How to File a VA Disability Claim for Sleep Apnea

To file a VA disability claim for sleep apnea, you need three things: a formal diagnosis from a sleep study, medical evidence linking the condition to your military service, and a completed VA Form 21-526EZ submitted to the VA. Most veterans who use a CPAP machine receive a 50% rating, which pays $1,132.90 per month in 2026. Claims were averaging about 132 days to process as of June 2025, and a complete evidence package at submission is the single biggest factor in getting a decision quickly and in your favor.1VA News.

What You Need Before You File

Three pieces of evidence form the backbone of every sleep apnea claim: a sleep study, service and medical records, and a nexus letter. Assemble these first, then file.

A Sleep Study With AHI Data

Every claim requires a formal diagnosis from a polysomnography (sleep study). This overnight test measures your breathing, blood oxygen, brain activity, and heart rate while you sleep, and produces an Apnea-Hypopnea Index (AHI) score that counts how often your breathing stops or slows per hour.

You can get the study at a VA medical facility at no cost, or use a private provider. A private sleep study typically runs $700 to $1,600 or more without insurance. If you go private, confirm the clinic will provide a full diagnostic report with AHI data. A doctor’s letter alone won’t do; the VA needs the objective measurement.

Your diagnosis should specify obstructive, central, or mixed sleep apnea. All three fall under Diagnostic Code 6847, but the specific type belongs in your records and on your application.2eCFR. 38 CFR 4.97 – Schedule of Ratings, Respiratory System

A Nexus Letter

The nexus letter is a written medical opinion from a doctor stating that your sleep apnea is connected to your military service. This is where most claims are won or lost.

The doctor must use specific language. The phrase the VA looks for is “at least as likely as not” that the condition is related to your service. That wording meets the VA’s evidentiary threshold. Weaker phrasing like “it’s possible” or “it could be related” typically results in denial.

A strong nexus letter does more than state a conclusion. The doctor should walk through the medical reasoning, reference specific entries in your service treatment records, and ideally cite relevant medical literature. If your records show documented complaints of snoring, gasping during sleep, or chronic fatigue on active duty, the letter should tie those entries directly to your current diagnosis.

Service Records, Medical History, and Buddy Statements

Your service treatment records are the foundation for proving symptoms started during active duty. Look for anything mentioning sleep problems, snoring, daytime drowsiness, chronic headaches, or fatigue. Entries that don’t use the words “sleep apnea” still help if they describe symptoms consistent with it.

Private medical records after separation fill the gap between discharge and diagnosis. A continuous treatment history strengthens your case. A multi-year gap between discharge and diagnosis invites closer scrutiny of the nexus, so the letter needs to address it head-on.

Buddy statements are surprisingly powerful. A spouse or roommate who watched you snore, gasp, or choke during sleep gives the VA firsthand observations that clinical records can’t provide. Fellow service members who bunked near you and remember your sleep problems can submit statements too. Use VA Form 21-10210 for lay witness statements.3Veterans Affairs. About VA Form 21-4138

Connecting Sleep Apnea to Your Service

Sleep apnea often develops or worsens years after discharge, which makes the service connection the hardest part of the claim. You have two paths.

Direct Service Connection

Direct connection means showing that symptoms began during active duty and continued to the present. Documented in-service complaints of snoring, choking during sleep, or persistent daytime fatigue support this path. The nexus letter connects those documented symptoms to your current diagnosis.

Secondary Service Connection

If you can’t show the condition started in service, you may still qualify if a condition you’re already service-connected for caused or aggravated your sleep apnea. This is called secondary service connection, and it’s one of the most common paths for sleep apnea approvals.

