VA Secondary Claims
Nexus Letter for Depression Secondary to Tinnitus
Medically reviewed by the Patriot Path Medical Team
Licensed MD reviewers • Last updated: July 2026
A nexus letter is the medical opinion that ties your depression to your service-connected tinnitus. The VA does not presume the link, so a secondary claim usually turns on this one document. It states that your depression is at least as likely as not caused or aggravated by your tinnitus, and it explains the medicine behind that conclusion. Get it right and a claim the VA would otherwise deny can be approved.
An illustrative example
Marcus came home with a 10 percent rating for tinnitus and thought that was the end of it. The ringing never stopped. It cost him sleep, then focus, then most of the things he used to enjoy.
By the time a doctor named it depression, he had been withdrawn for two years. He filed for it, and the VA denied the claim. His tinnitus was service-connected and his depression was in the record, but nothing explained why one led to the other.
A clinician then wrote a nexus letter that laid out the connection, the sleeplessness and constant intrusion of tinnitus wearing his mood down, and cited the research behind it. On the supplemental claim, the VA connected the depression to his tinnitus and paid it.
A composite example for illustration, not a real client. Outcomes depend on your own facts and evidence.
What Depression Secondary to Tinnitus Means
Most veterans picture service connection as a straight line: something happened in service, and it caused a condition. A secondary claim works differently. It connects a new condition to a disability the VA already service-connected, rather than to your service directly. The rule that allows it is 38 C.F.R. 3.310.
Depression secondary to tinnitus fits this exactly. Your tinnitus is already service-connected. Your depression came later. You are asking the VA to accept that the tinnitus caused the depression, or made it worse than it would have been on its own. Aggravation counts too: if the constant ringing pushed a mild, manageable low mood into clinical depression, that worsening is claimable.
The catch is that the VA does not assume any of this. Unlike a presumptive claim, where the link is accepted for you, a secondary claim puts the burden on the evidence. That evidence is the nexus letter.
The claim rests on your service-connected tinnitus, so that rating needs to be settled first.

How Tinnitus Can Lead to Depression
The connection is not a courtesy the VA extends. It is well documented, and it is easy to understand once you have lived with the ringing. Tinnitus is a sound that never turns off, and a body and mind that never get quiet wear down.
Sleep that never fully comes
Tinnitus is loudest when everything else is silent, which is exactly when you are trying to sleep. Broken, shallow sleep night after night is one of the most reliable drivers of depression, and it is one of the first things a strong nexus letter describes.
Constant intrusion and strain
A sound you cannot escape takes a share of your attention all day. Concentration slips, patience runs short, and the effort of tuning it out is exhausting. Over months and years, that steady strain pulls mood down with it.
Withdrawal and lost enjoyment
Many veterans pull back from noise, from crowds, from conversation, because the ringing makes them harder to bear. The isolation that follows is fertile ground for depression, and it is the piece family members usually notice first.
A documented pattern
This is not one veteran's theory. In a national study of VA users, the odds of a positive depression screen rose sharply with tinnitus severity, and reviews of the wider research find depression far more common in people with tinnitus than in those without. The VA can grant these claims when the evidence connects the two conditions.
For a nexus letter, this matters because the VA weighs opinions that explain the mechanism far more heavily than a bare assertion. A clinician who can name the pathway, from ringing to lost sleep to a mood disorder, and cite the literature writes a letter an examiner cannot easily wave away.
The same ringing drives other claims. See our guides to insomnia secondary to tinnitus and migraines secondary to tinnitus.
Can You Get VA Disability for Depression Secondary to Tinnitus?
Yes, and it is one of the more common secondary claims tinnitus supports. To win it, three things have to be in place. A nexus letter supplies the third and ties the first two together.
- 1
A current depression diagnosis
A diagnosis from a licensed clinician, made to DSM-5 criteria. Treatment notes, a mental health evaluation, or a screening in your records all help establish it.
