How to Claim Depression as a Secondary VA Disability (Updated September 3, 2026)
Veterans can receive VA compensation for depression after service by showing how their depression was caused or (if preexisting) aggravated by another service-connected illness or injury. For example:
- A veteran has a service-connected condition (such as cancer); and
- The veteran is diagnosed with depression; and
- A medical professional writes a letter (a “nexus opinion”) finding that the first condition “at least as likely as not” caused or aggravated the depression
According to VA’s FY2025 Annual Benefits Report, major depressive disorder is the second-most prevalent mental health condition, with over 400,000 veterans receiving VA compensation for it, either as a primary or secondary condition. As a VA-accredited law firm that has represented over 36,000 clients fighting VA decisions — many of whom have come to us after years of battling for compensation — we have clearly seen that years of service-connected symptoms like chronic pain or reduced mobility can have a detrimental effect on mental health.
This guide is based on our experience building these cases.
Key points covered in this article:
- Non-obvious primary conditions, such as migraines, sleep apnea, tinnitus, and traumatic brain injury (TBI), still frequently lead to depression.
- Secondary service connection requires a current depression diagnosis, an already service-connected primary condition, and a nexus opinion linking the two.
- The VA rating for secondary depression ranges from 0 to 100 percent under the same General Rating Formula for Mental Disorders used for every other mental health condition. In most cases, all mental health conditions (depression, anxiety, PTSD, etc.) are combined into one rating. Then the mental health rating is combined with the veteran’s other ratings (e.g., their first condition) using a formula called “VA math.”

What VA Ratings Can I Get for Depression as a Secondary Condition?
Just like for depression directly caused by service, veterans suffering from depression as a secondary VA disability can earn ratings of 0, 10, 30, 50, 70, or 100 percent. Depression is rated using the General Rating Formula for Mental Disorders under 38 CFR § 4.130 (Diagnostic Code 9434), which is also used to rate other mental health conditions like PTSD and anxiety.
The chart below summarizes the possible percentage ratings a veteran can earn for depression as a secondary VA disability:
| VA rating | General criteria for rating depression (and other mental health conditions) |
| 100 percent | Total occupational and social impairment (for example, persistent danger of hurting self or others, disorientation to time or place, or gross impairment in communication). |
| 70 percent | Occupational and social impairment with deficiencies in most areas, such as work, family relations, or judgment (for example, suicidal ideation, near-continuous panic, or an inability to maintain relationships). |
| 50 percent | Occupational and social impairment with reduced reliability and productivity (for example, panic attacks more than once a week, impaired judgment, or disturbances of motivation and mood). |
| 30 percent | Occupational and social impairment with occasional decrease in work efficiency (for example, depressed mood, chronic sleep impairment, or weekly panic attacks). |
| 10 percent | Mild or transient symptoms that decrease work efficiency only during periods of significant stress, or symptoms controlled by continuous medication. |
| 0 percent | A diagnosis of depression exists, but symptoms are not severe enough to affect occupational or social functioning. |
Importantly, in the case Mauerhan v. Principi, 16 Vet. App. 436 (2002), the Court of Appeals for Veterans Claims (CAVC) held that the symptoms listed in the General Rating Formula for Mental Disorders are examples, not a required checklist. Essentially, this means a veteran’s overall level of occupational and social impairment, not an exact symptom match, determines the correct VA rating.
Warning: Already Have a Mental Health VA Rating? You Can Only Have One (But Can Increase the First)
If you already have a mental health rating (e.g., anxiety or PTSD), you will likely not be able to get a new rating for depression. All mental health symptoms are given a single rating. That said, if you develop new symptoms due to depression, you may be able to file an increased-rating claim and get a higher rating for your mental health condition.
Note that some conditions that resemble mental health conditions may receive their own ratings. Common examples include migraines or TBI. VA often makes mistakes assigning ratings in situations like this. If you disagree with a VA decision, contact CCK Law.