PTSD is the most frequently cited primary condition. Multiple Board of Veterans’ Appeals decisions have recognized the connection between PTSD and sleep-disordered breathing, based on the theory that PTSD disrupts sleep architecture, promotes disordered breathing, and causes neurophysiological changes that contribute to sleep apnea.4U.S. Department of Veterans Affairs. Board of Veterans’ Appeals Decision A21018009

Chronic sinusitis and allergic rhinitis are another proven pathway. The Board has granted service connection for sleep apnea secondary to these conditions based on the physiological link between chronic nasal inflammation and upper airway obstruction during sleep.5U.S. Department of Veterans Affairs. Board of Veterans’ Appeals Decision 22017118

Weight gain from a service-connected injury can link to sleep apnea through a more complicated path. The VA doesn’t recognize obesity itself as a disability, so you can’t be service-connected for being overweight. Under the legal theory from Walsh v. Wilkie, however, obesity can serve as an intermediate step. You’d need to show that a service-connected disability caused your weight gain, that the weight gain substantially contributed to developing sleep apnea, and that the sleep apnea wouldn’t have occurred without the obesity. A knee or back injury that severely limited physical activity is the typical example.

For any secondary claim, the nexus letter must specifically address the connection between the primary service-connected condition and your sleep apnea, not just between your service and the sleep apnea directly.

One boundary to know: sleep apnea is not on the PACT Act’s list of presumptive conditions for burn pit or toxic exposure. You can still file a direct or secondary claim if you were exposed, but you won’t get the streamlined presumptive process.

Filing VA Form 21-526EZ

VA Form 21-526EZ is the official application for disability compensation.6Veterans Affairs. About VA Form 21-526EZ It asks for your personal information, military service history including branch and active duty dates, and the specific disability you’re claiming. When you describe the condition, use the exact term from your diagnosis, such as “obstructive sleep apnea,” rather than something vague like “breathing problems.” Precision keeps the claim from getting misrouted.

File an Intent to File First

If your evidence isn’t ready, submit an Intent to File (VA Form 21-0966) before anything else. This sets a potential start date for your benefits and gives you a full year to gather everything you need.7Veterans Affairs. Your Intent to File a VA Claim If the VA later approves your claim, retroactive payments can go back to the Intent to File date rather than the date you submitted the completed application.8Veterans Affairs. Intent to File Form 21-0966

If you start your application online through VA.gov, clicking the button to begin automatically registers your Intent to File.9U.S. Department of Veterans Affairs. File for Disability Compensation With VA Form 21-526EZ Your effective date is locked in even if you don’t finish in one sitting. Don’t let the one-year window expire, though. If it does, the effective date resets.

Use the Fully Developed Claims Program When You’re Ready

The VA processes claims faster when you submit all evidence upfront through the Fully Developed Claims (FDC) program.10Veterans Affairs. Fully Developed Claims Program To qualify, include your completed 21-526EZ, all supporting medical records and statements, and a certification that no additional evidence exists. You must also attend any VA exam the agency schedules.

The tradeoff is strict. If you submit additional evidence after filing, the VA pulls your claim out of the FDC track and processes it as a standard claim. Only use this option when your evidence package is genuinely complete.

Three Ways to Submit

  • Online: The VA.gov portal lets you upload the completed 21-526EZ and all supporting documents, timestamps everything, and generates a confirmation receipt. It’s the most reliable option.9U.S. Department of Veterans Affairs. File for Disability Compensation With VA Form 21-526EZ
  • By mail: Send the form and supporting documents to Department of Veterans Affairs, Claims Intake Center, PO Box 4444, Janesville, WI 53547-4444. Use certified mail so you have proof of receipt.11Veterans Affairs. How to File a VA Disability Claim
  • In person: Bring your paperwork to a VA regional office.

What Happens After You File

Once the VA receives your application, federal law requires the agency to help you gather any remaining evidence needed to decide your claim. Under 38 U.S.C. § 5103A, the VA must make reasonable efforts to obtain supporting evidence, including scheduling a medical exam when one is necessary.12Office of the Law Revision Counsel. 38 USC 5103A – Duty to Assist Claimants

The C&P Exam

For sleep apnea claims, the VA almost always schedules a Compensation and Pension (C&P) exam, conducted by a VA clinician or a third-party contractor. You’ll get a phone call or letter with appointment details. Don’t miss it. Failing to appear without rescheduling means the VA decides your claim on whatever is already in the file, and that rarely goes well.

