How the VA rates sleep apnea
Sleep apnea is one of the most commonly claimed conditions in the system and one of the most misunderstood. The rating does not turn on how badly you sleep. It turns on one question: has a doctor put you on a machine?
Obstructive sleep apnea is rated under diagnostic code 6847 in 38 CFR § 4.97, the respiratory section of the rating schedule. It is a short entry with four tiers, and the gap between the tiers is enormous, which is why it attracts so much attention and so much bad advice.
The four tiers
| Rating | What the schedule requires |
|---|---|
| 0% | Asymptomatic, but with documented sleep disorder breathing. Service connected, but no compensation. |
| 30% | Persistent daytime hypersomnolence. In plain terms: you are sleepy during the day, every day, and a doctor has written it down. |
| 50% | Requires use of a breathing assistance device such as a continuous airway pressure (CPAP) machine. |
| 100% | Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires a tracheostomy. |
Notice what is not on that list. There is no tier for "severe" apnea, no tier tied to your apnea-hypopnea index, and nothing that asks how many times an hour you stop breathing. A veteran with mild apnea on a CPAP is rated higher than a veteran with severe apnea who refuses treatment. The schedule is measuring the treatment, not the disease.
The 50% tier has a single criterion: a doctor has prescribed a breathing device, and you use it. No degree-of-severity argument, no judgment call by the rater. That makes it one of the most objectively provable ratings in the whole schedule, which is exactly why the VA has been trying to change it.
The proposed change, and what it means for you
In 2022 the VA published a proposed rule that would rewrite DC 6847 so the rating depends on whether treatment actually controls your symptoms, rather than on whether a device was prescribed. Under the proposal, a veteran whose CPAP fully resolves the problem would be rated far lower than 50%.
As of this writing the proposal has not been finalized. Check the current text of § 4.97 at eCFR before you rely on any number in this guide, and remember two things about rule changes in general. First, ratings in place before a schedule change are generally protected from reduction solely because the criteria changed. Second, a claim is decided under whichever version of the schedule is more favorable for the period before a change takes effect. If you have a diagnosis and a prescription today, there is no advantage in waiting.
What a sleep apnea claim has to prove
Like every claim, it needs the three elements of service connection: a current diagnosis, something in service, and a medical link between them. Sleep apnea is unusual in how those three play out.
The diagnosis has to be a sleep study
A doctor writing "probable OSA" in a progress note is not a diagnosis for rating purposes. The VA wants a polysomnography, either in a sleep lab or a home sleep test, interpreted by a physician, with the apnea-hypopnea index recorded. If you do not have one yet, this is the first thing to get, and if you are still serving, get it while the care is free and the result lands in your service treatment records.
Service connection is the hard part
Most veterans were never diagnosed while serving. They were diagnosed years later, often because a spouse complained about the snoring. That leaves three routes to a service link:
- Direct, with in-service evidence. Sleep studies or diagnoses in your STRs, or documented symptoms: snoring noted at a physical, complaints of daytime fatigue, a roommate's statement that you stopped breathing in your sleep. Lay statements from people who bunked with you are real evidence here, and they are routinely ignored by veterans who do not realize it.
- Secondary to another service-connected condition. This is the most common successful route. Sleep apnea is frequently claimed as secondary to PTSD, depression, or anxiety, to chronic sinusitis or rhinitis, to conditions that caused weight gain, or to medications prescribed for a service-connected condition. Each of those requires a medical opinion explaining the mechanism in your case, not just citing a study. Read the secondary conditions guide for how that works.
- Presumptive. Sleep apnea is not a presumptive condition. If someone tells you the PACT Act covers it, they are wrong. The PACT Act added rhinitis and sinusitis, which can then support a secondary theory for apnea, but that still needs the opinion.
The most common denial language on sleep apnea is that the condition is attributable to age and weight rather than service. A good nexus letter addresses this head-on: it acknowledges the risk factors and explains why, in your case, the service-connected condition is at least as likely as not a cause or an aggravating factor anyway. An opinion that ignores the obesity argument gets overruled by an examiner who does not.
The C&P exam
The sleep apnea DBQ is short. The examiner confirms the diagnosis, confirms the sleep study, records whether a CPAP or other device is required, and notes any daytime symptoms. Bring your sleep study report and your prescription or the durable medical equipment paperwork for the machine. If your CPAP has a compliance download, bring that too. A prescribed machine that sits in a closet invites an examiner to write that the device is not "required," which is the one word the 50% tier turns on.
For the general approach to exams, including how to describe symptoms accurately without understating them, read Preparing for a C&P exam.
Sleep apnea and combined ratings
Because 50% is a large single rating, sleep apnea moves the combined total more than most conditions. A veteran at 70% for PTSD who adds a 50% sleep apnea rating lands at 85%, which rounds to 90%. Working the math yourself before you file tells you what the claim is actually worth; the combined rating guide walks through it, and the rating calculator does it for you.
One caution. The VA will not rate sleep apnea and another respiratory condition separately if they share the same symptoms, under the anti-pyramiding rule in § 4.14. Asthma and sleep apnea usually coexist fine, because the criteria measure different things, but if a denial cites pyramiding, that is the argument to answer.
The checklist
- A sleep study with a physician's interpretation and an AHI.
- A prescription for a CPAP, BiPAP, or oral appliance, plus the equipment paperwork.
- Evidence of use: compliance data, refill records for masks and filters.
- A service link: in-service symptoms with buddy statements, or a nexus opinion tying it to a service-connected condition.
- Your own statement on daytime symptoms, and if you file on a secondary theory, the name of the primary condition stated clearly on the 21-526EZ.
