Nexus Letters
Tinnitus & Hearing Loss Nexus Letter for VA Disability Claims
The ringing started somewhere between the flight line, the range, and the inside of a Bradley. Nobody handed out earplugs that fit, and nobody wrote it down.
Tinnitus is the single most claimed service-connected disability in the country, with more than three million veterans compensated for it. Hearing loss sits right behind it. And yet these claims are denied constantly, usually for one reason that sounds authoritative and is legally wrong: your audiogram was normal when you separated.
A nexus letter for tinnitus or hearing loss exists to answer that argument with medical reasoning. Nexus Veteran MD prepares evidence-based opinions for veterans and the attorneys representing them.
What a Nexus Letter Does for a Hearing Claim
A nexus letter is a written medical opinion connecting your current condition to your military service. For auditory claims, it typically establishes that your documented noise exposure in service is at least as likely as not the cause of your tinnitus, your hearing loss, or both — the 50%-or-greater probability standard VA applies when weighing evidence.
The letter is not a hearing test and does not replace one. It is the interpretive layer that explains what the testing means in the context of your service history.
Why These Claims Get Denied
Tinnitus and hearing loss denials follow a predictable script. Understanding it tells you exactly what your nexus letter has to overcome.
“Hearing was within normal limits at separation.” This is the most common denial rationale and the most vulnerable to rebuttal. The Court of Appeals for Veterans Claims addressed it directly in Hensley v. Brown: normal hearing at discharge does not bar service connection if hearing loss is later shown to be related to service. An examiner who stops at the exit audiogram has not actually answered the question.
“No significant threshold shift during service.” Standard audiograms test a limited frequency range and measure only one kind of damage. Noise exposure can injure the cochlear nerve synapses while pure-tone thresholds still read as normal — a pattern sometimes called hidden hearing loss. Difficulty understanding speech in a crowded room with a “normal” audiogram is a familiar presentation, not a contradiction.
“Delayed onset means another cause is more likely.” Noise-induced auditory damage is cumulative and often becomes clinically apparent years after the exposure that caused it. A gap between discharge and diagnosis is not evidence against causation, but examiners treat it that way unless someone explains otherwise.
“No documented noise exposure.” Very few service treatment records say “exposed to loud noise today.” VA’s own Duty MOS Noise Exposure Listing assigns probability of hazardous noise exposure by military occupational specialty, and a properly built opinion cites it alongside your DD-214 and personnel records.
What VA Requires
Service connection for either condition requires three elements:
- A current diagnosis. For tinnitus, this rests largely on your own credible report — you are competent to describe ringing in your own ears, and no objective test is required. For hearing loss, VA applies a specific regulatory threshold.
- An in-service event or exposure, typically hazardous noise, acoustic trauma, blast exposure, or ototoxic medication.
- A medical link between the two.
On the second element, note that 38 CFR 3.385 defines when hearing impairment counts as a disability for VA purposes: an auditory threshold of 40 dB or greater at 500, 1000, 2000, 3000, or 4000 Hz; thresholds of 26 dB or greater at three of those frequencies; or speech recognition scores under 94% using the Maryland CNC test. Hearing loss that falls short of this threshold is real, but VA will not compensate it — which is one reason accurate testing and documentation matter so much.
Sensorineural hearing loss and tinnitus may also qualify as presumptive conditions if they manifested to a compensable degree within one year of separation, as chronic organic diseases of the nervous system under 38 CFR 3.309(a).
What a Strong Tinnitus or Hearing Loss Nexus Letter Contains
- Provider credentials appropriate to auditory conditions.
- A stated list of records reviewed — service treatment records, entrance and separation audiograms, personnel file, MOS and duty assignments, post-service audiology, and any prior C&P exam.
- The specific noise exposure history, described concretely: weapons systems, aircraft, engine rooms, generators, artillery, armor, blast events.
- The current diagnosis, with audiometric findings where applicable.
- A medical rationale that directly addresses the denial logic above — why a normal separation audiogram does not rule out service causation, why delayed onset is consistent with noise injury, and why alternative causes are less likely.
- The probability statement: at least as likely as not.
- Signature, date, and contact information.
The rationale is the whole ballgame. A one-paragraph letter saying “in my opinion this is related to service” gives a rater nothing to weigh and is routinely set aside.
Secondary Claims Involving Tinnitus and Hearing Loss
These conditions rarely travel alone, and secondary service connection requires its own nexus opinion.
Tinnitus is commonly claimed secondary to hearing loss, traumatic brain injury, Meniere’s disease, or ototoxic medication taken for another service-connected condition. Moving in the other direction, chronic tinnitus frequently causes or aggravates insomnia, depression, anxiety, migraines, and concentration difficulty — each of which can be claimed as secondary to the tinnitus itself.
If you already carry a 10% tinnitus rating, the secondary claims are usually where the meaningful compensation is.
How VA Currently Rates These Conditions
Tinnitus is rated under 38 CFR 4.87, Diagnostic Code 6260, at a flat 10% — the same whether it affects one ear, both ears, or is perceived in the head. There is no higher schedular rating for tinnitus alone. In 2022 VA proposed deleting DC 6260 and compensating tinnitus only as a symptom of an underlying condition. As of this writing that proposal has not been finalized, and the standalone 10% rating remains in effect.
Hearing loss is rated under Diagnostic Code 6100 on a scale from 0% to 100%, using tables that combine puretone threshold averages with Maryland CNC speech discrimination scores. Ratings are mechanical: the numbers from the audiogram determine the outcome, which is why testing conditions and examiner accuracy matter enormously.
Working With Nexus Veteran MD
Submit your records for review. A qualified medical professional evaluates your service history, audiometric evidence, and exposure profile against VA’s standards, then determines whether a supportable opinion can be written. If the evidence supports it, we prepare a detailed letter with full rationale addressing the specific reasoning likely to appear in your denial. If it doesn’t, we tell you plainly.
Pair the opinion with a completed Disability Benefits Questionnaire, and see our main nexus letter page for how the service works across conditions.
Frequently Asked Questions
Can I get service-connected for tinnitus with a normal hearing test?
Yes. Tinnitus is rated independently of hearing acuity, and documented hearing loss is not required under the current diagnostic code.
My separation audiogram was normal. Is my claim dead?
No. Hensley v. Brown established that normal hearing at discharge does not preclude service connection when current hearing loss is medically linked to service. This is precisely the argument a well-reasoned nexus letter is built to address.
Do I need a nexus letter if my MOS obviously involved noise?
Not always. If your MOS carries a high probability of hazardous noise exposure and the record is clean, VA may concede the connection. Nexus letters matter most after a denial, after an unfavorable C&P opinion, or where the exposure isn’t obvious from your records.
Who can write it — an audiologist or a physician?
Either may be appropriate depending on the claim. What VA weighs is whether the provider’s expertise fits the question and whether they demonstrably reviewed the file.
Will the proposed tinnitus rule change affect my claim?
It is not final. Veterans already service-connected are generally protected under 38 CFR 3.951. Filing under current criteria while they remain in effect is the practical approach.
Can I claim both tinnitus and hearing loss?
Yes. They are separate diagnostic codes and are rated separately, which is why many veterans pursue both together.
