IBS VA Rating and Diagnostic Code 7319 Criteria

Detailed breakdown of each IBS rating tier and symptom requirement

Because all three compensable tiers under Diagnostic Code 7319 use the same list of six bowel symptoms, the difference between a 10%, 20%, and 30% evaluation depends on how frequently you experience abdominal pain related to defecation during the three-month window preceding your examination.

0 percent noncompensable rating (38 CFR 4.31)

Although the May 19, 2024 revision removed the explicit 0% row from Diagnostic Code 7319, 38 CFR 4.31 directs the VA to assign a 0% rating whenever a diagnostic code lacks a zero percent tier and compensable requirements are not met.

A 0% evaluation applies when a veteran establishes direct or secondary service connection for IBS, but had no defecation-related abdominal pain during the previous three months or fewer than two of the six bowel symptoms. While a 0% rating pays no monthly cash benefit, it establishes service connection, qualifies the veteran for no-cost VA health care and medications for IBS, and allows a claim for an increased rating if symptoms worsen. (A 0% evaluation cannot establish presumptive service connection under 38 CFR 3.317, which requires manifestation to 10% or more.)

10 percent disability rating

A 10% evaluation requires abdominal pain related to defecation at least once during the previous three months, accompanied by two or more of the six qualifying bowel symptoms. Effective 2025-12-01, a standalone 10% rating pays $180.42 per month for a veteran with no dependents.

20 percent disability rating

Added on May 19, 2024 to bridge the gap between 10% and 30%, the 20% evaluation requires abdominal pain related to defecation for at least three days per month during the previous three months, plus two or more of the six qualifying bowel symptoms. A standalone 20% rating pays $356.66 per month for a veteran without dependents.

30 percent disability rating (schedular maximum)

The maximum schedular evaluation under Diagnostic Code 7319 is 30%, requiring abdominal pain related to defecation at least one day per week during the previous three months, plus two or more of the six qualifying bowel symptoms. Effective 2025-12-01, a standalone 30% rating pays $552.47 per month for a veteran alone, and veterans rated at 30% or higher qualify for additional allowances for eligible dependents. At 89 FR 19738, the VA confirmed that 30% is the maximum schedular rating for IBS, reserving extraschedular consideration under 38 CFR 3.321(b)(1) or Total Disability based on Individual Unemployability (TDIU) under 38 CFR 4.16 for exceptional cases.

How the VA evaluates the six bowel symptoms and the Bristol Stool Scale

Every compensable tier under Diagnostic Code 7319 requires at least two of the following six symptoms alongside defecation-related abdominal pain:

1. Change in stool frequency: Increased daily bowel movements (IBS-D), decreased weekly bowel movements (IBS-C), or alternating episodes of both (IBS-M).
2. Change in stool form: Alterations in consistency or appearance, such as hard pellets or watery stools. At 89 FR 19738, the VA confirmed that adjudicators accept provider findings recorded using the Bristol Stool Scale (Meyers Scale, Types 1 through 7) to document changes in stool form and frequency.
3. Altered stool passage (straining and/or urgency): Straining to pass stool, incomplete evacuation, or sudden urgency requiring immediate restroom access.
4. Mucorrhea: Passing visible mucus in the stool.
5. Abdominal bloating: A subjective feeling of trapped gas, fullness, or internal abdominal pressure.
6. Subjective distension: Perceived or visible outward abdominal swelling during flare-ups.

Because “(5) abdominal bloating, or (6) subjective distension” are listed as separate items in DC 7319, meeting any two of the six items satisfies the symptom count requirement.

Mandatory note to Diagnostic Code 7319 and anti-pyramiding rules

Diagnostic Code 7319 includes a binding note in 38 CFR 4.114:

• Note to DC 7319: “This diagnostic code may include functional digestive disorders (see § 3.317 of this chapter), such as dyspepsia, functional bloating and constipation, and diarrhea. Evaluate other symptoms of a functional digestive disorder not encompassed by this diagnostic code under the appropriate diagnostic code, to include gastrointestinal dysmotility syndrome (DC 7356), following the general principles of § 4.14 and this section.”

Related intestinal codes and anti-pyramiding rules

Under revised 38 CFR 4.114 and 38 CFR 4.14:

• Related codes: Diagnostic Code 7325 (Enteritis, chronic) is rated as IBS (DC 7319) or Crohn’s disease (DC 7326) based on the predominant disability. Diagnostic Code 7356 (Gastrointestinal dysmotility syndrome) is rated at 10%, 30%, 50%, or 80% for functional GI illnesses under 38 CFR 3.317(a)(2)(i)(B)(3) other than those evaluated under DC 7319. Structural inflammatory bowel diseases—DC 7326 (Crohn’s disease) and DC 7323 (Colitis, ulcerative)—require endoscopic or radiologic confirmation (Note 2 to DC 7326) and are rated at 10%, 30%, 60%, or 100%.
• Codes that CANNOT combine with DC 7319: Under 38 CFR 4.114, ratings under Diagnostic Codes 7301 through 7329 inclusive, 7331, 7342, 7345 through 7350 inclusive, 7352, and 7355 through 7357 inclusive cannot be combined. Instead, the VA assigns a single evaluation under the code reflecting the predominant disability picture, elevated to the next higher level if warranted by overall severity.
• Codes that CAN combine with DC 7319: The 38 CFR 4.114 bar does not include 7200-series esophageal codes or 7332–7337 anorectal codes. As confirmed at 89 FR 19738, a veteran may receive separate ratings for IBS (DC 7319) and GERD (DC 7206) or Barrett’s esophagus (DC 7207), or for DC 7332 (Rectum and anus, impairment of sphincter control) (0%–100%) and DC 7336 (Hemorrhoids, external or internal) (10% or 20%), when distinct symptoms exist.

