Sleep apnea can be service connected secondary to tinnitus only if medical evidence shows your service-connected tinnitus caused it or made it worse, and current research does not establish that tinnitus causes obstructive sleep apnea. That makes this one of the harder secondary claims to support, so the quality of the medical evidence matters a great deal. If you’re a veteran with both conditions, understanding what the Department of Veterans Affairs (VA) looks for can help you decide whether to pursue the claim and what evidence to gather.
Key takeaways
- Tinnitus and sleep apnea often occur together, but studies that find a link mostly suggest sleep apnea may raise the risk of tinnitus, and none has shown that tinnitus causes obstructive sleep apnea.
- A secondary claim needs medical evidence that tinnitus caused or worsened sleep apnea at a level of “at least as likely as not,” and the VA rater weighs that evidence and decides.
- Gather your sleep study, treatment records, and tinnitus history, and consider talking with a VA-accredited representative before filing.
What does “secondary to tinnitus” mean?
A condition is secondary when it was caused or worsened by a disability that VA has already service connected. Under 38 CFR 3.310, a disability that is “proximately due to or the result of” a service-connected condition can itself be service connected.
There are two ways a secondary claim can work:
- Causation: The service-connected condition directly caused the new condition.
- Aggravation: The service-connected condition made a non-service-connected condition worse than its natural progress. VA needs medical evidence that establishes the condition’s baseline severity before the worsening, then rates only the added disability.
For this claim, tinnitus (ringing, buzzing, or other sounds in the ears or head) would be the service-connected condition, and sleep apnea would be the secondary one. The next question is whether medicine supports that link.
Can tinnitus cause sleep apnea?
Current evidence doesn’t show that tinnitus causes obstructive sleep apnea (OSA), the most common type. According to the National Heart, Lung, and Blood Institute, OSA is caused by conditions that block airflow through the upper airway during sleep.
The main risk factors the institute lists are physical:
- Airway anatomy, such as enlarged tonsils or a large neck or tongue.
- Excess weight, especially fat around the neck.
- Age and sex, since risk rises with age and OSA is more common in men.
- Family history, alcohol use, and smoking.
- Certain medical conditions, including thyroid problems and heart or kidney failure.
Tinnitus isn’t on that list. Because tinnitus affects how you hear sound rather than how air moves through your throat, a direct causal link is hard to explain medically. That doesn’t rule out every claim, but it means any opinion supporting the link needs clear reasoning tied to your records.
What does the research say about tinnitus and sleep apnea?
Research shows the two conditions are associated, but the evidence mostly points in the opposite direction from this claim. In a national survey analysis of 4,871 U.S. adults, people with OSA had higher odds of bothersome tinnitus after adjusting for other factors, and the authors concluded that OSA may be a risk factor for tinnitus. An earlier case-control study of 130,788 middle-aged and older adults in Taiwan found that people diagnosed with sleep apnea had higher odds of a later tinnitus diagnosis.
Both studies show association rather than cause and effect, and neither looked at whether tinnitus leads to sleep apnea. Still, a medical opinion for a secondary claim has to explain how tinnitus led to sleep apnea, and the published research doesn’t currently supply that explanation.
Tinnitus does affect sleep in other ways. The National Institute on Deafness and Other Communication Disorders notes that tinnitus can affect some people’s ability to sleep or concentrate, and that in severe cases it can lead to anxiety or depression. Trouble falling or staying asleep (insomnia) is a different condition from sleep apnea, which involves breathing that stops and restarts during sleep. A separate claim for a sleep or mental health condition may fit some veterans’ situations better, so it helps to know exactly which diagnosis you have.
How could tinnitus be connected to sleep apnea in a claim?
Any connection has to come from your individual medical record and a physician’s reasoning. A physician reviewing your case would generally look at:
- Your diagnosis: Whether a sleep study confirmed sleep apnea, and which type.
- The timeline: When tinnitus began, when sleep symptoms started, and how each changed over time.
- Aggravation evidence: Whether records show your sleep apnea was measurably worse after tinnitus than at an earlier baseline.
- Other explanations: Weight, anatomy, age, medications, and other conditions that commonly cause or worsen sleep apnea.
