Sleep apnea VA ratings and the C&P exam
The rating does not turn on how badly you sleep, or on how severe the sleep study says your apnea is. It turns on what treatment the condition requires.
VA rates service-connected sleep apnea at 0%, 30%, 50%, or 100% under diagnostic code 6847 in 38 CFR § 4.97. Requiring a breathing assistance device such as a CPAP machine is the 50% criterion. The C&P exam documents the diagnosis, which must be confirmed by a sleep study, the treatment you require, your symptoms, and how the condition affects your work (VA Sleep Apnea DBQ). A CPAP prescription decides the rating once the condition is service connected; it does not establish service connection by itself.
The four tiers of DC 6847
| Rating | What the schedule requires (DC 6847, sleep apnea syndromes: obstructive, central, mixed) |
|---|---|
| 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. |
CPAP and the VA rating. The 50% criterion is that the condition requires use of a breathing assistance device, such as a CPAP machine. Severity labels do not set the rating. Whether your sleep study reads mild, moderate, or severe, there is no separate "mild", "moderate", or "severe" sleep apnea rating. The treatment criteria in the table decide it, so a "moderate sleep apnea" or "severe sleep apnea" rating comes out the same as any other if the treatment is the same.
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. The schedule is measuring the treatment, not the disease.
The 50% tier has a single criterion: the condition requires use of a breathing assistance device. There is no degree-of-severity scale to argue over. It is also the tier VA has proposed to change, on the stated ground that the current criteria rate the treatment prescribed rather than the impairment that remains.
The C&P exam
The sleep apnea exam form is short. The examiner reviews your records and history, confirms the diagnosis against a sleep study, records whether continuous medication or a breathing assistance device such as a CPAP is required, notes symptoms such as daytime sleepiness, and describes any effect on your ability to work. If a sleep study already in your record reflects your current condition, the form says repeat testing is not required, so do not assume you will need a new overnight study. Bring your sleep study report and the prescription or equipment paperwork for the machine. The form's device question, whether you require the use of a breathing assistance device such as a CPAP, is essentially the 50% criterion, so evidence that the machine is prescribed for your condition goes straight to it.
For the general approach to exams, including how to describe symptoms accurately without understating them, read Preparing for a C&P exam.
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's sleep apnea exam form states that the diagnosis must be confirmed by a sleep study. The form does not say what kind of study; in practice that usually means a polysomnography in a sleep lab or a home sleep apnea test, with a physician's interpretation and 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 before you separate, so the result lands in your service treatment records.
Service connection is the hard part
A diagnosis that comes years after separation does not end the claim: under 38 CFR § 3.303(d), a disease first diagnosed after discharge can still be service connected when the evidence shows it was incurred in service. There are 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: under 38 CFR § 3.159(a)(2), lay evidence is competent when it describes what a layperson could observe, such as loud snoring or pauses in breathing.
- Secondary to another service-connected condition. Under 38 CFR § 3.310, a disability caused by a service-connected condition is service connected too, and so is any worsening that would not have happened but for a service-connected condition, measured against a baseline level of severity shown in the evidence. The regulation still mentions natural progress, but since Spicer v. McDonough (Fed. Cir. 2023) VA's adjudication manual says it no longer considers natural progress in these claims. Sleep apnea can be 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 made chronic rhinitis and chronic sinusitis presumptive for veterans with qualifying service in the Persian Gulf region, Afghanistan, and certain other listed countries (38 U.S.C. §§ 1119(c), 1120), which can then support a secondary theory for apnea, but that still needs the opinion.
A negative opinion on sleep apnea may attribute the condition 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. VA weighs competing medical opinions, and an opinion that deals with the risk factors gives the decision-maker a reason to prefer it over one that does not.
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 respiratory schedule has its own rule, and it goes further than the general anti-pyramiding rule in § 4.14. Under § 4.96(a), ratings under diagnostic codes 6600 through 6817 and 6822 through 6847 are not combined with each other, whether or not the symptoms overlap. That range covers asthma (DC 6602), COPD (DC 6604), and sleep apnea itself. The VA instead assigns a single rating under the code for the predominant disability, elevated to the next higher evaluation where the severity of the overall disability warrants it. Chronic sinusitis (DCs 6510 through 6514) and rhinitis (DCs 6522 through 6524) sit outside that range, so they can carry their own ratings alongside sleep apnea, subject to § 4.14.
