Irritable bowel syndrome is one of the most commonly claimed digestive conditions in the VA system, and it shows up in a veteran's records two ways: as a condition that began or was aggravated by military service, or as a secondary condition driven by a service-connected mental health condition. Either path can produce a compensable rating.
This page explains how the VA rates IBS in 2026, why the schedule caps it at 30%, and what you should file alongside it to move your combined rating.
How the VA Rates IBS - DC 7319
IBS is rated under 38 CFR 4.114, Diagnostic Code 7319. The criteria are entirely symptom driven - there is no lab value, endoscopy finding, or imaging requirement in the rating schedule. IBS is diagnosed clinically, which means colonoscopy and blood work are used to rule out other conditions, not to measure IBS itself.
| Rating | Criteria | 2026 pay |
|---|---|---|
| 30% | Severe symptoms: diarrhea, or more or less constant abdominal distress with constipation | $552.47 |
| 20% | Moderate symptoms: frequent episodes of bowel distress with some abdominal pain | $356.66 |
| 10% | Mild symptoms: occasional episodes of abdominal distress with frequent episodes of bowel dysfunction | $180.42 |
The difference between the tiers comes down to frequency and constancy. Occasional episodes of distress support 10%. Frequent episodes with regular pain support 20%. Diarrhea or abdominal distress that is more or less constant supports the 30% maximum.
The 30% Cap - and How to Work Around It
IBS tops out at 30% under DC 7319. There is no higher tier, no analogy path to a larger evaluation, and no way around it for IBS alone. Veterans who need more compensation from an IBS claim get it in one of two ways:
- Claim the companion conditions. IBS rarely travels alone. Anxiety, GERD, and migraines are all separately ratable and frequently caused or aggravated by IBS and by the same underlying service-connected condition.
- Check TDIU eligibility. If severe bowel symptoms force frequent bathroom trips and keep you from holding steady work, you may qualify for Total Disability based on Individual Unemployability, which pays at the 100% rate even when your schedular combined rating is below 100%.
IBS Is a PACT Act Presumptive Condition
The Sergeant First Class Heath Robinson Honoring our PACT Act of 2022 made functional gastrointestinal disorders, including IBS, presumptive for veterans who served in covered locations - the Gulf War theater and the post-9/11 burn pit locations including Iraq, Afghanistan, Kuwait, Qatar, Saudi Arabia, Syria, Djibouti, Somalia, Egypt, Jordan, Lebanon, Yemen, and Uzbekistan during the covered periods.
Under a presumption you do not have to prove a nexus between your service or burn pit exposure and the IBS. You need qualifying service in a covered location and a current diagnosis. If your IBS claim was denied before the PACT Act passed, file a supplemental claim: pre-PACT denials can be readjudicated.
See the full PACT Act presumptive conditions list.
IBS Secondary to PTSD and Anxiety
The most common way veterans get IBS rated is as a secondary condition under 38 CFR 3.310. The gut-brain connection is well documented: chronic stress and anxiety from PTSD measurably worsen gastrointestinal function, and medication prescribed for mental health conditions can cause or aggravate bowel symptoms.
A secondary claim needs three things: a current IBS diagnosis, an already service-connected primary condition such as PTSD, anxiety, or depression, and a nexus opinion from a physician stating it is at least as likely as not that the primary condition caused or aggravated the IBS. You do not have to prove the IBS began in service.
Note that IBS is a physical condition rated under the digestive formula. It does not merge into your mental health rating the way PTSD and depression do, so it combines on top of your mental health rating under the standard VA math. A 70% mental health rating plus 30% IBS combines to 79%, which rounds to 80%.
Evidence That Moves Your Rating Up
Because the criteria are symptom driven, the evidence that wins a higher tier is a record of frequency and constancy, not test results:
- A symptom log recording daily bowel function, abdominal pain, and missed work or activities.
- Treatment records showing ongoing GI care, prescription antispasmodics, antidiarrheals, or diet management.
- Work impact documentation: absences, FMLA paperwork, accommodations for bathroom access.
- A diagnosis that names IBS specifically, supported by ruled-out alternatives such as celiac disease or inflammatory bowel disease.
At your C&P exam, describe your worst week, not your best day. Say how many days per week you have symptoms, whether the distress is constant or episodic, and what you cannot do because of it. The 30% tier turns on the words frequent, severe, and more or less constant.
Conditions to Claim Alongside IBS
- GERD. Frequently co-occurring with IBS and rated separately under DC 7206. GERD VA rating guide.
- Anxiety and depression. Rated under the mental health formula and commonly primary to IBS or aggravated by it. Depression VA rating guide.
- Migraines. Rated up to 50% under DC 8100 and commonly connected to the same mental health condition driving IBS. Migraine VA rating guide.
