VA Disability for Depression and Anxiety
Depression and anxiety may qualify for VA disability compensation when the requirements for service connection are met: a current diagnosis, a qualifying connection to military service or to another service-connected condition, and medical evidence supporting that link. VA doesn’t rate the diagnosis itself — it rates how much the condition affects your ability to work and maintain relationships. Where the connection to service isn’t clear from your records, a medical nexus opinion may help establish it.
Can Depression and Anxiety Qualify for VA Disability?
Yes. Mental health conditions are among the most commonly service-connected disabilities, and depression and anxiety disorders are evaluated the same way as any other condition VA compensates.
Three things have to line up. You need a current diagnosis from a qualified mental health professional, made according to DSM-5 criteria — VA requires this under 38 CFR § 4.125. You need a qualifying in-service event, injury, illness, or stressor, or an already service-connected condition that caused or worsened the mental health condition. And you need a medical link between them.
The second and third elements are where most claims run into difficulty. Many veterans never sought mental health care in uniform. Seeking help carried professional consequences, and plenty of people simply pushed through. Years later the service records are silent, and VA reads that silence as evidence the condition began after discharge.
That silence isn’t disqualifying. Your own account of what you experienced is competent evidence, and statements from people who knew you then and now can document changes the records never captured.
How Does the VA Rate Depression and Anxiety?
VA rates mental health conditions under 38 CFR § 4.130, using the General Rating Formula for Mental Disorders. Ratings are assigned at 0, 10, 30, 50, 70, and 100 percent.
What determines the level is occupational and social impairment — how much the condition interferes with working and with relationships. The levels describe:
- 0% — a diagnosis exists, but symptoms aren’t severe enough to interfere with functioning or require continuous medication
- 10% — mild or transient symptoms that decrease work efficiency only during periods of significant stress, or symptoms controlled by continuous medication
- 30% — occasional decrease in work efficiency, with intermittent periods of inability to perform occupational tasks
- 50% — reduced reliability and productivity
- 70% — deficiencies in most areas: work, school, family relations, judgment, thinking, or mood
- 100% — total occupational and social impairment
The regulation lists example symptoms at each level, but courts have made clear those lists are illustrative rather than a checklist. You don’t need to exhibit every listed symptom, or even most of them, to warrant a given rating. What matters is whether your overall level of impairment matches — though symptoms do have to occur with comparable frequency, severity, and duration.
No single symptom automatically produces a particular rating. VA is directed to assign an evaluation based on all the evidence bearing on occupational and social impairment, not solely on how you presented during one examination.
VA has proposed replacing this formula with a system based on five domains of functioning. As of this writing that proposal has not been finalized, and the current criteria still govern.
What Symptoms Can Affect a VA Mental Health Rating?
The symptoms that bear on a rating include depressed mood, anxiety, chronic sleep impairment, panic attacks, difficulty concentrating, memory problems, irritability, reduced motivation, social withdrawal, difficulty establishing and maintaining relationships, difficulty adapting to stressful circumstances, and impaired judgment or thinking.
You do not need to experience all of these. What tends to matter more than the symptom list is documentation of effect — the shifts you’ve dropped, the relationships that ended, the tasks you can no longer complete reliably. Records describing function tend to carry more weight than records noting only that symptoms exist.
Depression vs. Anxiety in a VA Disability Claim
These are distinct diagnoses that frequently co-occur, and their symptoms overlap considerably. Major depressive disorder falls under Diagnostic Code 9434; generalized anxiety disorder under 9400.
Here’s the part veterans often misunderstand: carrying two mental health diagnoses does not produce two ratings. Under VA’s rule against pyramiding at 38 CFR § 4.14, all service-connected mental health conditions are evaluated together under a single rating using the same general formula, because the same symptoms can’t be compensated twice.
That isn’t as unfavorable as it sounds. The single rating accounts for your total symptom burden, and comorbid conditions often produce greater combined impairment than either alone. It also means precise diagnostic labels matter less than you might expect — a claim for one mental health condition is generally understood to encompass the psychiatric diagnoses reasonably raised by the record.
What Evidence Supports a Depression or Anxiety VA Claim?
Requirements vary by claim, and no veteran needs everything here.
A current diagnosis is the foundation. Beyond that: VA and private mental health treatment records, therapy notes, psychiatric evaluations, medication history including changes and dosage adjustments, and service treatment records where any complaint exists. Service personnel records sometimes help too — a sudden drop in evaluations or unexplained disciplinary issues can corroborate onset.
Statements from a spouse, family member, or coworker describing what they’ve observed are frequently the most useful evidence in the file, because they document impairment in a way clinical notes rarely do.
Then C&P examination findings, a completed mental health DBQ, and — where the connection to service is contested — a medical nexus opinion.
What Is a Nexus Letter for Depression and Anxiety?
