PTSD and Social Security Disability
What Social Security's listing 12.15 requires for trauma- and stressor-related disorders, how these claims are actually decided, and what evidence carries them.
PTSD claims turn on the same four areas of functioning as other mental impairments, but they carry a specific evidentiary difficulty: the symptoms that most limit work are often the ones people are least willing to describe.
The listing: 12.15
Paragraph A requires medical documentation of all five:
- Exposure to actual or threatened death, serious injury, or violence
- Subsequent involuntary re-experiencing of the traumatic event — flashbacks, intrusive memories, nightmares
- Avoidance of external reminders
- Disturbance in mood and behavior
- Increases in arousal and reactivity — exaggerated startle, sleep disturbance
Paragraph B requires extreme limitation in one, or marked limitation in two, of the four areas of mental functioning: understanding and applying information; interacting with others; concentrating, persisting, or maintaining pace; and adapting or managing oneself.
Paragraph C covers serious and persistent disorders over at least two years where treatment or a structured setting keeps symptoms manageable and adjustment outside it stays marginal.
What decides these claims
Hypervigilance and startle response bear directly on interacting with others and on adapting. Someone who cannot sit with their back to a door, or who reacts severely to unexpected noise, is describing a real barrier to most workplaces.
Concentration and intrusive symptoms bear on pace. Time lost to intrusive thoughts is off-task time, and off-task time above roughly ten to fifteen percent generally eliminates competitive employment.
Sleep disturbance compounds everything else. Chronic nightmares and insomnia produce daytime fatigue and cognitive impairment that are separately work-limiting.
Avoidance is the one most often understated in the record. Not driving past a particular intersection, not going out after dark, not tolerating crowds — these get normalized by the person living with them and never make it into a chart.
Building the record
Get into consistent treatment, even if it’s hard. Trauma treatment has high dropout rates for reasons intrinsic to the condition. A record showing repeated engagement — even with gaps — is far stronger than an untreated diagnosis. Where symptoms caused a gap, make sure the chart says so.
Ask for a mental residual functional capacity statement. Your provider rating the paragraph B areas and estimating absences and off-task time. This is the document that connects the diagnosis to the vocational question.
Use third-party statements. A spouse describing the night terrors, the checking of locks, the canceled family events. These are permitted evidence and consistently underused.
Document failed work attempts. Dates, employer, what happened. A pattern of jobs ending after weeks is evidence about sustainability that no clinical note can substitute for.
Address substance use directly if it applies. If drug or alcohol use is material to the disability determination, the claim fails. Documented periods of sobriety with continued symptoms are what separate the two, and they are worth a lot.
A note on describing symptoms
Function reports get compared against treatment notes, and inconsistencies get used against claimants. The most common inconsistency in PTSD files is understatement — people minimize in the clinical setting out of habit or shame, then describe things accurately on the disability paperwork, and the mismatch looks like exaggeration.
The fix is describing things the same way in both places, including the parts that are uncomfortable to say out loud.
Common questions
Do I need a VA disability rating to qualify?
No, and a VA rating does not decide a Social Security claim — the two agencies use different standards. That said, VA records are medical evidence and are considered. Veterans rated 100% permanent and total do receive expedited processing at Social Security.
Does PTSD have to come from military service?
No. Listing 12.15 covers trauma- and stressor-related disorders generally. Assault, abuse, accidents, medical trauma, and witnessing violence all fall within it.
What if I have PTSD and a physical injury from the same event?
Social Security is required to consider the combined effect of all impairments. Cases where neither the physical nor the psychological condition would be disabling alone are frequently approved on the combination.
