GERD Secondary to Sleep Apnea: VA Disability Claim Guide

Overview

Gastroesophageal reflux disease (GERD) is a condition in which stomach contents repeatedly flow back into the esophagus, causing heartburn, regurgitation, and sometimes inflammation or narrowing (stricture) of the esophagus. GERD and obstructive sleep apnea (OSA) frequently occur together. Veterans with service-connected OSA can claim GERD as secondary under 38 CFR § 3.310, either as caused by the apnea or as aggravated by it.

The two conditions share a major risk factor, obesity. That means the claim depends on a medical opinion that explains why the apnea itself contributes, not just that the two appear together. GERD is also rated on esophageal stricture under DC 7206, so many veterans with medication-controlled heartburn will be service-connected at 0%.

How GERD Is Connected to Sleep Apnea

The association. A 2026 meta-analysis of observational studies found that OSA was associated with nearly twice the odds of GERD (pooled odds ratio 1.96, from six studies with moderate heterogeneity) (Vega Sanchez et al., 2026). In a prospective cohort of 331 OSA patients, 62% reported nocturnal reflux before treatment (Green et al., 2003).

Negative chest pressure (the proposed mechanism). During an obstructive apnea, the airway is blocked while the diaphragm keeps pulling. This creates strongly negative pressure inside the chest, which is thought to favor reflux across the lower esophageal sphincter. Sleep fragmentation from repeated arousals may also impair the esophagus’s ability to clear acid.

Response to CPAP. In the same cohort, patients who stayed on CPAP reported a 48% improvement in nocturnal reflux symptoms, and higher CPAP pressures were associated with greater improvement. The small group that stopped CPAP showed no improvement (Green et al., 2003). For a claim, this matters: if treating the apnea reduces reflux, that supports the apnea contributing to it. If your own reflux improved on CPAP, or is worse on nights you can’t use it, have that documented.

CPAP and aerophagia. Some CPAP users swallow air, causing bloating and belching. Because the published data show CPAP generally reduces reflux, arguing that CPAP causes your GERD is weak unless your records show a clear worsening after starting it.

Shared risk factors. Obesity, alcohol, and certain medications raise the risk of both conditions. The opinion should address them rather than ignore them.

Evidence Requirements

• Current GERD diagnosis. VA’s Esophageal Conditions DBQ notes that GERD can be diagnosed clinically, by relief of typical symptoms with PPIs, H2 blockers, or antacids.
• Imaging or endoscopy for any stricture. Under DC 7206 Note (1), findings must be documented by barium swallow, CT, or EGD. Without this, the rating will be 0%.
• Service-connected sleep apnea. Your rating decision and your sleep study (AHI, oxygen desaturation).
• Timeline. Records showing when reflux began relative to OSA symptoms and diagnosis.
• CPAP records. Compliance data, and any documented change in reflux after starting treatment.
• GI treatment records: PPIs, H2 blockers, and any dilatations with dates.
• Lay statements describing nighttime reflux, such as waking with acid in the throat, night coughing, or morning hoarseness.

Nexus Letter Tips

Who should write it. A gastroenterologist, a sleep medicine physician, a pulmonologist, or your primary care provider. VA does not require a specialist; what matters is reasoning that fits your records.

What it should include:

1. Confirmation that the provider reviewed your records
2. Your GERD diagnosis and supporting findings
3. Your OSA severity and treatment history
4. The negative-pressure mechanism, and the published association and CPAP-response data, described accurately
5. Your own response to CPAP, if documented
6. Other risk factors (weight, alcohol, tobacco, medications, hiatal hernia) and why OSA is still at least as likely as not a cause or aggravating factor
7. The standard: “at least as likely as not” (50% or greater probability)

Aggravation. If reflux predated the apnea, the opinion can address aggravation under § 3.310(b). VA needs medical evidence of the baseline severity before the aggravation, or the earliest medical evidence between the onset of aggravation and the evidence of current severity. The rating is the current level minus that baseline.

Rating Criteria for GERD

GERD is rated under Diagnostic Code 7206 (Gastroesophageal reflux disease) in 38 CFR § 4.114, created in the digestive system update effective May 19, 2024. Before then, GERD was rated by analogy to DC 7346 (hiatal hernia), and older decisions and guides still show those criteria. DC 7206 rates GERD on documented esophageal stricture and its treatment, not on heartburn or overall health impact.

• 0%: Documented history without daily symptoms or requirement for daily medications
• 10%: Documented history of esophageal stricture(s) that requires daily medications to control dysphagia, otherwise asymptomatic
• 30%: Documented history of recurrent esophageal stricture(s) causing dysphagia which requires dilatation no more than 2 times per year
• 50%: Documented history of recurrent or refractory esophageal stricture(s) causing dysphagia which requires at least one of: dilatation 3 or more times per year, dilatation using steroids at least one time per year, or esophageal stent placement
• 80%: Documented history of recurrent or refractory esophageal stricture(s) causing dysphagia with aspiration, undernutrition, and/or substantial weight loss (as defined by § 4.112(a)), and treatment with either surgical correction of esophageal stricture(s) or a PEG tube

Monthly compensation at 10% (single veteran, no dependents, 2026): $180.42

What this means for your claim: The 10% level is about daily medication needed to control dysphagia (difficulty swallowing) from a documented stricture. Daily PPIs for heartburn alone do not meet it. If you have difficulty swallowing, tell your provider. Ask whether an EGD or barium swallow is appropriate, and keep records of every dilatation. See our GERD rating guide for the full criteria and notes.

Overlap with other ratings: GERD and sleep apnea are rated in different body systems, so rating both does not pyramid. If you also have a hiatal hernia (DC 7346, also rated as esophageal stricture), VA will not compensate the same swallowing problem twice (§ 4.14).

How to File This Secondary Claim

1. Confirm your sleep apnea is service-connected.
2. Get a GERD diagnosis documented. If you have trouble swallowing, ask about an EGD or barium swallow.
3. Build the record: consistent documentation of reflux symptoms, treatment, and any change with CPAP.
4. Get a nexus opinion.
5. File VA Form 21-526EZ on VA.gov, listing GERD as secondary to service-connected obstructive sleep apnea.
6. Upload your evidence: the nexus opinion, treatment records, procedure reports, and statements.
7. Attend the C&P exam. VA typically uses the Esophageal Conditions DBQ.

C&P Exam Tips

• Describe your symptoms accurately, including frequency and duration. Cover typical nights and bad nights, and separate heartburn from trouble swallowing (food sticking, needing to drink to get food down).
• Describe nighttime symptoms: waking with acid in the throat, night coughing, or morning hoarseness.
• Explain your CPAP experience: compliance, and whether reflux changed after you started.
• List every medication and procedure: PPIs, H2 blockers, antacids, and dilatations with dates.
• Mention complications already diagnosed, such as stricture or Barrett’s esophagus, and bring the reports.

Impact on Combined Rating

Example: A veteran rated 50% for sleep apnea (CPAP required) receives 10% for GERD.

1. Start with 50%: 50% of efficiency remains.
2. 10% of 50 = 5, for a combined value of 55.
3. 55 rounds up to 60%.

Example with an additional condition: A veteran has 50% for sleep apnea, 30% for another condition, and 10% for GERD:

1. 50 and 30 combine to 65 (30% of the remaining 50 = 15); 35 remains.
2. 10% of 35 = 3.5, giving 68.5, which is 69 in the § 4.25 table.
3. 69 rounds to 70%.

A 0% GERD rating does not change the combined rating.

GERD can also be the primary condition for further secondary claims. Barrett’s esophagus, for example, has its own code (DC 7207).
