Sleep Apnea
Sleep apnea means your breathing repeatedly stops and starts all night, so you never reach deep, restorative sleep. It leaves you exhausted, foggy and at real cardiovascular risk — and a diagnosis that requires a CPAP machine is rated at 50%. It is badly under-diagnosed in women because the “middle-aged man” stereotype means they are rarely sent for a sleep study.
Everything is on this page, in plain English: what apnea actually is, why women get missed, what in your service causes it, exactly what each level pays, how the VA underrates it, and how to build a claim that holds up.
What Sleep Apnea Really Is
Sleep apnea is a condition in which your airway collapses or your brain briefly stops signaling you to breathe — dozens or even hundreds of times a night. Each pause drops your oxygen and jolts you out of deep sleep, usually without your ever knowing it happened. You wake up feeling like you never slept, because in the way that matters, you didn’t.
The phrase that governs your rating is requires a breathing assistance device. If your sleep study resulted in a prescription for a CPAP machine, you meet the criterion for the 50% level — full stop. That single fact is the difference between a 30% and a 50%, which is why getting the sleep study and the prescription documented matters so much.
“Requires a CPAP” — and why it decides your rating
What it means
A sleep study documented the apnea and your provider prescribed a breathing assistance device (CPAP/BiPAP) to treat it. That prescription is the trigger for 50%.
What the VA measures
Not how tired you feel — whether a device is required. 50% for a CPAP; 30% for daytime sleepiness without one; 100% for respiratory failure or a tracheostomy.
Why women get missed
The “middle-aged man” stereotype means women are rarely referred for a sleep study at all — so the diagnosis, and the rating that flows from it, never happens.
Why women get overlooked — and under-diagnosed
The textbook apnea patient is imagined as an older, heavyset man who snores. Women often don’t fit that picture — their symptoms show up as fatigue, insomnia, morning headaches and low mood rather than loud snoring — so a doctor is far more likely to hand them an antidepressant than a referral for a sleep study.
For veterans, apnea very often rides in behind another service-connected condition: PTSD that shreds sleep, weight gain from psychiatric medication, or airway damage from burn-pit exposure. Because the sleep study never gets ordered, the whole chain — diagnosis, CPAP, 50% rating — stops before it starts. Pushing for that sleep study is the single most important step.
By the Numbers
These figures come from sleep-medicine research and the VA’s own rating schedule. If you have been exhausted for years and no one ever ordered a sleep study, read them slowly.
50%
the rating for sleep apnea that requires a CPAP machine — the level most diagnosed veterans reach (DC 6847)
Often missed
women are far less likely to be referred for a sleep study because their symptoms don’t match the male stereotype
Secondary
apnea is very frequently connected as secondary to PTSD, medication weight gain, or sinus and airway conditions
100%
the rating when apnea progresses to chronic respiratory failure, cor pulmonale, or a tracheostomy
CPAP data
your machine’s compliance data is objective proof that supports and protects the 50% level
No deadline
there is no time limit to file — apnea rooted in service is still claimable years later
What in Your Service Causes It
Sleep apnea is very often secondary — caused or worsened by another service-connected condition. Naming the right connection is how the claim gets tied to your service and granted.
Secondary to PTSD
Trauma-driven sleep disruption and the underlying physiology of PTSD are recognized contributors to sleep apnea. When PTSD is already service-connected, apnea can be claimed as secondary to it — one of the most common and successful secondary connections women veterans have.
Weight change from medication
Weight gain caused by medications for service-connected conditions — antidepressants, mood stabilizers, steroids — can cause or worsen obstructive sleep apnea. That makes the apnea claimable as secondary to the condition those medications were treating.
Sinus & airway damage
Burn-pit and environmental exposure, a deviated septum, and chronic rhinitis narrow the upper airway and contribute to obstructive apnea. Airway damage that began with an in-service exposure is a direct route to service connection.
Disrupted sleep schedules
Watch rotations, shift work and irregular field sleep patterns are associated with the development of sleep-disordered breathing. Years of fractured, on-demand sleep during service can leave a lasting mark on how the body breathes at night.
What the VA Pays for Sleep Apnea
Sleep apnea is rated under 38 CFR §4.97, Diagnostic Code 6847. Here is exactly what each level requires, in plain English — the whole schedule turns on whether a breathing device is required.
Chronic respiratory failure with carbon-dioxide retention, or cor pulmonale (right-heart strain), or the need for a tracheostomy. This is the most severe presentation.
Requires the use of a breathing assistance device such as a CPAP machine. This is the level most veterans reach — if a sleep study prescribed a CPAP, this is your criterion. (DC 6847)
Persistent daytime sleepiness (hypersomnolence) without the need for a breathing device.
Diagnosed by sleep study but currently asymptomatic. Still worth establishing — it locks in service connection you can build on if it worsens.
Source: 38 CFR §4.97, Diagnostic Code 6847. Every percentage here is a starting point set by federal regulation, not a promise — your actual rating depends on your sleep study and records. An accredited representative can confirm exactly what fits your case.
A 50% secondary rating can transform your combined total
Because apnea is so often secondary to PTSD or another condition, a 50% apnea rating frequently stacks on top of ratings you already have — and 50% combines powerfully. If your service-connected conditions together make steady work impossible, ask about TDIU to be paid at the 100% rate.

How the VA Quietly Underrates Sleep Apnea
Apnea claims are frequently denied or lowballed on a technicality — usually the missing link back to service. Here is how it happens:
- A grant of the diagnosis but a denial of service connection, because no one documented the in-service symptom or secondary link
- A secondary claim to PTSD refused for lack of a clear medical nexus opinion
- A rating dropped to 30% by arguing the CPAP is “optional” rather than required
- A sleep study never ordered in the first place, so the whole claim stalls before it begins
This is where an accredited representative earns their place — securing the nexus opinion, framing the secondary connection correctly, and making sure the CPAP prescription is squarely in the record.