The May 19, 2024 schedule revision and grandfathering protections

Before May 19, 2024, Diagnostic Code 7319 (Irritable colon syndrome) had three tiers: 30% (severe; diarrhea, or alternating diarrhea and constipation, with more or less constant abdominal distress), 10% (moderate; frequent episodes of bowel disturbance with abdominal distress), and 0% (mild; disturbances of bowel function with occasional episodes of abdominal distress).

Under 38 U.S.C. 1155 and 38 CFR 3.951(a), a rating schedule revision cannot be used to reduce an evaluation in effect on the date of the revision unless medical evidence shows actual improvement under ordinary conditions of life. Veterans rated at 10% or 30% before May 19, 2024 retain their protected rating, and veterans rated at 0% or 10% may file for an increase to 20% or 30% if their symptoms meet the current frequency criteria.

Three pathways to service connection for IBS

1. Presumptive service connection for Gulf War veterans (38 CFR 3.317)

Under 38 CFR 3.317(a)(2)(i)(B)(3), the VA presumes service connection for functional gastrointestinal disorders (excluding structural gastrointestinal diseases)—including irritable bowel syndrome—as a medically unexplained chronic multisymptom illness (MUCMI). Qualifying requires:

1. Qualifying service: Service under 38 CFR 3.317(e) in the Southwest Asia theater of operations during the Persian Gulf War (Iraq, Kuwait, Saudi Arabia, the neutral zone between Iraq and Saudi Arabia, Bahrain, Qatar, the United Arab Emirates, Oman, the Gulf of Aden, the Gulf of Oman, the Persian Gulf, the Arabian Sea, the Red Sea, and airspace above them, plus 38 U.S.C. 1117 locations including Afghanistan, Israel, Egypt, Turkey, Syria, and Jordan).
2. Chronicity: Persistence for 6 months or more under 38 CFR 3.317(a)(4).
3. Compensable manifestation: Under 38 CFR 3.317(a)(1)(i), the disability must have become manifest either during active service in the Southwest Asia theater of operations or “to a degree of 10 percent or more not later than December 31, 2026.” Check the current text of the regulation for any change to that date.

2. Direct service connection (38 CFR 3.303)

Under 38 CFR 3.303, direct service connection requires a current IBS diagnosis, evidence of in-service gastrointestinal illness or chronic bowel symptoms in service medical records, and a medical nexus linking current IBS to active service.

3. Secondary service connection (38 CFR 3.310)

Under 38 CFR 3.310(a), a disability proximately due to or aggravated by an existing service-connected condition may receive secondary service connection:

• PTSD, depression, and anxiety: Autonomic nervous system dysregulation along the gut-brain axis associated with service-connected PTSD, depressive disorders, or anxiety disorders may cause or aggravate IBS when supported by a medical nexus opinion.
• Medication side effects: Daily nonsteroidal anti-inflammatory drugs (NSAIDs), analgesics, antibiotics, or psychiatric medications prescribed for service-connected conditions such as back pain may alter gut motility and flora, causing or aggravating chronic bowel symptoms.

How the C&P exam and Intestinal Conditions DBQ measure IBS

At a Compensation and Pension (C&P) examination, the clinician completes the Intestinal Conditions Disability Benefits Questionnaire (DBQ) (verified on the VA Public DBQs page). The examiner reviews your records and interviews you to document:

1. Confirmed IBS diagnosis: Verification of your IBS diagnosis and prior colonoscopy, endoscopy, or lab studies ruling out structural disease.
2. Abdominal pain frequency over the previous three months: Whether defecation-related abdominal pain occurred none, at least once (10%), at least three days per month (20%), or at least one day per week (30%).
3. Accompanying bowel symptoms: Which of the six DC 7319 symptoms are present—change in stool frequency, change in stool form (referencing the Bristol Stool Scale), altered stool passage (straining and/or urgency), mucorrhea, abdominal bloating, and subjective distension.
4. Medications and complications: Prescribed treatments, dietary modifications, and whether separate complications such as sphincter control impairment (DC 7332) or hemorrhoids (DC 7336) exist.

Bringing a dated three-month symptom log tracking pain days, stool frequency, Bristol Stool Scale form, urgency, straining, mucus, and bloating helps you report accurate frequencies during the DBQ interview.
