Celiac Disease VA Claims Guide
Celiac disease is an autoimmune reaction to gluten that damages the small intestine and interferes with nutrient absorption. As of the May 19, 2024 digestive-system update, the VA rates it under its own diagnostic code, DC 7355, on a malabsorption ladder that runs from 0 to 80 percent. This guide walks the whole path: how service connection works, how celiac gets connected to your service, what evidence you need, why these claims get denied, a checklist before you file, what the claims process looks like step by step, how to read your decision letter, and what to do whether you win or you're denied. It is a reference, not advice about your specific claim.
What Celiac Disease Is, and How It Is Confirmed
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.
How Service Connection Works, At a High Level
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.
- 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.
- 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.
- 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.
What VA Looks For: Tests, Records, and Diagnostic Codes
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.
How Celiac Disease Gets Service Connected
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.
Direct Service Connection
The standard three parts: a current diagnosis, an in-service event or onset, and a medical nexus tying them together. Service treatment records showing chronic abdominal pain, diarrhea, or unexplained weight loss during service strengthen the timeline, even if the formal diagnosis came later. This has been the most consistent path to a grant in published decisions. See service connection.
Secondary Service Connection (38 CFR § 3.310)
Celiac can be claimed as caused or aggravated by another service-connected condition, with a nexus opinion stating it is at least as likely as not related. In practice this is a harder pathway for celiac specifically than it is for many other conditions: in published decisions, examiners have found that GERD, IBS, and PTSD do not cause celiac disease, and secondary theories on that basis have generally been denied. Veterans sometimes argue that a service-connected autoimmune condition, Gulf War illness, or chronic stress contributed to the onset of celiac in a genetically predisposed person; treat this as a theory worth raising alongside a direct claim, not a substitute for one. The reverse direction, celiac as the primary condition behind another secondary claim, is common and is covered separately below.
A related illness may qualify under the Gulf War presumptive, even when celiac itself does not
The Persian Gulf presumptive rules at 38 CFR § 3.317 can sometimes help a related, medically unexplained gut illness rather than celiac disease itself. Published decisions have granted a functional gastrointestinal disorder under this presumption when the diagnosis was something other than celiac (for example, small intestine bacterial overgrowth). This is a different diagnosis on a different theory, not a shortcut to a celiac grant, but it is worth knowing if your gut symptoms don't cleanly map to a celiac diagnosis.
Aggravation and Toxic Exposure
If celiac existed before service and service made it worse, an aggravation claim with a supporting medical opinion is available under 38 CFR § 3.306. Some claims also raise documented toxic exposure (burn pits, solvents, contaminated water) as a direct-nexus theory, since research links environmental toxins to autoimmune activation. Toxic exposure is not a presumptive shortcut for celiac; it has to be developed as a direct medical link explaining the specific mechanism, not argued on its own. See toxic-exposure appeals.

How the VA Rates Celiac Disease, DC 7355
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. A controlled case with no residuals can be rated 0 percent; the compensable levels are 30, 50, and 80 percent.
The 2024 Change, and the Increase Opportunity
Before May 19, 2024, celiac had no dedicated diagnostic code and was rated by analogy to another digestive condition. The digestive-system amendment created DC 7355 with its own malabsorption criteria and a top schedular level of 80 percent.
Evidence That Wins These Claims
Across 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)).
Why These Claims Get Denied
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.
- A confirmed diagnosis with no connection to service. Having celiac disease, even a clearly documented case, is not enough by itself. Claims are denied where the disability plainly exists but nothing in the record ties it to service.
- Toxic or burn-pit exposure argued alone. Celiac is not on the PACT Act presumptive list, and examiners routinely treat it as genetic rather than caused by environmental toxins. A claim that rests only on general exposure argument, with no medical opinion explaining a specific mechanism, is a weak claim on its own.
- A bare doctor's note with no explanation. The Board gives little weight to an opinion that reaches a conclusion without a factual basis or reasoning, and to an opinion resting on a single general research article instead of the veteran's own facts (Nieves-Rodriguez v. Peake, 22 Vet. App. 295 (2008); Stefl v. Nicholson, 21 Vet. App. 120 (2007)).
- A long, unexplained gap after service. A diagnosis that first appears many years after discharge weighs against a claim unless the record ties it back to service with corroborating history or evidence.
- A secondary theory resting only on a claimed link from GERD, IBS, or PTSD. Examiners have found these conditions do not cause celiac disease; a secondary theory needs its own supporting medical reasoning, not just the presence of another service-connected digestive or mental health condition.
Pitfalls and Common Mistakes
- No biopsy or serology in the file. Celiac is confirmable; a claim resting on symptoms alone, without the antibody tests or biopsy, gives the rater no objective diagnosis to work from.
