Gastroenterology
Gastroenterology claims cover the digestive tract and its supporting organs: GERD, IBS, Crohn's disease, ulcerative colitis, peptic ulcers, diverticular disease, hemorrhoids, and the gallbladder and liver conditions that follow.
Digestive conditions are the most commonly filed secondary claims in the VA system, and the ones most reshaped by recent regulation. Two problems run through almost every file. The first is the mechanism: a service-connected condition exists, a digestive diagnosis exists, and nothing in the record explains how one produced the other. The second is the schedule itself: the VA rewrote the digestive rating criteria effective May 19, 2024, and evidence built for the old criteria can miss what the new ones actually measure. Our licensed clinicians prepare nexus letters and independent medical opinions for direct, secondary, and aggravation claims, and we write the pharmacological or physiological mechanism out in full rather than asserting it in a sentence.
About Gastroenterology Claims
Gastroenterology claims cover the digestive tract and its supporting organs: GERD, IBS, inflammatory bowel disease, peptic ulcers, diverticular disease, hemorrhoids, and gallbladder and liver conditions. Most begin the same way. Not with a sick call entry, but with a prescription. An SSRI for service-connected PTSD. Years of NSAIDs for a service-connected knee. The digestive symptoms arrive later, sometimes much later, and the service treatment records say nothing about them at all.
That fact pattern is why secondary service connection dominates this body system, and why the nexus opinion carries so much of the weight. The diagnosis is rarely in dispute. The question the rater needs answered is why a condition that appeared years after separation belongs to service, and the answer runs through pharmacology and physiology: SSRIs and SNRIs increasing gastric acid production and relaxing the lower esophageal sphincter, NSAIDs stripping the prostaglandins that protect the stomach lining, chronic stress altering gut motility and permeability through the gut-brain axis. Each of those mechanisms is documented in the medical literature. None of them helps a claim unless a clinician writes it down.
These conditions are rated under 38 CFR 4.114, and the schedule was rewritten effective May 19, 2024. GERD, long rated by analogy to hiatal hernia under DC 7346 at 10, 30, or 60 percent, received its own code, DC 7206, rated at 0, 10, 30, 50, or 80 percent on esophageal stricture criteria. IBS under DC 7319 gained a compensable floor and a 20 percent tier. Which version governs a claim depends on when it was filed, and claims pending on the effective date are evaluated under whichever version is more favorable. Evidence built for one set of criteria can be nearly silent on what the other one measures.
One more rule shapes this body system in a way most veterans never hear about. Under 38 CFR 4.114, ratings under a specified range of digestive diagnostic codes are not combined with each other. A single evaluation is assigned under the code reflecting the predominant disability picture, with elevation to the next higher level where the overall severity warrants it. Whether two digestive conditions produce one rating or two depends on which codes they fall under and which version of the schedule applies, which makes accurate coding and thorough severity documentation worth real money.
While no medical opinion can guarantee a specific VA outcome, clear, credible, and well-documented evidence gives a claim its strongest foundation. Our role is the medicine and the documentation. The decision on the claim rests with the VA.

Common Gastroenterology Service-Connection Pathways
Many gastroenterology claims succeed not as standalone conditions, but as part of a chain — one diagnosis medically explaining another. These are the relationships we most often document in plain medical terms.
SSRIs and SNRIs prescribed for service-connected mental health conditions can increase gastric acid production and reduce lower esophageal sphincter tone. Pharmacy records dating the prescription before the reflux make this argument concrete.
Sustained stress from a service-connected condition alters gut motility, increases intestinal permeability, and disrupts the microbiome through the gut-brain axis. The mechanism is well described in the literature and almost never written into the file.
Years of prescribed anti-inflammatory therapy for a service-connected joint inhibit the protective prostaglandins that maintain the stomach lining. This is the same medication chain your musculoskeletal rating already documents from the other end.
The gut-brain-immune axis links chronic stress to immune dysregulation and intestinal inflammation that can trigger or worsen Crohn's disease and ulcerative colitis. These opinions must address causation and aggravation separately.
IBS and other functional gastrointestinal disorders are presumptive under 38 CFR 3.317 for qualifying Gulf War service, removing the causation burden entirely. Severity documentation still decides the rating.
Chronic straining and altered bowel patterns produce venous engorgement over time. Hemorrhoids secondary to a service-connected bowel condition or to constipating medications are documentable and routinely left unfiled.
Nocturnal reflux and microaspiration can aggravate airway disease and fragment sleep. The chain runs outward from a digestive condition into the respiratory and rating picture.
Unpredictable symptoms, dietary restriction, and social limitation are well-described contributors to mood disorders. These opinions require a psychiatrist or doctoral-level psychologist.
Why Gastroenterology Claims Can Be Challenging
Understanding these challenges in advance is the first step toward building a clearer medical record — and knowing where additional evidence may help.
A Rating Schedule That Just Changed
The digestive criteria were rewritten effective May 19, 2024. GERD moved from symptom-based criteria under DC 7346 to stricture-based criteria under DC 7206. Evidence assembled for one version can be silent on what the other measures, and pending claims get whichever is more favorable.
