Major Depressive Disorder
✓ VERIFIED AGAINST 38 C.F.R.§ 4.130 (Mental disorders) · reviewed 2026-05-15 · ClaimRecon Editorial Team
Major Depressive Disorder is rated by the U.S. Department of Veterans Affairs under DC 9434 of 38 CFR § 4.130, DC 9434 across 6 severity tiers (0% / 10% / 30% / 50% / 70%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303. This condition is frequently rated as secondary to Sleep Apnea or GERD under 38 C.F.R. § 3.310.
OVERVIEW
Persistent depressed mood or loss of interest in activities, accompanied by changes in appetite, sleep, energy, concentration, and self-worth. Episodes must last at least two weeks and represent a change from previous functioning.
RATING CRITERIA (6 LEVELS)
0%
A mental condition has been formally diagnosed, but symptoms are not severe enough either to interfere with occupational and social functioning or to require continuous medication.
10%
Occupational and social impairment due to mild or transient symptoms which decrease work efficiency and ability to perform occupational tasks only during periods of significant stress, or symptoms controlled by continuous medication.
30%
Occupational and social impairment with occasional decrease in work efficiency and intermittent inability to perform tasks due to depressed mood, anxiety, chronic sleep impairment, and mild memory loss.
50%
Occupational and social impairment with reduced reliability and productivity due to flattened affect, panic attacks more than weekly, memory impairment, impaired judgment, disturbances of motivation and mood, and difficulty in establishing and maintaining effective relationships.
70%
Occupational and social impairment with deficiencies in most areas (work, family, judgment, thinking, mood) due to suicidal ideation, near-continuous depression affecting ability to function, impaired impulse control, neglect of hygiene, and inability to maintain effective relationships.
100%
Total occupational and social impairment due to gross impairment in thought processes, persistent danger of hurting self or others, inability to perform activities of daily living, disorientation, and severe memory loss.
KEY EVIDENCE TO GATHER
-Service treatment records showing injury or complaints
-Imaging (X-ray, MRI, CT)
-Range of motion measurements
-Flare-up documentation per Sharp v. Shulkin
-Buddy statements describing limitations
-Prescription history
-Physical therapy records
-Employment impact documentation

C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
INSIDE THE RATING DECISION
How Raters Evaluate Depression
Secondary Connection
Depression is frequently granted secondary to chronic pain conditions under 38 C.F.R. 3.310. In actual rating decisions, raters grant secondary service connection when medical evidence links chronic pain to mental health symptoms. All mental health conditions receive a single combined rating.
30% to 70% Progression
Rating decisions show a common pattern: initial grant at 30% (symptoms not severe enough to interfere with occupational functioning), followed by increase to 70% when symptoms worsen to include difficulty adapting to work, memory impairment, and flattened affect. The key evidence that drives the increase is typically a new C&P exam documenting worsened symptoms.
What This Means
If your depression is secondary to a service-connected condition like chronic back pain, ensure your treating provider documents the connection. The single-rating rule means your PTSD, depression, and anxiety symptoms all combine into one rating under whichever DC the rater selects.
