Last updated: October 2026
You wake up tired no matter how long you were in bed. Your spouse says you snore like a chainsaw and sometimes stop breathing. Maybe you already sleep with a CPAP (continuous positive airway pressure, a machine that keeps your airway open while you sleep) mask every night. Now you're wondering whether VA will connect any of this to your service, especially since nobody tested you for sleep apnea while you were in.
VA does rate sleep apnea, and veterans win these claims. They are also among the most evidence-heavy claims you can file, and most of them succeed or fail on a few specific documents. This guide covers how VA defines and rates sleep apnea, the realistic paths to service connection, the evidence that matters, what happens at the exam, why claims get denied, related secondary conditions, and when TDIU (Total Disability based on Individual Unemployability, a VA benefit that pays at the 100% rate when service-connected conditions prevent substantially gainful work) might apply.
I'm not an attorney or a VSO (Veterans Service Organization, a group with VA-accredited representatives who help with claims for free), and this post isn't legal advice. It's general education based on VA's published rules and my own experience.
Sleep Apnea at a Glance
Diagnostic code: 38 CFR 4.97, Diagnostic Code 6847, "Sleep Apnea Syndromes (Obstructive, Central, Mixed)."
Rating levels: 0%, 30%, 50%, and 100%.
Common paths to service connection: Secondary, meaning an already service-connected condition such as PTSD caused or worsened the sleep apnea. This is the most common path. Direct, meaning the sleep apnea started in service. This path is harder without an in-service sleep study.
Key evidence: A sleep study confirming the diagnosis, records of your CPAP use, a nexus letter (a medical opinion linking your condition to service or to another service-connected condition), and treatment records for any condition you're claiming it's secondary to.
Main exam: A C&P (Compensation and Pension) exam, the medical appointment VA orders to decide your claim. The examiner uses VA's Sleep Apnea Disability Benefits Questionnaire (DBQ), a standard form for recording your diagnosis and severity.
Official criteria: 38 CFR 4.97 on eCFR.
Rule change status: VA has proposed changing how sleep apnea is rated, but that change isn't in effect. Claims today are rated under the current 0/30/50/100 levels. The rating section below explains this.
How the VA Defines Sleep Apnea
VA treats sleep apnea as a respiratory condition. It sits in the part of the rating schedule that covers the respiratory system, alongside conditions like asthma and COPD.
Sleep apnea means your breathing repeatedly stops or becomes very shallow while you sleep. The diagnostic code covers three types:
Obstructive sleep apnea (OSA): Your airway physically collapses or gets blocked during sleep. This is the most common type.
Central sleep apnea: Your airway stays open, but your brain doesn't consistently send the signal to breathe.
Mixed sleep apnea: A combination of both.
VA rates all three types under the same code and the same criteria, so the type you have doesn't change the rating scale.
The diagnosis is where sleep apnea differs from conditions like migraines or PTSD. Those can be diagnosed from your symptoms and a provider's clinical judgment. Sleep apnea needs objective testing. Whether you're filing directly or as secondary to another condition, VA requires a sleep study, also called a polysomnography, to confirm the diagnosis. That's a monitored study that records how often your breathing stops, your oxygen levels, and your sleep stages. Telling a doctor you snore and feel exhausted is a good start, but it won't confirm the diagnosis for VA purposes.
Some veterans are diagnosed with a home sleep test instead of an overnight lab study. Both of my sleep apnea tests were done at home. If yours came from a home test and you aren't sure it's enough, ask your doctor whether a full in-lab study makes sense before you file.
Your next step: find your sleep study report. If you've never had one, that's the first appointment to make.
How the VA Rates Sleep Apnea
VA assigns one of four levels based on how the condition affects you and what treatment it requires:
| Rating | What it generally means |
|---|---|
| 100% | Chronic respiratory failure with carbon dioxide retention, or cor pulmonale (heart strain caused by lung or breathing problems), or you require a tracheostomy (a surgical airway opening in the neck) |
| 50% | You require a breathing assistance device, such as a CPAP machine |
| 30% | Persistent daytime hypersomnolence, meaning ongoing excessive sleepiness during the day |
| 0% | No symptoms, but a documented sleep-disordered breathing diagnosis |
Read the full rating criteria on eCFR. To see what each level pays, use my VA disability calculator.