Remember: Additional Ratings Use “VA Math” (They Do Not Increase Your Combined Rating As Much
When VA grants a new rating via secondary service connection, it calculates the veteran’s new combined rating using a formula called VA math. For example, a 50 percent rating for migraines and a 30 percent rating for depression will lead to a 70 percent rating (65, rounded up), not an 80 percent rating. Use CCK Law’s VA Disability Calculator to apply VA math and estimate your new combined rating.
Tip: Do Not Forget Special Monthly Compensation and TDIU
A secondary rating for depression may add to benefits in ways that go far beyond a simple rating increase. For example, SMC and TDIU.
- Special Monthly Compensation (SMC): If a condition (e.g., cancer) rated 100 percent leads to depression rated 70 percent, the veteran meets the two rating requirements for SMC(s), which pay significantly more than total disability. Alternatively, if the veteran’s new condition means that they need help with activities of daily living (preparing food, dressing, taking medication, etc.), they may qualify for Aid & Attendance.
- If a secondary condition helps keep a veteran from being able to work, then they may qualify for individual unemployability (TDIU).
TDIU and SMC can have complex requirements, and VA often makes mistakes with effective dates (back pay). Consider reaching out to an experienced, VA-accredited appeals law firm for assistance.

What Primary Conditions Often Lead to Depression as a Secondary VA Disability?
We have seen a wide range of already service-connected conditions lead to secondary depression, including musculoskeletal injuries (e.g., back, shoulder, or knee conditions), migraines, sleep apnea, tinnitus, and more.
Generally, these conditions cause or aggravate depression through avenues like chronic pain, disrupted sleep, and limited mobility and independence.
“Chronic pain can wear a person down day after day, which can lead to depression,” says Bradley Hennings, a former Veterans Law Judge at VA and now a partner at CCK Law. “The constant ringing of tinnitus can disrupt sleep and concentration, affecting mood. And sleep apnea, which robs you of rest, is closely associated with depressive symptoms.”
Ways that conditions like these can lead to depression as a secondary VA disability include:
- Migraine — Frequent, severe migraines can interfere with a veteran’s ability to work, socialize, and spend time with loved ones, and this disruption can contribute to depression over time.
- Sleep apnea — Sleep apnea repeatedly interrupts a veteran’s sleep, and poor sleep is closely tied to mood disorders such as depression.
- Tinnitus — Constant ringing or buzzing in the ears can cause ongoing stress, frustration, and difficulty concentrating, all of which can lead to depression.
- Chronic pain — Chronic pain has no VA diagnostic code of its own, but research shows that persistent pain can alter brain chemistry in ways linked to depression, anxiety, and cognitive difficulties.
- TBI — A traumatic brain injury can bring on mood changes, memory problems, and sleep disruption, all of which are closely associated with depression.
- Other primary conditions that we have seen connected to secondary depression include diabetes, cancer, gastrointestinal disorders, and hearing loss, among others.
This list is not exhaustive. A vast array of disabilities can cause or contribute to depression, and veterans who suspect this is the case for their claim should consider discussing their symptoms with a treating provider or filing for depression as a secondary VA disability.
How Do I Prove Secondary Service Connection for a VA Disability?
Secondary service connection allows VA to compensate a veteran for a condition that was caused or made worse by an already service-connected disability, rather than by military service directly. Under 38 CFR § 3.310, veterans generally need to show three things to pursue a secondary depression claim:
- A current diagnosis of depression from a doctor or mental health provider.
- A primary condition that is already service connected, since secondary service connection cannot attach to a condition VA has not yet rated.
- A nexus opinion connecting the depression to the primary condition, often from your own medical professional. (This is not strictly necessary if you have strong treatment records or favorable C&P exam results, but is highly recommended.)
“That third piece is usually where claims stall,” says Bradley Hennings. “A strong nexus opinion from a medical professional should explain how your condition caused or worsened your depression.”
