If your sleep apnea is already service-connected and you now have gastroesophageal reflux disease, you can claim GERD secondary to sleep apnea for VA disability compensation by filing a secondary service connection claim under 38 CFR 3.310. You need a current GERD diagnosis, your existing sleep apnea rating, and a medical nexus opinion linking the two. Under a rule effective May 19, 2024, GERD is rated on its own diagnostic code from 0 to 80 percent.
What You Have to Prove
Secondary service connection under 38 CFR 3.310 treats a condition caused or worsened by an already service-connected disability as part of that original disability for benefits purposes.1eCFR. 38 CFR 3.310 – Disabilities That Are Proximately Due to, or Aggravated by, Service-Connected Disease or Injury Three elements have to line up:
- Your obstructive sleep apnea is already rated by the VA.
- A doctor has diagnosed you with GERD. Symptoms without a formal diagnosis will not carry the claim.
- A qualified provider states that your sleep apnea caused or aggravated your GERD.
Aggravation matters as much as causation and gets overlooked. If you had mild GERD before your sleep apnea worsened it, the increase in severity is compensable, but the VA will measure your baseline and pay only for the added disability. Your records need to show what your GERD looked like before the sleep apnea made it worse.1eCFR. 38 CFR 3.310 – Disabilities That Are Proximately Due to, or Aggravated by, Service-Connected Disease or Injury
The Medical Link Your Nexus Letter Should Explain
Every apnea episode collapses your airway and forces you to breathe against that obstruction. The resulting negative pressure inside the chest cavity widens the pressure gap across the lower esophageal sphincter and pulls stomach contents upward. Research has tied this increased transdiaphragmatic pressure directly to acid reflux, with the forceful breathing that follows each event driving gastric contents further in the wrong direction.2MDPI. Obstructive Sleep Apnea Is Associated with an Increased Risk of Gastroesophageal Reflux Disease
Sleep apnea also slows gastric emptying and triggers reflexive relaxation of the sphincter that normally keeps acid down. Hundreds of events per night, repeated for years, weaken that muscular barrier. A 2025 prospective study found that consistent CPAP use significantly reduced GERD symptom scores through a direct effect on the lower esophageal sphincter rather than through better sleep alone.3National Center for Biotechnology Information. Impact of Continuous Positive Airway Pressure Therapy on Gastroesophageal Reflux Disease Symptoms Treating the primary condition improving the secondary one is strong evidence of a causal relationship, and a good nexus letter will say so.
Medications prescribed for conditions that travel with sleep apnea, including some drugs for anxiety and pain, can also relax the esophageal muscles and make reflux more likely. A nexus letter that addresses both mechanical and pharmacological pathways covers the full picture.
The Obesity Pathway
Some veterans develop GERD through an intermediate step: the sleep apnea contributes to weight gain, and the resulting obesity causes the reflux. Obesity cannot be service-connected on its own, but it can serve as a link in the chain. The theory requires evidence that your sleep apnea caused or worsened your obesity, that the obesity was a substantial factor in causing GERD, and that GERD would not have developed without that weight gain.4Department of Veterans Affairs. Board of Veterans’ Appeals Decision 23010030 This route needs more detailed medical evidence than a direct nexus, but it is available when your doctor can trace the chain.
How the VA Rates GERD Now
This is where outdated advice sends veterans off course. Before May 19, 2024, GERD had no dedicated code and was rated under Diagnostic Code 7346 for hiatal hernia based on epigastric distress, vomiting, and weight loss. That framework no longer governs new claims.
A final rule effective May 19, 2024 created Diagnostic Code 7206 specifically for GERD.5Federal Register. Schedule for Rating Disabilities: The Digestive System The criteria center on esophageal strictures and difficulty swallowing rather than general reflux symptoms:6eCFR. 38 CFR 4.114 – Schedule of Ratings, Digestive System
- 0 percent: Documented history of GERD without daily symptoms or need for daily medication.
- 10 percent: Documented esophageal stricture requiring daily medication to control difficulty swallowing, but otherwise no symptoms.
- 30 percent: Recurrent esophageal strictures causing difficulty swallowing that require dilation up to twice a year.
- 50 percent: Recurrent or stubborn strictures needing dilation three or more times yearly, steroid-assisted dilation at least once yearly, or esophageal stent placement.
- 80 percent: Recurrent or stubborn strictures with aspiration, malnutrition, or substantial weight loss, requiring surgical correction or a feeding tube.
Findings must be documented through barium swallow, CT scan, or upper endoscopy.6eCFR. 38 CFR 4.114 – Schedule of Ratings, Digestive System This is strict. Veterans who once received a 10 percent rating on occasional heartburn now need imaging or endoscopy showing esophageal damage to get a compensable rating under DC 7206.
If you filed your claim before May 19, 2024, the VA applies whichever criteria produce a higher rating, the old DC 7346 or the new DC 7206.7Department of Veterans Affairs. Board of Veterans’ Appeals Decision A25029438 For claims filed on or after that date, only the new criteria apply.
