How the VA rates sleep apnea
The VA rates sleep apnea under Diagnostic Code 6847 (sleep apnea syndromes) in 38 CFR Part 4. Unlike many conditions, the sleep apnea rating is not based on range of motion or lab numbers alone. It is driven almost entirely by your symptoms and whether a doctor has prescribed a breathing assistance device such as a CPAP machine.
- 0 percent - Asymptomatic but with documented sleep disorder breathing.
- 30 percent - Persistent daytime hypersomnolence (excessive daytime sleepiness).
- 50 percent - Requires the use of a breathing assistance device such as a CPAP machine.
- 100 percent - Chronic respiratory failure with carbon dioxide retention, the need for a tracheostomy, or cor pulmonale (right-sided heart enlargement).
The jump from 30 to 50 percent is significant for most veterans. If your treating physician has prescribed a CPAP, BiPAP, or similar device and it is documented in your records, you generally meet the criteria for a 50 percent rating, even if the device controls your symptoms well.

Direct vs. secondary service connection
There are two main paths to service connection for sleep apnea, and choosing the right one matters.
Direct service connection
Direct service connection means your sleep apnea began in or was caused by your active-duty service. This is easiest to prove when your service treatment records document symptoms like loud snoring, witnessed pauses in breathing, or chronic fatigue, or when you were diagnosed while still in uniform. Buddy statements from people who served with you and noticed your snoring or gasping during sleep can help fill gaps in the record.
Secondary service connection
Many veterans develop or worsen sleep apnea because of another service-connected condition. Common secondary theories include:
- Secondary to PTSD or mental health conditions. A growing body of medical literature links PTSD and depression to sleep-disordered breathing. If you already have a service-connected mental health condition, apnea may be claimed as secondary. Learn more about PTSD VA disability claims.
- Secondary to sinusitis or rhinitis. Chronic nasal and sinus obstruction can contribute to or aggravate obstructive sleep apnea.
- Secondary to weight gain from medication. If a service-connected condition or its medication caused significant weight gain, and that weight gain contributed to your apnea, this can support a secondary claim.
Secondary claims require a medical nexus opinion connecting the two conditions. If you are unsure which path fits, our mental health disability and claims team can help you evaluate your options.
Sleep studies and diagnostic evidence
The VA will almost always require an official sleep study to confirm a diagnosis of obstructive sleep apnea. There are two common types:
- In-lab polysomnography. An overnight study in a sleep clinic that measures your apnea-hypopnea index (AHI), oxygen levels, and other data. This is generally considered the gold standard.
- Home sleep apnea testing. A portable study you complete at home. It is often accepted but can be viewed as less definitive in some cases.
A diagnosis from a sleep study is the foundation of your claim. Self-reported snoring or fatigue, without a confirmatory study, is rarely enough. If you were diagnosed years ago, make sure the VA has a copy of the actual sleep study report, not just a note that mentions apnea.
Nexus evidence: connecting apnea to service
A nexus is the medical link between your current diagnosis and your service or another service-connected condition. For sleep apnea, strong nexus evidence usually includes:
- A written medical opinion from a physician stating that it is at least as likely as not that your sleep apnea is related to service or to a service-connected condition.
- A clear explanation of the medical reasoning, citing your records and relevant medical literature.
- Contemporaneous evidence such as service treatment records, buddy statements, or a spouse's lay statement describing symptoms during and after service.
The phrase "at least as likely as not" reflects the roughly 50 percent or greater standard the VA uses. A nexus letter that simply says the conditions are "possibly related" is often not enough. A well-supported opinion that explains the why carries far more weight.
Why sleep apnea claims get denied
Sleep apnea is denied more often than veterans expect. The most common reasons include:
- No in-service event or symptoms. When apnea is first diagnosed years after separation with nothing in the service records, the VA may find no connection to service.
- Missing nexus opinion. Without a medical opinion linking apnea to service or a secondary condition, the claim often fails.
- Weak secondary evidence. Claiming apnea as secondary to PTSD or weight gain without a supporting medical rationale frequently draws a denial.
- No confirmatory sleep study. The VA may deny claims where the diagnosis is not backed by a formal study.
A denial is not the end of the road. Many sleep apnea denials are overturned with a stronger nexus opinion or a corrected secondary theory. Learn about your options after a denied VA claim or how to appeal a VA decision under the AMA.

Frequently Asked Questions
Do I automatically get 50 percent for using a CPAP machine?
If a doctor has prescribed a CPAP or similar breathing assistance device for your diagnosed sleep apnea, you generally meet the criteria for a 50 percent rating under Diagnostic Code 6847, even if the device controls your symptoms. The prescription and use of the device must be documented in your medical records.
Can I get sleep apnea service-connected secondary to PTSD?
Yes. Sleep apnea can be claimed as secondary to a service-connected mental health condition such as PTSD. You will need a medical nexus opinion explaining how your PTSD caused or aggravated the apnea. This is general information, not legal advice about your specific claim.
Do I need a sleep study to win my claim?
In most cases, yes. The VA typically requires a formal sleep study, either in-lab polysomnography or an accepted home sleep test, to confirm the diagnosis. Make sure the VA has the actual study report on file, not just a note mentioning apnea.
My sleep apnea claim was denied. Can I still win?
Often, yes. Many denials result from a missing nexus opinion or a weak secondary theory that can be corrected on appeal. You may file a Higher-Level Review, a Supplemental Claim with new evidence, or an appeal to the Board of Veterans' Appeals under the AMA.