Under the current rules, the 50% level turns on one thing: whether you require a breathing assistance device. It doesn't ask how sleepy you are or how many times an hour you stop breathing. The key word is "requires," so your records should show a provider prescribed the device because you need it. A CPAP you bought on your own without a prescription won't carry the same weight.
The 0% level still matters. A 0% rating means VA agrees the condition is service-connected but isn't paying compensation for it yet. If your condition gets worse and you later need a CPAP, you can ask for an increase without having to prove service connection again.
The Proposed Rule Change
You may have heard that VA is "getting rid of" the 50% CPAP rating. Here's where that comes from. In February 2022, VA proposed updating parts of the rating schedule, including the respiratory section. According to reporting on the proposal, the change would rate sleep apnea on how well treatment works instead of whether you use a device, and would drop the 30% level. Reporting also describes a supplemental proposal in 2024 that revised parts of the package.
That rule isn't final and has no effective date. A proposed rule isn't law. Every claim filed today is rated under the current 0/30/50/100 criteria in the table above.
If you already have a sleep apnea rating, the law protects you if a change is ever finalized. Under 38 U.S.C. 1155, a change to the rating schedule can't reduce a rating that was in effect on the date the change takes effect unless your condition has actually improved.
My takeaway: if you have sleep apnea that you believe is connected to service, don't sit on it out of fear of the rule, and don't rush a weak claim out of panic either. File when your evidence is ready.
Getting Sleep Apnea Service Connected
To service connect a condition, VA generally needs three things: a current diagnosis, something that happened during service or a service-connected condition that caused it, and a nexus. A nexus is the medical link between your current condition and your service or another service-connected condition.
Direct Service Connection
Direct service connection under 38 CFR 3.303 means your sleep apnea began during service or was caused by it. This is the hardest path for sleep apnea, because sleep studies were rarely done in service. Without an in-service diagnosis, you're asking VA to accept that symptoms you had back then were sleep apnea that nobody tested for.
It isn't impossible, though. Evidence for a direct claim can include:
Service treatment records showing complaints of fatigue, poor sleep, or snoring.
Lay evidence, meaning statements from you or people who observed your symptoms. A roommate or bunkmate who heard you snoring and gasping or noticed you stop breathing at night is exactly this kind of witness.
A medical opinion explaining why those in-service symptoms were early signs of the condition you were later diagnosed with.
VA can't reject lay evidence just because there's no medical record from the same time to back it up (Buchanan v. Nicholson, 2006). That doesn't make lay statements automatically enough, but it means a bunkmate's account counts.
Secondary Service Connection
Secondary service connection under 38 CFR 3.310 covers a condition that was caused by an already service-connected condition, or aggravated by one. Aggravated means made worse beyond its natural progression. You don't have to prove the service-connected condition caused your sleep apnea from scratch. Showing that it made the sleep apnea worse is a complete path on its own.
This is the path most sleep apnea claims take. Since most of us were never tested in service, tying sleep apnea to a condition VA has already accepted is usually more realistic than proving it started on active duty. PTSD is the most common pairing. If PTSD is part of your claim picture, my PTSD VA disability guide covers how that condition gets service-connected and rated.
As an example, a doctor's nexus letter for sleep apnea secondary to PTSD might explain how PTSD-related nighttime hyperarousal and disrupted sleep, or weight gain from psychiatric medication, contributed to the development or worsening of the veteran's sleep apnea. The letter has to explain the mechanism for your specific case. Pointing out that both conditions exist isn't enough.
A strong secondary claim usually has three pieces:
A sleep study confirming the sleep apnea diagnosis.
An already service-connected condition that you're linking it to.
A nexus letter explaining how that condition caused or aggravated your sleep apnea.
Presumptive Service Connection
Sleep apnea doesn't have a presumptive category of its own, and the PACT Act doesn't list it as a presumptive respiratory condition. However, the PACT Act, the 2022 toxic exposure law, does make chronic rhinitis and chronic sinusitis presumptive for veterans who served in covered locations. If one of those is service-connected for you, it could become the starting point for a secondary claim.