One boundary worth naming: if you already have another digestive rating, the VA does not always stack them. Federal regulations prohibit rating the same symptom under more than one code, and several digestive codes cannot be combined with each other; the VA assigns a single rating reflecting the worst overall disability picture and may bump it up one level if warranted.8eCFR. 38 CFR 4.14 – Avoidance of Pyramiding6eCFR. 38 CFR 4.114 – Schedule of Ratings, Digestive System If you already carry another digestive rating, ask your representative how the combination rule applies to your file before you assume the GERD percentage will simply add.
What Each Rating Pays
For a veteran with no dependents, the 2026 rates effective December 1, 2025 are:9Veterans Affairs. Current Veterans Disability Compensation Rates
- 0 percent: $0 per month, but service connection is established, which matters if the condition worsens.
- 10 percent: $180.42 per month.
- 30 percent: $552.47 per month.
- 50 percent: $1,132.90 per month.
Amounts increase if you have dependents. Your GERD rating combines with your sleep apnea rating and any other service-connected conditions using VA math, which applies each new rating to the remaining non-disabled portion rather than adding percentages directly. Even a 0 percent decision has value: it locks in service connection, keeps the door open for an increase later, and can qualify you for VA healthcare for the condition.
The Evidence You Need to Assemble
A Strong Nexus Letter
The nexus letter is the single most important document. It has to state that your GERD is “at least as likely as not” caused or aggravated by your service-connected sleep apnea. That phrase carries specific legal weight: a 50 percent or greater probability, which is the standard the VA uses. Language like “possibly related” or “could be connected” does not meet the threshold. The strongest letters cite the medical literature on intrathoracic pressure and esophageal sphincter dysfunction, reference your actual treatment history, and explain the mechanism as it applies to you rather than stating a conclusion.
A Completed Disability Benefits Questionnaire
A Disability Benefits Questionnaire gives your doctor a standardized form to document your GERD in the format raters use.10Department of Veterans Affairs. Public Disability Benefits Questionnaires Under DC 7206, your DBQ should include endoscopy or imaging results documenting any esophageal strictures, the frequency of dilation procedures, and whether you take daily medication for difficulty swallowing. Raters match DBQ findings directly to the schedule, and incomplete forms tend to produce lower ratings than the underlying condition would support.
VA Form 21-526EZ
VA Form 21-526EZ is the actual application.11Veterans Affairs. About VA Form 21-526EZ For a secondary claim, identify GERD as the condition you are claiming and name obstructive sleep apnea as the already service-connected disability that caused it. Precise dates and diagnostic detail prevent delays.
File an Intent to File First
Filing an Intent to File before your claim is complete can save you thousands in back pay. VA Form 21-0966 notifies the VA that you plan to submit a claim and locks in a potential effective date for retroactive benefits.12Veterans Affairs. Your Intent to File a VA Claim Submit your finished claim within one year and, if approved, your payments run from the Intent to File date rather than the date you submitted the completed application.
You can file it online, by phone, or by mail.13Veterans Affairs. About VA Form 21-0966 Only one Intent to File can be active at a time, the one-year clock starts the day you submit it, and once you file the completed claim the Intent to File becomes inactive. Miss the one-year deadline and your effective date resets to whenever you actually file. That lost time is lost money.
How and Where to File
Once your evidence is together, file online through VA.gov, which is fastest, or mail your forms to the Department of Veterans Affairs, Claims Intake Center, PO Box 4444, Janesville, WI 53547-4444.14Veterans Affairs. How to File a VA Disability Claim If you mail, use delivery confirmation.
After the VA receives your claim, it may schedule a Compensation and Pension exam if the existing evidence is not sufficient to decide. This is not automatic. If your file already contains a strong nexus letter, a completed DBQ with imaging, and consistent treatment records, the VA may decide without an additional exam under its Acceptable Clinical Evidence process.15Veterans Affairs. VA Claim Exam (C&P Exam) If you are scheduled for an exam, go. Missing it usually means a denial.
The average processing time was 76.6 days as of February 2026.16Veterans Affairs. The VA Claim Process After You File Your Claim Veterans who work with an accredited Veterans Service Organization and submit everything upfront through the Decision Ready Claims program can sometimes see decisions in 30 days or less.17U.S. Department of Veterans Affairs. Decision Ready Claims: 4 Steps to a Faster VA Claim Decision Track progress from your VA.gov dashboard.
If You Get Denied
A denial is not the end. You have one year from the date on the decision letter to use any of three review options:18Veterans Affairs. Higher-Level Reviews
- Supplemental Claim: submit new and relevant evidence that was not part of the original decision. This is the right path when your denial cited a weak nexus letter or missing documentation.19Veterans Affairs. VA Decision Reviews and Appeals
- Higher-Level Review: a senior reviewer examines the same evidence for errors. You cannot add new evidence, so this fits when you believe the rater misapplied the law or overlooked records already in the file.
- Board Appeal: a Veterans Law Judge reviews your case. It takes longer and lets you present testimony and, depending on the lane, submit additional evidence.
The most common reason secondary GERD claims fail is a weak or missing nexus opinion. If your denial says the evidence does not establish a link between sleep apnea and GERD, the strongest response is usually a Supplemental Claim with a more detailed nexus letter that answers the rater’s reasoning point by point, explains the intrathoracic pressure mechanism, cites the medical literature, and ties the analysis to your own treatment timeline.