A veteran is service connected for asthma, rated 30% under DC 6602 on a prescribed inhaled steroid controller, which the schedule treats as inhalational anti-inflammatory medication. A later sleep study records an apnea-hypopnea index of 9 events per hour, a physician prescribes a CPAP, and the sleep apnea is service connected as well.
- On its own, the sleep apnea meets the DC 6847 criterion for 50%: it requires use of a breathing assistance device. The AHI of 9 plays no part in that step.
- If the two were rated separately, § 4.25 would combine them, largest first: 50% leaves 50% efficiency, 30% of that remaining 50 is 15, and 50 plus 15 is 65%, which rounds to 70%.
- They are not rated separately. DC 6602 and DC 6847 both fall inside the range § 4.96(a) bars from combining, so the VA assigns one rating under the code for the predominant disability, which on these facts would most likely be the sleep apnea under DC 6847 at 50%. Elevation to 100%, the next higher DC 6847 evaluation, applies only if the overall disability is severe enough to warrant it.
On these facts, the likely result is a single 50% respiratory rating under DC 6847 in place of the 30% asthma rating, not a combined 70%: the sleep apnea grant lifts the respiratory rating by 20 points rather than adding a separate 50%. That changes the arithmetic for anyone already rated for asthma or COPD: a sleep apnea claim may replace the existing respiratory rating, or be absorbed by it, rather than add to it.
The proposed change
In February 2022 VA proposed rewriting DC 6847 so the rating would depend on whether treatment controls the symptoms, rather than on whether a device is required, and changing § 4.96(a) so sleep apnea could combine with other respiratory ratings (87 FR 8474). As of October 2026 it has not been finalized: a Federal Register search that month found only that proposal and a September 2024 supplemental proposal, and § 4.97 on eCFR still carries the four tiers above. A proposal changes no rating until VA finalizes it, and this guide does not predict when or whether that will happen. If the schedule does change, a readjustment is not by itself grounds to reduce a rating already in effect unless the condition has actually improved (38 CFR § 3.951(a)).
The checklist
- A sleep study with a physician's interpretation and an AHI.
- A prescription for a breathing assistance device such as a CPAP machine, plus the equipment paperwork.
- 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.
Sleep apnea rating questions
What happens at a C&P exam for sleep apnea?
The examiner reviews your records and history, confirms the diagnosis against a sleep study, records whether you need continuous medication or a breathing assistance device such as a CPAP, notes symptoms such as daytime sleepiness, and describes any effect on your work. VA's exam form says a new sleep study is not required if one already in your record reflects your current condition. Not everyone gets the same exam, and VA may decide a claim from your records without one if they already hold enough medical evidence (VA Sleep Apnea DBQ; VA.gov, VA claim exam).
What is the VA rating for sleep apnea?
Sleep apnea is rated under diagnostic code 6847 at one of four levels: 0% when it causes no symptoms but sleep disorder breathing is documented, 30% for persistent daytime hypersomnolence, 50% when it requires use of a breathing assistance device such as a CPAP machine, and 100% for the most serious complications. The full rating chart is above. A rating applies only once VA has service connected the condition, which is a separate question (38 CFR § 4.97).
Does a CPAP machine qualify for a 50% VA rating?
The 50% criterion is that the sleep apnea requires use of a breathing assistance device such as a CPAP machine. The schedule sets no number of hours of use; the question is whether the device is required for your condition, which the exam form asks in the same words. Having a machine does not prove service connection, which still needs a link to service or to a service-connected condition (38 CFR § 4.97).
What is the highest VA rating for sleep apnea?
100%. It applies to chronic respiratory failure with carbon dioxide retention or cor pulmonale, or to sleep apnea that requires a tracheostomy (38 CFR § 4.97).
What should a sleep apnea lay statement include?
Only what the writer personally saw or heard, with dates and how often. For example, a former roommate might write that from about March 2012, sharing a barracks room at a named base, they heard loud snoring most nights and several times a week saw the veteran stop breathing for a few seconds and wake up gasping. That example is made up to show the shape. The statement should not diagnose sleep apnea or say what caused it: a layperson is competent to describe what can be observed, such as snoring or pauses in breathing (38 CFR § 3.159(a)(2)). See how to write a lay statement.
How much does a 50% sleep apnea VA rating pay?
VA pays by your combined rating, not per condition. If 50% is your total combined rating and you have no dependents, the monthly payment is $1,132.90 under the rates effective December 1, 2025. Other ratings combine with it, and at 30% and above dependents add to the payment, so your amount may differ (VA.gov, veterans disability compensation rates). See adding dependents to your rating.
