The VA rates sleep apnea under Diagnostic Code 6847, and the rating schedule has four levels. Understanding what the VA looks for at each level before you file, or before you appeal, changes how you build your case. This article walks through each rating tier and what the evidence must show.
Sleep apnea ratings under DC 6847 run at 0%, 30%, 50%, and 100%. Each has specific clinical criteria tied to documented symptoms and treatment requirements.
A 0% rating is assigned when sleep apnea is asymptomatic or controlled by a non-breathing-assistance appliance. This sounds like a consolation prize, but it isn't meaningless: a 0% service-connected rating preserves your eligibility for secondary conditions and keeps the claim in your file. It's far better than not being service-connected at all.
If you're rated 0% and your symptoms are not actually controlled, gather documentation and file for an increase. The 0% rating often gets assigned when the examiner lacks enough symptom evidence.
A 30% rating requires persistent daytime hypersomnolence that doesn't respond adequately to treatment. This means documented excessive daytime sleepiness that interferes with functioning, even with treatment in place.
Veterans rated at 30% often have unrefreshing sleep, cognitive fog, or work performance issues despite using their CPAP. Document those symptoms specifically in your personal statement and in your medical visits.
This is the most commonly pursued sleep apnea rating, and it's driven by a single clear criterion: treatment with a continuous positive airway pressure (CPAP) device, or similar breathing assistance device, is required.
"Required" in this context means your physician has prescribed it. It doesn't mean you use it perfectly. It doesn't mean you love it. It means a licensed clinician reviewed your sleep study and determined that positive airway pressure therapy is medically necessary.
A polysomnography showing moderate-to-severe OSA (AHI generally above 15) combined with a CPAP prescription is the core evidence package for this rating. See sleep study results and your VA claim for details on how to read and use your sleep study report.
A 100% rating requires either chronic respiratory failure with carbon dioxide retention, cor pulmonale, or a surgically implanted breathing assistance device (including tracheostomy). This level reflects the most severe end of sleep-disordered breathing, where the condition has progressed to organ-level complications.
Most veterans with obstructive sleep apnea will not meet this threshold. The 100% pathway requires objective diagnostic confirmation: cor pulmonale is typically documented by elevated right heart pressures on echocardiogram or right heart catheterization; CO2 retention is confirmed by an arterial blood gas (ABG) showing pCO2 above 45 mmHg. If your pulmonologist has documented either finding, that record is the foundation for a 100% claim. Without those specific test results, the rating is not supportable regardless of symptom severity.
For most veterans, the realistic goal is the 50% rating. The path is:
If your claim is for service connection of sleep apnea at the 50% level, you need both the diagnosis and the treatment requirement documented. The VA will sometimes accept a CPAP prescription from a private physician; it does not have to come from the VA system.
The VA rates sleep apnea based on what treatment is required, not on how well you comply with it. An examiner or rater who penalizes your claim because your CPAP data shows inconsistent use is misapplying the rating criteria. The question is whether CPAP is medically required, not whether you've achieved perfect adherence.
If you're struggling with CPAP use, that's a clinical issue your provider can help address. For rating purposes, the prescription and the diagnosis are what matter.

Sleep apnea at the 50% level can combine with other ratings to push your combined rating above the 70% threshold needed for TDIU (Total Disability Individual Unemployability), provided you also meet the work history and functional impairment requirements. A veteran with 50% for sleep apnea and other service-connected conditions may qualify for TDIU even without a 100% scheduler rating.

The DC 6847 rating schedule is mechanical in the best possible way. The criteria are clear. If you can document them, you can support the right rating. Before filing:
