A nexus letter for tinnitus is a medical opinion that explains whether the ringing, buzzing, or hissing you hear is at least as likely as not connected to noise you were exposed to in service. If your service records show loud noise but no ear complaints, or your symptoms started years later, a well-reasoned opinion can help fill that gap. It is one piece of evidence, and VA weighs it alongside everything else in your file.
Key takeaways
- Tinnitus and hearing loss have been the two most common service-connected disabilities among veterans for more than a decade, largely because of military noise exposure.
- VA generally needs three things for service connection: a current condition, an in-service event or exposure, and a medical link between the two.
- Before you request a nexus letter, gather your service records, any hearing tests, and a written statement describing your noise exposure and when the ringing began.
What is tinnitus?
Tinnitus is hearing a sound that has no outside source, so other people cannot hear it. According to the National Institute on Deafness and Other Communication Disorders (NIDCD), it is most often described as ringing, though some people hear roaring or buzzing, and it is considered chronic (long-lasting) when it continues for three months or more.
Tinnitus is usually a symptom of something else. The Mayo Clinic notes that it can be linked to more than 200 different health conditions, with hearing loss from age or loud noise among the most common causes. Other possible contributors include:
- Loud noise exposure, such as firearms and heavy machinery, which can damage the tiny hair cells in the inner ear
- Certain medications, including some anti-inflammatory drugs, antibiotics, and diuretics
- Ear problems, such as earwax blockage, ear infections, or jaw joint (temporomandibular joint, or TMJ) disorders
- Head or neck injuries, including traumatic brain injury (TBI)
- Blood vessel conditions, such as high blood pressure, which more often cause a pulsing sound
The NIDCD estimates that 10 to 25% of adults experience tinnitus. There is no cure, but sound therapy, hearing aids, and counseling such as cognitive behavioral therapy can reduce its impact.
Why is tinnitus so common among veterans?
Tinnitus is common among veterans because military service often involves repeated exposure to very loud noise. The NIDCD describes tinnitus as the most common service-related disability among veterans, largely due to gunfire, machinery, and blasts.
Research backs this up. A review of the U.S. military experience reports that noise-induced tinnitus and hearing loss have been the top two service-connected disabilities for veterans receiving compensation for more than a decade, and that veterans are about twice as likely as non-veterans to have tinnitus. In a study of more than 758,000 veterans in the VA Million Veteran Program, about 37.5% reported tinnitus, had it diagnosed, or both. The researchers found that traumatic brain injury and daily combat noise exposure carried more risk than age alone.
A systematic review of service members deployed to Iraq and Afghanistan also points to blasts and high noise levels as hazards. Even so, VA decides each claim on its own evidence.
How does direct service connection work for tinnitus?
Direct service connection means showing that your tinnitus began in, or was caused by, your time in service. According to VA’s guidance on evidence, VA generally looks for three things:
- A current condition. You currently have tinnitus.
- An in-service event or exposure. For tinnitus, this is usually hazardous noise during active duty.
- A link (nexus). Evidence connecting your current tinnitus to that in-service exposure. VA usually relies on medical records or medical opinions for this part.
Federal regulations allow service connection even when a condition is first diagnosed after discharge. Under 38 CFR 3.303(d), VA may grant service connection for a disease diagnosed after separation when all the evidence shows it was incurred in service. This matters for veterans who never mentioned ringing on their separation exam.
How VA looks at noise exposure by job
VA’s adjudication guidance includes a Duty Military Occupational Specialty (MOS) Noise Exposure Listing, which estimates how likely noise exposure was for different military jobs. In one Board of Veterans’ Appeals decision, for example, the Board noted that a veteran’s job had been found by the Department of Defense to involve a moderate probability of noise exposure, citing VA’s adjudication manual. Your job title, duties, training, and deployments can all help show exposure.
If you’ve already gathered your records and want a physician to review whether your history supports a connection, a VA independent medical opinion through HealthSource starts with a video appointment and a review of your documents.
Why your own description of tinnitus counts
Because tinnitus is something only you can hear, your own description is important evidence. VA regulations define competent lay evidence (testimony that does not require medical training) as evidence from a person with knowledge of facts that can be observed and described by a lay person, according to 38 CFR 3.159(a)(2).
The Board has applied this to tinnitus directly. In a 2018 decision, the Board cited case law for the point that a layperson is capable of observing tinnitus. In a 2022 decision, the Board gave no weight to a VA opinion that relied on the absence of service treatment records and disregarded the veteran’s own statements about symptoms in and since service.
You can submit your statement on plain paper, on a Lay or Witness Statement (VA Form 21-10210), or on a Statement in Support of Claim (VA Form 21-4138), according to VA. Statements from people who served with you or noticed changes at home (buddy statements) can help too. A useful statement covers:
- What you were exposed to, such as weapons fire, aircraft, generators, or engine rooms
- Whether you had hearing protection, and how often it was available or used
- When you first noticed the ringing, and whether it has been constant or comes and goes
- How it affects you now, including sleep, concentration, or work
Once your lay evidence is in place, the medical opinion is what ties it together.
What should a nexus letter for tinnitus include?
