Mental health claims are decided on evidence, and the evidence that matters is more specific than most veterans expect. This guide walks through what strengthens a file, what weakens it, and where an independent evaluation fits. For the regulatory framework behind it all, start with our PTSD service connection overview.
1. A current diagnosis that meets recognized criteria
Under 38 CFR 4.125(a), a mental disorder diagnosis must conform to the criteria the VA recognizes. A diagnosis noted in passing carries less weight than one made by a qualified clinician who documents which criteria are met and on what basis.
2. Evidence of the in-service event or stressor
For PTSD, this is 38 CFR 3.304(f) territory - combat and fear-based stressors are treated differently from others, and personal assault claims have their own provisions. Our stressor evidence guide covers each route. For depression and anxiety, the equivalent is in-service documentation or a service-connected disability the condition can be tied to secondarily.
3. Treatment records over time
Consistency is what makes a record persuasive. Notes across years showing symptom frequency, medication changes, therapy attendance, hospitalization, and response to treatment describe a trajectory. Gaps are not fatal, but they should be explainable - and avoidance of care is itself a documented feature of some conditions.
4. Functional and occupational evidence
Because 38 CFR 4.130 measures occupational and social impairment, evidence about functioning does more work than symptom labels:
- Work history - absences, performance reviews, discipline, job changes, periods of unemployment
- Education records where schooling was affected
- Daily functioning - sleep, concentration, self-care, driving, leaving the house
- Relationships - isolation, conflict, loss of contact with family or friends
Where veterans start
Every case is different, and there is no obligation at any step. When veterans want to understand what their records actually support, these are the two most common starting points:
- Medical records review
A licensed physician reviews your records for a $250 flat fee and identifies which conditions the available evidence may support. The fee is refunded in full if nothing supportable is identified.
- Individual Psychological Evaluation Package
A telehealth evaluation with a psychologist licensed in your state. It includes a one-on-one evaluation of your history, symptoms, and functional impact, a DBQ when clinically appropriate, and a nexus opinion section when the evaluation supports one. It starts with a free screening - you pay nothing unless a full evaluation appears clinically appropriate.
5. Lay statements from people who see it
Statements from a spouse, adult child, coworker, supervisor, or fellow service member are competent evidence of what the writer has personally observed. The useful ones are concrete and dated: what changed, when it started, and what it looks like week to week. Vague praise or generalities add nothing.
6. A reasoned medical opinion
Where the link between the condition and service is the contested point, a written opinion can address it. A probative opinion identifies the evidence reviewed, states the diagnosis and criteria met, applies recognized medical reasoning to this specific record, addresses competing explanations, and states its conclusion in the VA's own terms - see our guide to at least as likely as not.
The six weaknesses that most often undermine a file
In practice, the same problems appear again and again:
- A diagnosis without documented criteria or clinical basis
- An unsupported stressor where the regulation requires corroboration
- A treatment record too thin to show severity over time
- Evidence describing symptoms but never functioning
- An opinion that asserts a conclusion without reasoning
- An opinion that ignores an obvious alternative explanation
Where to start
The first step is knowing what your file already shows. A paid medical records review is $250 and tells you whether the available evidence supports a medically defensible opinion before anything further is ordered. Where a current clinical evaluation is the missing piece, our Individual Psychological Evaluation Package pairs you with a psychologist licensed in your state and begins with a free screening.
Talking through your situation by phone is always free, and there is never any obligation. Patriot NEXUS Letters provides independent medical evidence, not legal representation or claim filing. We do not guarantee that a medical professional will reach a favorable conclusion or that the VA will approve any claim.