- Confusing celiac with IBS or GERD. These are rated under entirely different codes (DC 7319 and DC 7206). A celiac claim filed and documented as IBS can be rated on the wrong, lower ladder.
- No nutritional labs. The 50 and 80 percent levels turn on documented deficiencies and wasting. Records that describe diarrhea without the iron, vitamin, and weight data leave the higher levels unsupported.
- An old rating left untouched. A pre-2024 rating is not updated automatically; reaching the new 80 percent level generally requires filing for an increase.
- Missing a scheduled VA exam. An otherwise arguable claim can be denied on the record when a veteran does not attend scheduled exams and gives no good reason (38 CFR § 3.655). The duty to assist is not a one-way street.
- Not returning requested forms. If VA asks for a records-release authorization or other paperwork, returning it promptly keeps development moving; ignoring it can leave a claim decided on an incomplete record.
Do's and Don'ts
A condensed version of everything above, in the order it actually matters when you sit down to build your file.
- Get and keep proof of your current celiac diagnosis (antibody blood test or endoscopy with biopsy).
- Get a nexus opinion that explains its reasoning and applies the medical literature to your own facts, not a bare conclusion.
- Write down when your stomach symptoms started and how they have continued, in your own words.
- Gather service treatment records and separation exam notes that mention diarrhea, cramps, or stomach problems.
- Raise every theory that fits your case, direct, secondary, and toxic-exposure, since one theory can succeed even if another fails.
- Track nutritional labs (iron, vitamin D, B12, folate, calcium) and your weight history to support the 50 or 80 percent levels.
- Attend every VA exam and return every form VA sends, promptly.
- If you were rated before May 19, 2024 and now have nutritional deficiencies or wasting, file for an increased evaluation.
- Don't assume a diagnosis alone wins the claim, you still need the connection to service.
- Don't rely only on toxic exposure, burn pits, herbicides, or Camp Lejeune water; celiac is treated as genetic and isn't presumptive, so build a direct medical link.
- Don't submit a bare doctor's note with no rationale, or an opinion that leans on a single general article instead of your own facts.
- Don't let a long gap after service go unexplained; fill it with records or credible symptom history.
- Don't file celiac as IBS or GERD, or let those codes get mixed together in your claim.
- Don't ignore VA letters or skip a scheduled exam.
- Don't assume VA will automatically re-rate an old rating under the new DC 7355 criteria.
Secondary Conditions Celiac Disease Commonly Causes
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.
See the secondary conditions overview and the secondary map on the DC 7355 page.

Quick Checklist Before You File
Bring these together before you submit anything.
- Proof of your current celiac diagnosis (antibody blood test or endoscopy with biopsy).
- A written account of when your stomach symptoms started and how they have continued, in your own words.
- Service treatment records and separation exam notes that mention diarrhea, cramps, or stomach problems.
- A nexus opinion that explains why your celiac is linked to service, not just a one-line note.
- A plan for the toxic-exposure question: don't rely on it alone, since celiac is treated as genetic and is not presumptive.
- Nutritional labs and weight history if you're already service-connected and pursuing a higher rating level.
- A plan to attend every scheduled VA exam and return every form VA sends, promptly.
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).
The Claims Process, Step by Step
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.
- You file the claim. Directly with VA, through VA.gov, or with the help of an accredited representative.
- 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.
- 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.
- 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.
- 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.
- A senior reviewer may review the decision before it's finalized, depending on the complexity of the claim.
- 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.
- 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
Your VSO
An accredited representative from a veterans service organization, or an accredited attorney or claims agent. Not a VA employee. Helps you prepare, gather evidence, and file, and can represent you through an appeal. Has no authority to decide your claim.
VSR (Veteran Service Representative)
VA staff who "develops" your claim: requests records, schedules the C&P exam, and assembles the file. Does not decide the rating.
Rater (RVSR)
VA staff who reviews the completed file and makes the actual decision, service connection or denial, and the percentage. This is the person whose judgment the decision letter reflects.
C&P Examiner
A VA clinician or a contracted medical examiner who conducts the exam and completes the DBQ. Documents findings and, where asked, a nexus opinion. Does not decide the claim.
For the full walkthrough of every stage with more detail, see Inside Your Claim and Claim Stages.
DBQs and Your C&P Exam
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.
Reading Your Decision Letter, and What to Do If Denied
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.
After You Win: Rating, Effective Date, and Maintaining It
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 gluten-free diet cannot be held against you. VA cannot count the ameliorative effect of a medically prescribed diet or medication against you when rating how severe your underlying condition is (Jones v. Shinseki, 26 Vet. App. 56 (2012)). If the diet is controlling your symptoms, the record should still reflect the deficiencies and severity the diet is managing.
- 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.