A nexus letter is a written medical opinion addressing whether your current mental health condition is connected to your military service, to a specific in-service event or injury, or to another service-connected condition.
It’s expressed using VA’s evidentiary standard: at least as likely as not, meaning a probability of 50 percent or greater. It is a medical opinion offered as evidence — not a decision, and not a guarantee of approval. VA weighs it alongside everything else in the file.
When Can a Nexus Letter Help With a Depression or Anxiety Claim?
Not every claim needs one. If your records document in-service mental health treatment and your current diagnosis follows from it, VA may establish the connection without additional evidence.
A nexus opinion tends to matter when the connection is medically complex, when service records don’t clearly establish it, when a C&P examiner reached an unfavorable conclusion, when you’re claiming a mental health condition secondary to something already rated, or when aggravation needs to be addressed and nothing in the file speaks to it.
Depression and Anxiety Secondary to Another Service-Connected Condition
Under 38 CFR § 3.310, a mental health condition may be service-connected where competent medical evidence shows it was caused or aggravated by an already service-connected condition.
This is one of the more commonly granted secondary theories. Veterans living with chronic pain, lost mobility, disfigurement, or a serious illness frequently develop depression or anxiety as a consequence, and the Board has granted such claims where a clinician explained the relationship on the individual facts of the case.
Causation means the service-connected condition produced the mental health condition. Aggravation means it worsened one that already existed beyond its natural progression — a separate theory that requires evidence of the baseline severity beforehand, and that compensates only the increase above that baseline.
Whether either applies to you depends on your diagnosis, your history, and your records. That two conditions exist together establishes nothing on its own.
What Should a Depression or Anxiety Nexus Letter Include?
A useful opinion reads as clinical reasoning about one person, not a template with a name inserted.
It should identify the records reviewed and state the current diagnosis. It should cover the relevant history — service history, symptom onset and progression, treatment attempted and how you responded. It should address alternative explanations honestly, including non-service stressors, rather than pretending they don’t exist. It should reference medical literature where the literature genuinely applies. And it should reach a clear conclusion with the reasoning that supports it.
Where secondary service connection is at issue, it should address causation and aggravation both.
Why Medical Rationale Matters
“The veteran’s depression is related to service” is a conclusion, not evidence.
Board decisions have found even favorable private opinions inadequate when they stated a conclusion without explaining it. What persuades is the reasoning that connects the record to the conclusion — why this symptom timeline fits this history, why the competing explanation is less likely. That’s the difference between an opinion that gets weighed and one that gets set aside.
What If Your VA Depression or Anxiety Claim Was Denied?
Read the decision closely before reacting to it.
Identify the favorable findings — VA is generally bound by them, and they may already establish part of your claim. Then find the stated reason for denial and determine which element failed. Was there no nexus evidence at all? Did the examiner acknowledge the diagnosis but attribute it to something outside service? Did the decision turn on severity rather than service connection? Each points somewhere different.
Check what evidence VA actually considered. Records you assumed were in the file sometimes aren’t.
Where the gap is medical, additional medical evidence may address it. Where the issue is procedural, consider working with a VA-accredited attorney, claims agent, or Veterans Service Organization. This page is general information, not individualized medical or legal advice.

Frequently Asked Questions
Can depression qualify for VA disability?
Yes, when service connection is established — a current DSM-5 diagnosis, a qualifying link to service or to a service-connected condition, and medical evidence connecting them.
How does the VA rate depression and anxiety?
Under 38 CFR § 4.130 at 0, 10, 30, 50, 70, or 100 percent, based on how much your symptoms impair occupational and social functioning rather than on the diagnosis itself.
Do I need a nexus letter for a VA depression claim?
Not always. A medical nexus opinion helps most when the connection to service isn’t clear from your records, after an unfavorable C&P opinion, or on a secondary claim.
Can anxiety or depression be secondary to another service-connected condition?
Yes. Under 38 CFR § 3.310, they may be service-connected if caused or aggravated by a rated condition — commonly chronic pain — with competent medical evidence supporting the link.
What should a depression or anxiety nexus letter include?
A review of your records, current diagnosis, symptom and treatment history, honest treatment of alternative causes, and a clear medical conclusion with the rationale behind it.
Nexus Veteran MD provides physician-written medical nexus opinions and DBQs for veterans and for the law firms representing them.
For a depression or anxiety claim, that means individualized review of your treatment history, medication records, service records, and any prior C&P findings — then an honest assessment of whether the evidence supports a favorable opinion, and on which theory. Where it does, the opinion explains the medical reasoning, addresses causation and aggravation where secondary service connection is at issue, and engages the alternative explanations an adjudicator will raise.
Where the evidence doesn’t support a favorable opinion, we say so. That’s what makes the opinions worth submitting.
