Major Depressive Disorder is the #2 most-claimed VA mental health condition — and the single most common secondary to PTSD. This guide covers the rating criteria, the two filing paths, the PTSD→depression secondary pathway, and what to do when the VA says no. No lawyers, no jargon, veteran-to-veteran.
Major Depressive Disorder is rated under 38 CFR 4.130 using diagnostic code 9434. The VA assesses your overall occupational and social impairment — not individual symptoms, not a checklist. A single 70% criterion met does not automatically mean 70%; the rater must assess the full functional picture. The question is what your average level of functioning looks like across work, relationships, judgment, and mood.
The rating table below uses the exact statutory language from the regulation. The C&P exam examiner uses the Mood Disorders DBQ — which maps directly to these criteria. Know the criteria before your exam.
MDD is rated under the General Rating Formula for Mental Disorders (DC 9434). The full regulation is at 38 CFR § 4.130. The VA uses the Mood Disorders DBQ at C&P exams. The table below reflects the exact statutory language — not paraphrased or simplified.
| Rating | Threshold Standard | Key Symptom Indicators |
|---|---|---|
Meeting one criterion at a higher level does not automatically produce that rating. The examiner assesses global impairment across occupational and social functioning. If your depression's actual impact on your work and relationships is not reflected in your current rating, file for a higher rating. Many MDD veterans are underrated at 30% or 50% when their symptom picture warrants 70% or higher. Full appeals guide: /appeals
The regulation states that "the rating agency shall consider the level of occupational and social impairment from all the veteran's coexisting mental disorders together with the level from service-connected physical conditions." This single sentence is the legal foundation for what's often called the PTSD-comorbidity rating boost when Major Depressive Disorder is added to an already-service-connected PTSD rating.
There are two distinct legal theories by which MDD's contribution can be captured in the rating picture, and a veteran with service-connected PTSD has both available: (1) under Amberman v. Shinseki (2012), file a separate MDD rating as secondary to PTSD — the two ratings then combine under the standard combined-ratings formula, producing a higher combined percentage than PTSD alone; (2) under the 38 CFR 4.130 rating-considerations principle, where the rater declines a separate MDD rating, the same regulation obligates them to consider MDD's contribution when evaluating the existing mental-health rating — and to elevate that rating to reflect the combined impairment picture. In practice, the second path often produces a higher effective rating than the PTSD rating alone because the rater cannot ignore the MDD impairment once it is documented. Either path captures MDD's impact, but the veteran should be prepared to invoke the rating-considerations principle explicitly if the rater tries to deny both.
Depression claims have two distinct routes to service connection. Which path fits you depends on your service history, your current service-connected conditions, and what evidence you have. Most MDD veterans have both paths available — but one is usually faster and easier.
You claim MDD as directly caused by an in-service event or condition. Requires: (1) an in-service event, injury, or stressor; (2) a current DSM-5 MDD diagnosis; and (3) a nexus linking the diagnosis to the in-service event.
Best for: Veterans whose depression began during or immediately after service, or whose depression traces to a specific in-service trauma not already claimed as PTSD.
Common in-service triggers for primary MDD: combat exposure, MST, training accidents, witnessing death, prolonged deployment stress, physical injury during service.
You claim MDD as caused or aggravated by a service-connected condition. Most common pathway: depression secondary to PTSD — the single most common secondary mental health claim.
Also secondary to: chronic pain, tinnitus, sleep apnea, TBI, back injuries, IBS. Any condition that causes chronic stress, sleep disruption, social withdrawal, or biological changes can produce MDD.
The primary condition's service connection is already established — you just need a nexus letter explaining the mechanism. This path is often faster because you don't need to prove an in-service event.
If you have service-connected PTSD, filing depression secondary to PTSD is almost always the right first move. You already have a service-connected condition, documented symptoms, treatment records, and a stressor. The primary barrier to a secondary claim is a VA rater claiming the symptoms are already captured by your PTSD rating — the Amberman case addresses this directly (see next section).
38 CFR 3.310(a): "Disabilities shall be considered to be secondary service-connected when it is established that a service-connected disability is proximately due to or the result of a service-connected disability." This covers both causation and aggravation — even if your depression would exist without the primary condition, if the primary condition worsens it, the worsening is ratable.
Major Depressive Disorder is the #1 most common secondary condition to PTSD. The biological and psychological mechanisms are well-established: chronic hyperarousal from PTSD disrupts sleep architecture, dysregulates the HPA axis, reduces neurotransmitter efficiency, and produces the social withdrawal and anhedonia that define MDD. The VA's own medical literature and VBA training materials acknowledge the PTSD→MDD nexus.
