Depression (Major Depressive Disorder) and SSDI
Depression is the most common mental health basis for SSDI. Learn the paragraph B and C criteria the SSA uses to evaluate severity.
What the SSA Looks For
Depression is evaluated under Listing 12.04. The SSA uses "paragraph B criteria" — four areas of mental functioning: understanding/applying information; interacting with others; concentrating/persisting/maintaining pace; and adapting/managing oneself. You need extreme limitation in one area or marked limitation in two.
Common Reasons Claims Are Denied
- Claimant not in treatment or has gaps in psychiatric care
- Treating physician provides minimal notes — "doing okay on medication"
- SSA finds only moderate limitations rather than marked/extreme
- Claimant's activities of daily living appear inconsistent with claimed severity
How to Strengthen Your Appeal
Regular psychiatric treatment is essential. Your psychiatrist or therapist must document the four paragraph B functional areas in detail. A medical source statement (mental RFC) from your treating provider describing your specific work-related mental limitations is the most powerful evidence. If medication has not helped, document treatment-resistant depression clearly.
Key Medical Evidence Needed
- Psychiatric records with GAF scores or equivalent functional assessments
- Mental RFC / medical source statement from treating psychiatrist
- Therapist progress notes documenting functional decline
- Medication history showing treatment attempts and failures
- Records of hospitalizations or crisis interventions
- Third-party function reports from family members describing your daily functioning
Major depressive disorder is one of the most common bases for SSDI claims. The SSA takes mental health claims seriously when backed by consistent treatment and thorough functional documentation.
The Paragraph B Criteria
To meet Listing 12.04, you need extreme limitation in one or marked limitation in two of these four areas:
- Understanding, remembering, and applying information — Can you follow instructions? Learn new tasks? Apply previously learned information?
- Interacting with others — Can you cooperate with supervisors and coworkers? Handle criticism? Avoid conflict?
- Concentrating, persisting, or maintaining pace — Can you stay on task? Complete tasks at a reasonable pace? Avoid distraction?
- Adapting or managing oneself — Can you regulate emotions? Maintain personal hygiene? Respond to workplace changes?
The Paragraph C Criteria (Alternative Path)
Even if you don't meet paragraph B, you may meet paragraph C if you have a serious and persistent mental disorder with a documented history of at least 2 years AND you rely on ongoing mental health treatment to prevent decompensation AND you have minimal capacity to adapt to changes in environment or daily life demands.
