The 3 Things Every VA Service-Connection Claim Needs (and Which One Breaks Yours)
If you've been denied "service connection," you're dealing with the most common issue at the Board: service connection is the benefit at issue in 2,302,001 of the 4,365,380 issues the Board of Veterans' Appeals decided from 1992 to July 2026 (Board outcome rates). The good news: direct service connection is just three pieces. Once you know which piece broke, you know exactly what to fix.

The three elements (Shedden / Caluza)
To win direct service connection, the law (Shedden v. Principi, Caluza v. Brown) requires all three:
- A current diagnosed disability. Something a doctor has diagnosed now. Pain alone used to fail here — but after Saunders v. Wilkie, functional loss from pain can qualify.
- An in-service event, injury, or disease. Something that happened during service — an injury, exposure, illness, or stressor.
- A medical nexus linking #1 to #2 — a doctor saying your current condition is "at least as likely as not" related to the in-service event.
Which element breaks — and what the numbers do show
VetAid hasn't measured how often each element is the reason a claim fails. It has measured how much a nexus opinion matters: across single-issue Board decisions from 1992–2024, the issue was granted 60% of the time when a medical source gave a positive nexus opinion (23,725 of 39,858 decided on the merits), versus 33% without one (152,615 of 466,524). Source: What evidence wins at the Board.
The nexus is the element most within your control — many veterans are denied not because they're wrong, but because no doctor has put the link in writing in the "at least as likely as not" language the VA requires.
How to shore up each element
- Current disability: Get a current diagnosis in your records — VA treatment, private doctor, or a DBQ.
- In-service event: If it's not in your service treatment records, a lay or buddy statement is competent evidence that it happened. You don't need a record for everything.
- Nexus: A nexus letter (or independent medical opinion) that uses the magic words — "at least as likely as not (50% or greater) related to" — and explains the medical rationale.
Read your denial letter's "Reasons for Decision." The VA almost always tells you which element it found missing. Fix that element specifically — adding more evidence for an element you already proved won't change the outcome.
Frequently Asked Questions
A current diagnosed disability, an in-service event or injury or disease, and a medical nexus linking the two. All three are required for direct service connection under Shedden v. Principi.
Service connection is the most common benefit at issue in Board appeals: 2,302,001 of the 4,365,380 issues the Board decided from 1992 to July 2026 (VetAid's Board outcome rates). The denial will name which of the three elements was missing: a current disability, an in-service event, or the medical nexus.
Not always. Lay statements from you or people who served with you are competent evidence that an event happened, especially for things like injuries, exposures, or symptoms that wouldn't necessarily be documented.
A written medical opinion stating your current condition is 'at least as likely as not' related to your service, with a supporting rationale. It's the single most effective way to fix a 'no nexus' denial.