The Single Evaluation Rule
Ratings under a specified range of digestive codes are not combined. One evaluation is assigned under the predominant disability, with possible elevation. Which codes your conditions fall under, and which schedule version applies, decides whether you carry one rating or two.
The Symptom Log Nobody Kept
Digestive ratings turn on frequency: episodes per month, attacks per year, dilatations per year. A veteran who never logged symptoms hands the rater an empty column. Contemporaneous treatment notes and a structured severity record change that.
Written Off as Diet and Lifestyle
Reflux and bowel complaints are common in the general population, and a bare reference to diet is the digestive equivalent of the aging objection. It can be answered with pharmacology, the prescription timeline, and symptom onset relative to treatment.
Medication Chains Without Pharmacy Records
The strongest GI secondary theory is often a prescription history nobody assembled. Which drug, prescribed for which service-connected condition, starting when, at what dose. Without that timeline the mechanism is a theory. With it, the theory is documented.
Normal Scopes, Real Disability
IBS is identified largely by exclusion, and a clean colonoscopy does not defeat the claim. Functional gastrointestinal disorders are recognized in the schedule and presumptive for Gulf War veterans under 38 CFR 3.317, which is a different route entirely.
Medical Evidence Services for Gastroenterology Claims
Clinician-led services support gastroenterology claims at different stages. Each focuses on the medical evidence — clear diagnoses, sound causation reasoning, and well-documented severity.
Independent Medical Opinion / Nexus Letter
A clinician's written opinion on whether a condition is at least as likely as not connected to service, with the supporting medical rationale.
When you need to establish or strengthen the causal link — particularly for secondary claims or a claim that was previously denied.
Purpose: A clinician's written opinion on whether a condition is at least as likely as not connected to service, with the supporting medical rationale. When It May Help: When you need to establish or strengthen the causal link, particularly for secondary claims or a claim that was previously denied. For Gastroenterology Claims: Writes the mechanism in full: how SSRIs and chronic stress produce reflux, how NSAIDs strip gastric protection, how the gut-brain axis links a service-connected mental health condition to bowel disease. Anchors the opinion to the pharmacy timeline, answers the diet objection directly, and covers direct, secondary, and aggravation theories in one letter.
Disability Benefits Questionnaire (DBQ)
Standardized disability questionnaires completed by licensed clinicians to evaluate the severity of your conditions according to VA rating criteria.
When you are filing for an initial rating, an increase, or need to document current functional impairment for a C&P exam.
Purpose: Standardized disability questionnaires completed by licensed clinicians to evaluate the severity of your conditions according to VA rating criteria. When It May Help: When you are filing for an initial rating, an increase, or need to document current functional impairment for a C&P exam. For Gastroenterology Claims: Documents the specifics the revised criteria measure: episode frequency and character for IBS, dysphagia and dilatation history for GERD under DC 7206, exacerbations, weight change, and nutritional impact for inflammatory bowel disease. Severity fields left blank are ratings left on the table.
Claim Readiness Review
A pre-filing review of your medical records to identify what is already documented and what evidence may be missing.
Before filing or refiling, when you want a clear, honest picture of where a claim stands medically.
Purpose: A pre-filing review of your medical records to identify what is already documented and what evidence may be missing. When It May Help: Before filing or refiling, when you want a clear, honest picture of where a claim stands medically. For Gastroenterology Claims: Checks whether the diagnosis is actually in the record or only in your history, whether the prescription timeline supports the medication theory, which version of the rating criteria governs your claim, and whether the single evaluation rule affects how your conditions should be filed. Before you file, not after the denial.
Veterans Usually Pair Gastroenterology With These Systems
Gastroenterology pairs most often with mental health (the medication and gut-brain chains behind GERD and IBS), musculoskeletal (the NSAID chain from service-connected joints), and pulmonology (reflux aggravating airway disease and fragmenting sleep).
Frequently Asked Questions
Yes. Most digestive conditions can be service connected when the medical record supports a link to service. That link may be direct, where the condition began in service, secondary, where another service-connected condition or its treatment caused or worsened the digestive problem, or aggravation, where a pre-existing condition got permanently worse.
Secondary service connection is the most common pathway in this body system, because most digestive conditions develop years after separation, usually downstream of a service-connected condition or its medications.
A nexus letter explains the medical connection. Whether any claim succeeds is a determination for the VA.
Yes, through two documented pathways. Medications such as SSRIs and SNRIs prescribed for service-connected PTSD, anxiety, or depression can increase gastric acid production and reduce lower esophageal sphincter tone, allowing acid to reflux into the esophagus. Chronic stress also disrupts the HPA axis, which affects gastric motility and acid secretion. A useful opinion identifies which pathway your pharmacy records and symptom timeline actually support, and writes the mechanism out in full.
The VA rewrote the digestive rating schedule effective May 19, 2024 and gave GERD its own code, Diagnostic Code 7206, rated at 0, 10, 30, 50, or 80 percent on esophageal stricture criteria such as dysphagia and the need for dilatation.
Before that date, GERD was rated by analogy under DC 7346 at 10, 30, or 60 percent based on symptoms like epigastric distress, pyrosis, and regurgitation. The two versions measure very different things: the old criteria rated the burning, the new ones rate the swallowing.
