How to Claim Sleep Apnea Secondary to PTSD: Complete Guide for Veterans

By VA Rating Assistant Team

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 to 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:

  1. Service-connection for PTSD (primary condition)
  2. Current sleep apnea diagnosis (sleep study / polysomnography)
  3. Medical nexus linking sleep apnea to PTSD (caused or aggravated)

How to file a sleep apnea secondary claim

  1. Confirm you’re service-connected for PTSD.
  2. Get a sleep study.
  3. Start CPAP treatment (if prescribed) and document usage.
  4. Get a nexus letter (or a strong medical opinion).
  5. 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
