Tinnitus Secondary to Hearing Loss Claim Guide

We analyzed the Board's published decisions and found tinnitus (DC 6260) claimed as secondary to hearing loss (DC 6100) is a real, mid-sized claim pool that wins clearly more often than it loses once it reaches a merits decision.

How those 1,422 issues came out

The ICD-10 diagnosis codes most commonly used for DC 6260, Tinnitus (the kind on your medical records, decision letter, or C&P exam report). VA rates the disability and its residuals, not the diagnosis itself, so coding can vary.

See the full diagnostic-code page →

Under 38 CFR 3.310 a secondary claim turns on three elements:

• A current diagnosis: a medical diagnosis of tinnitus (the secondary).
• A service-connected primary: Hearing Loss, already service-connected (the primary). A 0% primary still counts.
• A medical nexus: a medical opinion linking the tinnitus to the hearing loss, showing the primary caused or aggravated it.

See the Secondary Claim guide for the caused-versus-aggravated split, and the Nexus Letter guide for what makes the medical opinion strong.

Whether that medical link exists in any one case is a medical question decided on that case's own evidence (the nexus).

The outcome split above counts whole issues. This section goes one layer deeper. Under 38 CFR § 3.310 a secondary claim can be won two ways: the hearing loss caused the tinnitus (§ 3.310(a)), or it aggravated an existing tinnitus (§ 3.310(b)). Every grant rests on one or the other, so the numbers below divide up the granted claims only.

Direct causation is the route that carries most grants here: 98% of them found the hearing loss caused the tinnitus, the rest found aggravation. A practical consequence for the nexus opinion: it should address both routes, because a medical opinion that only argues causation leaves the aggravation theory, a separate legal basis, on the table. See the caused-vs-aggravated guide for how the two theories differ.

On the other side: in 37 denied claims the Board looked at this pairing and found no link, meaning it decided the hearing loss neither caused nor worsened the tinnitus. That is a separate group from the grants above, counted here so the picture is not one-sided.

We analyzed published Board decisions on this pairing to build this split. The grant split covers granted claims only; denied, remanded, and dismissed claims are not in it. Descriptive of the published record, not a prediction.

The record VA actually reviews centers on a small set of documents. We analyzed published Board decisions on these claims and ranked the records that appeared most often:

• A medical nexus opinion: the one record VA weighs most on a secondary claim, a doctor's statement linking your tinnitus to your service-connected hearing loss and naming the mechanism.
• Ringing reported since service
• Lay testimony accepted as competent for tinnitus
• Duty-MOS noise exposure conceded or highly probable
• Audiology opinion addressing tinnitus

The diagnostic code involved: DC 6260 (Tinnitus). The rating levels for this code are in the rating section below.

Records ranked by how often published Board decisions cited them. The exam that captures most of this is covered in the C&P Exam section below. Source: Board of Veterans' Appeals decisions, RateMyVSO analysis.

What veterans who win this pairing actually put in the file, and why each piece moves the claim.

• Your current VA audiogram with tinnitus noted: Get a recent hearing test that includes the Maryland CNC speech test (the VA's standard) and make sure the report notes your tinnitus in the same visit. Having both problems documented together on one test is strong proof they are connected.
• Your hearing loss rating decision: Pull the VA decision letter that already granted you service connection for hearing loss. A secondary claim only works if the first condition is already approved, so this paper is the doorway that lets the tinnitus claim in.
• The nexus letter (your most important document): Ask an audiologist, ENT doctor, or physician to write a letter stating your tinnitus is "at least as likely as not" caused by the same inner ear damage as your hearing loss. Have them name the shared cause: damage to the tiny hair cells in the cochlea from noise, blast, or certain medications damages both hearing and creates the ringing at the same time. Vague words like "may" or "could" hurt you. The letter needs to say it plainly.
• Rule out other causes in that same letter: This is where claims get denied. VA raters look for any other explanation, like age, a civilian job, or a medication you took after leaving service, and use it to deny the claim. Have your doctor's letter specifically address your military noise exposure (weapons, aircraft, machinery, blast events) and explain why that exposure, not something else, is the more likely cause.
• Form 21-4274-1, the tinnitus questionnaire: This VA form has your audiologist document whether the ringing is constant or comes and goes, which ear, and when it started. Fill it out carefully. VA examiners expect to see it and use it to decide if your tinnitus counts as a real, ongoing disability.
• Your own written statement: Tinnitus cannot be measured on a machine the way hearing loss can. Your description matters as evidence on its own. Write down when the ringing started, what it sounds like, and whether it is there all the time. If it began after a specific event (a blast, a loud shift on the flight line), say so by name and date.
• Statements from people who knew you back then: A spouse, buddy, or coworker who remembers you complaining about ringing ears, in service or soon after, backs up your story. This matters most if your service records never mention it. Ringing ears often go unreported at the time, and a witness statement helps explain the gap.
• If a VA exam already denied you, do not let it stand: Some examiners wrongly claim tinnitus can happen with no hearing loss connection, or that no mention of it in your service file means it is not related. Both claims go against well-established hearing science. Bring this up with your doctor when you request the nexus letter, and ask them to directly address and correct the examiner's reasoning.

