VA Disability Nexus Letters for PTSD — Combat and Non-Combat
Dr. Jessica Allen, a psychiatrist and former VA Compensation and Pension examiner, writes physician-authored nexus letters for veterans filing PTSD claims — including combat, MST, training accidents, MVAs, disasters, and medical trauma.
This page is for U.S. veterans and service members pursuing a VA disability claim for PTSD or another trauma-related mental health condition. Brightview Psychiatry Solutions provides medical opinions only — we do not diagnose, prescribe, treat, file VA claims, or provide legal representation. If you need treatment, please contact the VA or your primary care provider.
Understanding PTSD Claims
What qualifies as PTSD for VA disability
The VA looks for a diagnosed condition tied to an in-service stressor — combat, training accidents, witnessing a death, or other traumatic events — along with current symptoms that affect your daily life and work.
If your PTSD stems from Military Sexual Trauma (MST), we have a dedicated page — including marker-evidence review and a female physician option.
You don't need to have it all figured out before reaching out. Dr. Allen reviews your records, service history, and current diagnoses and provides a clear, evidence-based medical opinion.
Common symptoms the VA recognizes
- •Nightmares, flashbacks, or intrusive memories
- •Hypervigilance or being easily startled
- •Avoidance of people, places, or activities
- •Mood changes, irritability, or feeling numb
- •Sleep disturbance and difficulty concentrating
- •Survivor's guilt or persistent negative thoughts
What Is a PTSD Nexus Letter?
A medical opinion — not a diagnosis certificate.
A PTSD nexus letter is an independent medical opinion explaining whether a veteran's current PTSD or related mental health condition is at least as likely as not connected to a traumatic event that occurred during military service. It does not simply confirm that PTSD exists. It explains how the veteran's diagnosis, symptom history, military experiences, records, and current functional impairment support the medical connection to service.
VA PTSD Ratings
How the VA rates PTSD
PTSD is rated under the General Rating Formula for Mental Disorders. The VA evaluates the level of occupational and social impairment — not the diagnosis itself.
| Rating | Criteria (summary) |
|---|---|
| 0% | Diagnosed, but symptoms do not interfere with work or social functioning; medication not required. |
| 10% | Mild symptoms that decrease work efficiency only during periods of significant stress, or symptoms controlled by continuous medication. |
| 30% | Occupational and social impairment with occasional decrease in work efficiency — depressed mood, anxiety, suspiciousness, panic attacks (weekly or less), chronic sleep impairment, mild memory loss. |
| 50% | Reduced reliability and productivity — flattened affect, circumstantial or stereotyped speech, panic attacks more than once a week, difficulty understanding complex commands, impaired judgment and abstract thinking, disturbances of motivation and mood, difficulty maintaining effective work and social relationships. |
| 70% | Deficiencies in most areas — work, school, family relations, judgment, thinking, or mood; suicidal ideation, obsessional rituals, near-continuous panic or depression, impaired impulse control, spatial disorientation, neglect of hygiene, difficulty adapting to stressful circumstances, inability to establish and maintain effective relationships. |
| 100% | Total occupational and social impairment — gross impairment in thought processes or communication, persistent delusions or hallucinations, grossly inappropriate behavior, persistent danger of hurting self or others, intermittent inability to perform activities of daily living, disorientation to time or place, memory loss for names of close relatives, own occupation, or own name. |
Summary of 38 CFR § 4.130. The VA considers the total picture, not any single symptom.
Non-Combat PTSD
PTSD can be caused by more than combat
PTSD does not require a combat stressor. Many veterans develop PTSD from non-combat experiences during service, and those claims are just as valid. Nor does a stressor require a deployment — trainees die on ranges and drop zones, and ordnance kills on flight decks.
Military sexual trauma
Special evidentiary rules under § 3.304(f)(5), marker-evidence review, and a female physician option.
Vehicle and aircraft incidents
Serious motor vehicle, aviation, and equipment accidents during service.
Witnessing a death or serious injury
You do not have to have been injured yourself for the exposure to qualify.
Disaster and humanitarian response
Hurricanes, fires, floods, and recovery operations at home and abroad.
Training and airborne operations
Range accidents, hard landings, and injuries sustained in training.
Not sure it counts?
When symptoms follow a service trauma but do not meet every PTSD criterion.
How We Help
A calm, supportive path forward
- 1
Request a Consultation
We listen first, then review your records, service history, and current diagnoses to see whether a nexus opinion is appropriate for your case.
- 2
Records Review by Dr. Allen
Dr. Allen personally reviews the records you provide — STRs, VA records, prior C&P exams, and private treatment. We do not obtain records or file claims on your behalf.
- 3
Physician-Signed Nexus Letter
You receive a psychiatrist-authored nexus letter written in the medical-legal language the VA expects — typically within 7–10 business days.
Who Can File
PTSD claim eligibility
You may be eligible if any of the following apply to you.
Combat veterans of any era
Veterans exposed to traumatic events during service or training
Veterans whose symptoms appeared years after separation
Beyond that, the stressor rules, the records that exist, and the arguments that work all depend on where you served and what you did there. A convoy gunner and a mortuary affairs specialist both have valid claims, and almost nothing about how they are documented is the same.
Find your MOS, deployment, or type of event — stressor patterns and evidence by role, from Coast Guard and military police to mortuary affairs, medics, submarine service, and combat deployments.
Not sure whether your service qualifies?
Dr. Allen reviews your records and service history and tells you directly whether a medical opinion would strengthen your claim — including when it would not.

Once PTSD Is Granted
What else can I claim?
Service connection for PTSD is often the beginning rather than the end. A rated psychiatric condition can cause or aggravate physical conditions, and so can the medication treating it — each evaluated under its own criteria, with no ceiling set by the PTSD rating. These are the pathways Dr. Allen documents most often.
Sleep
Sleep Apnea Secondary to PTSD
Sleep fragmentation, nocturnal hyperarousal, and treatment-related weight change.
Neurological
Headaches and Migraine
Central sensitization and disrupted sleep as an established trigger.
Genitourinary
Urinary Frequency
Mental health conditions can cause frequent urination.
Cardiovascular
Hypertension
Sustained sympathetic activation and disrupted neuroendocrine regulation.
Digestive
GERD and Digestive Conditions
Gut-brain axis disruption and altered autonomic regulation.
Genitourinary
Erectile Dysfunction
Autonomic effects and psychotropic medication, with SMC-K where it applies.
Medication
Hemorrhoids from Psychiatric Medication
Reduced gut motility, chronic straining, and the pathway almost nobody files.
Medication
Diabetes from Antipsychotic Medication
An FDA class warning, and a claim with a long tail of rated complications.
