What Is a Nexus Letter?
A Nexus Letter is a medical opinion from a licensed physician that connects your current disability to your military service. It's often the missing piece that makes or breaks a VA claim.

A physician reviews your records and provides a professional medical opinion on the connection between your condition and service.
Evidence-Based
Backed by medical research, case law precedent, and thorough review of your service and medical history.
Strengthens Your Claim
Provides the medical nexus (connection) that helps the VA understand why your condition was caused by service.

Frequently Asked Questions
Everything you need to know about Nexus Letters and our process
What is a Medical Record Review and why do I need one?
A Medical Record Review is an evaluation of your medical documentation by our team. We assess whether your records contain sufficient evidence for a Nexus Letter and identify any gaps. This ensures you only purchase a Nexus Letter if it will actually strengthen your claim.
How much does a Nexus Letter cost?
Nexus Letters start at $795, with quantity discounts available if you need more than one. Claim Climbers uses transparent flat-rate pricing, so you keep 100% of any future benefits increase. Financing is also available through Klarna and Affirm, including Pay in 4 and longer-term payment plans.
How long does it take to get my Nexus Letter?
We start the process with a Medical record review. After we have confirmed you have provided us all of the records we need, it is completed on average of 3-5 business days. Most Nexus Letters are completed within 7-10 business days.
Will a Nexus Letter guarantee my claim is approved?
No service can guarantee VA claim approval. A Nexus Letter provides strong medical evidence, but the VA makes the final decision based on your entire claim file. Our goal is to give you the best possible medical documentation to support your case.
What makes a good Nexus Letter?
A strong Nexus Letter includes: detailed review of your service and medical records, clear medical reasoning with pathophysiology, specific medical citations and research, reference to VA case law and precedent, and a clear opinion on the connection between your condition and service (usually expressed as "at least as likely as not").
Can I use a Nexus Letter for an appeal?
Yes! Nexus Letters are commonly used for appeals, Higher-Level Reviews, and Supplemental Claims. They provide the new and relevant evidence the VA needs to reconsider a previously denied claim.
What if my condition isn't service-connected directly?
We specialize in secondary service connection, where a current condition is caused or aggravated by an already service-connected disability. For example, sleep apnea secondary to PTSD, or depression secondary to chronic pain.
Are your physicians licensed and qualified?
Yes. All Nexus Letters are written by licensed physicians who are board-certified or board-eligible in their specialty. Our network includes doctors with extensive experience in VA disability evaluations and medical-legal opinions.
Is Claim Climbers affiliated with the VA?
No. Claim Climbers is an independent private service. We are not affiliated with, endorsed by, or connected to the Department of Veterans Affairs or any government agency.
What do I need to get started?
To start your Medical Record Review, you'll need: your VA medical records (if available), private medical records related to your condition, your DD-214 or service records, and a brief description of your claim and the condition you're claiming. We'll guide you through the process step by step.