If you have service-connected PTSD, filing MDD as secondary to PTSD is the most efficient path because:
The VA's most common reason for denying a PTSD→MDD secondary claim is that the depressive symptoms are "already covered" by the PTSD rating — and therefore rating MDD separately would be pyramiding (38 CFR 4.14). Amberman v. Shinseki directly rejected this reasoning.
The Federal Circuit held that the question is not whether symptoms overlap, but whether the functional impairment attributable to MDD is distinct from the impairment already compensated by the PTSD rating. If MDD produces occupational or social impairment not adequately captured by your PTSD rating, a separate MDD rating is warranted even if the two conditions share symptoms.
This means: if your PTSD is rated at 50% and your depression causes significant additional functional impairment — major depressive episodes, anhedonia, severe occupational limitations not captured by the PTSD criteria — you are entitled to a separate MDD rating as secondary to PTSD.
A depression VA claim stands or falls on four pieces of evidence. Each one has specific requirements. Submit all of them with your initial claim — don't wait for a request.
The Mood Disorders DBQ is the structured form the VA C&P examiner uses to evaluate MDD severity. A private psychiatrist or psychologist can complete it outside the VA system and submit it with your claim. This gives the rater an independent medical opinion before the VA exam, reduces reliance on a potentially inadequate C&P exam, and documents your impairment level in your own words with a medical credential behind it. Available free at VA.gov DBQ page.
The SSRI and SNRI prescription history in your VA pharmacy records is more than a list of refills — it is a documented longitudinal record of MDD severity, chronicity, and treatment response. Three patterns matter for claims:
1. SSRI / SNRI prescriptions chronicle the severity of your MDD. Common antidepressants prescribed for veterans with MDD include citalopram (Celexa), sertraline (Zoloft), fluoxetine (Prozac), escitalopram (Lexapro), paroxetine (Paxil), venlafaxine (Effexor), duloxetine (Cymbalta), and bupropion (Wellbutrin). When the VA pharmacy record shows continuous prescriptions over months or years — multiple refills, dose escalations, augmentation with atypical antipsychotics, or switches between agents — that record constitutes chronic-disease documentation that the rater cannot dismiss. The pharmacy record proves: (1) the condition is real and requires maintenance medication, not transient distress; (2) the VA has been treating it as a diagnosed condition over time; (3) the veteran has been compliant with treatment, which strengthens the credibility of the symptom picture. Pull your VA pharmacy record through MyHealtheVet and include it with your claim — fill dates, dosage changes, and duration of each agent are all visible.
2. The SSRI / SNRI class is itself a nexus source for additional secondary claims. Long-term SSRI and SNRI use produces a number of well-documented secondary conditions that can each be filed independently: erectile dysfunction (serotonin-mediated suppression of libido and arousal — the most common and most compensable; file for Special Monthly Compensation under SMC-K), bruxism (SSRI-induced jaw-clenching and tooth-grinding, ratable as a dental / TMJ condition), gastrointestinal symptoms (nausea, IBS-pattern complaints, altered gut motility — serotonin's role in gut function), and weight changes (significant weight gain or loss documented over the prescription period). Each one of these is a separate nexus letter opportunity and a separate secondary claim. The medication list that supports your MDD claim also supports each downstream condition — make sure your treating provider documents each side-effect as it appears.
3. Treatment-resistance is one of the strongest severity signals the VA has. Treatment-resistant depression — failed first-line SSRI, dose escalation without adequate response, augmentation with an atypical antipsychotic (aripiprazole, quetiapine), switch to an SNRI, switch to bupropion, trial of an MAOI or ketamine — is direct clinical evidence that you are at the more severe end of the MDD spectrum. The 38 CFR 4.130 rating ladder treats "reduced reliability and productivity" (50%) and "deficiencies in most areas" (70%) as the next steps up from "moderate" impairment, and the most clinically defensible way to demonstrate that the veteran has crossed those thresholds is to show that standard first-line treatment did not work. A treatment record that shows two failed SSRIs followed by an SNRI trial and an atypical augmentation directly supports a 50%–70% rating — far stronger than the symptom-gradient evidence usually available.
The General Rating Formula for Mental Disorders is anchored in the language "the rating agency shall consider the level, frequency, severity, and duration of symptoms" along with "the length of time and percentage of incapacitation" required to produce the impairment picture. SSRI / SNRI pharmacy records hit every element of that test.
Frequency: daily refill cadence over years shows the disorder is not episodic. Duration: continuous prescription coverage measures chronicity in months and years. Severity: dose escalation, augmentation, and switches to higher-potency agents are direct clinical markers that first-line treatment was insufficient. Length of incapacitation: treatment-resistance extends the period of partial or total occupational and social dysfunction past the point where any reasonable clinician would expect remission. Together, these data points anchor an MDD rating at 50%–70% even when the veteran's current symptom picture, on a good day, would otherwise look like 30%.
