Celiac Disease VA Claims Guide

Before getting into the specific pathways below, it helps to understand the three things every celiac claim ultimately has to show. This is the same basic test that applies to any VA disability claim (Shedden v. Principi, 381 F.3d 1163 (Fed. Cir. 2004)), just applied to this condition.

1. A current diagnosis. Proof you actually have celiac disease now, ideally confirmed by a blood antibody test or an endoscopy with biopsy. This part is usually the easiest once the lab work and biopsy are in the file.
2. An in-service cause or symptom. Something in service must connect: stomach symptoms that started on active duty, or an in-service event. Diarrhea, cramps, and abdominal pain documented or credibly described as beginning in service anchor this element.
3. A medical link (nexus). A doctor must tie the two together and explain the reasoning, not just state a conclusion. A gastroenterologist's opinion relating documented in-service diarrhea and abdominal pain to a later celiac diagnosis is the kind of nexus that has carried a claim.

Celiac is not on any presumptive list. It is a diagnosable autoimmune disease, so it does not ride the Gulf War functional-illness presumptive (38 CFR 3.317) the way IBS does. It is established by the ordinary paths below.

Whether you are filing directly, secondary to another condition, or for an increase, the record VA actually reviews centers on a small set of documents and data points.

• Serology: the tTG-IgA, EMA, or DGP antibody panel that first flags celiac disease.
• Small-bowel biopsy: the endoscopy report showing villous atrophy or crypt hyperplasia. The 50 percent rating criteria specifically reference atrophy shown on biopsy.
• Nutritional labs: iron, hemoglobin, vitamin D, B12, folate, and calcium results, and a weight history, which separate the 30, 50, and 80 percent rating levels.
• Gluten-free-diet records: when the diet started and whether symptoms persist despite strict adherence.
• The diagnostic codes involved: DC 7355 for celiac itself, plus whatever code applies to a condition you're differentiating from or connecting it to, for example DC 7319 (irritable bowel syndrome), DC 7206 (GERD), or DC 9434 (depression, when raised as a secondary mental health condition).
• The actual form the examiner fills out: the intestinal-conditions Disability Benefits Questionnaire (DBQ), discussed in more detail later in this guide.

We analyzed the Board's published DC 7355 decisions: a private nexus opinion in the file goes with a meaningfully different grant rate, shown below.

• Objective diagnosis: the tTG-IgA, EMA, or DGP serology and the small-bowel biopsy showing villous atrophy.
• Nutritional labs: iron, hemoglobin, vitamin D, B12, folate, and calcium results, which separate the 30, 50, and 80 percent levels.
• Weight and wasting records over time, which feed the 80 percent level.
• Gluten-free-diet history and notes on whether symptoms persist despite strict adherence.
• The intestinal-conditions DBQ, which captures malabsorption, deficiencies, and systemic manifestations. See the DBQ guide.
• A nexus letter that explains its reasoning, for service connection, or a buddy/lay statement on symptom continuity since service. The clearest path to a grant in published decisions is an opinion that spells out how the connection works, for example a gastroenterologist relating documented in-service diarrhea and abdominal pain to the later celiac diagnosis, rather than a bare conclusion with no rationale. See nexus letters and buddy statements.
• Credible, specific lay statements about when stomach symptoms started and how they continued. You are competent to describe what you felt and when, and the Board must consider it (Jandreau v. Nicholson, 492 F.3d 1372 (Fed. Cir. 2007)).

Beyond the general "no nexus" reason covered above, a few specific denial patterns show up often enough in published decisions to call out on their own. Among the Board's classified service-connection denials for celiac, here is what claims most often fell short on.

The 2024 criteria rate celiac on malabsorption severity, not on how often you have a bad day. Each level builds on the one below it. DC 7355 lists three levels, 30, 50, and 80 percent. It has no 0 percent level of its own, so where a service-connected celiac condition does not meet the 30 percent criteria, the 0 percent comes from 38 CFR 4.31, the general rule supplying a 0 percent evaluation whenever a code lists none.

A condensed version of everything above, in the order it actually matters when you sit down to build your file.

Celiac disease is not a food intolerance and not the same as irritable bowel syndrome. It is an autoimmune disease: eating gluten triggers the immune system to attack the lining of the small intestine, flattening the finger-like villi that absorb nutrients (villous atrophy). The result is malabsorption, which is why the rating is built around nutritional consequences rather than bowel habits alone.

Unlike IBS, celiac is confirmable on objective testing, and the VA looks for it:

• Blood tests: elevated tissue transglutaminase antibodies (tTG-IgA), endomysial antibodies (EMA), or deamidated gliadin peptides (DGP).
• Small-intestine biopsy: villous atrophy, crypt hyperplasia, or related damage from gluten exposure.
• Response to a gluten-free diet: treatment records showing how long the diet has been in place and whether symptoms persist despite it.

Before May 19, 2024, celiac had no dedicated diagnostic code and was rated by analogy under 38 CFR 4.20, which tells VA to use the listed condition closest in the functions affected, the anatomical location, and the symptoms. Irritable colon syndrome (DC 7319) was a common choice, but it was not a rule: where malabsorption was the predominant problem, a code such as resection of the small intestine (DC 7328) or ulcerative colitis (DC 7323) could fit the record better, and the ceiling followed whichever code was used. The digestive-system amendment created DC 7355 with its own malabsorption criteria and a top schedular level of 80 percent.

Because celiac interferes with absorption across the body, its complications are frequently rated as their own service-connected conditions once celiac itself is service-connected. Each needs its own diagnosis and a nexus tying it to the celiac disease.

