If you snore loudly, wake up gasping, or feel exhausted no matter how long you sleep, you may be living with obstructive sleep apnea (OSA). If you already have a service-connected condition, you may be able to get VA compensation for your sleep apnea, even if it was never diagnosed in service.

This is called secondary service connection. Here's how it works, what evidence matters, and what to do if VA says no.

What Is Secondary Service Connection?

Under VA regulation 38 CFR § 3.310, a disability that is "proximately due to or the result of" a service-connected condition is also service connected.

The rule also covers aggravation. If a service-connected condition didn't cause your sleep apnea but made it worse, VA can compensate you for the added severity beyond your baseline. Aggravation claims depend on medical records showing how severe the condition was before it worsened.

The Three Things You Need to Prove

  1. A current diagnosis. VA wants OSA confirmed by a sleep study.
  2. A service-connected primary condition. This is a condition you're already rated for, or are claiming at the same time.
  3. A medical link (nexus). A medical opinion must say it is "at least as likely as not" (a 50% or greater chance) that your service-connected condition caused or aggravated your sleep apnea, and explain why.

That third piece is where most claims are won or lost.

Conditions Veterans Commonly Link to Sleep Apnea

No condition automatically leads to service connection for sleep apnea. Every case turns on its own medical facts. Veterans often pursue secondary claims based on:

  • PTSD and other mental health conditions. VA does not presume a link between PTSD and sleep apnea, so a well-reasoned medical opinion is essential.
  • Weight gain caused by service-connected conditions or medications. Obesity itself isn't a compensable disability. But a VA General Counsel precedent opinion (VAOPGCPREC 1-2017) recognized that obesity can be an "intermediate step." For example, a knee injury limits your activity, or a psychiatric medication causes weight gain, and that weight gain leads to sleep apnea. In Walsh v. Wilkie (2020), the U.S. Court of Appeals for Veterans Claims held that this theory also applies when a service-connected condition aggravates obesity. In Garner v. Tran (2021), the same court addressed when the record raises this theory.
  • Chronic rhinitis or sinusitis. Ongoing nasal and sinus problems are sometimes argued to contribute to airway blockage during sleep.
  • Medications for service-connected conditions. Some veterans argue that opioids or sedatives prescribed for service-connected pain or mental health conditions affect their breathing during sleep.

Your doctor, not a website, should be the one connecting the dots in your case.

Don't Forget Direct Service Connection

If you had symptoms in service, like snoring or gasping that a bunkmate noticed, or constant fatigue, you may be able to claim sleep apnea directly. You can argue both theories in the same claim.

How VA Rates Sleep Apnea Right Now

VA rates sleep apnea under Diagnostic Code 6847 (38 CFR § 4.97). As of November 2026, the criteria are:

  • 0%: No symptoms, but documented sleep-disordered breathing
  • 30%: Persistent daytime sleepiness
  • 50%: Requires a breathing assistance device, such as a CPAP machine
  • 100%: Chronic respiratory failure with carbon dioxide retention or cor pulmonale, or requires a tracheostomy

In 2022, VA proposed rating sleep apnea based on how well treatment works, which could mean a lower rating for a veteran whose CPAP controls symptoms. That proposal is not final. VA's latest regulatory agenda projects a final rule in April 2027, but that target has slipped before. Until a final rule takes effect, the current criteria apply.

Evidence That Strengthens Your Claim

  • A sleep study confirming your diagnosis.
  • A private nexus opinion from a doctor who reviews your records and explains the medical reasoning.
  • Buddy and spouse statements from people who've heard you stop breathing at night or seen you nod off during the day.
  • Your own statement describing when symptoms started and how they affect your life.
  • Your C&P exam. Be honest and thorough, and get a copy of the report afterward.

Why Sleep Apnea Claims Get Denied

Common reasons include no sleep study, a negative or poorly explained C&P opinion, an examiner who never considered aggravation, or one who ignored a weight-gain theory the record supported. Many of these problems can be fixed.

Your Appeal Options

If VA denies your claim, you generally have three choices:

  • Supplemental Claim: Submit new and relevant evidence, such as a new nexus opinion.
  • Higher-Level Review: A senior reviewer checks the same evidence for errors. Request it within one year of your decision.
  • Board Appeal: A Veterans Law Judge reviews your case, with options to add evidence or request a hearing. This also must be filed within one year.

Choosing the right option, at the right time, can make a real difference.