The revised criteria apply to claims received or pending on or after May 19, 2024, and claims pending on that date are evaluated under whichever version is more favorable. Which version governs your claim changes what your evidence needs to document, and we address it during record review.
It depends on which criteria govern your claim. Under 38 CFR 4.114, ratings under certain digestive diagnostic codes are not combined with each other. Instead, a single evaluation is assigned under the code reflecting the predominant disability picture, with elevation to the next higher level where the overall severity warrants it.
Under the pre-2024 rules, GERD under DC 7346 and IBS under DC 7319 both sat inside that rule, so veterans with both conditions typically carried one digestive rating rather than two.
Under the revised schedule, GERD moved to DC 7206 in the esophagus group, which sits outside the single evaluation rule. Separate ratings became possible for claims governed by the new criteria, which is one more reason the effective date question matters to your file.
Yes. IBS and other functional gastrointestinal disorders are presumptive under 38 CFR 3.317 for veterans with qualifying Gulf War service. Presumptive service connection removes the burden of proving direct causation, but a current diagnosis and documentation of symptom frequency and severity are still required for rating purposes. The revised DC 7319 criteria, effective May 19, 2024, also made every IBS rating compensable and added a 20 percent tier.
Yes, through direct service connection if the disease began or worsened during service, or through secondary service connection. Peer-reviewed research on the gut-brain-immune axis describes how chronic stress from conditions like PTSD contributes to immune dysregulation, increased intestinal permeability, and altered microbiome composition, which can trigger or worsen inflammatory bowel disease. These claims fail most often because the opinion asserts the connection in a sentence instead of explaining the mechanism, or never addresses causation versus aggravation.
Yes. NSAIDs inhibit the protective prostaglandins that maintain the stomach lining, and years of prescribed anti-inflammatory therapy for a service-connected back or knee carry documented gastrointestinal risk, including gastritis, peptic ulcer disease, and worsened reflux. Pharmacy records make this argument concrete. The prescription history and the symptom timeline together are what turn a plausible theory into a documented one.
The gut-brain axis is the two-way communication network between the central nervous system and the digestive system. Chronic psychological stress alters gut motility, increases intestinal permeability, and disrupts the gut microbiome. It is the medical mechanism behind many claims for IBS and other digestive conditions secondary to PTSD, anxiety, or depression. A rater cannot weigh a mechanism nobody wrote down, so a useful opinion explains it in plain terms and cites the supporting research.
Three reasons come up again and again. The opinion asserts the connection without explaining the pathophysiology. The medication timeline is never documented, so nothing in the file shows the digestive symptoms began after the prescription did. Or the opinion never addresses aggravation, leaving the rater with no answer to the objection that the condition would have developed anyway. Each of these is answerable, and a rebuttal opinion after a denial addresses the specific reasoning the file lacked.
That is the normal fact pattern, not a defect. Most conditions in this body system develop years after separation, which is exactly why secondary service connection dominates gastroenterology claims. If your GERD developed after you started an SSRI for service-connected PTSD, or your ulcer followed years of prescribed NSAIDs for a service-connected knee, the connection runs through the service-connected condition and its treatment, not through an in-service GI entry.
Usually not. Once the diagnosis is documented, the question in most digestive claims is causation, and that is reasoning rather than testing.
A board-certified internist at $945 handles most GERD, IBS, and medication-chain claims, with every supported theory in one letter. A gastroenterologist, from $1,600, earns the cost where the diagnosis itself is contested, where endoscopy, colonoscopy, or biopsy findings need specialist interpretation, or where the negative opinion came from a specialist and you need equal or greater authority on your side.
We match the clinician to the medical question rather than defaulting to the most senior credential, and we will tell you which tier fits before you pay.
They answer different questions. A nexus letter establishes the connection between the condition and service. A DBQ documents current severity: episode frequency, symptom patterns, weight change, and treatment requirements, which is what drives the rating percentage. Under the revised criteria, severity documentation matters even more, because ratings turn on specifics like dilatation frequency for GERD and documented episode patterns for IBS. Many veterans benefit from pairing both.
Yes. Under 38 CFR 3.159(a)(1), competent medical evidence includes opinions from private physicians and other qualified medical professionals. The VA must weigh a private opinion on its merits: the quality of its reasoning, the accuracy of its factual foundation, and the qualifications of the provider, not on whether the veteran paid for it.
It is the medical-evidentiary standard used in nexus opinions. It means the probability of a connection is at least 50 percent, as likely as not. A clinician uses it to state, in medical terms, whether a condition is reasonably connected to service. It is a medical opinion, not a legal determination.
A discovery call is a no-obligation conversation about your digestive condition, your service-connected ratings, and your goals.
We talk through which pathways might fit, whether that is a medication chain from PTSD or pain treatment, a gut-brain secondary theory, or a Gulf War presumptive, and explain whether additional medical evidence would help.
Bring your rating decision, your medication list with approximate start dates, and any endoscopy or imaging reports.
There is no pressure to proceed. If a letter would not add value to your claim, we will tell you that instead.
