Sleep apnea is one of the most claimed conditions in the VA system, and the rules around it confuse a lot of veterans. Here's how the sleep apnea VA rating is built under Diagnostic Code 6847, why a CPAP prescription sits at the center of it, and what the proposed changes could mean.
Let's start with the single fact that drives most of these claims: under the current rating schedule, the sleep apnea VA rating is not based on how tired you feel — it's based largely on the treatment your condition requires. That's why a veteran who is prescribed a CPAP machine can reach the 50% level while a veteran with milder, untreated symptoms sits lower. Understanding that logic is the whole ballgame, so we'll walk through it plainly.
Sleep apnea (obstructive, central, or mixed) is rated under Diagnostic Code 6847 in the respiratory section of VA's rating schedule. There are four breakpoints, and there is nothing in between them — you land on one of these numbers:
| Rating | Current criteria (Diagnostic Code 6847) |
|---|---|
| 0% | Documented sleep-disordered breathing, but asymptomatic. |
| 30% | Persistent daytime hypersomnolence (chronic, excessive daytime sleepiness). |
| 50% | Requires the use of a breathing assistance device such as a CPAP machine. |
| 100% | Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires a tracheostomy. |
Notice the jump. There is no 10%, 20%, or 40% for sleep apnea under the current schedule — the schedule skips straight from 30% to 50%. That's why the CPAP question matters so much: a prescribed breathing device is the line between the 30% tier and the 50% tier.
The 50% criteria turn on whether your treatment requires a breathing assistance device. In practice, that means a documented medical need — usually a sleep study (polysomnography or an approved home sleep test) confirming the diagnosis, followed by a prescription for CPAP or a similar device. The key word is requires. A machine you picked up on your own, without a diagnosis and a documented medical need behind it, is not the same as a prescribed device tied to a confirmed condition. The record has to show the medical requirement, not just possession.
This is also why the sleep study is the load-bearing piece of evidence in a sleep apnea claim. Without an in-range diagnostic study on file, there's often nothing for a rater to anchor the 50% level to. If you're preparing a claim, that study — and the prescription that follows it — is the first thing to get into your records.
A large share of sleep apnea claims aren't filed as standalone conditions at all — they're filed as secondary to something already service-connected. Common theories include sleep apnea secondary to certain mental health conditions, to chronic sinus or nasal conditions like rhinitis, or to weight change connected to medication or another service-connected disability. We cover how secondary claims are built in our guide to first-claim mistakes, but the short version is that a secondary claim generally needs three things: a current diagnosis of the sleep apnea, an already service-connected primary condition, and a medical nexus opinion connecting the two.
The nexus is where most secondary sleep apnea claims are won or lost. A rater can't infer the medical link for you — it has to be stated by a qualified clinician who explains why, in your case, the primary condition caused or aggravated the sleep apnea. That's a medical judgment, not a paperwork trick, and it's the piece most veterans underbuild.
A 50% rating is meaningful on its own, but sleep apnea rarely lives alone on a rating decision. Because VA uses combined ratings math rather than simple addition, a 50% sleep apnea rating combines with your other conditions in a way that isn't intuitive — 50% plus 30% does not equal 80%. If you want to see how a new 50% would actually move your combined rating and your monthly compensation, run the numbers with our VA disability calculator before you assume anything. We also break down the combined-ratings method step by step in VA math explained.
You may have seen headlines that the VA is planning to overhaul how sleep apnea is rated. That's accurate, and it's worth understanding, but as of mid-2026 it is still a proposed rule — not the law raters are applying today. The proposal would shift the rating away from "what treatment is prescribed" and toward "how well that treatment works," with levels based on whether treatment is effective, ineffective, or unusable, and whether there's related end-organ damage. Under the drafts that have circulated, the automatic 50% for simply being prescribed a CPAP would go away, and the 30% daytime-sleepiness level would be restructured.
Two things to keep straight. First, none of that is final until a final rule is published, so current claims are still decided under the 0/30/50/100 schedule above. Second, VA has indicated that veterans who already hold a sleep apnea rating are generally protected — an existing rating can't simply be cut without following the due-process rules that require evidence of sustained improvement. Rules do change, though, so if this condition matters to your claim, confirm the current status on VA's official channels or with an accredited representative before you file.
Do I need a CPAP machine to get a 50% sleep apnea VA rating?
Under the current Diagnostic Code 6847, the 50% level applies when treatment requires a breathing assistance device such as a CPAP. The device has to be medically required based on a diagnosis — typically confirmed by a sleep study — not simply owned.
Can sleep apnea be service-connected as a secondary condition?
Yes. It's frequently claimed as secondary to another service-connected condition. A secondary claim generally needs a current diagnosis, an already service-connected primary condition, and a medical nexus opinion linking the two.
Will the proposed rule changes lower my current rating?
As of mid-2026 the changes aren't final. If a new rule is adopted, VA has said existing ratings are generally protected and can't be reduced without due-process rules that require evidence of sustained improvement. Only VA decides any rating or reduction.
