Secondary service connection

Conditions secondary to hearing loss

Veterans with service-connected hearing loss often claim other conditions as caused or worsened by it. This page lists those conditions, what VA needs to grant them, and how they fared when veterans appealed to the Board of Veterans' Appeals.

What VA needs to grant a secondary claim

Secondary service connection means VA disability benefits for a condition caused or made worse by a disability that is already service connected (38 CFR 3.310). The claim needs three things:

  1. A current diagnosis of the secondary condition.
  2. Hearing loss is already service connected.
  3. Medical evidence linking them (a nexus opinion): the secondary condition was caused by hearing loss (3.310(a)), or was made worse beyond its natural progress by it (aggravation, 3.310(b)).

VA's procedures for these claims are in M21-1 V.ii.2.D. When the evidence for and against is about even, VA must decide in the veteran's favor (38 CFR 3.102).

Conditions claimed secondary to hearing loss

Conditions the Board decided at least 300 times as secondary to this disability, highest appeal grant rate first. Open one for the evidence and reasons behind the decisions.

Hearing loss claimed secondary to other conditions

The other direction: hearing loss claimed as caused or worsened by a different service-connected disability.

Tinnitus secondary to hearing loss wins far more often than the reverse

At the Board, tinnitus claimed secondary to hearing loss was granted in 65.6% of 1,456 decisions, while hearing loss claimed secondary to tinnitus was granted in only 13.5%.

Tinnitus secondary to hearing loss vs primary connection

Hearing loss across all theories was granted in 20.5% of 91,802 decisions and denied in 44.8%. The reverse pairing mostly ends in remand, with 67.8% of those issues sent back. When the Board reached the merits, it granted tinnitus secondary to hearing loss in 89.9%, against 41.9% for the reverse. The most cited tinnitus grant reason was causation by the service-connected disability, in 212 decisions.

Service connection for noise exposure and the C&P exam

For hearing loss overall, conceded in-service noise exposure was the top grant reason, named in 2,898 decisions. Combat service appeared in 7,963 decisions, granted at 47.6% versus 29.7% without it. A favorable VA exam went with a 47.7% grant rate, against 28.5% without one. A negative VA examiner opinion was cited in 3,641 denials, behind no current diagnosis at 4,002. The data does not show why these factors line up with outcomes.

Buddy statements and lay evidence impact

Buddy statements appeared in 2,205 hearing loss decisions, granted at 44.4% versus 31.1% without. General lay statements were far more common, in 77,051 decisions, and showed almost no gap: 31.5% with versus 30.8% without. For hearing loss secondary to tinnitus, decisions with lay statements were granted at 37.4% versus 78.6% without. The data does not show why that gap runs the other way.

Rating schedule and appeals for underrated claims

The Board decided 32,889 hearing loss rating issues, granting 9.7% and denying 58.6%. Criteria for a higher rating not met was the top denial reason, in 7,160 decisions. Under DC 6100, the Board granted 7.6% of 5,245 issues on the merits. Across all hearing loss rating grants, ratings of 10 percent were the largest share at 33.0%, while 100 percent ratings made up 4.5%.

Where this data comes from

  1. Claim
  2. Regional office decides
  3. Veteran appeals
  4. Board decides
  5. Granted · Denied · Remanded: back to the regional office

Board of Veterans' Appeals decisions show how VA's highest review body applies 38 CFR and weighs evidence on contested claims.

Each one is an appeal: a regional office decided the claim first, and the veteran appealed. So these rates describe the Board, not a veteran's odds at the regional office, where most claims are decided and whose decisions are not public.
