Understanding Depression / Major Depressive Disorder VA Disability
Depression and Major Depressive Disorder (MDD) are among the most prevalent VA-rated mental health conditions. The VA rates depression under the General Rating Formula for Mental Disorders at 38 CFR § 4.130, Diagnostic Code 9434, using the same 0–100% scale as PTSD and other psychiatric conditions.
VA Rating Schedule for Depression / Major Depressive Disorder
The VA rates depression / major depressive disorder under the VA Schedule for Rating Disabilities (38 CFR). The following table shows each possible rating level and what it represents clinically. Your rating is based on the severity of symptoms documented during a Compensation and Pension (C&P) examination and supported by your medical records.
| Rating | Clinical Criteria & Functional Impairment |
|---|---|
| 0% | Diagnosis exists but symptoms are not severe enough to interfere with occupational and social functioning, or symptoms are controlled by continuous medication. |
| 10% | Mild or transient symptoms that decrease work efficiency during periods of significant stress; controlled by medication. |
| 30% | Occasional decrease in work efficiency and intermittent inability to perform occupational tasks, though generally functioning satisfactorily. |
| 50% | Reduced reliability and productivity; flattened affect, panic attacks, memory impairment, mood disturbances, difficulty maintaining effective work relationships. |
| 70% | Deficiencies in most areas including work, family relations, and mood; suicidal ideation, persistent depression, near-continuous panic, inability to function independently. |
| 100% | Total occupational and social impairment; gross impairment in thought or communication, danger to self or others, persistent hallucinations or delusions. |
How a Nexus Letter Helps Your Depression / Major Depressive Disorder VA Claim
A nexus letter is a medical opinion, written and signed by a licensed physician, that establishes the connection between a veteran's current diagnosis and their military service. The VA requires this "nexus" as one of three elements for service connection under 38 CFR § 3.303: a current diagnosis, an in-service event or injury, and a medical link between the two.
A nexus letter for depression must establish either direct service connection (depression arose during or was caused by military service) or secondary service connection (depression was caused or aggravated by a service-connected condition such as PTSD, chronic pain, TBI, or physical disability). The physician should document: the current MDD diagnosis with DSM-5 criteria, the temporal relationship between military service or the primary service-connected condition and depression onset, how the veteran's service experience contributed to depression, and medical literature supporting the connection. Secondary depression linked to chronic pain is especially well-documented in the peer-reviewed literature and is highly amenable to nexus documentation.
Semper Solutus provides MD-authored nexus letters written by physicians experienced in VA rating criteria and 38 CFR standards. Our letters use the "at least as likely as not" language required by VA adjudication standards and include a thorough review of all available medical records.
Secondary Conditions Commonly Linked to Depression / Major Depressive Disorder
When a condition is caused or aggravated by a service-connected disability, it may qualify for secondary service connection under 38 CFR § 3.310. This means veterans with service-connected depression / major depressive disorder may be able to claim additional compensation for related conditions. The following conditions are frequently documented as secondary to depression / major depressive disorder:
PTSD
Depression most commonly develops as a secondary condition to service-connected PTSD.
Anxiety Disorder
Comorbid anxiety and depression are frequently evaluated together.
Lower Back Pain
Chronic pain from musculoskeletal injuries is a well-established cause of secondary depression.
Traumatic Brain Injury (TBI)
Depression is one of the most common sequelae following TBI in veterans.
Medical Evidence That Strengthens a Depression / Major Depressive Disorder VA Claim
Key evidence: a current diagnosis from a licensed psychiatrist, psychologist, or primary care provider; treatment records documenting the course of depressive symptoms; service records documenting traumatic events or service stressors; if secondary, records establishing the primary service-connected condition and medical literature linking it to depression; personal statements describing functional limitations; and buddy letters from family or employers documenting behavioral changes.
Frequently Asked Questions: Depression / Major Depressive Disorder VA Disability
Yes. Depression can be service-connected based on any military stressor, including MST, loss of fellow service members, the stress of military culture itself, or as a secondary condition to a physical disability caused by service.
Generally, the VA evaluates all mental health conditions together under a single rating when they share a common etiology under 38 CFR § 4.126(a), rather than assigning separate ratings for PTSD and depression.
Yes. If depression is well-controlled by medication with no occupational or social impairment, the VA may assign a 0% rating. However, if medication has side effects that impair functioning, those side effects may influence the overall rating.
Direct service connection means the depression was caused by an in-service event. Secondary service connection means depression was caused or aggravated by an already service-connected disability. Both pathways require a nexus letter connecting the condition to service or to the primary service-connected disability.
