IBS is rated under Diagnostic Code 7319 in 38 CFR § 4.114. VA changed these criteria effective May 19, 2024. The current schedule looks at abdominal pain related to defecation (having a bowel movement) and specified associated symptoms.
The useful question is whether the medical findings and your actual symptom history address each requirement. A diagnosis alone does not establish the percentage. Neither does the number of trips to the bathroom by itself.
This page covers the IBS rating chart, the 2024 changes, how to prove IBS is service connected (direct, secondary to PTSD, and the Gulf War presumption), the C&P exam, IBS with GERD and other digestive ratings, and why VA denies IBS claims.
IBS VA rating criteria (DC 7319)
Every tier below requires two or more of these associated symptoms.
- A change in stool frequency.
- A change in stool form.
- Altered stool passage, including straining or urgency.
- Mucus in the stool (mucorrhea).
- Abdominal bloating.
- Subjective distension, meaning a reported feeling of abdominal swelling or expansion.
| Rating | Abdominal pain related to defecation |
|---|---|
| 10% | At least once during the previous three months, plus two or more listed symptoms |
| 20% | At least three days per month during the previous three months, plus two or more listed symptoms |
| 30% | At least one day per week during the previous three months, plus two or more listed symptoms |
The frequency requirements refer to the pain associated with defecation. Describing diarrhea as “frequent” without explaining the pain pattern and associated symptoms can leave important parts of the criteria unanswered. A note to DC 7319 says the code may also cover other functional digestive disorders, such as dyspepsia, functional bloating and constipation, and diarrhea; symptoms the code does not cover are rated under another code. The current DC 7319 reference provides the schedule alongside this guide.
New VA IBS rating criteria: what changed in May 2024
The 2024 digestive-system final rule replaced the former severity labels with the current pain-frequency criteria and added the 20% tier. The effective date was May 19, 2024.
Older decisions and guides may discuss “mild,” “moderate,” or “severe” IBS and constant abdominal distress. Those descriptions concern the former criteria, rather than the current frequency requirements in the table above. They should not be used as a shortcut for today's 10%, 20%, or 30% evaluation.
If an appeal involves rating periods before and after the amendment, the applicable version and effective-date rules need separate review. This page explains the current criteria; it does not determine which version governs every period in an individual appeal.
How to prove IBS for VA disability
Every IBS claim needs a current diagnosis. After that, the evidence depends on the theory you claim under.
Direct service connection
Direct service connection needs evidence of the current condition, what happened in service, and a medical link between them. Service treatment records showing stomach or bowel complaints, sick call visits for diarrhea or abdominal pain, and your own account of when the symptoms started all help show the in-service part.
IBS secondary to PTSD or another service-connected condition
Under 38 CFR § 3.310, IBS can be service connected if an already service-connected condition caused it, or aggravated it, meaning the IBS would be less severe but for that condition. Having both conditions is not by itself proof of that relationship. PTSD is the most common cause veterans claim for IBS at the Board, and a 2024 study of VA patient records found PTSD and IBS correlated in veterans who served during wartime. A correlation across a database is not proof for one veteran, so the claim still needs a medical opinion that explains how your PTSD caused or worsened your IBS and addresses aggravation, not only causation. Do not assume that a mental-health diagnosis or medication automatically supplies the medical connection in an individual case. The IBS secondary to PTSD page covers that claim in full, with the Board's results, and the secondary conditions to PTSD page lists the other conditions veterans claim from PTSD.
Gulf War veterans: IBS as a functional gastrointestinal disorder
The Gulf War law, 38 USC § 1117, names irritable bowel syndrome as a medically unexplained chronic multisymptom illness. Since the PACT Act amended it in 2022, a Persian Gulf veteran can be compensated for one that became manifest to any degree at any time, with no medical opinion linking it to service, and "Persian Gulf veteran" now covers service during the Persian Gulf War in the Southwest Asia theater of operations, Afghanistan, Israel, Egypt, Turkey, Syria or Jordan. VA's regulation, 38 CFR § 3.317, has not been rewritten to match and still prints the older limits (a 10 percent level by December 31, 2026, and the Southwest Asia list alone); the amended statute no longer has them. The regulation's other terms still describe how VA applies the rule: IBS is a functional gastrointestinal disorder, structural gastrointestinal diseases are excluded, the condition has to be chronic (six months or more), and VA can deny the claim if there is affirmative evidence of another cause. See the Gulf War illness guide and VA's Gulf War illness guidance.
The IBS C&P exam and symptom log
What to tell the examiner
Explain when the symptoms began, their relationship to bowel movements, the actual frequency over the previous three months, and which associated symptoms occur. Bring relevant treatment records and a medication list. Describe both typical days and flares without making either stand in for the entire period.
A clinician determines the diagnosis and whether other conditions need evaluation. Testing depends on the clinical situation; this guide does not mean every veteran must obtain a colonoscopy or a specialist letter before filing. Do not change treatment to affect the appearance of symptoms at an examination.
What an IBS symptom log should include
A log can make a symptom history easier to understand. It does not replace diagnosis, examination findings, or other required evidence. Record what actually happens, including better days and flares.
| Detail | What to record |
|---|---|
| Date and pain | Whether abdominal pain occurred and how it related to a bowel movement |
| Frequency | The days with that pain, so the pattern over the previous three months is clear |
| Associated symptoms | Changes in stool frequency or form, urgency or straining, mucus, bloating, or a feeling of distension |
| Daily effects | Actual interruptions to work, travel, sleep, or other activities |
| Treatment | Relevant visits, prescribed treatment, and the response you observed |
| Uncertainty | Whether an entry is contemporaneous or a later recollection; label estimates honestly |
Fictional example: a veteran records defecation-related pain on specific dates, urgency, and a change in stool form. That supplies more useful detail than “bad stomach most days.” The examiner and VA still need to assess the complete record; the example is not a predicted rating.
