The IBS DBQ is short. The entire rating hinges on three words the examiner must check: mild, moderate, or severe. Those words map directly to the 0/10/30 schedule under 38 CFR § 4.114, Diagnostic Code 7319. Get the frequency of bowel disturbance and whether abdominal distress is “more or less constant” on the record and the tier follows.
What the examiner is filling out
The Irritable Bowel Syndrome DBQ asks the examiner to record:
- Diagnosis — IBS or other functional gastrointestinal disorder.
- Symptoms — diarrhea, constipation, alternating bowel habits, abdominal pain or cramping, bloating, urgency.
- Frequency and severity — how often episodes occur and whether abdominal distress is constant.
- Impact on daily activities and work — missed work, dietary restrictions, medication use.
The DC 7319 schedule
Diagnosed IBS with infrequent or mild symptoms that do not cause significant bowel disturbance.
Episodes occur often enough to be considered frequent, with recurring abdominal distress. This is the most common rating for veterans with documented ongoing symptoms.
The maximum schedular rating. Requires either chronic diarrhea or alternating patterns plus abdominal distress that is present most of the time, not just during flare-ups.
The phrases that map to each tier
Magic words for this tier
To establish moderate (10%):
- “I have bowel urgency or diarrhea several times a week.”
- “Cramping and abdominal distress happen with most episodes.”
- “I have to plan my day around bathroom access.”
Magic words for this tier
To establish severe (30%):
- “I have diarrhea or alternating diarrhea and constipation nearly every day.”
- “Abdominal pain or cramping is present most of the time, not just during flares.”
- “I have missed work or left early [X] times per month due to symptoms.”
Evidence that wins
Bring a symptom log showing dates, stool type (Bristol scale if you use it), urgency, and whether you had to stop activity. Pair it with pharmacy records for antispasmodics, fiber, or prescription IBS meds. A buddy statement describing visible distress or frequent bathroom trips helps. Treatment notes that use the words “frequent” or “constant abdominal distress” are gold.
What NOT to say
What NOT to say
- “It only happens when I eat certain foods.” (Sounds controllable and mild.)
- “I just deal with it.” (Undersells frequency and distress.)
- “It comes and goes.” (Vague — quantify how often.)
- “I haven’t missed work because of it.” (Kills the 30% economic impact angle.)
- “It’s mostly constipation.” (30% requires diarrhea or alternating pattern plus constant distress.)
Medication and diet history
List every medication, supplement, and dietary change you have tried. Ongoing symptoms despite treatment supports the higher severity language.