- 2
Tinnitus already service-connected
Your tinnitus needs an existing service connection and rating. The secondary claim builds on it, so this has to be settled first.
- 3
A medical nexus opinion
A qualified opinion that your depression is at least as likely as not caused or aggravated by your tinnitus. This is the nexus letter.
The Language the VA Requires
The VA reads a nexus letter closely, and small differences in wording change how much weight it carries. A strong letter names the records reviewed, states your current depression diagnosis, confirms your service-connected tinnitus, explains how the ringing drove the depression, cites supporting research, and closes with the opinion in the exact probability language the VA requires. That standard comes from the benefit-of-the-doubt rule in 38 U.S.C. 5107(b): when the evidence is roughly balanced, the tie goes to the veteran.
Language that meets the bar
- “At least as likely as not caused or aggravated by the veteran's service-connected tinnitus” Meets the 50 percent threshold and names the secondary path. The standard to aim for.
- “More likely than not a result of the veteran's tinnitus” Exceeds 50 percent; stronger than the minimum.
Language that fails
- “May be related to the veteran's tinnitus” A possibility, not a probability. Below the standard.
- “Could be associated with hearing problems” "Could" does not meet the 50 percent bar, and vague wording invites a denial.
Do not overlook aggravation
If your low mood existed before but the tinnitus made it worse, the letter should say so directly and describe the baseline. Aggravation is its own path to service connection under 38 C.F.R. 3.310(b), and a letter that documents the worsening can win even when the depression was not caused by tinnitus outright.
What to Give Your Provider
A nexus letter is only as strong as the records behind it. Bring these so the clinician can write from evidence rather than assumption.
The core file
- Your tinnitus service-connection decisionThe VA letter or rating showing tinnitus is service-connected, with the effective date.
- A current depression diagnosisProvider notes or a mental health evaluation naming the diagnosis, ideally to DSM-5 criteria.
- Mental health treatment recordsTherapy notes, medications, and any screenings, which show the history and severity.
What strengthens it
- A personal statementIn your own words, how the ringing has affected your sleep, mood, focus, and daily life.
- A timelineRoughly when your tinnitus and your depression symptoms each began, so the clinician can line them up.
- Lay statementsShort notes from family or coworkers about the changes they have seen in you.
What VA Rating Can You Get for Depression Secondary to Tinnitus?
Once the depression is service-connected, the VA rates it under 38 C.F.R. 4.130, the General Rating Formula for Mental Disorders, at 0, 10, 30, 50, 70, or 100 percent. The level turns on how far the depression impairs your work and social life, not on the tinnitus that caused it. Many veterans who carry only a 10 percent tinnitus rating receive a substantially higher rating for the depression secondary to it.
How it adds to your combined rating
Two points matter for your combined rating. First, tinnitus stays a separate flat 10 percent under 38 C.F.R. 4.87, Diagnostic Code 6260, and the depression rating is combined with it under the VA combined-ratings table rather than replacing it (the VA combines percentages with that table, not simple addition). Second, the VA scores all of your mental health as a single rating, so if you are also service-connected for PTSD or anxiety, the depression is folded into that one mental health evaluation rather than rated on top of it.

How to File the Secondary Claim
You file depression secondary to tinnitus like any disability claim, but you present it as a secondary condition and lead with the nexus letter.
- 1File VA Form 21-526EZThe Application for Disability Compensation. Name depression as secondary to your service-connected tinnitus so the VA reviews it on that theory.
- 2Attach the nexus letterThe physician or psychologist opinion tying the depression to the tinnitus in the language above. This is the centerpiece of the claim.
- 3Include your supporting evidenceYour depression diagnosis and treatment records, your personal statement, and any lay statements from people who know you.
- 4Submit and track itFile online at VA.gov, by mail, or with a Veterans Service Officer, who can help at no cost. Keep copies of everything you send.
A Veterans Service Officer through your state or a veterans organization can file the claim with you for free. Their help is a good complement to a strong nexus letter, not a substitute for it.