Evidence That Strengthens Your Claim
Sleep apnea claims live or die on documents. Here's what to gather:
Your sleep study report. This is the anchor of the entire claim. Make sure VA has the full report, not just a line in a treatment note saying you have sleep apnea.
Proof that you require a device. Your CPAP prescription, plus usage data showing you actually use it. Many machines track nightly use, and your sleep clinic or equipment supplier can usually print a compliance report. Consistent use backs up the claim that you need the device. It also helps if VA reviews your rating later.
A nexus letter. The legal standard is whether your sleep apnea is "at least as likely as not" related to service or to your service-connected condition. That means a 50% chance or better. The strongest letters show the doctor reviewed your records, explain the medical reasoning in plain terms, and address other risk factors instead of ignoring them. When the evidence for and against is evenly balanced, VA must resolve the doubt in your favor under 38 CFR 3.102.
Treatment records for both conditions. For a secondary claim, VA wants to see the timeline: when the service-connected condition started, when sleep symptoms appeared, and how they've progressed together.
Lay statements. Your spouse or partner is often the best witness you have. They're the one who hears the snoring, watches you stop breathing, and sees you nod off on the couch at 7 p.m. Statements like these go on VA Form 21-10210, the lay/witness statement form. Your own statement can describe when your sleep problems started, how they changed, and how daytime exhaustion affects your work and home life.
Your claims file. Old notes about fatigue or poor sleep can be buried in records you've forgotten about. Requesting your C-file lets you see everything VA has.
My Evidence Organizer includes a secondary conditions worksheet that helps keep a sleep study, nexus letter, and treatment timeline organized in one place.
What to Expect at Your C&P Exam
For sleep apnea, the C&P exam usually focuses on confirming the diagnosis, documenting severity, and, for secondary claims, giving an opinion on whether your service-connected condition caused or worsened it. The examiner fills out the Sleep Apnea DBQ. Expect questions about:
Your sleep study: when and where it was done, and what it found.
Treatment: whether you use a CPAP or other device, and whether a provider prescribed it.
Daytime symptoms: sleepiness, fatigue, trouble concentrating, and dozing off during the day.
Daily impact: how the condition affects your work, driving, and home life.
Sleep apnea exams are often fairly short and may involve little physical examination. Don't take that as a bad sign. The examiner is mostly confirming what's in your records, which is why the records need to be complete before you walk in.
Before your exam, make sure VA has your sleep study, your CPAP prescription, and a recent compliance report. Bring copies anyway. Keep a short log of daytime sleepiness for a week or two so you can give specific examples instead of saying "I'm tired a lot." If you have a private nexus letter, submit it before the exam date so the examiner can review it. My C&P Exam Prep Workbook includes a Sleep Apnea insert along with a daily symptom log and a one-page exam summary for organizing exactly this kind of information.
You might not need an in-person exam at all. If your file already has enough medical evidence, VA can decide through the Acceptable Clinical Evidence (ACE) process, where a reviewer evaluates your records without seeing you. For a full walkthrough of the appointment itself, see my guide on what to expect at a C&P exam.
Common Reasons Sleep Apnea Claims Are Denied
This was the hardest claim for me to win. My obstructive sleep apnea is service-connected secondary to PTSD, and getting there took over two years, multiple specialists, and three denials. It finally ended with a Higher-Level Review, where a senior reviewer looks at the same evidence for errors. That review found a duty-to-assist error. The duty to assist is VA's legal obligation to help you develop your claim, including getting records and adequate exams. Each denial taught me something about what VA needed to see, and these are the patterns behind most sleep apnea denials:
No in-service diagnosis on a direct claim. If you file directly and your service records show nothing about sleep, VA often denies. Switching to a secondary theory, if one fits, is frequently the better move.
No nexus, or a nexus that doesn't explain anything. VA may agree you have both PTSD and sleep apnea and still deny, because nobody explained how one caused or worsened the other. A one-line opinion rarely holds up.
Blaming weight, age, or anatomy. Examiners and raters (the VA employees who decide your claim) often attribute sleep apnea to body weight, neck size, or getting older. A nexus letter that addresses those risk factors directly holds up much better than one that ignores them.
