What is a VA Nexus Letter and How to Get One?

A VA Nexus Letter is one of the most critical documents you’ll need when filing a VA disability claim.

It serves as a link between your current medical condition and your time in military service, helping to establish a service connection. Without a strong Nexus Letter, your chances of getting a favorable decision on your claim may diminish significantly. In this guide, we’ll explain what a Nexus Letter is, why it’s essential, and how to obtain one.

What is a Nexus Letter?

A Nexus Letter is a document written by a licensed medical professional that connects your current disability to your military service. The letter is essentially an expert medical opinion stating that your condition is “at least as likely as not” related to your time in the service. This phrase, “at least as likely as not,” is key because it establishes a 50% or greater chance that your condition was caused by or aggravated by your military service.

For many veterans, obtaining a service connection for their disability can be challenging, especially for conditions that manifest after military service. The Nexus Letter helps bridge that gap by providing a professional medical opinion that supports your claim.

Why is a Nexus Letter Important?

The VA requires a strong connection between your military service and your medical condition to award compensation. A Nexus Letter can make or break your disability claim by providing the necessary link to establish that connection.

Here’s why a Nexus Letter is important:

1. Proving a Service Connection: Many conditions, especially those that don’t have obvious, immediate symptoms during or after service (e.g., PTSD, chronic pain, or Gulf War Illness), require expert medical testimony to establish a service connection.
2. Strengthening a Claim: Even if your medical records show that you have a condition, the VA still needs to see that it’s related to your service. A Nexus Letter strengthens your claim by providing a medical professional’s opinion on the cause of your condition.
3. Secondary Conditions: If your claim involves a secondary condition (e.g., IBS secondary to PTSD), a Nexus Letter can help prove that the secondary condition was caused by or aggravated by the service-connected disability.

How to Get a Nexus Letter

Obtaining a Nexus Letter requires the assistance of a healthcare provider who understands the VA disability process. The letter must come from a licensed medical professional, such as a physician, psychologist, or specialist in the field related to your condition. Here’s how you can get a Nexus Letter:

1. Consult with Your Doctor or Specialist

Your personal doctor or a specialist treating your condition may be able to write a Nexus Letter. Be sure to discuss your medical history and how your condition is related to your military service. Your doctor should include details about:

• Your diagnosis and treatment plan
• Medical evidence linking the condition to your service
• The phrase “at least as likely as not” indicating a 50% or greater chance that the condition is service-related

Many veterans have success working with their own healthcare providers because they have a detailed medical history with them.

2. Seek a Private Nexus Letter Service

If your doctor is unwilling or unable to write a Nexus Letter, you can seek help from private services that specialize in VA disability claims. These services typically connect veterans with physicians who are familiar with VA claims and are willing to review your medical records to write a professional Nexus Letter.

Some veterans organizations or law firms specializing in VA disability claims also offer Nexus Letter services.

3. Hire a Medical Expert or Legal Professional

In complex cases, you may need to hire a medical expert or legal professional who specializes in VA disability claims. These professionals can provide not only a Nexus Letter but also additional guidance on how to strengthen your case. They can review your service treatment records (STRs), post-service medical records, and VA Compensation and Pension (C&P) exams to build a strong case for your claim.

What Should a Nexus Letter Include?

A strong Nexus Letter should include the following elements:

1. Diagnosis: A clear diagnosis of the veteran’s condition.
2. Service Connection: An explanation of how the condition is related to or aggravated by military service.
3. Medical Rationale: A detailed explanation, supported by medical evidence, of why the condition is related to service.
4. Use of VA Terminology: The phrase “at least as likely as not” should be used to state the likelihood that the condition is service-connected.
5. Credentials of the Physician: The medical provider’s qualifications, including licensing and specialization.
