Acid reflux and GERD are among the most common — and most overlooked — secondary VA disabilities. If you take ibuprofen or naproxen for a service-connected joint or back condition, if you have service-connected PTSD or anxiety, or if you have a spinal cord injury that affects your nervous system, your GERD may be directly caused by your military service. Under Diagnostic Code 7346, GERD is rated from 10% to 60%, and even a 10% rating adds $175.51 per month to your compensation. This guide walks through every secondary pathway, the evidence you need, and how to write the nexus that gets it approved.
Gastroesophageal reflux disease — GERD — affects roughly 20% of Americans, but veterans develop it at significantly higher rates due to the physiological and pharmacological demands of military service and its aftermath. Despite how common it is, the majority of veterans with service-connected GERD never claim it as a separate disability.
That's a significant financial mistake. The VA rates GERD under Diagnostic Code 7346 (Hiatal Hernia), which covers the full spectrum of gastroesophageal reflux conditions. The rating scale runs from 10% to 60%, and with the 2025 VA compensation rates:
Secondary service connection under 38 CFR 3.310 means the VA will compensate you for a disability that is caused or aggravated by an already service-connected condition. You don't need to connect GERD to a specific incident in service — you only need to show it flows from something that is already service-connected. This is a critical distinction many veterans miss.
Secondary service connection does not require a direct in-service event. If GERD is caused or aggravated by a service-connected condition — such as the NSAIDs you take for your rated back pain — it qualifies for separate VA compensation under 38 CFR 3.310.
This is the most common and most straightforward pathway for GERD secondary service connection — and one of the most frequently missed by veterans and even VSOs.
Nonsteroidal anti-inflammatory drugs (NSAIDs) — including ibuprofen (Motrin, Advil), naproxen (Aleve, Naprosyn), aspirin, and prescription-strength NSAIDs like meloxicam, diclofenac, and indomethacin — are the first-line treatment for chronic musculoskeletal pain. Veterans with service-connected back pain, knee injuries, shoulder conditions, hip conditions, and other joint problems are routinely prescribed or advised to take NSAIDs long-term.
The problem: NSAIDs are gastrotoxic. They work by inhibiting cyclooxygenase (COX) enzymes, which reduces prostaglandin production. Prostaglandins are partly responsible for maintaining the protective mucus lining of the stomach and esophagus. When that protective barrier is weakened by chronic NSAID use, the result is acid erosion of the gastric lining, increased acid reflux, and clinically diagnosable GERD.
The medical literature on this is unambiguous. Long-term NSAID use is the leading cause of medication-induced peptic ulcer disease and GERD. For a veteran who has been taking ibuprofen or naproxen for years to manage service-connected back pain or knee pain, the causal chain is direct:
If your VA medical records or private treatment records show NSAID prescriptions alongside your service-connected musculoskeletal condition, you have the core building block for a secondary GERD claim. A gastroenterologist or any physician familiar with pharmacology can write the nexus connecting NSAID use to your GI symptoms.
"It is at least as likely as not that the veteran's GERD (gastroesophageal reflux disease) is caused by long-term NSAID use required to manage the service-connected [lumbar disc disease / knee condition / etc.]. NSAIDs inhibit protective prostaglandin synthesis in the gastric mucosa, a well-established mechanism for inducing gastroesophageal reflux and peptic ulcer disease."
The gut-brain axis is one of the most studied topics in modern gastroenterology. The connection between psychological stress, anxiety, and gastrointestinal disease is not a folk remedy — it is a well-established physiological mechanism documented across hundreds of peer-reviewed studies.
Stress and anxiety activate the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system, which together increase cortisol and catecholamine levels. These hormones affect gastric motility, increase gastric acid secretion, alter lower esophageal sphincter tone, and heighten visceral sensitivity. The practical result: veterans with service-connected PTSD or anxiety disorders experience significantly elevated rates of GERD, irritable bowel syndrome, functional dyspepsia, and peptic ulcer disease.
Research published in the Journal of Psychosomatic Research and other peer-reviewed journals has documented that PTSD specifically is associated with increased rates of functional GI disorders, including GERD. A 2014 study found that veterans with PTSD had substantially higher rates of GI disorders compared to veterans without PTSD, even after controlling for other variables.
For veterans who already have service-connected PTSD (especially those rated at 50%, 70%, or 100%), adding a GERD secondary claim under this pathway can meaningfully increase overall compensation — especially if the base rating is below the threshold where combined math produces rounding up.
The nexus letter for this pathway should reference:
A VA psychiatrist, primary care physician, or gastroenterologist can all write this nexus effectively. If your VA provider already notes GI symptoms in the context of your PTSD treatment, those records already partially build your case.
Veterans with service-connected spinal cord injuries (SCI), multiple sclerosis, traumatic brain injury (TBI), or other neurological conditions affecting the autonomic nervous system face a distinct physiological mechanism for GERD development.
The vagus nerve — the tenth cranial nerve — is the primary parasympathetic controller of gastrointestinal function. It regulates esophageal peristalsis, lower esophageal sphincter tone, gastric emptying, and digestive motility throughout the GI tract. When spinal cord injuries or neurological conditions damage vagal pathways, the result is disrupted GI motility, gastroparesis, and abnormal lower esophageal sphincter function — all of which directly cause or worsen GERD.
