Sleep apnea is the most commonly claimed VA disability condition — and the 50% rating is the one veterans want most. But that 50% rating hinges on one critical requirement: use of a "breathing assistance device." If you have a sleep apnea diagnosis but no CPAP machine, or if you refused CPAP therapy, you may be wondering whether you can still get the 50% rating. The answer is more nuanced than most veterans realize, and this guide explains exactly what counts as equivalent treatment, how to get properly prescribed, and how secondary conditions can add to your overall rating regardless of your CPAP status.
Sleep apnea is rated under Diagnostic Code 6847 in 38 CFR Part 4, §4.97. The rating criteria are:
| Rating | Criteria |
|---|---|
| 100% | Chronic respiratory failure with carbon dioxide retention, cor pulmonale, or requires tracheostomy |
| 50% | Requires use of breathing assistance device such as CPAP machine |
| 30% | Persistent daytime hypersomnolence (excessive sleepiness) |
| 0% | Asymptomatic but with documented sleep disorder breathing |
The 50% tier is the most commonly sought. It does not say "CPAP" specifically — it says "breathing assistance device." This distinction matters significantly, as we'll explore below.
The language in DC 6847 — "requires use of a breathing assistance device such as continuous positive airway pressure (CPAP) machine" — creates two important elements:
The key is that a licensed physician must have prescribed or recommended the device. Self-purchased devices without a prescription, or devices a veteran uses on their own without a sleep study and diagnosis, do not satisfy this requirement.
The VA has consistently held that devices that serve the same function as CPAP — delivering pressurized air to keep the airway open — qualify as "breathing assistance devices" for the 50% rating. These include:
BiPAP delivers two different pressure levels: a higher pressure on inhalation and a lower pressure on exhalation. It is prescribed for veterans who cannot tolerate CPAP pressure, or who have more complex breathing needs (such as central sleep apnea or hypoventilation syndrome). A BiPAP prescription clearly satisfies the 50% requirement.
APAP automatically adjusts pressure throughout the night in response to detected apnea events. It is functionally equivalent to CPAP and is routinely prescribed as an alternative. An APAP prescription satisfies the 50% rating requirement.
ASV is used for complex sleep apnea and central sleep apnea. It adjusts pressure and backup breathing rate in real time. A prescription for ASV satisfies the breathing device requirement.
Some veterans with severe sleep apnea use supplemental oxygen in conjunction with CPAP. Both devices count.
Any prescribed positive airway pressure device (CPAP, BiPAP, APAP, ASV) satisfies the 50% rating requirement. What matters is that a physician determined you require the device and prescribed it — not the specific device type.
This is one of the most frequently asked questions in VA sleep apnea claims. Mandibular advancement devices (MADs) — oral appliances that reposition the jaw to open the airway — are increasingly prescribed as alternatives to CPAP for mild to moderate sleep apnea, or for veterans who are truly CPAP-intolerant.
The VA's position on dental appliances has been inconsistent in BVA decisions. However, the weight of BVA and CAVC case law supports that a prescribed oral appliance qualifies as a "breathing assistance device" under DC 6847 if:
However, this is an area where VA raters sometimes deny the 50% rating, requiring veterans to appeal. If you have a prescribed dental appliance for sleep apnea and were denied 50%, consider filing a Supplemental Claim with additional evidence from your prescribing physician explicitly stating the appliance is a breathing assistance device required for your OSA treatment.
If you have a sleep apnea diagnosis but no prescribed breathing device, you are limited to a maximum of 30% for persistent daytime hypersomnolence — if that symptom is present. A 30% rating is still significant (worth approximately $524/month for a single veteran with no dependents in 2026), but it's substantially less than the 50% tier.
Here's the important thing to understand: the absence of a CPAP prescription is often a paperwork problem, not a medical one. Most veterans with moderate or severe obstructive sleep apnea on their sleep study results qualify for a CPAP prescription — they just haven't pursued one. See the section below on how to get prescribed.
Some veterans have been prescribed CPAP but refuse to use it, for various reasons (claustrophobia, discomfort, inconvenience). The VA's position is that if a device is prescribed but the veteran refuses to use it, this does not automatically prevent the 50% rating — because the rating language is "requires use," and a prescription constitutes the physician's determination that the device is required. However, raters sometimes deny 50% for non-compliance, and these cases are frequently litigated. If you were prescribed CPAP and denied 50% due to non-use, speak with a VA-accredited attorney.
If you have a sleep apnea diagnosis but no CPAP prescription, here's the path to getting one — and qualifying for the 50% rating:
Many veterans with CPAP prescriptions are still rated at 30% or 0% because their claim wasn't properly filed. Use claim.vet to check if you're being fairly compensated.
Check My Sleep Apnea Rating →Even if your sleep apnea rating is "only" 30% due to the absence of a CPAP, the secondary conditions caused or aggravated by sleep apnea can significantly increase your overall combined rating. File these as secondary service-connected conditions:
Obstructive sleep apnea is a well-established cause of secondary hypertension. Repeated nighttime oxygen desaturation activates the sympathetic nervous system and raises blood pressure. If you have sleep-apnea-related hypertension, it may qualify as secondary to your service-connected sleep apnea. See our hypertension rating guide.
Sleep apnea is independently associated with atrial fibrillation, heart failure, and coronary artery disease through repeated hypoxia and autonomic nervous system dysregulation. If you have a cardiac condition and service-connected sleep apnea, explore a secondary claim.
The relationship between PTSD and sleep apnea is bidirectional — PTSD often causes or worsens sleep apnea, and sleep apnea worsens PTSD symptoms by fragmenting sleep. If your sleep apnea is secondary to PTSD, or if your PTSD is worsened by sleep deprivation from untreated sleep apnea, document this connection. See also our guide on VA sleep apnea ratings and the 2026 sleep apnea rating changes.
Chronic sleep deprivation from untreated sleep apnea causes and worsens depression. If you have a service-connected sleep apnea diagnosis and also suffer from depression, file a secondary claim for depression.
To claim VA compensation for sleep apnea, you must connect it to your service. Common service-connection pathways:
