If you're service-connected for PTSD and struggle with sleep problems, you may have sleep apnea caused by your PTSD — and you can claim it as a secondary condition for additional VA disability compensation.
What is sleep apnea?
Obstructive Sleep Apnea (OSA) is a condition where your breathing repeatedly stops and starts during sleep because your airway becomes blocked. Common symptoms include:
- Loud snoring
- Gasping or choking during sleep
- Daytime fatigue despite sleeping 7–8 hours
- Morning headaches
- Difficulty concentrating
The VA rates sleep apnea under 38 CFR § 4.97, Diagnostic Code 6847 at 0%, 30%, 50%, or 100% depending on severity and treatment requirements.
Why PTSD can cause or aggravate sleep apnea
Medical research supports a strong association between PTSD and sleep apnea. Common mechanisms include:
- Hyperarousal and fragmented sleep
- Nightmares and frequent awakenings
- Medication effects (sedating meds can worsen airway collapse)
- Weight gain and reduced activity associated with PTSD
How sleep apnea is rated by the VA
0% rating
- Asymptomatic, but with documented sleep disorder breathing
30% rating
- Persistent daytime hypersomnolence (excessive daytime sleepiness)
50% rating
- Requires the use of a breathing assistance device such as a CPAP
100% rating
- Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires tracheostomy
What evidence do you need for a secondary sleep apnea claim?
To win a sleep apnea secondary to PTSD claim, you need:
- Service-connection for PTSD (primary condition)
- Current sleep apnea diagnosis (sleep study / polysomnography)
- Medical nexus linking sleep apnea to PTSD (caused or aggravated)
How to file a sleep apnea secondary claim
- Confirm you’re service-connected for PTSD.
- Get a sleep study.
- Start CPAP treatment (if prescribed) and document usage.
- Get a nexus letter (or a strong medical opinion).
- File the claim as secondary to PTSD and attend the C&P exam.

Common mistakes that lead to denials
- Filing without a sleep study
- Submitting a weak nexus (no “at least as likely as not” language)
- Not using prescribed CPAP (or having poor compliance without explanation)
- Filing as direct service connection instead of secondary when PTSD is the real pathway