Spinal cord injuries at the cervical or thoracic level are particularly likely to affect vagal function and GI motility. Studies have consistently shown that veterans with SCI report GI complications — including GERD, constipation, and bowel dysfunction — as among their most disabling secondary conditions.
For veterans with service-connected SCI, GERD is essentially expected and well-documented in the medical literature. A nexus letter in this context is relatively straightforward for any physician familiar with SCI-related complications.
GERD is rated under Diagnostic Code 7346 (Hiatal Hernia) in 38 CFR Part 4. The rating criteria are based on symptom frequency and severity:
| Rating | Criteria | 2025 Monthly Rate* |
|---|---|---|
| 10% | Two or more of the following: pyrosis (heartburn), regurgitation, or substernal or arm pain following meals or exercise | ~$175.51 added |
| 30% | Persistently recurring epigastric distress with dysphagia (difficulty swallowing), pyrosis, and regurgitation, accompanied by substernal or arm pain | Depends on combined |
| 60% | With pain, vomiting, material weight loss, and hematemesis or melena (blood in stool or vomit); or other severe symptoms | Depends on combined |
*Additional monthly amount depends on your current combined rating. Use the VA Rating Estimator to calculate the exact impact on your total compensation.
Most veterans with moderate GERD symptoms will fall in the 10%–30% range. Even a 10% rating is meaningful — and if your symptoms are frequent and significantly impair daily life (difficulty swallowing, frequent regurgitation, persistent epigastric pain), a 30% rating is achievable.
The 60% rating requires severe documented symptoms including weight loss or GI bleeding. This typically applies to veterans with complicated GERD leading to esophageal erosion, Barrett's esophagus, or significant structural damage.
For the 10% rating, you need to document at least two of three symptoms. In plain language:
If you have two of these regularly, you meet the 10% threshold. Keep a symptom diary for 30–60 days leading up to your C&P exam. Frequency matters: "occasional" symptoms versus "persistent" symptoms will determine whether you land at 10% or 30%.
Many veterans have GERD that is being treated — but they have never formally claimed it as a VA disability. Here's the tell: look at your current medication list, whether from the VA or civilian providers.
If you are prescribed or regularly take any of the following, you very likely have a documented GERD diagnosis:
If omeprazole or pantoprazole appears in your VA medication records, the VA has already documented and treated your GERD. You may have a current diagnosis on file that you didn't realize exists. Pull your Blue Button report from My HealtheVet and check both your problem list and your medication list. The diagnosis may already be there — waiting for you to file the secondary claim.
Log into My HealtheVet, go to Health Records → Blue Button, and download your full health summary. Search for "GERD," "gastroesophageal reflux," "hiatal hernia," "esophagitis," or the medication names above. If any appear, you already have documentary evidence of a current diagnosis — the hardest piece of the secondary claim puzzle.
The VA uses a combined ratings formula rather than simple addition. Understanding the math helps you prioritize which secondary claims matter most for your bottom line.
Consider a veteran already rated at 70% PTSD and 30% sleep apnea. Their combined rating using the VA formula is approximately 79% — which rounds to 80%. Adding a 10% GERD rating to this combination yields a combined of roughly 81% — which still rounds to 80%. In this scenario, the 10% GERD doesn't increase the total rating, but it does lock in a rating even if one condition improves.
However, the calculation is very different if your base ratings are lower. Consider a veteran at 40% back pain and 20% tinnitus — combined roughly 52%, rounding to 50%. Adding 10% GERD brings the combined to approximately 57%, which rounds to 60% — a meaningful jump that increases monthly compensation by over $400.
The key takeaway: filing secondary claims is always worth doing, even if the immediate math doesn't show a jump. Conditions get worse over time, and having GERD on your record now means you can file for an increased rating when symptoms worsen. Use the Rating Estimator to run your own numbers.
A complete GERD secondary service connection claim requires three categories of evidence:
If you've received a denial, use the Denial Analyzer to identify exactly which evidence gap caused the denial and what you need to address on appeal.
The nexus letter is often the make-or-break document in a secondary claim. The VA rater is looking for specific language and a clear causal chain. Here is the core language structure for each pathway:
"Based on my review of [veteran's name]'s medical records and my clinical evaluation, it is my professional opinion that it is at least as likely as not that [veteran's name]'s gastroesophageal reflux disease (GERD) is caused by long-term NSAID use required for the management of [his/her] service-connected [condition]. NSAIDs inhibit COX-1 and COX-2 enzymes, reducing prostaglandin E2 production critical for maintaining gastric mucosal integrity. Chronic suppression of this protective mechanism is a well-established cause of gastroesophageal reflux disease and peptic ulcer disease, documented in [cite specific studies or standard medical texts]."
"It is at least as likely as not that [veteran's name]'s GERD is caused or aggravated by [his/her] service-connected PTSD. Chronic psychological stress and anxiety, as documented in [veteran's] treatment records, activates the HPA axis and stimulates gastric acid hypersecretion via central and peripheral mechanisms. Multiple peer-reviewed studies, including research published in the Journal of Psychosomatic Research, document the association between PTSD, chronic anxiety, and increased rates of gastroesophageal reflux disease."
If you have a service-connected musculoskeletal condition and you take NSAIDs — or if you have service-connected PTSD — there is a strong probability that your GERD qualifies as a secondary VA disability. The claim is not complicated, but it requires the right documentation executed in the right order.