During the exam, the provider completes the Sleep Apnea Disability Benefits Questionnaire (DBQ), which covers:13Veterans Benefits Administration. Sleep Apnea Disability Benefits Questionnaire

  • Your specific diagnosis and date of diagnosis
  • Whether you require a CPAP or other breathing assistance device
  • Current symptoms, including daytime sleepiness, respiratory failure, or carbon dioxide retention
  • Sleep study results and where the study was performed
  • How the condition affects your ability to work, with specific examples

The DBQ is public. Download it from the VA’s website before your appointment and review it so you know exactly what the examiner is documenting. If the examiner skips something on the form that applies to you, bring it up.

Timeline

The VA reported an average processing time of about 132 days for disability claims as of June 2025.1VA News. VA Processes More Than 2M Disability Claims in Record Time Fully developed claims generally move faster. Track your claim’s status through the VA.gov dashboard. The process ends with a rating decision letter explaining the percentage assigned and your monthly compensation.

What the Ratings Pay

The VA rates sleep apnea under Diagnostic Code 6847 at 38 C.F.R. § 4.97. There are four possible ratings:2eCFR. 38 CFR 4.97 – Schedule of Ratings, Respiratory System

  • 0%: Documented sleep-disordered breathing confirmed by a sleep study, but no current symptoms. No monthly pay, but the service-connected condition is established for future claims if symptoms worsen.
  • 30%: Persistent daytime sleepiness (hypersomnolence) that affects daily function. Pays $552.47 per month in 2026.
  • 50%: Requires a CPAP, BiPAP, or other breathing assistance device. This is where most sleep apnea claims land, and it pays $1,132.90 per month.
  • 100%: Chronic respiratory failure with carbon dioxide retention, cor pulmonale, or a required tracheostomy. Pays $3,938.58 per month and may qualify you for special monthly compensation.

Those figures are 2026 rates for a single veteran with no dependents. Payments rise if you have a spouse, children, or dependent parents, and the VA adjusts amounts annually for cost of living.

One rating limit matters here: the VA won’t give you separate ratings for sleep apnea and another respiratory condition like asthma or COPD. Under 38 C.F.R. § 4.96(a), respiratory conditions rated under Diagnostic Codes 6600 through 6847 can’t be combined. The VA assigns a single rating based on whichever condition causes the most disability.

If Your Claim Is Denied

A denial isn’t final. The VA offers three review options:14Veterans Affairs. VA Decision Reviews and Appeals

  • Supplemental Claim: File this when you have new, relevant evidence the VA hasn’t seen. A stronger nexus letter from a specialist or a new buddy statement qualifies. There’s no deadline, but earlier filing means earlier benefits if the outcome changes.15Veterans Affairs. Supplemental Claims
  • Higher-Level Review: A more senior VA reviewer re-examines the same evidence. You can’t add new evidence. Best when you believe the original reviewer misapplied the law or misread your records.
  • Board of Veterans’ Appeals: A Veterans Law Judge reviews your case. You can request a hearing, submit additional evidence, or ask for a review on the existing record. Takes the longest, provides the most thorough review.

The most common reason for sleep apnea denial is a weak or missing nexus letter. If that’s why you were denied, get a detailed opinion from a specialist who reviews your service records and medical history, then file a Supplemental Claim with the new opinion attached.

Get Free Help From an Accredited Representative

Before you file, consider bringing in a Veterans Service Organization. Accredited VSO representatives help with disability claims at no cost, ever.16Veterans Affairs. Get Help From a VA Accredited Representative or VSO The DAV, VFW, and American Legion have trained representatives who file these claims every day. They know what examiners look for, they can review your evidence package before submission, and they can catch weaknesses you might miss.

To formally appoint a VSO, complete VA Form 21-22.17Veterans Affairs. About VA Form 21-22 Both you and the representative sign it, then submit it online through AccessVA, by mail, or in person at a regional office. Once appointed, the VSO can access your VA records and communicate with the agency on your behalf. Accredited claims agents and attorneys are also available and typically charge a fee. For a first sleep apnea claim, a VSO is the most practical starting point.