A strong tinnitus nexus letter explains, in plain medical reasoning, why the physician believes your tinnitus is or is not related to service. If you’re new to these opinions, the guide on what a nexus letter is for a VA claim covers the basics. For tinnitus specifically, the letter should include:
- Records reviewed. A clear list of what the physician looked at, such as service treatment records, separation exams, personnel records showing your job, post-service hearing tests, and your lay statements.
- Your noise exposure history. In-service exposure in specific terms, plus any post-service noise from work or hobbies.
- A current diagnosis. Confirmation that you currently have recurrent tinnitus, along with any related findings such as hearing loss.
- An opinion using VA’s standard. A statement that it is “at least as likely as not” (a 50% or greater probability) that your tinnitus is related to service, or a clear statement that it is not.
- A rationale. The reasoning behind the opinion, drawing on your history and medical literature. In the 2018 decision above, the Board directed that a clear rationale be provided for all opinions expressed.
- Delayed onset and other noise. If the ringing started after discharge, or you had noisy civilian jobs, a careful opinion addresses that directly instead of ignoring it.
The “at least as likely as not” standard ties into VA’s benefit-of-the-doubt rule. Under 38 CFR 3.102, when the positive and negative evidence is in approximate balance, VA resolves the doubt in the veteran’s favor. A physician can only give an honest opinion based on the evidence, and VA makes the final decision.
How does VA rate tinnitus?
VA rates recurrent tinnitus at a single 10% rating, whether you hear it in one ear, both ears, or in your head. This comes from 38 CFR 4.87, Diagnostic Code 6260, which as of October 2026 lists recurrent tinnitus at 10% with these notes:
- One rating only. VA assigns a single evaluation, so you will not receive separate ratings for each ear.
- Combining with other codes. A tinnitus rating may be combined with ratings for conditions such as hearing loss, unless the tinnitus is already supporting the rating under that other code.
- Objective tinnitus is rated differently. If others can hear the sound and it has a definable cause, VA rates it as part of the underlying condition.
In 2022, VA proposed changes that would rate tinnitus as part of its underlying condition instead of on its own. The proposal stated that veterans already rated under Diagnostic Code 6260 would not be affected. Rating rules can change, so check the current regulation or ask an accredited representative before filing.
Tinnitus and related conditions
Tinnitus rarely exists in isolation. The Mayo Clinic lists fatigue, sleep problems, trouble concentrating, anxiety, depression, and irritability among its possible complications, and Johns Hopkins Medicine notes that stress may make tinnitus worse.
- Hearing loss. Hearing loss and tinnitus often appear together. The Million Veteran Program study found veterans with hearing loss were about four times as likely to have tinnitus.
- Sleep. Many people with tinnitus report trouble falling or staying asleep, especially in quiet rooms.
- Anxiety and depression. In some people, ongoing tinnitus contributes to distress, anxiety, or depression.
Whether any of these could be claimed alongside tinnitus depends on your history and needs its own medical review.
If tinnitus is affecting your mood or you are having thoughts of harming yourself, help is available now. Call or text the 988 Suicide & Crisis Lifeline at 988, or reach the Veterans Crisis Line by dialing 988 and pressing 1, or texting 838255.
Where to get help with your claim
Filing the claim and handling appeals are separate from the medical opinion. According to VA, accredited representatives include Veterans Service Organization (VSO) representatives, claims agents, and attorneys, and help from an accredited VSO representative is always free. You can use VA’s tool to find an accredited representative and confirm accreditation before you begin.
You may also be scheduled for a VA compensation and pension exam. Knowing what to expect at a C&P exam can help you describe your noise exposure and symptoms clearly.
When to seek medical attention
Ongoing tinnitus deserves a medical evaluation, and some symptoms need prompt care. According to the Mayo Clinic, see a doctor promptly if tinnitus comes with:
- Sudden hearing loss or dizziness
- Numbness or weakness in the face, arm, or leg
- Anxiety, depression, or sleep problems related to the sound
Tinnitus that starts after a car accident or a head injury calls for emergency care.
Frequently asked questions
Do I need a nexus letter for a tinnitus claim?
Not always. If your records show noise exposure and a VA examiner gives a favorable opinion, an outside letter may not be needed. A private opinion is often considered when records are thin, onset was delayed, or a VA opinion ignored your statements.
Can tinnitus be service connected if it started after I left the military?
It can. Under 38 CFR 3.303(d), VA may grant service connection for a condition first diagnosed after discharge when the evidence shows it was incurred in service. A nexus letter should explain the delay and address any post-service noise.
Does VA rate tinnitus higher if both ears are affected?
No. Diagnostic Code 6260 provides a single 10% rating for recurrent tinnitus whether it is heard in one ear, both ears, or in the head. Hearing loss, if present, is evaluated separately.
Do I need a hearing test for a tinnitus nexus letter?
Tinnitus is diagnosed largely from your own report. Still, a hearing test (audiogram) can show related hearing loss and give the physician a fuller picture, so include any results you have.
Does a nexus letter mean my claim will be approved?
No. A nexus letter is one piece of medical evidence. VA reviews all the evidence in your file and makes the final decision.