Treating the CPAP as proof. A CPAP prescription confirms you have the condition and supports the 50% level. It doesn't establish service connection. You still need the in-service event or service-connected condition, plus the nexus.
If you're denied, match your next step to the reason in your decision letter:
| Option | Best When | Form |
|---|---|---|
| Supplemental Claim | You have new and relevant evidence, such as a sleep study or nexus letter | VA Form 20-0995 |
| Higher-Level Review | VA had the right evidence but made an error, such as a duty-to-assist error | VA Form 20-0996 |
| Board Appeal | You want a Veterans Law Judge to review your case | VA Form 10182 |
VA's decision reviews page explains each option. Filing within one year of your decision letter protects your effective date.
Secondary Conditions Linked to Sleep Apnea
Secondary connection runs both ways with sleep apnea.
Conditions sleep apnea is often claimed secondary to:
PTSD, the most common pairing.
Other mental health conditions, such as depression or anxiety.
Chronic rhinitis or sinusitis, which can affect breathing through the nose.
Deviated septum, especially from an in-service nose injury.
GERD, where acid reflux is argued to contribute to airway problems at night.
Asthma.
Weight gain tied to a service-connected condition, such as from psychiatric medication or limited activity after an injury. VA doesn't treat weight gain or obesity as a disability on its own, but it can be an "intermediate step" between a service-connected condition and sleep apnea.
Conditions sometimes claimed secondary to sleep apnea:
Hypertension and heart disease, on the theory that repeated drops in oxygen during the night strain the cardiovascular system.
GERD.
Depression.
A word of caution here. You'll find websites listing a dozen or more conditions "automatically" linked to sleep apnea. None of these are presumptive. VA doesn't grant any of them just because you have service-connected sleep apnea. Each one is its own claim, and each needs its own diagnosis and its own nexus opinion explaining how the connection works for you.
My advice is to claim only what you can support with a doctor's reasoning, and to start with the connection your treating providers already see.
When TDIU May Apply
TDIU lets VA pay you at the 100% rate when service-connected conditions keep you from holding a substantially gainful job, even if your combined rating is lower. Substantially gainful generally means more than marginal employment. Earned income at or below the poverty threshold for one person usually counts as marginal.
Sleep apnea's core symptoms matter here. Daytime sleepiness, fatigue, and trouble concentrating are the same symptoms the examiner records on the DBQ, and they can make jobs that involve driving, operating equipment, or sustained focus unsafe or unworkable.
Schedular TDIU (TDIU granted because you meet VA's set rating thresholds) under 38 CFR 4.16(a) requires either one service-connected condition rated at least 60%, or two or more conditions with a combined rating of at least 70% and one rated at least 40%. Sleep apnea alone can't meet the single-condition threshold short of 100%, since the next level down is 50%. In practice, sleep apnea usually figures into TDIU alongside other ratings. For example, sleep apnea at 50% and PTSD at 50% combine to 80% under VA's combined ratings table rather than simple addition, and with at least one condition at 40% or higher, that meets the schedular threshold.
If you don't meet those numbers but still can't keep a job because of your service-connected conditions, VA can refer your claim for extraschedular TDIU under 4.16(b), meaning TDIU considered outside the standard rating thresholds, case by case. Either way, evidence about how your conditions affect your work carries the claim, and an opinion from a vocational expert can strengthen it.
You apply with VA Form 21-8940. My TDIU eligibility guide walks through the full process.
Conclusion
Sleep apnea claims are winnable, but they don't reward shortcuts. VA wants an objective diagnosis, a clear explanation of how the condition connects to your service or a service-connected condition, and records showing what treatment you need. When a piece is missing, the claim usually stalls until you supply it.
If you snore loudly, wake up exhausted, or have a service-connected condition like PTSD that wrecks your sleep, start with the sleep study. Talk to your doctor about getting one scheduled now, since nearly every other piece of this claim depends on that single report. An accredited VSO can help you request records, develop the nexus question, and choose the right review option if you're denied, at no cost. You can find an accredited representative on VA.gov.
