Diagnostic Code 9433 · 38 CFR §4.130
Persistent depressive disorder (formerly called dysthymia) is a chronic form of depression lasting at least two years. While individual symptoms may be less intense than in major depressive disorder, the unrelenting nature of the condition — feeling low more days than not for years — creates significant cumulative impairment. Symptoms include depressed mood, poor appetite or overeating, insomnia or excessive sleeping, low energy, poor concentration, and feelings of hopelessness. Veterans may develop persistent depressive disorder during prolonged deployments, through accumulated military stressors, or as a secondary effect of service-connected physical conditions. The VA rates it under the General Rating Formula for Mental Disorders at 38 CFR 4.130.
| Rating | Criteria |
|---|---|
| 0% | Diagnosed but symptoms are not severe enough to impair occupational or social functioning. |
| 10% | Mild chronic depressive symptoms that decrease work efficiency only during stressful periods, or symptoms managed by continuous medication. |
| 30% | Persistent low mood causes occasional dips in work efficiency, intermittent difficulty performing tasks, chronic sleep problems, or mild memory issues. |
| 50% | The chronic nature of the depression reduces reliability and productivity. Difficulty sustaining motivation, maintaining effective relationships, and following through on complex tasks are persistent problems. |
| 70% | Years of persistent depression have caused deficiencies in most areas — work, family relationships, judgment, and emotional regulation. Near-continuous depressed mood makes independent functioning very difficult. |
| 100% | Total occupational and social impairment due to pervasive, unremitting depression that prevents any meaningful work, self-care, or social engagement. |
A diagnosis from a mental health professional documenting depressive symptoms persisting for at least two years is required. Treatment records showing long-term therapy, counseling, or medication management demonstrate the chronic nature of the condition. Medication records showing sustained antidepressant use support the ongoing severity. Buddy statements from family describing the persistent low mood, reduced energy, and social withdrawal over time are valuable. If claiming secondary to a service-connected condition, a medical nexus opinion is needed.
Major depressive disorder involves discrete episodes of severe depression. Persistent depressive disorder is a chronic, lower-grade depression lasting at least two years. Both are rated under the same formula. Some people experience both — a persistent baseline of depression with periodic major depressive episodes layered on top.
The VA rates all mental health conditions together under one combined evaluation. Having multiple diagnoses can support a higher rating by demonstrating a broader range of symptoms and greater total impairment.