Depression claims get denied for specific, predictable reasons. Knowing them in advance lets you build your claim to avoid them, and fight back effectively if the denial comes anyway.
This is the most common denial on PTSD→MDD secondary claims. The rater says your depressive symptoms are already compensated by your PTSD rating, so a separate MDD rating would be pyramiding.
Amberman v. Shinseki (Fed. Cir. 2012) directly addresses this. The question is not symptom overlap — it's functional impairment. Submit a private psychiatric evaluation that specifically identifies which MDD symptoms produce occupational and social impairment not captured by your PTSD rating. The evaluation should address: specific episodes of major depression beyond chronic PTSD symptoms; anhedonia distinct from hyperarousal; functional limitations in work capacity attributable to MDD specifically. A well-documented private DBQ that clearly separates MDD impairment from PTSD impairment is the strongest counter.
The VA denies primary MDD claims when they can't find a specific in-service event to connect the depression to. This is less common on secondary claims — but on primary claims, if your lay statements, buddy statements, and service records don't establish the link, the claim fails.
For primary claims: submit a detailed personal statement describing the specific in-service event or series of events that triggered the depression. Include dates, locations, unit, and immediate and ongoing effects. Submit buddy statements from fellow servicemembers who witnessed or were told about the events at the time. Service records (DD-214, deployment orders, incident reports) provide corroboration. If you already have a service-connected condition, consider pivoting to a secondary claim — the in-service event requirement for the primary is waived when you're attaching MDD to an already-service-connected condition.
The VA says your symptoms don't meet the threshold for the rating level you claimed — typically because the C&P examiner's report doesn't document sufficient impairment, or because your lay evidence was too vague.
Submit comprehensive lay statements: yours, your spouse's, a coworker's. Be specific — name the jobs you lost or quit, describe the marriages that ended, document the days you couldn't get out of bed, list the medications you're on and their side effects. Submit a private DBQ documenting the specific occupational and social impairment level. Request your C&P exam report after the exam — if the examiner made factual errors or failed to document what you described, submit a rebuttal statement before the rating decision. Get your treating VA psychiatrist's notes showing your actual functional limitations.
All three denial types are beatable. The key is submitting complete evidence with the initial claim — not waiting for the VA to ask for it. Most denials that come back with a "submit additional evidence" notice are the result of an incomplete initial submission. See: VA Claim Denied Guide → and VA Appeals Guide →
The C&P exam for MDD uses the Mood Disorders DBQ. The examiner evaluates occupational and social impairment severity and maps findings to the 0-10-30-50-70-100% criteria under 38 CFR 4.130. What you say in that room becomes the foundation of your rating. Most veterans understate their symptoms — the examiner can only rate what they document.
Minimizing symptoms. Veterans trained in toughness project competence during the exam. When asked "How are you doing?" the trained answer is "I'm managing." The honest answer — "I can't get out of bed most days, I've lost my job twice in the last year, I haven't seen my kids in months because I can't face people" — is what gets you the rating you've earned.
You are not complaining. You are accurately describing a service-connected medical condition that affects your ability to work and function. Describe your worst weeks — the major depressive episodes, the anhedonia, the days you couldn't perform basic activities. That's the truth of your MDD, and the examiner needs to hear it.
Key areas the examiner will probe — prepare honest answers for each:

You are entitled to a copy of the examination report. Request it through MyHealtheVet or by calling your regional office. If the examiner misquoted your statements, omitted key symptoms, or completed the DBQ inadequately, you can submit a rebuttal statement before the rating decision — don't wait until after the denial.
Depression causes or worsens multiple other conditions. Each successful secondary claim raises your combined VA rating and monthly compensation. These are filed as secondary to MDD (or secondary to the primary condition that caused MDD — e.g., secondary to PTSD if you're filing MDD as secondary to PTSD). Full guide: Secondary Conditions Guide →
To file secondary conditions: submit VA Form 21-526EZ listing each secondary condition with a nexus to your service-connected MDD. A nexus letter from your treating physician explaining the mechanism — how MDD caused or worsened each secondary condition — is the highest-value evidence for each claim.
If MDD (alone or combined with other conditions) prevents you from maintaining substantially gainful employment, you may qualify for Total Disability Individual Unemployability (TDIU) — which pays the 100% compensation rate regardless of your combined percentage rating. MDD at 70% with evidence of occupational impairment is often sufficient to trigger TDIU consideration. Full guide: TDIU Guide →
HadIt.com has operated since 1997 — built by veterans, for veterans, with no financial stake in your claim outcome. MDD is the #2 most-claimed mental health condition. Too many veterans with service-connected depression don't know they can file, don't know they can file secondary to PTSD, or get denied on a bad C&P exam. This guide exists to change that.
