What Is Sleep Apnea
Sleep apnea is a breathing disorder where your airway collapses during sleep, causing repeated pauses in breathing that can last from a few seconds to over a minute. The VA rates sleep apnea at 0%, 30%, 50%, or 100% based on the severity of the condition and whether you use continuous positive airway pressure (CPAP) therapy or other treatment.
VA Rating Schedule for Sleep Apnea
The VA uses diagnostic criteria and treatment response to assign ratings under 38 CFR 4.97, Schedule for the Respiratory System:
- 0% (Noncompensable): Sleep apnea documented by sleep study but no daytime hypersomnolence or no CPAP use required
- 30% (Mild): Daytime hypersomnolence and uses CPAP or similar device; mild sleep disturbance with some breathing pauses
- 50% (Moderate): Persistent daytime hypersomnolence despite CPAP use; moderate frequency of apneic episodes
- 100% (Severe): Severe symptoms including cor pulmonale (right heart failure from pulmonary hypertension), right ventricular hypertrophy, or severe pulmonary hypertension
C&P Exam and Sleep Apnea
During your Compensation and Pension (C&P) exam, the VA examiner will review your sleep study results and ask about daytime symptoms like excessive fatigue, morning headaches, and difficulty concentrating. You'll need documented evidence from a sleep study showing an Apnea-Hypopnea Index (AHI) score. The examiner also assesses whether you're using CPAP therapy consistently, as treatment compliance directly affects your rating. If you haven't had a sleep study, request one through your VA provider, as a diagnosis without objective testing is harder to rate at higher levels.
Service Connection and Nexus Letters
If sleep apnea isn't already service-connected, you'll need to establish nexus, meaning a medical link between your military service and the condition. Sleep apnea is commonly related to service-connected conditions like PTSD, traumatic brain injury, or neck injuries that affect airway mechanics. A nexus letter from your VA or private physician stating that sleep apnea is "at least as likely as not" caused by or aggravated by your service is critical. Veterans with multiple service-connected conditions should ask their doctor whether sleep apnea qualifies as a secondary condition.
Sleep Apnea as a Secondary Condition
Sleep apnea often develops as a secondary condition from other service-connected disabilities. For example, obesity rated at service connection may cause or worsen sleep apnea. PTSD and sleep apnea frequently occur together. If you already have a rated condition and later develop sleep apnea linked to it, file a claim for sleep apnea as a secondary condition. Include medical evidence showing the relationship between your existing condition and the new diagnosis.
Appeals and Rating Increases
If the VA rates your sleep apnea lower than your condition warrants, you can appeal within one year of the rating decision. Submit new sleep study results, treatment records showing CPAP use, and statements from your doctor about worsening daytime symptoms. A Veterans Service Officer (VSO) can help you file a higher-level review or supplemental claim at no cost. The VA must explain in writing why your condition doesn't meet the criteria for a higher rating.
Common Questions
- Do I need CPAP to get rated? No. You can be rated at 30% or higher even without CPAP if you have documented daytime hypersomnolence and sleep study results showing apneic episodes. However, untreated sleep apnea that doesn't cause daytime symptoms typically rates at 0%.
- What if my sleep study was done before service? If you have evidence showing your sleep apnea worsened during or after military service, you can still establish service connection. This requires a nexus letter explaining the aggravation.
- Can I appeal a 0% rating? Yes. If you develop daytime symptoms after the initial exam or obtain new sleep study data, file a supplemental claim with updated medical evidence. The VA must re-evaluate based on current condition.
