A Summary of the 4 Requirements to a Strong Claim

Every VA mental health claim must clearly establish four things. If one is missing, the claim fails.

Requirements 1: A Current Diagnosis

You must have a current DSM-5 diagnosis from a qualified provider. Without a diagnosis, the claim does not move forward.

current diagnosis

Requirement 2: An In-Service Event or Stressor

You must show that something occurred during service that could reasonably cause your condition.

In-service event or stressor

Requirement 3: A Medical Nexus

There must be a clinical connection between your condition and your service:

“At least as likely as not” (50% or greater).

Nexus

Requirement 4: Severity and Functional Impact

You must show how your condition affects: work, relationships, and daily functioning. 

Key Point:

Most claims fail because one of these areas is: missing, weak, or poorly explained.

Understanding the steps is not enough. The next question is: How do you fully show the impact of your condition?

Severity

How to Build a Strong, Complete VA Mental Health Claim

Filing a VA mental health claim should not feel confusing, scattered, or incomplete. Yet many claims fail, not because the condition isn’t real, but because the evidence is not clearly organized, connected, or fully developed.

This page gives you a clear, simplified overview of the four critical steps required to build a strong, comprehensive claim. Each step answers a key question the VA must be able to understand and verify.

This is your starting point.

If you want to go deeper, we also provide a more detailed, step-by-step breakdown of each section, along with guidance on our website and in our podcast, so you and your support system can work through this process with clarity and confidence.

At On Point 4 Veterans, we focus on one thing: Presenting your history in a way that is complete, accurate, and taken seriously.

FOUR Requirement FOR PREPARING YOUR SUCCESSFUL CLAIM (SUMMARY) 

Requirement 1: Establish a Current Mental Health Diagnosis

You must have a current, clinically diagnosed mental health condition (PTSD, MDD, anxiety, etc.) from a qualified provider (VA or community).

  • It must meet DSM-5 criteria and be supported by symptoms and functional impact

  • A past diagnosis alone is not enough; the condition must exist now

  • The VA will not grant benefits without a clear diagnosis

  • IMPORTANT INFORMATION: YOU ARE NOT TOLD

  •  The C&P evaluator is a psychologist and, with your proper documentation, can diagnose, link/nexus, and determine the severity of your condition.

 Key question: “What condition are we evaluating?”

Why claims fail here:

  • No formal diagnosis

  • Vague or unsupported diagnosis

  • Symptoms documented, but no diagnosis assigned

Key point:
Without a diagnosis, the claim stops here.

Requirement 2: Prove an In-Service Stressor or Event

You must show that something happened during service that could reasonably cause your condition.

  • Examples: combat, MST, accidents, repeated trauma, moral injury

  • Evidence can include:

    • Service records

    • MOS exposure

    • Lay statements (you, spouse, buddies)

Standard: “More likely than not” (50% or greater)
Key question: “What happened to you?”

What matters most:

  • Clear, specific description (who, what, where, when)

  • Consistency across records

  • Patterns of exposure (not just one event)

Requirement 3: Establish the Medical Nexus (The Link)

This is the make-or-break step.

You must show it is at least as likely as not (50%+) that your condition is caused by or related to service.

  • Requires a medical opinion with clinical reasoning

  • Must connect:

    • Diagnosis

    • Service event

    • Symptom timeline

 Key question: “How do we know service caused this?”

Strong nexus includes:

  • Clear explanation (not just a conclusion)

  • Symptom onset and progression

  • Consistency with trauma type

  • Supporting lay evidence

Why claims fail here:

  • No nexus opinion

  • Weak or vague reasoning

  • Ignoring timeline or history

Requirement 4: Demonstrate Severity & Functional Impact

This determines your rating (0%–100%) under 38 CFR §4.130. The VA rates impairment, not just diagnosis. They look at:

  • Sleep, mood, anxiety, anger

  • Memory and concentration

  • Work impairment and unemployability

  • Relationships and social functioning

  • Suicidal ideation/safety concerns

 Key question: “How badly does this affect your life?”

What makes this strong:

  • Real-life examples (not just symptoms)

  • Frequency, severity, duration

  • Impact on work and relationships

 Role of the Military History Psychosocial Assessment (MH-PSA) BY ON POINT 4 VETERANS (Your Core Advantage)

Across all steps, the Military History Psychosocial Assessment (MH-PSA):

  • Organizes your full clinical story

  • Connects service → symptoms → impairment

  • Supports diagnosis, nexus, and rating

  • Reduces errors in C&P exams

 It gives the VA what they rarely have: A complete, structured picture of the veteran