What to Expect at the C&P Exam
The VA will usually schedule a Compensation and Pension exam to evaluate the depression. A VA examiner or contractor asks about your symptoms, your history, and how the condition affects your work and relationships, and then offers an opinion on severity and cause.
Bring a copy of your nexus letter and be honest and specific. Describe how the ringing disrupts your sleep and mood on your worst days, not just your average ones. A clear, consistent account that matches your records and your letter is what carries the exam.
If Your Claim Is Denied
Secondary mental health claims are often denied the first time, usually because the medical evidence did not clearly connect the two conditions or the C&P examiner disagreed. A denial is not the end of the claim.
Read the decision and the exam report to see exactly why it was denied. If the problem was a weak or missing link, a stronger nexus letter that answers the examiner's reasoning is often what turns it around. You can then file a Supplemental Claim on VA Form 20-0995 with that new evidence.
We break down the most common reasons these claims fail, and how to fix each one, in our guide to why the VA denies nexus letters.
Who Should Write the Letter, and What It Costs
Any licensed clinician can write a nexus letter, but for a mental health condition the VA gives the most weight to opinions from psychiatrists and psychologists, providers who diagnose and treat depression for a living. What sets a strong letter apart is not just the credential; it is a clinician who reviews your records, explains the mechanism, and states the opinion in the language the VA requires.
Patriot Path's physicians and psychologists write letters built for this exact claim: records reviewed, the tinnitus-to-depression connection, supporting research, and the opinion in the language the VA expects. One flat fee of $1,500, and the first consultation is free.

Frequently Asked Questions
Does the VA automatically connect depression to tinnitus?
No. There is no presumption that links depression to tinnitus, so the VA will not make the connection for you. You have to prove it, and the nexus letter is the piece of evidence that does. It states that your depression is at least as likely as not caused or aggravated by your service-connected tinnitus, and explains the medicine behind that conclusion.
Do I need my tinnitus to be service-connected first?
For a secondary claim, yes. The claim builds on an already service-connected condition, so your tinnitus needs an existing rating before depression can be tied to it. If your tinnitus is not yet service-connected, that claim comes first, and you can pursue the depression once it is settled.
Can tinnitus really cause depression?
The connection is well documented. A sound that never stops disrupts sleep, breaks concentration, and pushes many veterans into isolation, and each of those is a known driver of depression. Research finds depression far more common in people with tinnitus than in those without, and the odds rise with tinnitus severity. A nexus letter applies that evidence to your specific case.
What VA rating can I get for depression secondary to tinnitus?
The VA rates the depression under the General Rating Formula for Mental Disorders (38 C.F.R. 4.130) at 0, 10, 30, 50, 70, or 100 percent, based on how far it impairs your work and social life. Your tinnitus stays a separate flat 10 percent, so the depression rating adds to your combined rating. If you are also service-connected for another mental health condition, the VA combines them into one mental health rating.
Who can write the nexus letter?
Any licensed clinician can, but for a mental health condition the VA gives the most weight to psychiatrists and psychologists. What matters most is that the provider reviews your records, explains how the tinnitus led to the depression, and uses the exact 'at least as likely as not' language the VA requires.
What if I already had some depression before the tinnitus?
You can still claim it. Under 38 C.F.R. 3.310(b), the VA can service-connect the amount your tinnitus worsened a condition you already had. The nexus letter should describe your baseline mood and how it changed as the ringing continued, so the VA can see the aggravation rather than treating the depression as pre-existing and unrelated.
My claim was denied. Is it over?
No. Many secondary mental health claims are denied the first time, often for a weak or missing medical link. Read the decision and the C&P exam report, then file a Supplemental Claim (VA Form 20-0995) with a stronger nexus letter that answers the reason for the denial. New, relevant evidence is what reopens the claim.
What does it cost, and how do we start?
Patriot Path charges $1,500 flat for a nexus letter, and the first consultation is free. Book a consultation and a clinician will review your situation and tell you honestly whether a letter can help your depression secondary to tinnitus claim.
