Use this guide to prepare and ask informed questions. VA decides claims under its rules; an accredited representative can advise you about your individual situation.
Start with care and an accurate clinical record
A mental health claim should describe the condition you experience and the evidence supporting it. A qualified clinician assesses diagnosis; a list of symptoms found online cannot establish PTSD, depression, or another disorder. Gather existing evaluations, treatment dates, and the names of providers who understand your history. If different records use different diagnoses, identify the records rather than trying to resolve the medical question yourself.
Treatment and compensation serve different purposes. You can ask about care while deciding whether to file. VA offers mental health services, including some options for people not enrolled in VA health care. For immediate crisis support, call 988 and select 1 or text 838255. Call 911 for an immediate emergency.

Separate the diagnosis from its connection to service
For PTSD, VA generally needs a qualifying diagnosis, medical evidence connecting current symptoms to an in-service stressor, and supporting evidence that the stressor occurred. Special evidence rules apply in particular circumstances, including certain combat, hostile-activity, and personal-assault claims. Deployment alone does not establish every requirement, and a person does not need combat service for every possible PTSD claim.
Other mental health conditions may involve different evidence. Organize the history into what happened during service, when difficulties appeared, and what clinicians later documented. If another service-connected disability is involved, ask an accredited representative whether a secondary claim deserves consideration. Do not assume that every mental health claim requires a traumatic event or that every diagnosis follows the same legal route.

Build a record that someone else can follow
Make a short chronology with approximate dates, duty locations, relevant treatment, and records that may help VA locate evidence. Mark an estimate as an estimate. A statement from someone who knew you can describe changes they personally observed, while a clinician addresses medical questions. A useful statement explains how the writer knows you and what they saw; it does not need to imitate a medical opinion.
VA’s current Form 21-0781 page says the form is optional. It can help identify evidence for diagnosed mental health conditions related to traumatic events. The online disability application also has optional questions covering this information. Follow specific VA correspondence if more information is requested, and seek help if an older instruction appears inconsistent.

Explain what symptoms change in ordinary life
Describe a typical period, including changes over time, rather than presenting only your best or worst day. VA’s mental-disorder evaluation rules consider symptom frequency, severity, duration, and functioning during periods of improvement. The current rating framework addresses occupational and social impairment. A diagnosis by itself does not determine the percentage.
Use concrete examples that are true for you. A hypothetical veteran might explain that interrupted sleep affects concentration at work, then describe how often this happens and what duties are affected. Another person may have a different pattern. There is no preferred story to copy. Include activities you still manage and the support that makes them possible, so the record explains both limitations and remaining abilities.

Prepare to communicate at the claim exam
A compensation and pension examination gathers evidence for a benefits decision; it is not a treatment session. Review your own timeline so you can explain it accurately. If a question is unclear, ask what the examiner means. Explain relevant changes since older evaluations, including treatment and how you function now. You do not need to memorize rating terms.
Submit new private medical records through an accepted VA channel before the appointment when possible. Handing papers to the examiner does not mean those papers have been submitted to your claim file. You may request a male or female provider for a mental health examination when scheduling. Ask about accommodations you need, and contact the scheduler promptly if you cannot attend.

Choose one manageable next step
If the evidence feels overwhelming, start with one question: what is missing from the explanation of your condition? That may be the location of an old record, a current evaluation, or a clearer description of daily limitations. An accredited representative can help distinguish a missing document from a medical question that needs professional assessment. Bring the evidence you already have rather than waiting for an ideal file.
Keep a private copy of what you submit and a list of outstanding requests. If you have a decision already, bring that letter too; the issue may be service connection, the evaluation, or both. Continue arranging the care you need while the benefits process runs. A claim decision is not a judgment about whether your distress deserves support.

Common Questions
Do I have to use VA Form 21-0781?
The current form page identifies it as optional, and the online application includes optional questions serving the same purpose. It can help VA find evidence. Respond to any specific request VA sends about your claim.
Does a PTSD diagnosis guarantee a rating?
No. VA must decide service connection and then evaluate the severity of the service-connected disability. The diagnosis, service history, medical link, and functional evidence answer different parts of that decision.