Veterans should keep in mind that an effective nexus opinion typically uses some variant of the phrase “at least as likely as not” (i.e., a 50 percent probability or greater) and explains the medical reasoning connecting the two conditions, rather than offering only a bare conclusion.
How Do I File for Depression as a Secondary VA Disability?
Veterans can generally follow these steps to file a secondary depression claim:
- Obtain a diagnosis — See a doctor or mental health provider for a formal diagnosis of depression.
- Seek a medical nexus opinion — Find a medical professional willing to provide a nexus opinion connecting the veteran’s primary condition to their depression.
- File VA Form 21-526EZ — List the secondary depression claim alongside the primary condition it stems from.
- Attend a Compensation & Pension (C&P) exam, if VA schedules one — Clearly describe how the two conditions relate during the exam.
VA often schedules a C&P exam to assess depression, particularly in the absence of an existing medical nexus opinion. During such an exam, the examiner will usually complete a Disability Benefits Questionnaire (DBQ), asking the veteran questions about symptom frequency, treatment history, and how depression affects their daily functioning.
Veterans should also be sure to include any other relevant evidence in their claim, including medical records or lay statements attesting to the veteran’s depression symptoms and how they might be related to their primary condition.
“Your own experience matters, too,” says Bradley Hennings. “Treatment records, statements from family, and accounts from those you served with can all help show how your depression developed and how it affects your daily life.”
Veterans who need more time to gather this evidence might consider submitting a VA Intent to File first, which locks in an earlier effective date for up to 12 months while the claim comes together.

What Happens if VA Denies My Secondary Depression Claim?
Veterans who disagree with a VA decision on a secondary depression claim generally have one year to file an appeal through one of three review options:
- Supplemental Claim — File new and relevant evidence for VA to review.
- Higher-Level Review — Request that a senior reviewer take a fresh look at the same evidence.
- Appeal to the Board of Veterans’ Appeals (BVA) — Request review by a Veterans Law Judge, with or without a hearing.
Each option carries different timelines and rules for submitting evidence, so the right choice often depends on whether new evidence is available. If the appeal is successful and the secondary depression claim is ultimately approved, the veteran will generally receive retroactive compensation paid back to the effective date of the original claim.
Veterans can hire VA-accredited law firms to assist with denials. Learn what VA accreditation and legal experience can bring to appeals.

Frequently Asked Questions
Can depression be secondary to tinnitus, sleep apnea, or migraines?
Yes, depression is commonly claimed as secondary to conditions like tinnitus, sleep apnea, or migraines. This is because each of these conditions can disrupt sleep, cause ongoing stress, and interfere with daily life, all of which can lead to depression.
How does adding secondary depression change my combined VA disability rating?
Rather than simply adding percentages together, VA combines ratings using its own combined ratings table, which applies each additional disability to the veteran’s remaining overall efficiency rather than to the full percentage (these calculations are often referred to as “VA math”).
With this in mind, adding a secondary depression rating can meaningfully raise a veteran’s combined VA disability rating and may even help support a claim for total disability based on individual unemployability (TDIU) when the combined ratings meet the schedular threshold.
Do I need a nexus letter for a secondary depression claim?
While a nexus letter is not always legally required, it is one of the most effective forms of evidence for a secondary depression claim. Without one, VA generally schedules a C&P exam to obtain its own medical opinion on the connection.
Do I need a new C&P exam for a secondary depression claim?
Not always. If a veteran files a Fully Developed Claim with a private nexus letter and diagnosis already in hand, VA may decide the claim without scheduling a new exam. If the evidence is incomplete, VA will typically schedule a C&P exam for depression before deciding the claim.
Can I get a separate rating for secondary depression if I already have PTSD or another mental health rating?
Generally, no. VA’s rules against pyramiding prevent a veteran from receiving two separate ratings for the same symptoms. If depression and an existing mental health condition share overlapping symptoms, VA will typically rate them together under a single mental health evaluation rather than adding a second, separate rating.
