Gastrointestinal conditions including gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), hiatal hernia, and other digestive disorders affect a significant number of veterans. These conditions often develop or worsen as a result of the stress of military service, medications prescribed for other service-connected conditions, or as secondary effects of conditions like PTSD. Understanding how the VA rates digestive conditions and the evidence needed to support your claim is essential for capturing the full impact these conditions have on your daily life.
GERD and hiatal hernia are rated together under Diagnostic Code 7346. At the 10% level, the VA requires two or more of the following symptoms of less severity than described for the 30% level: epigastric distress (pain or discomfort in the upper abdomen), dysphagia (difficulty swallowing), pyrosis (heartburn), and regurgitation. At the 30% level, the condition must cause persistently recurrent epigastric distress with dysphagia, pyrosis, and regurgitation accompanied by substernal or arm or shoulder pain, productive of considerable impairment of health. At the 60% level, the condition must cause symptoms of pain, vomiting, material weight loss and hematemesis or melena with moderate anemia, or other symptom combinations productive of severe impairment of health.
Irritable bowel syndrome is rated under Diagnostic Code 7319. A 0% rating is assigned for mild disturbances of bowel function with occasional episodes of abdominal distress. A 10% rating requires moderate disturbances with frequent episodes of bowel disturbance with abdominal distress. A 30% rating, the maximum for IBS, requires severe disturbances with diarrhea or alternating diarrhea and constipation with more or less constant abdominal distress. The distinction between these levels is primarily based on frequency and severity of symptoms and their impact on daily functioning.
Other digestive conditions that veterans commonly claim include peptic ulcer disease (DC 7304-7306), gastritis (DC 7304 per § 4.114 amendment which consolidated the former DC 7307), and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis (DC 7326 per § 4.114 amendment which consolidated the former DC 7323 ulcerative colitis framework into the unified Crohn's/IBD code). DC 7326 has a 4-tier schedule (10/30/60/100%) keyed to treatment regimen, daily diarrhea frequency, and systemic toxicity — biologic-agent therapy (Humira, Remicade, Stelara, Entyvio) marks the bright line between the 30% and 60% tiers. Peptic ulcers rate based on severity, recurrence frequency, and whether they cause anemia or weight loss. Diagnosis under DC 7326 requires endoscopy or radiologic confirmation per Note (2).
Secondary service connection is one of the most important pathways for GI claims. PTSD and other mental health conditions have a well-documented connection to gastrointestinal problems. The chronic stress response associated with PTSD affects the gut through the brain-gut axis, leading to increased acid production, altered gut motility, and changes in the gut microbiome. Research has shown that veterans with PTSD have significantly higher rates of GERD, IBS, peptic ulcer disease, and other GI conditions compared to veterans without PTSD.
Medications prescribed for other service-connected conditions are another common cause of GI problems. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen, commonly prescribed for musculoskeletal pain, are well known to cause or worsen GERD, gastritis, and peptic ulcers. Certain psychiatric medications can affect gut motility and cause constipation or diarrhea. If you developed GI symptoms after starting a medication for a service-connected condition, that medication use can form the basis of a secondary service connection claim.
The C&P exam for GI conditions evaluates the frequency and severity of your symptoms and their impact on your overall health. The examiner will ask about the specific symptoms you experience, how often they occur, what treatments you use, whether you have experienced weight loss, anemia, or nutritional deficiencies, and how the condition affects your ability to eat, work, and perform daily activities. Being specific about symptom frequency is important. Instead of saying "I have heartburn a lot," describe how many times per week you experience symptoms, how long episodes last, what triggers them, and what relief measures you use.
Weight loss is a significant factor in higher GI ratings. If your digestive condition has caused material weight loss, make sure your weight history is documented in your medical records. The VA defines "material weight loss" as a loss of more than 10% of baseline body weight sustained for three months or longer, or a body mass index (BMI) that drops below the healthy range due to the digestive condition. If you have experienced weight loss related to your GI condition, ensure your doctor documents the weight loss and its relationship to the digestive problem.
Anemia is another factor that can elevate your GI rating. Chronic GI conditions, particularly those involving bleeding such as peptic ulcers or inflammatory bowel disease, can lead to iron-deficiency anemia. Lab work showing low hemoglobin or low iron levels, combined with documentation of the GI source of the anemia, supports a higher rating. If you experience fatigue, weakness, or other symptoms of anemia, make sure your doctor orders blood work and documents the results.
When claiming a GI condition as secondary to PTSD or another mental health condition, a nexus letter from a physician who can explain the medical relationship between the psychological condition and the gastrointestinal symptoms significantly strengthens your claim. The letter should reference current medical literature supporting the brain-gut connection and explain why, in your specific case, the mental health condition caused or aggravated the GI condition.
Multiple GI conditions can complicate the rating process because the VA has rules against pyramiding, which prohibits rating the same symptoms under multiple diagnostic codes. If you have both GERD and IBS, the VA will typically rate them under the diagnostic code that produces the highest rating, not assign separate ratings for each. However, if the conditions produce distinct and separate symptoms, there may be grounds for separate ratings. Understanding how your symptoms map to specific diagnostic codes can help you present your claim in the most favorable light.
The Claim Recon Rating Calculator helps you model how GI condition ratings combine with your other service-connected disabilities. The C&P Exam Simulator walks you through the questions a GI examiner will ask about symptom frequency, severity, and functional impact. The Health Logger is especially useful for GI conditions because it allows you to track symptom episodes, food triggers, and the effect on daily activities over time. Ask Intel AI can help you navigate the complex web of GI diagnostic codes and determine which ones best apply to your symptoms. The Secondary Condition Finder identifies the strongest evidence pathways for claiming GI conditions as secondary to PTSD, medications, or other service-connected conditions.
