Sleep apnea (VA Diagnostic Code 6847) is one of the five most commonly service-connected VA disabilities. It's also one of the most commonly rated wrong — specifically at 0% or 30% when veterans should be getting 50%.
The CPAP Rule That Most Veterans Don't Know
Under 38 CFR Part 4, DC 6847, the rating schedule is explicit:
| Rating | Criteria |
|---|---|
| 0% | Asymptomatic, documented sleep disorder breathing |
| 30% | Persistent daytime hypersomnolence |
| 50% | Requires use of breathing assistance device (CPAP/BiPAP) |
| 100% | Chronic respiratory failure with CO2 retention or cor pulmonale |
The 50% rule in plain English: If your doctor prescribed you a CPAP machine, you rate 50%. Not "if you use it every night" — the word in the CFR is "requires use." A CPAP prescription satisfies that criterion regardless of compliance data.
Veterans rated at 0% or 30% who are CPAP users have been incorrectly rated and should file a Supplemental Claim or Higher-Level Review.
Service Connection Pathways
Sleep apnea is not a presumptive condition for most veterans — it requires direct or secondary service connection.
Direct service connection: Sleep study ordered or CPAP prescribed while on active duty. Service treatment records documenting snoring complaints, extreme fatigue, or witnessed apnea episodes.
Secondary service connection (most common path):
- PTSD → Sleep Apnea: PTSD disrupts sleep architecture and is extensively documented in medical literature as causally linked to obstructive sleep apnea. A nexus letter from a psychiatrist or sleep physician connecting PTSD-related sleep disruption to OSA is strong, contestable evidence.
- TBI → Sleep Apnea: TBI affects neurological regulation of breathing during sleep. Central and mixed sleep apnea in TBI veterans is well-supported in peer-reviewed literature.
- Weight gain secondary to a service-connected condition: If a service-connected injury, medication, or disability caused significant weight gain contributing to OSA, a secondary claim under 38 CFR §3.310 is viable.
VA's standard denial language — "sleep apnea is a common condition not unique to veterans" — is routinely used to deny claims that have valid secondary nexus. That denial is contestable with an Independent Medical Opinion (IMO) from a qualified sleep physician.
What to Bring to Your C&P Exam
Your Compensation & Pension exam for sleep apnea needs:
- Your polysomnography (PSG) report with AHI documented
- Your CPAP prescription or equipment documentation
- CPAP compliance data (SD card printout or app export) — not required for the 50% rating, but brings it
- Treatment records from your sleep physician documenting CPAP medical necessity
- Buddy statements on VA Form 21-10210 if you need to establish in-service onset
Note: AHI severity (mild/moderate/severe) does not determine your rating percentage. A veteran with mild sleep apnea (AHI 8) prescribed a CPAP is still rated 50% under DC 6847.
Secondary Claims From Sleep Apnea
If you're already service-connected for sleep apnea, you may have secondary claims for:
- Hypertension (DC 7101): Untreated OSA is causally linked to elevated blood pressure
- Depression/anxiety: Sleep deprivation and oxygen desaturation events directly impact mood regulation
- Cognitive impairment: Chronic oxygen deprivation during sleep affects memory and executive function
