Increase Your VA Disability Rating
When your symptoms worsen or a secondary condition like sleep apnea develops, stronger medical evidence can help support a higher VA rating. Claim Climbers reviews your service and medical records to identify whether there is a supportable path forward and, when appropriate, provides detailed Nexus Letters to help strengthen your claim.

Why VA Ratings Fall Short
The VA may deny or underrate your claim when symptoms have worsened, functional impact isn't documented, or secondary conditions like sleep apnea aren't clearly connected.
Symptoms Worsened
Your condition has progressed, but current records don't reflect the increased severity.
Functional Impact
How your condition affects work, sleep, or daily life isn't clearly documented.
Secondary Connection
Conditions like sleep apnea may be linked to service, but insufficient medical evidence explains the connection.
Missing Medical Language
VA-appropriate medical terminology and rationale are absent from your records.

Sleep Apnea Nexus Letters for Secondary VA Claims
Understanding the connection may open a path to additional compensation
What Does "Secondary Condition" Mean?
In some cases, sleep apnea may be secondary to another service-connected condition. This means sleep apnea wasn't directly caused by military service — but it was caused or worsened by a condition that was.
PTSD Connection
Sleep apnea secondary to PTSD due to anxiety, hypervigilance, or nightmares disrupting sleep patterns.
Rhinitis/Sinusitis
Sleep apnea secondary to chronic nasal obstruction from service-connected rhinitis or sinusitis.
Tinnitus
When stress, anxiety, or insomnia caused by ringing in the ears triggers or exacerbates breathing issues or chronic sleep deprivation weakens physical health.
What This Means for Your Claim
If the VA can see a clear medical explanation for how one service-connected condition led to or worsened sleep apnea, you may qualify for separate compensation for sleep apnea as a secondary condition. The key is strong medical evidence that explains the connection in terms the VA understands. A well-supported Nexus Letter can provide that clarity.

Why Medical Evidence Drives VA Rating Decisions
When medical records don't clearly explain how a condition has worsened, how it limits function, or how sleep apnea is connected to service, the VA may underrate a claim — or deny it entirely.
Strong medical evidence helps the VA understand:
Progression
How your condition has changed since your original rating.
Severity
The current intensity of symptoms and clinical findings.
Functional Impact
How the condition affects your ability to work, sleep, perform daily tasks, or maintain relationships.
Secondary Connection Rationale
The medical pathway linking sleep apnea (or another condition) to an existing service-connected issue.
A comprehensive Nexus Letter provides this evidence in a format the VA is built to evaluate. It doesn't guarantee approval — but it ensures the medical rationale is clear, defensible, and aligned with VA standards.

Veterans Who Increased Their Ratings
"I used Claim Climbers for a Nexus letter which I included in my VA claim. My claim was accepted and my % was increased. Communication from start to finish was great. I was able to add a secondary service connection from an existing one. I included their Nexus letter along with a VA Dr visit, several non-VA Dr visits, an urgent care visit, and several buddy letters. Claim Climbers Nexus letter gave me the confidence and document I needed to achieve the result I hoped for."
"Was a fantastic experience. Every team member was attentive, professional and highly communicative. I had two NEXUS letters completed with excellent results. My rating was increased from 70% to 90%. Total time from letters to decision was 4 months. I highly recommend Claim Climbers. No hard sell, no ridiculous costs. Completely transparent pricing for exactly what they promised."
"Claim Climbers has done an excellent job with my Military Service Connection Claim. After a denial on a few of my claims I began to search for a company to fill out a Nexus Letter to connect my claims to Service related / Secondary related Claims. [...] I found it hard to get the final 10% to receive 100% Military Disability. Claim Climbers was the very thing I needed at a reasonable price. They were quick and detailed on explaining, in legal terms, my case for Veterans Claims. Still awaiting for a final decision on my Claim for Sleep Apnea Appeal. I highly recommend Claim Climbers, you will definitely need this Nexus Letter get your service connected Claim finalized."
Frequently Asked Questions
What you need to know about VA rating increases and Secondary Condition claims
Can sleep apnea be a secondary condition for VA disability?
Yes. Sleep apnea can be secondary to service-connected conditions like PTSD, rhinitis, sinusitis, or weight gain caused by service-connected issues or medications. The VA may grant separate compensation if there's clear medical evidence showing the connection.
Can I seek a rating increase if I already have a VA rating?
Yes. If your condition has worsened since your original rating, or if new secondary conditions have developed, you may file for an increase. Strong medical evidence that explains the progression, severity, and functional impact is critical to supporting your claim.
What if I'm not sure whether sleep apnea is connected to another condition?
That's exactly what we help determine. During the record review, we assess whether there's a supportable medical connection. If there is, we can help you obtain the evidence needed to pursue a secondary service connection claim.
What if I don't have all my records yet?
That's okay. We can guide you on how to request service records, VA medical records, and private treatment records. In some cases, we can proceed with what's available and identify gaps along the way.
What does a Nexus Letter help explain?
A Nexus Letter is a medical opinion that connects the dots between your service, your current condition, and VA rating criteria. It explains progression (how your condition has worsened), severity (current symptoms and findings), functional impact (how it limits your life), and secondary connection (if applicable, how one condition caused or worsened another).
How long does the process take?
Most eligibility reviews are completed within 48 hours. Once matched with a physician, Nexus Letters are typically delivered within 7-10 business days. We prioritize speed without sacrificing quality.
Is a rating increase guaranteed?
No. No service can guarantee VA approval or a specific rating. A Nexus Letter provides strong medical evidence, but the VA makes the final decision. Our goal is to give you the best possible medical documentation to support your claim.
How much does a Nexus Letter cost?
How much does a Nexus Letter cost?Nexus Letters start at $795, with quantity discounts available if you need more than one. Medical Record Reviews are $195. 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.
Does the provider need to be in my state?
No. VA Nexus Letters are medical opinions, not treatment records, so the physician does not need to be licensed in your state. Our physicians are licensed and qualified to provide expert medical opinions for VA disability claims nationwide.
What do I need to get started?
To check your eligibility, you'll need: your current VA rating decision or award letter, VA and private medical records related to your condition(s), your DD-214 or service records, and a brief description of what you're seeking to increase. We'll guide you through the process step by step.
