Free Nexus Letters for Veterans.AI-Generated. Backed by Medical Research.
The VA needs a medical opinion connecting your condition to your service. Our AI cites real medical journal articles to build that connection—so your doctor can review it, sign it, and you can file it.
What Is a Nexus Letter for Veterans?
A nexus letter is a medical opinion from a licensed provider that connects your current condition to your military service. It tells the VA your disability is “at least as likely as not” related to service—the standard required for service connection.
When You Need a Nexus Letter
- Weak service records — your military medical records don't fully document your condition
- Secondary conditions — connecting a new condition to an existing service-connected rating
- Mental health claims — PTSD, anxiety, depression that may not have been documented during service
- Delayed conditions — conditions that developed years after service ended

Frequently Asked Questions
Have a question not listed here? Reach out to us
What is a Nexus Letter?
A Nexus Letter is a medical opinion from a licensed healthcare professional that establishes a connection ('nexus') between your current disability and your military service. It states that your condition is 'at least as likely as not' (50% or greater probability) related to service—the standard of proof the VA requires for service connection.
Why do I need a Nexus Letter?
Without a nexus letter, the VA may not be able to connect your condition to your service—even if the connection seems obvious to you. Nexus letters are especially important when service records are incomplete, for secondary conditions, for mental health claims like PTSD, and for conditions that developed years after service.
How much does a nexus letter cost?
Traditional nexus letters from private doctors cost $500–$1,500+ per letter. VeteranAI generates comprehensive, research-backed letters starting with our free plan. Our AI creates the letter; your provider reviews and signs it.
Does a doctor need to sign my nexus letter?
Yes. The VA requires that a qualified healthcare provider (MD, DO, NP, PA, or psychologist for mental health) review and sign the letter. VeteranAI creates the letter with all the research and formatting—your provider just needs to review and sign.
Can I get a nexus letter for secondary conditions?
Yes. Secondary conditions—disabilities caused or worsened by an already service-connected condition—are one of the most common uses for nexus letters. For example, sleep apnea secondary to PTSD, or hip problems secondary to a service-connected knee injury.
How long does it take to generate a nexus letter?
Our AI generates a complete nexus letter within minutes. You can download it immediately and bring it to your healthcare provider the same day.
