Ever submitted a VA claim only to be denied — even though you knew the condition existed?
You are not alone. Every year thousands of veterans face challenges developing strong service-connected disability evidence for the conditions that affect them the most. Mental health issues. Chronic pain. Invisible illnesses that no one can see.
Here’s the problem:
They’re some of the ailments that VA either misses, misrates or outright denies — and they impact your daily life greatly.
You’ll learn why these claims are ignored and how veterans turn their denials into approvals.

Why So Many Claims Go Unrecognised
The VA doesn’t always make life easy.
Things like mental health issues or chronic pain can be hard to prove because you may not have documentation in your service records.
Why? Many veterans suffered through these symptoms while in uniform and never reported them. Stigma. The “tough it out” mentality. Fear of what a mental health note would do to their career or reputation.
By the time you can’t ignore the symptoms… You’ve already separated, and the original event is years behind you.
That’s exactly why the proper service-connected disability evidence can be everything — and where the experts in veteran medical reviews and nexus letters come in handy. An effective nexus letter can do what your old service records cannot. It states a medical opinion from a qualified professional connecting your present condition directly to an incident that occurred while you were in service.
What do you mean without one? Denials for mental health and chronic pain claims are usually because of “no service connection.” Even if it’s painfully obvious to everyone who knows you.
The Mental Health Side Of Service-Connected Disability Proof
Mental health is one of the fastest-growing categories of VA disability claims.
And there’s a clear reason.
Veterans experience PTSD, depression, anxiety and military sexual trauma at rates exponentially higher than civilians. The problem? You can’t see mental health symptoms on an X-ray.
This is precisely the sort of claim upon which burdensome evidence must carry all the weight:
- A formal diagnosis from a qualified mental health professional
- A documented in-service stressor (combat, MST, training accident, etc.)
- A clear nexus opinion using proper “at least as likely as not” VA language
- Functional impact statements that show how daily life is affected
The totals also continue to rise. Mental health claims have gone up 10% in the past five years, partly as more veterans seek help and the stigma becomes less.
But filing isn’t the same as approval.
Claims without evidence of service-connected disabilities are denied or grossly under-rated, even if they are otherwise valid. The VA wants details — dates, diagnoses from medical professionals.
Chronic Pain — The Invisible Enemy
Now let’s talk about chronic pain.
This particular VA claim category is one of the most misinterpreted. The reason being is because the VA has no standalone diagnostic code for “chronic pain”.
That means veterans can’t simply file for “chronic pain” and expect a rating.
Instead, pain must be rated through the condition causing the pain — say a back injury, joint damage or nerve problem — or the mental health condition it causes, such as depression or somatic symptom disorder.
Here’s why this matters for your service-connected disability proof:
You need to show three things:
- The pain has a service-connected source
- The condition causing the pain is medically documented
- The functional impact on daily life is severe enough to rate
Chronic pain and mental health also overlap massively.
The VA says that 50% of veterans who have PTSD also experience chronic pain. A study released via the NIH showed that 53.2% of veterans with PTSD suffered from chronic pain as well.
That intersection is enormous — and where many secondary claims exist. Pain causing depression. Depression causing insomnia. Insomnia causing more pain.
It’s a cycle, and every part of it can potentially be service-connected.
Building Proof That The VA Actually Accepts
Ok, but how do you provide service-connected disability evidence the VA will recognize?
Here’s the process:
Get The Right Medical Documentation
You need current medical records that:
- Clearly diagnose the condition
- Describe the severity and symptoms
- Show how it limits the ability to function
Don’t make your notes generic. Include dates, how often you experience symptoms, any treatments you’ve tried, etc.
Connect It Back To Service
This is where most claims fall apart.
The nexus letter from a qualified physician is objectively the best thing you can submit. It has the proper VA-aligned language (“at least as likely as not”) and details the medical reasoning for the connection.
A strong nexus letter should include:
- Records reviewed
- A clear opinion statement
- Medical rationale linking service to current condition
- Professional letterhead and credentials
Include Lay Statements
Statements from family members, friends and fellow service members provide additional evidence. They can demonstrate how symptoms were observed by others — and how they’ve progressed.
Don’t Give Up On Denials
A denial isn’t the end of the road.
Approximately 60% of disabled veterans who are rated at 50% or higher suffer from chronic pain — so claims based on chronic pain absolutely can be approved if you have the right evidence.
You can:
- File a Higher-Level Review (no new evidence needed)
- Submit a Supplemental Claim (with new evidence like a nexus letter)
- Appeal to the Board of Veterans’ Appeals
Why are denials overturned the majority of the time? Better nexus letter that explains the service-connection gap your original claim didn’t.
The Bottom Line
Claims for mental health and chronic pain are some of the most underappreciated benefits out of the entire VA.
They are real. The injuries are real. But without proof of service-connected disability, they are denied, under-rated, or lost in years of appeals.
To quickly recap:
- Mental health and chronic pain often overlap — file secondary claims when relevant
- A strong nexus letter is the single most important piece of evidence
- Lay statements, treatment records, and functional impact notes add support
- Denials can be reversed with stronger evidence on appeal
They should be treated just like any physical injury claim. They are if you document properly.