Do not turn a recent recollection into a diary that appears to have been kept months earlier. If you have no log, explain what you remember and identify records that may help establish the pattern.
IBS with GERD and other digestive ratings
Separate digestive diagnoses do not automatically produce separate ratings. Section 4.114 bars combining ratings under DCs 7301 through 7329, 7331, 7342, 7345 through 7350, 7352, and 7355 through 7357 with each other. IBS (DC 7319) is on that list, so IBS and another condition on it, such as ulcerative colitis, get one rating under the code that reflects the main disability, raised one level if the overall picture is more severe.
GERD is rated under DC 7206 and hemorrhoids under DC 7336. Neither code is on that list, so either can be rated separately from IBS. The limit that still applies is 38 CFR § 4.14: VA cannot rate the same symptom twice under two diagnoses. Do not assume that adding IBS, GERD, and another digestive diagnosis yields a particular combined rating.
Other service-connected disabilities and, where the requirements are met, individual unemployability are separate questions. If service-connected disabilities prevent substantially gainful employment, review VA's individual unemployability information. IBS severity alone does not establish eligibility or a particular outcome.
Why VA denies IBS claims
IBS claims do a little better at the Board than the average claim. Across 6,556 decided Board rulings on IBS from 2021 to 2026, 31.1% were granted, 28.2% denied and 40.7% remanded. That grant rate is 6.4 points above the Board-wide 24.7 percent.
When the Board denies IBS service connection, the most common reason is not the link to service. It is that the record does not show a current diagnosed disability. The patterns behind that, and behind the other denials, repeat.
No current diagnosis. Records describe stomach trouble, diarrhea or cramping, but no clinician diagnosed IBS or another digestive disorder. Symptoms alone are not a disability VA can rate.
Symptoms tied to something else. An examiner attributes the symptoms to a structural disease, an infection that resolved, a medication, or diet. For a Gulf War claim, a known structural cause takes the claim out of § 3.317.
Nothing in service. Service records are silent, and the first complaint comes years after discharge with no account of what happened in between.
A secondary opinion that skips aggravation. For IBS claimed secondary to PTSD or another condition, an opinion that says only "not caused by" without addressing whether the condition made the IBS worse is incomplete.
When the Board sends an IBS claim back instead of deciding it, the most common reason is an inadequate VA exam or opinion. The Board section below shows how often each denial and remand reason came up, and how claims argued as direct, secondary and presumptive have fared.
Before you ask VA to review your IBS rating
Compare the decision's reasons with the applicable rating period and the evidence VA considered. Identify whether the disagreement concerns service connection, the symptom findings, the criteria applied, or the effective date. Those are different issues and may need different evidence or review options.
A useful next step is to put the decision, relevant medical findings, and an honest symptom history together. An accredited representative can help assess the available review route and deadlines. This guide explains the schedule; it does not promise an increase.
Questions veterans ask about IBS
What is the highest VA rating for IBS?
30 percent, for abdominal pain related to bowel movements at least one day per week over the previous three months plus two or more listed symptoms. A higher combined rating has to come from other conditions.
Can IBS be rated at 0 percent?
Yes. DC 7319 no longer lists a 0 percent tier, but 38 CFR § 4.31 assigns 0 percent whenever a code has no zero tier and the 10 percent requirements are not met. A 0 percent rating still means IBS is service connected, which is different from a denial.
Can you get a VA rating for IBS and GERD?
Yes. GERD is rated under DC 7206, which is outside the group of digestive codes § 4.114 bars from combining with IBS, so each can be rated. VA still cannot count the same symptom under both.
Is IBS a presumptive condition for VA?
For Gulf War veterans, yes. 38 USC § 1117 names IBS as a chronic multisymptom illness, and since the PACT Act it counts if it appeared to any degree at any time, for veterans who served in the Southwest Asia theater, Afghanistan, Israel, Egypt, Turkey, Syria or Jordan during the Persian Gulf War. Other veterans have to prove IBS directly or as a secondary condition.
Can IBS be secondary to PTSD?
Yes. IBS can be service connected secondary to PTSD if a medical opinion explains how PTSD caused it or made it worse. The Board section below shows how IBS claimed secondary to PTSD has fared.
Sources and limits
The current tiers are drawn from § 4.114 and the 2024 final rule (89 FR 19735, effective May 19, 2024). The separate zero-percent rule is in § 4.31, secondary service connection in § 3.310, the Gulf War presumption in 38 USC § 1117 as amended by the PACT Act (Pub. L. 117-168, § 405) and in § 3.317, which has not yet been updated to match, and the rule against rating the same symptom twice in § 4.14. The PTSD and IBS correlation is from Kent, "The relationship between post-traumatic stress disorder and gastrointestinal disease in United States Military Veterans," SAGE Open Medicine (2024), a study of VA patient records. Board figures come from Claim Raven's read of 511,036 Board decisions from 2021 to 2026, which contain 1,378,030 rulings; dismissed, withdrawn and moot rulings are excluded from the shares. Board decisions from earlier periods can illustrate an individual dispute, but they do not replace the current regulation or predict another veteran's result.