• Anemia and vitamin deficiencies. Iron-deficiency anemia and low vitamin D, B12, folate, or calcium, documented on labs even after a gluten-free diet.
• Dermatitis herpetiformis. The blistering, intensely itchy skin manifestation of celiac, confirmed by dermatology or skin biopsy and rated as a skin condition.
• Osteoporosis or low bone density. From long-term calcium and vitamin D malabsorption, shown on a DEXA scan.
• Peripheral neuropathy and cognitive symptoms. Tingling or numbness, or "brain fog," tied to celiac-related inflammation or deficiency.
• Mental health conditions. Depression or anxiety connected to chronic illness and strict dietary limits, rated under 38 CFR 4.130.
• Migraines and headaches. Recurrent headaches some veterans link to deficiency or flares.

RateMyVSO does not yet have enough coded published Board decisions to show a live secondary-condition grant-rate breakdown for DC 7355 the way it does for higher-volume codes. Check the DC 7355 page as the underlying data grows.

Bring these together before you submit anything.

For the mechanics of actually submitting the claim, see the Standard Claim Guide and the Fully Developed Claim Guide (filing with all your evidence up front can speed up the decision).

Once you file, your claim moves through a series of hand-offs. Understanding who does what helps you know who to contact, and what to expect, at each stage.

1. You file the claim. Directly with VA, through VA.gov, or with the help of an accredited representative.
2. VA acknowledges the claim and assigns it for development. A Veteran Service Representative (VSR) is assigned to gather your service treatment records, VA and private medical records, and any other evidence needed.
3. The VSR orders a Compensation & Pension (C&P) exam if one is needed. Not every claim requires one, but most celiac claims do, especially where a diagnosis or nexus opinion needs confirming.
4. The C&P exam is conducted. By a VA clinician or a contracted examiner, who completes an intestinal-conditions Disability Benefits Questionnaire (DBQ) documenting the diagnosis, malabsorption findings, and, where relevant, a nexus opinion.
5. The file goes to a Rating Veteran Service Representative (RVSR), the "rater." The rater reviews the complete file, including the exam results and nutritional labs, and decides whether service connection is warranted and at what percentage.
6. A senior reviewer may review the decision before it's finalized, depending on the complexity of the claim.
7. VA issues the decision letter. This states whether the claim is granted or denied, the rating percentage if granted, and the reasons behind the decision.
8. If you disagree, you choose an appeal lane. Higher-Level Review, Supplemental Claim, or a Board appeal, covered later in this guide.

Who's who: VSO vs. VSR vs. Rater vs. C&P Examiner

For the full walkthrough of every stage with more detail, see Inside Your Claim and Claim Stages.

A Disability Benefits Questionnaire (DBQ) is the standardized form an examiner completes for your condition, it structures the exam findings into the specific data points VA's rating schedule requires (for celiac, that includes the malabsorption findings, nutritional deficiencies, weight history, and systemic manifestations). See the DBQ Guide for how these forms work, including whether a private DBQ completed by your own doctor can be submitted instead of relying solely on a VA exam.

Before your C&P exam, bring your recent lab work, a clear timeline of your gluten-free diet and whether symptoms persist despite it, and a specific account of your worst days, not just how you feel on an average day. Be consistent with what's already in your medical records and prior statements. For a full walkthrough of what to expect and how to prepare, see the C&P Exam Prep Guide.

Your decision letter has two parts: a narrative section explaining the reasoning (often called "reasons and bases"), and a codesheet showing the actual rating percentage, the effective date, and the diagnostic code used. See the Reading Your Decision Letter Guide for how to find and interpret each part, or use the Letter Interpreter tool to upload your own letter and get a plain-English breakdown.

If your claim is denied, or the rating is lower than you expected, you have three main lanes:

• Supplemental Claim: refile with new and relevant evidence, such as a new nexus opinion or updated labs. See Supplemental Claim Guide.
• Higher-Level Review (HLR): a senior reviewer looks at the same evidence again for a difference of opinion, no new evidence is added. See HLR Guide.
• Board Appeal: your case goes to a Veterans Law Judge at the Board of Veterans' Appeals, with options for a direct review, an evidence docket, or a hearing. See Appeals decision guide.

Not sure which lane fits your situation? See the Appeals decision guide for a side-by-side comparison of all three.

A grant is not always the end of the story. A few rules specific to celiac and to VA claims generally are worth knowing once you're service-connected:

• Your prescribed gluten-free diet is part of the criteria, not a mark against you. The 30 and 50 percent levels of DC 7355 expressly describe malabsorption with chronic diarrhea managed by a medically prescribed dietary intervention such as a prescribed gluten-free diet. Being on the diet is how those levels are written, so it is not a reason to rate you lower. What separates the levels is what the diet leaves behind: the nutritional deficiencies and systemic manifestations documented while you are on it. Keep nutritional labs, biopsy findings, and weight history in the record. (Jones v. Shinseki, 26 Vet. App. 56 (2012), bars VA from denying a higher rating because treatment relieves symptoms when the diagnostic code says nothing about treatment. DC 7355 does address it, which is why the question here is what remains despite the diet rather than what the diet fixes.)
• The effective date is usually the date you filed, not when symptoms began. Even if your stomach problems started in service, your effective date is generally the date you filed the claim or your intent to file, not an earlier date tied to symptom onset (38 CFR § 3.400; 38 U.S.C. § 5110).
• Keep your treatment consistent. Continued follow-up with a gastroenterologist, updated nutritional labs, and records showing whether the gluten-free diet is or isn't fully controlling symptoms protect you if VA schedules a future reexamination. Not every rating gets reexamined; understand when a rating becomes protected from future review and what to do if VA proposes to reduce it. See Protect Your Rating and Future Reexaminations.
• If your celiac worsens, for example new nutritional deficiencies or wasting appear after the initial grant, you can file for an increased rating. See the Rating Increase Guide.
