# Can I get SSDI for PTSD?

The SSA uses the paragraph A criteria (medical documentation of PTSD) plus paragraph B (marked limits in two, or extreme in one, of the four mental functioning areas) or paragraph C (serious and persistent).

**Direct answer:** Yes — post-traumatic stress disorder can qualify for SSDI when it meets SSA Listing 12.15 for trauma- and stressor-related disorders, which requires documented symptoms plus marked limits in specified areas of mental functioning.

## What listing applies?
Listing 12.15 (trauma- and stressor-related disorders).

## What evidence matters?
Longitudinal mental health treatment records, third-party function reports, and evidence of exposure to trauma plus persistent symptoms.

## What if I don't meet 12.15?
The SSA evaluates residual functional capacity — restrictions on concentration, social contact, and stress tolerance can rule out sustained work.
