Filing a VA disability claim can feel straightforward at first: identify the condition, submit the form, wait for a decision. In practice, many delays and lower-than-expected ratings trace back to a handful of avoidable problems in the record. Even with major improvements in claims processing, the VA still says the time to review a claim depends on the type of claim, the number and complexity of the conditions claimed, and how long it takes to gather the evidence needed to decide it. As of March 2026, the VA reported an average of 75.7 days to complete disability-related claims, but individual cases can take longer when development stalls or evidence is incomplete (VA claim process, VA claims process overview).
This is where small filing decisions can make a big difference.
Below are 8 common VA disability claim mistakes that can delay approval, weaken the service-connection analysis, or lead to a lower rating than the record might otherwise support. If you want a broader overview of how service connection, medical evidence, VA exams, and post-filing review fit together, it may help to start with this plain-English overview of the VA claims process.

One of the most common problems in an initial claim is assuming the VA will automatically connect a current diagnosis to military service. In general terms, a VA disability claim usually works best when the file clearly shows three things: a current disability, an in-service event/injury/disease, and a link between the two. The VA explains that this “link” often comes from medical records or medical opinions, though in some situations lay evidence such as a buddy statement may also help (VA evidence guidance).
A lot of veterans file with a diagnosis alone. That can leave a gap in the record.
For example, a claim for back pain may include treatment records from recent years, but no clear explanation of the in-service lifting injury, field accident, airborne impact, or documented symptoms during service. The same issue appears in tinnitus, migraines, orthopedic injuries, sleep-related claims, and mental health claims. The condition may be real and documented, but the connection may still be underdeveloped.
This often leads to one of two outcomes:
