Rating Criteria by Level
Under 38 CFR Part 4, DC 6847, the VA evaluates sleep apnea on a four-level scale. The levels are not based on severity of apnea events (AHI score); they are based on symptoms and treatment requirements.
Criteria: Sleep disorder breathing is documented (sleep study confirmed), but the veteran has no current symptoms: no daytime somnolence, no prescription for a breathing device.
A 0% rating is non-compensable, meaning no monthly payment. But it is still service-connected, which matters: it preserves your right to claim secondary conditions, and if your condition worsens you can seek an increase without reopening the original service-connection question.
Criteria: The veteran experiences persistent daytime hypersomnolence (excessive daytime sleepiness that affects functioning) but has not been prescribed a breathing assistance device.
Daytime hypersomnolence must be persistent and documented. A VA examiner will ask about sleep quality, fatigue, and how sleepiness affects daily activities and work. A sleep study showing moderate apnea without a current CPAP prescription typically falls in this range.
Criteria: The veteran requires the use of a breathing assistance device (most commonly a CPAP or BiPAP machine). The prescription and documented use of the device is the sole criterion for this level.
This is by far the most common sleep apnea rating. If a doctor has prescribed a CPAP and you use it, you meet the 50% standard regardless of apnea-hypopnea index (AHI) severity. Critically, you do not need to prove the device is working perfectly. CPAP compliance records help but the prescription itself is the trigger.
Most common rating: CPAP prescription qualifies
Criteria: Chronic respiratory failure with carbon dioxide retention or cor pulmonale (right-sided heart failure from lung disease), or the veteran requires a surgically placed tracheotomy.
The 100% schedular rating for sleep apnea requires objective evidence of CO2 retention on arterial blood gas testing or documented cor pulmonale. This level is uncommon. Many veterans who cannot work due to sleep apnea and other conditions pursue TDIU rather than the 100% schedular rate.
How to Service-Connect Sleep Apnea
Service connection requires three things: a current diagnosis, an in-service event or injury, and a medical nexus linking the two. Sleep apnea is commonly connected in three ways:
Direct Service Connection
Sleep apnea was diagnosed during service or within a year of separation, and is documented in your service treatment records. A sleep study ordered during active duty or CPAP prescribed before separation is strong evidence.
Secondary to PTSD or TBI
PTSD and TBI both disrupt the neurological regulation of sleep and breathing. A nexus letter from a physician stating that your PTSD or TBI caused or aggravated sleep apnea establishes secondary service connection.
Secondary to Weight Gain from Service
If service-connected conditions (medication side effects, limited mobility from a knee or back injury) caused weight gain that contributed to sleep apnea, a nexus opinion can establish secondary connection on that basis.
What Happens at Your C&P Exam
The VA will schedule a compensation and pension exam with a VA or contracted examiner. For sleep apnea, the examiner will typically:
- Review your sleep study results (AHI score, O2 desaturation levels)
- Ask whether you have a CPAP/BiPAP prescription and whether you use it
- Assess daytime symptoms (fatigue, hypersomnolence, cognitive fog)
- Document any secondary conditions you've raised (hypertension, PTSD relationship)
- Provide a nexus opinion if secondary connection is claimed
Bring your CPAP prescription, any compliance reports from your device, and your original sleep study. If you have a private nexus opinion, submit it before the exam.
Secondary Conditions to Sleep Apnea
Once sleep apnea is service-connected, you can file secondary claims for conditions it caused or worsened. Each adds its own rating to your combined total.
HypertensionSleep apnea is a documented cause of elevated blood pressure. Rated 10–60%.
Atrial FibrillationNocturnal oxygen desaturation is a recognized trigger for AFib. Rated 10–30%.
Depression / AnxietyChronic sleep deprivation from apnea worsens mood disorders. Rated 0–100% on the mental disorders scale. Often secondary to PTSD already on file.
Cognitive ImpairmentSustained hypoxia affects memory and processing. Can be rated separately or folded into a TBI claim.
GERDPressure changes from apnea events aggravate acid reflux. Rated 10–60%.

Sleep Apnea VA Rating FAQ
What is the VA rating for sleep apnea with a CPAP?
A veteran prescribed and using a CPAP or BiPAP machine is rated 50% under diagnostic code 6847. This pays $1,132.90/month (veteran alone, 2026 rates). The CPAP requirement is the single criterion; there is no separate severity test at the 50% level.
Can you get VA disability for sleep apnea without a CPAP?
Yes. Documented but asymptomatic sleep apnea is rated 0% (non-compensable but service-connected). Persistent daytime hypersomnolence without a CPAP prescription qualifies for 30% ($552.47/mo). You can also be service-connected without currently using a CPAP, if sleep apnea was diagnosed in service.
Is sleep apnea a presumptive VA condition?
Sleep apnea is not a listed presumptive condition, but it commonly qualifies as a secondary condition to PTSD, TBI, or military noise exposure. The nexus just needs to be established by a physician.
Can sleep apnea be rated at 100%?
Yes, but the criteria require chronic respiratory failure with CO2 retention, cor pulmonale, or a surgically placed tracheotomy. This is rare. Most veterans at high combined ratings pursue TDIU rather than a 100% schedular rating for sleep apnea alone.
Does sleep apnea qualify for TDIU?
Sleep apnea alone at 50% does not meet TDIU thresholds (60% single rating or 70% combined with one at 40%). But a 50% sleep apnea combined with other conditions can push a veteran over the threshold.
Can sleep apnea be rated secondary to PTSD?
Yes. PTSD causes hyperarousal and sleep disruption that can trigger or worsen obstructive sleep apnea. A medical nexus opinion linking the two is required. Many veterans with service-connected PTSD successfully add sleep apnea as a secondary condition.
Will the VA reduce my sleep apnea rating if I stop using my CPAP?
Potentially. VA ratings can be reduced if the condition shows sustained improvement. If you stop CPAP use and have a C&P exam showing no symptoms, the 50% rating could be reduced to 30% or 0%. Do not discontinue prescribed treatment before a C&P exam.