Secondary Claims — The Connections Most Women Miss
Sleep apnea sits at the center of a web of connections. It is often caused by another service-connected condition — and left untreated, it causes new ones. Each recognized link is a separate rating you may be missing.
Apnea caused by something else
If any of these is already service-connected, your apnea can often be connected as secondary to it:
PTSD, depression & anxiety
Trauma physiology and disrupted sleep are recognized contributors to apnea.
Weight gain from medication
Meds for service-connected conditions can drive the weight change behind apnea.
Rhinitis / sinusitis / deviated septum
Airway narrowing from exposure or injury contributes to obstruction.
GERD
Acid reflux is commonly linked with and aggravates obstructive apnea.
Conditions your apnea can cause
Once apnea is service-connected, these can be claimed as secondary to it:
Hypertension & heart disease
Untreated apnea strains the cardiovascular system and can cause new ratable conditions.
Depression & cognitive problems
Chronic exhaustion and oxygen dips worsen mood and memory.
Worsened migraines
Poor-quality sleep is a powerful migraine trigger and can aggravate a headache condition.
A secondary claim needs a diagnosis plus a medical opinion (“nexus”) saying the link is at least as likely as not. This is one of the highest-value things an accredited agent helps build.
Building a Sleep Apnea Claim That Wins
An apnea claim is won on the sleep study and the connection to service — not on how tired you have felt for years. Here is what a strong one is built from.
Every claim stands on three legs
A sleep study diagnosis
A formal sleep study confirming apnea — and, ideally, a prescription for a CPAP, which establishes the 50% criterion.
An in-service link
In-service symptoms (documented fatigue, snoring, witnessed pauses) or a secondary link to PTSD, medication weight gain, or a sinus/airway condition.
A nexus
A medical opinion stating the apnea is at least as likely as not related to service or to the primary service-connected condition.
Document the sleep problem — and get the study ordered
The single most important move is getting a sleep study on the record. Support it by writing down:
- Daytime exhaustion, morning headaches and difficulty concentrating
- Anything a partner has noticed — snoring, gasping, pauses in breathing
- When the sleep problems began in relation to your service or PTSD
- Your CPAP compliance data once you have a machine
What to expect at the C&P exam
The examiner works from the Sleep Apnea DBQ and will review your sleep study and treatment. Three things protect your rating:
Bring the sleep study
The diagnosis and the CPAP prescription are the objective proof of the 50% criterion — make sure they are in front of the examiner.
Describe the daytime toll
Exhaustion, fog, and how it affects your driving, work and family — not just how you sleep, but how the lack of sleep hits your life.
Name the connection
State plainly whether this is secondary to PTSD, medication or a sinus condition — do not leave the examiner to guess.
When you are ready to file
File on VA Form 21-526EZ, list sleep apnea and any primary condition it is secondary to, and attach your sleep study and CPAP records. You can also open the disability calculator to see how a 50% apnea rating would combine with the rest of your conditions.
Your Rights — Know Them Before You File
The system is easier to face when you know the rules are on your side. These protections apply to your sleep apnea claim from the moment you start.
You never pay a fee just to file. A VA-accredited representative can help you at no upfront cost — anyone demanding money up front to "start" your claim is a red flag.
The VA has a legal Duty to Assist — it must help you gather your service and medical records, and must tell you what evidence is still missing BEFORE it issues a denial.
You have the right to request a female provider and a trauma-informed clinician for any exam connected to your claim.
You have the right to file for every condition you live with — including secondary conditions your service-connected condition caused or made worse.
A single low rating is not the end of the road. You have the right to appeal, to submit new evidence, and to be re-evaluated as your condition changes.
If your conditions together keep you from holding steady, gainful work, you have the right to be considered for TDIU — paid at the 100% rate even if no single condition reaches 100%.
Questions Women Ask About Sleep Apnea Claims
Straight answers to the questions that stop women from filing — or from claiming everything they are owed.
If I use a CPAP machine, what rating should I expect?
When sleep apnea requires the use of a breathing assistance device such as a CPAP machine, the condition is rated at 50 percent. That is written into the rating criteria. If you are prescribed a CPAP but were rated lower, that is one of the clearest signs a decision was wrong and should be reviewed.
Can sleep apnea be secondary to my other service-connected conditions?
Frequently, yes. Sleep apnea is often service-connected as secondary to PTSD, to weight gain driven by a service-connected condition or medication, or to chronic sinus and nasal conditions. A secondary claim only needs a medical opinion linking the two — you do not have to prove the apnea itself started in service.
I was never given a sleep study while I was in. Can I still win?
Yes. You do not need an in-service sleep study to be service-connected. Buddy statements from people who witnessed your loud snoring, choking or gasping and daytime exhaustion during service — combined with a current diagnosis and a nexus opinion — can carry the claim. Lack of a study on active duty is not a bar.
How common is the 50 percent rating?
Very. Because the criteria tie the 50 percent level directly to needing a CPAP or similar device, the majority of veterans who are prescribed one and properly rated land at 50 percent. Getting there depends on the evidence being framed correctly — which is exactly what an accredited review checks.
When You Are Ready to File
Before you file anything, talk to an accredited agent first — it is free. A claim is won or lost on how it is built: the diagnosis on record, the right in-service connection, and whether every condition and secondary is captured. Once a claim is submitted it is much harder to fix than to get right the first time. There is no fee to have an accredited claims agent (#45147) review your situation and tell you honestly whether and how we can help.
