VA Depression Claims: Service Connection, Ratings, and Evidence
Plain-English guide to filing a VA depression claim — service connection paths, rating criteria, and how depression often shows up secondary to other conditions.
Major Depressive Disorder is rated under VA diagnostic code 9434 using the General Rating Formula for Mental Disorders. Veterans can establish service connection directly, presumptively, or as secondary to a service-connected physical condition like chronic pain or tinnitus.
Depression doesn't always start with a single event. For many veterans it builds slowly — from chronic pain, sleep loss, or the loss of identity that comes after separation.
The VA recognizes all of those paths. The question is how clearly you document them.
Three Paths to Service Connection
Direct
Depression that started during service and is documented in service treatment records.
Secondary
Depression caused or worsened by a service-connected condition — chronic back pain, tinnitus, TBI, and amputations are common triggers.
Aggravation
A pre-existing depression that got worse during service beyond its natural progression.
Evidence That Builds a Strong Claim
- Continuity of treatment — even brief therapy episodes documented over time
- A complete medication history showing what's been tried and adjusted
- Lay statements about mood changes, isolation, or loss of interest observed by others
- A nexus letter explaining the specific medical link to service or to a service-connected condition

Veterans with severe service-connected pain, tinnitus, sleep apnea, or PTSD are at meaningfully elevated risk for depression. The medical literature broadly supports this link, and a well-written nexus letter explaining the specific mechanism — chronic pain's effect on mood regulation, for example — often carries the entire secondary claim on its own.
Why Documenting the Decline Over Time Matters
Depression that builds gradually can be harder to pin down evidentially than an acute onset condition, which is exactly why continuity of documentation matters so much. A treatment history showing a clear trajectory — first noticing symptoms, seeking help, adjusting treatment — tells a more persuasive story to a rater than a single recent diagnosis with no supporting history.
Common mistakes to avoid
- Claiming 'depression' without a formal diagnosis.
- Missing the secondary connection — most denials happen when veterans only file directly.
- Stopping treatment because it 'isn't helping' without documenting why.

Conclusion
If service-connected pain or trauma has slowly drained your motivation, that's a recognizable, ratable pattern. Get the diagnosis, document the link, and file. Educational only. Not legal advice.