These five Board decisions show a consistent pattern for tinnitus claimed as secondary to hearing loss. In each case, a VA examiner had already found a current diagnosis of hearing loss and tinnitus, and gave a short opinion stating that tinnitus is a symptom commonly associated with hearing loss. The Board accepted this kind of brief opinion as enough to grant the secondary claim, even where the same examiner had denied a direct link to service. Board decisions like these are not binding precedent on other veterans' claims, but they show how the Board has approached this specific pairing.

The VA assigns one of these percentages based on what your medical record documents. Plain-language summary of the rating criteria at 38 CFR; the controlling text is the regulation itself.

Every item below comes from a pattern in the decisions on this pairing, not from general claim advice.

For the mechanics of filing itself, see the Standard Claim Guide and the Fully Developed Claim Guide.

A secondary claim moves through the same pipeline as any other. Understanding who does what helps you know who to contact and what to expect.

1. You file the claim, naming Hearing Loss as the service-connected primary and tinnitus as secondary. Directly with VA, through VA.gov, or with an accredited representative's help.
2. VA assigns a Veteran Service Representative (VSR) to develop the claim: gather your service treatment records, VA and private medical records, and order a C&P exam if needed.
3. The C&P exam is conducted, usually with the examiner asked to address the specific secondary theory (causation and aggravation both).
4. The file goes to a Rating Veteran Service Representative (RVSR), the "rater," who weighs the medical evidence and decides service connection and, if granted, the rating percentage.
5. VA issues the decision letter stating the outcome and the reasoning.
6. If denied or under-rated, you choose an appeal lane, Supplemental Claim, Higher-Level Review, or a Board appeal, covered below.

For the full walkthrough, see Inside Your Claim and Claim Stages.

A Disability Benefits Questionnaire (DBQ) is the standardized form the examiner completes for your condition. See the DBQ Guide for how these forms work and whether a private DBQ from your own doctor can be submitted instead of relying solely on a VA exam. For what to expect and how to prepare, see the C&P Exam Prep Guide, and be specific about how your tinnitus symptoms relate to your hearing loss timeline, treatment, and any aggravation, that is the detail a nexus opinion relies on.

Your decision letter has a narrative "reasons and bases" section and a codesheet with the rating and effective date. See the Reading Your Decision Letter Guide or use the Letter Interpreter tool to decode your own letter. If denied, you have three main lanes:

• Supplemental Claim: refile with new and relevant evidence, such as a nexus opinion that addresses the mechanism and the specific VA rationale you're rebutting. See Supplemental Claim Guide.
• Higher-Level Review (HLR): a senior reviewer looks at the same evidence again, useful if the denial rested on a legal error. See HLR Guide.
• Board Appeal: your case goes to a Veterans Law Judge, with a direct review, evidence, or hearing docket. See Board Appeal Guide.

Keep documentation of ongoing treatment, follow-up evaluations, and any updated diagnostic testing for your tinnitus on file, this protects you if VA schedules a future reexamination. See Protect Your Rating for when a rating becomes protected and Future Reexaminations for what triggers one. If your tinnitus worsens, see the Rating Increase Guide.
