schedular rating under DC 7319. |
- 0%
A diagnosis of irritable bowel syndrome has been established, but the documented symptoms are mild or asymptomatic and do not interfere with daily functioning.
- 10%
Moderate symptoms: frequent episodes of bowel disturbance with abdominal distress, documented in the medical record as ongoing but not severe or constant.
- 30%
Severe symptoms: diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress. This is the maximum schedular rating under DC 7319.
These criteria describe how a VA Compensation & Pension examiner evaluates the condition during a rating exam. They are not a self-test. For mental health conditions under 38 CFR 4.130, a diagnosis must be made by a qualified clinician under DSM-5. Actual ratings depend on the totality of evidence reviewed by the VA.
Evidence Checklist
Required
Current diagnosis from a GI specialist
A current diagnosis of IBS from a gastroenterologist or qualified provider, with documentation of the Rome criteria or clinical findings used to reach the diagnosis.
Medical records documenting symptom frequency and severity
Treatment notes, specialist records, and any diagnostic workup (imaging, colonoscopy) that rule out other conditions and establish the pattern of IBS symptoms over time. Under 38 CFR 4.114, severity is the key rating factor.
Recommended
Service treatment records or Gulf War service documentation
For veterans claiming the 38 CFR 3.317 Gulf War presumption, documentation of qualifying Southwest Asia service is essential. For direct service connection, in-service records showing onset of GI symptoms during service support the claim.
Nexus opinion for secondary claims
If a veteran is filing IBS as secondary to a service-connected mental health condition (PTSD, anxiety, depression) under 38 CFR 3.310, a medical opinion explaining the gut-brain pathway strengthens the claim.
Buddy statements about functional impact
Statements from family, coworkers, or fellow service members describing observed symptom frequency, missed work, and avoided activities due to unpredictable flares.
Helpful
Symptom diary
A personal log of flare frequency, severity, triggers, and functional impact over several months. Concrete examples carry more weight than general descriptions at the C&P exam.
C&P exam preparation
Before the Compensation and Pension exam, review the DC 7319 criteria so the examiner can document the frequency of bowel disturbance and the persistence of abdominal distress in concrete terms.
Secondary Conditions
These conditions may be claimed as secondary to Irritable Bowel Syndrome (IBS). A nexus is the medical link between a service-connected condition and a related condition. Nexus strength indicates the level of established medical evidence supporting that connection.
Anxiety / Depression
DC 9413, Typical range: 10%, 30%, 50%, 70%
Weight loss / nutritional deficiency
DC 7319, Typical range: 10%, 30%
Sleep disturbance
DC 6847, Typical range: 0%, 30%, 50%
