Introduction

Filing for VA disability compensation is one of the most important actions a veteran can take after service. But while the VA system is designed to support you, it’s not forgiving when mistakes are made. From missing medical appointments to filing with incomplete evidence, even simple errors can delay your claim—or cost you the benefits you’ve earned.

In this guide, we’ll walk through the most common VA claim mistakes that can derail your case and show you exactly how to avoid them. Whether you’re filing your first claim or appealing a decision, these insights can save you time, money, and frustration.


Mistake #1: Failing to Submit Medical Evidence

The VA won’t take your word for it—you need proof. One of the top reasons claims are delayed or denied is because the veteran failed to submit sufficient medical documentation showing they:

  • Have a current, diagnosed condition

  • Experienced relevant symptoms or treatment during service

  • Can link the condition to service (directly or secondarily)

Too many veterans simply list a condition on the application but provide no supporting records, leaving the VA to guess or reject the claim due to “lack of evidence.”

How to avoid it:
Gather and submit military treatment records, VA clinic records, and private provider documentation with your initial claim. If your condition is not well-documented in service, provide lay statements or a nexus letter from a doctor explaining the connection.


Mistake #2: Missing or Ignoring a C&P Exam

The Compensation and Pension (C&P) exam is one of the most critical parts of your claim. It’s where the VA evaluates the severity of your condition and, in many cases, decides whether it’s connected to your service.

Missing your C&P appointment—even for understandable reasons—can result in the VA denying your claim outrightfor failure to cooperate.

How to avoid it:
Always attend your scheduled exam. If you have a conflict, reschedule immediately through the contractor (e.g., QTC, VES, or LHI). After the exam, request a copy of the examiner’s notes—they could help or hurt your claim depending on what was recorded.


Mistake #3: Not Explaining How Conditions Are Service-Connected

The VA requires more than just listing a disability—they want to know how it’s related to your service.

Many veterans skip the explanation, especially with secondary conditions like sleep apnea (from PTSD) or joint pain (from an altered gait due to a leg injury). Without a clear connection, the VA can’t legally approve your claim.

How to avoid it:
Include a narrative in your claim explaining how your condition is related to service. If it’s secondary, clearly state the primary condition it’s connected to. Consider including a medical opinion (nexus letter) stating it’s “at least as likely as not” caused or aggravated by service.


Mistake #4: Filing Too Late or Not Preserving Your Intent

There’s no deadline for filing a VA claim—but the date you file determines when your compensation begins. Veterans who wait months or years lose out on thousands of dollars in back pay.

Even worse, if you miss an appeal deadline, your only option may be starting over from scratch.

How to avoid it:
Submit an Intent to File through VA.gov. This gives you up to 12 months to gather evidence while protecting your effective date. Also, be aware of the 1-year window to appeal decisions.


Mistake #5: Submitting Incomplete Claims

It’s tempting to rush through the VA.gov forms just to “get it over with.” But that’s where mistakes happen. If you forget to list a condition, fail to upload records, or leave fields blank, your claim may be processed without critical information—or delayed while the VA requests clarification.

How to avoid it:
Slow down. Review your submission carefully. Use the Fully Developed Claim (FDC) program if possible—but only if you have everything ready. And always keep copies of everything you submit.


Mistake #6: Refiling Instead of Appealing

Many veterans are denied benefits and think they must start over by filing a new claim. That’s not always necessary—and it can hurt your chances if you don’t address the issues from your denial.

How to avoid it:
Use the appeals options: Higher-Level Review, Supplemental Claim, or a Board Appeal. Each one is designed for different circumstances and can preserve your original effective date (which means more back pay if approved).


Mistake #7: Trying to Navigate Alone Without Help

The VA system is complex. Rules change. New forms are introduced. And the VA won’t always explain why your claim is stuck. Many veterans make avoidable errors simply because they didn’t know better.

How to avoid it:
Get support from a Veteran Service Officer (VSO) or accredited claims agent. These professionals don’t charge for their help and can catch errors, submit stronger evidence, and guide you through appeals.


Bonus Mistake: Assuming Your Rating Is Permanent

Just because you’ve been granted benefits doesn’t mean they’ll last forever. If your rating is marked “not static,” the VA may schedule future exams to reevaluate your condition.

How to avoid it:
Understand whether your rating is protected or subject to review. Continue medical treatment. And always respond to VA exam requests—even years after approval—to avoid having your rating reduced or terminated.


Final Thoughts

Mistakes happen—but in the world of VA claims, they can cost you years of benefits and delay the care you need. The system isn’t perfect, but it does reward preparation, persistence, and attention to detail.

By avoiding these common pitfalls and using the resources available to you, you dramatically increase your chances of getting approved—and getting the full compensation you deserve.
