If you're a veteran, you've probably heard all about nexus letters and DBQs – but what's the deal? What are they, and what do they really do for your claim? We'll cover the basics in this blog so that you can stay informed about what makes the most sense for you VA disability benefits claim.
Here's what veterans should know about nexus letters, DBQs, and the differences between the two:
What are nexus letters?
A nexus letter is a medical opinion document that is used to connect your condition to your time serving in the military or to another service-connected condition.
This is an official medical opinion that is written by a licensed and qualified medical provider, such as your doctor or a private medical evidence provider (like us). Learn more about choosing a private medical evidence provider here.
How can nexus letters help your VA disability benefits claim?
Many veterans submit claims with confirmed diagnoses, treatment records, and even documentation of their symptoms during or after service.
But the thing is…
If your claim doesn't clearly illustrate how your time spent in the military is the direct cause or significant contributing factor to the condition, the VA won't give you VA disability.
You need a medical nexus in order to get benefits (a link between your condition and your military service). Read more about medical nexuses here.
This is what a nexus letter makes crystal clear for the VA. A good nexus letter does all of the following things:
It clearly explains how the condition is connected to service
It walks through the medical reasoning step by step
It includes and references relevant medical records
It is clear, concise, and easy to follow
What are DBQs (Disability Benefits Questionnaires)?
DBQ stands for "disability benefits questionnaire" – this is a VA form that answers questions about your medical condition. The questions primarily focus on the medical workup for your condition, highlighting the severity. DBQs are often used in relation to rating levels for a given condition.
The VA has published public facing DBQ's that your doctor or private medical companies can complete for you to submit with your claim. The VA has a slightly different version for their internal use when requesting C&P exams.
Like nexus letters, DBQs that are privately written are widely accepted by the VA.
How can DBQs help your VA disability benefits claim?
A good DBQ gives the VA a clear picture of your condition, including past medical history and a full range of symptoms. So, how's it different from a nexus letter?
Think of the difference between nexus letters and DBQs like this:
Nexus letters connect your condition to your time spent in the military.
DBQs document the severity and symptoms of your condition.
This is why the combination of a nexus letter plus DBQ is a game changer for your VA disability benefits claim.
The DBQ forms contain sections to talk about your medical history, functional history, and elaborate on some testing performed, but the space is limited and often there is not enough room to really communicate how the condition is connected to service. This is why we and many other companies provide a separate more detailed nexus letter to really tell your story.