After that review, the physician may conclude the evidence supports a link, or may conclude that it doesn’t. An honest opinion depends on the records, and a physician can’t promise a particular conclusion in advance. The HealthSource guide to VA secondary conditions explains how secondary links work more broadly.
If you’d like a physician to review your records and give an independent medical opinion (IMO), the veteran nexus services page explains how that review works. You must be physically located in a state where the physician is licensed at the time of the visit.
What evidence does VA need for a secondary claim?
VA generally needs proof of a current diagnosis, a service-connected condition, and medical evidence linking the two. VA’s evidence guidance says it usually needs medical records or medical opinions from health care providers to support that link, and in some cases accepts lay statements.
A medical opinion that supports a link (a nexus opinion) generally states whether the condition is “at least as likely as not,” meaning a 50% or greater probability, caused or worsened by the service-connected disability. Under VA’s benefit-of-the-doubt rule, when positive and negative evidence are roughly balanced, the doubt is resolved in the veteran’s favor. That rule doesn’t apply when the evidence clearly weighs against the claim.
VA also has a duty to assist. Under 38 CFR 3.159, VA must provide an exam or obtain a medical opinion when the record shows a current disability and indicates it may be associated with a service-connected condition, but lacks enough medical evidence to decide. That exam is usually a compensation and pension (C&P) exam, and the HealthSource guide to C&P exams explains what to expect.
How does VA rate sleep apnea and tinnitus?
VA currently rates sleep apnea under diagnostic code 6847 and recurrent tinnitus under diagnostic code 6260.
Under the current respiratory rating schedule, sleep apnea ratings are:
- 0%: No symptoms, but a documented sleep breathing disorder.
- 30%: Persistent daytime sleepiness.
- 50%: Requires a breathing assistance device, such as a continuous positive airway pressure (CPAP) machine.
- 100%: Chronic respiratory failure with carbon dioxide retention or cor pulmonale (heart strain caused by lung disease), or a tracheostomy.
Under the current ear rating schedule, recurrent tinnitus receives a single 10% rating, whether it’s heard in one ear, both ears, or the head.
These criteria may change. VA published a proposed rule in 2022 that would rate sleep apnea based on how well treatment works and fold tinnitus into the rating for its underlying condition. As of October 2026, no final rule had been published, so check current rules before filing.
Where to get help with your claim
HealthSource physicians provide independent medical opinions but don’t prepare, file, or represent VA claims. Only VA-accredited attorneys, claims agents, and Veterans Service Organization (VSO) representatives can help you with the claim itself. You can find one through VA’s accreditation search.
When to seek medical attention
Sleep apnea is a medical condition first. Untreated sleep apnea may raise the risk of stroke, heart attack, and other serious problems, so talk with a health care provider if you snore loudly, wake up gasping, or feel very sleepy during the day. Contact a provider, too, if your tinnitus suddenly changes, affects only one ear, or comes with hearing loss or dizziness.
This is not an emergency service. If you have chest pain, trouble breathing, signs of a stroke, or another emergency, call 911 or go to the nearest emergency room. If you’re having thoughts of suicide or are in crisis, call or text 988 to reach the Suicide & Crisis Lifeline. Veterans can press 1.
Frequently asked questions
Is sleep apnea secondary to tinnitus a strong claim?
It’s generally a difficult claim, because research hasn’t shown that tinnitus causes obstructive sleep apnea. Some veterans may have a stronger basis through a different secondary condition or a direct service connection. An accredited representative can help you compare options.
Will a nexus letter make VA approve the claim?
No. A medical opinion is one piece of evidence, and the VA rater weighs all the evidence and decides. A physician may also conclude after reviewing your records that the evidence doesn’t support a link.
Does tinnitus cause insomnia?
Tinnitus can make it harder for some people to fall asleep or stay asleep, according to the National Institute on Deafness and Other Communication Disorders. Insomnia is a different condition from sleep apnea, so your diagnosis affects which claim, if any, fits your situation.
Do you need a sleep study for a sleep apnea claim?
A confirmed diagnosis is the starting point for any sleep apnea claim, and a sleep study is the standard way to confirm it. Ask your provider whether a sleep study is right for you if you haven’t had one.
Can you claim sleep apnea directly instead of as a secondary condition?
Yes, if evidence links your sleep apnea to something that happened during service. The HealthSource guide to sleep apnea nexus letters explains direct and secondary approaches.
