SSDI Criteria for Post-Traumatic Stress Disorder

Yes, post-traumatic stress disorder (PTSD) can qualify you for Social Security Disability Insurance (SSDI). SSA evaluates PTSD under Listing 12.15, the Blue Book category for trauma- and stressor-related disorders, which looks at both the clinical aftermath of trauma and how far symptoms erode the mental functions work demands.

The condition is common among veterans, assault survivors, accident victims, and first responders, but the listing is neutral about the source of the trauma. What SSA measures is documented exposure, the symptom pattern that followed, and the resulting functional limits.

Documenting the Trauma Itself

Listing 12.15A begins with medical documentation of exposure to actual or threatened death, serious injury, or violence. The Blue Book's description of this category at 12.00B11 explains that this includes experiencing or witnessing a traumatic event, or learning of a traumatic event that occurred to a close family member or close friend.

The record needs to tie the diagnosis to a traumatic or stressful event through treatment notes from an acceptable medical source under 20 CFR 404.1513, such as a psychiatrist, psychologist, or other qualified clinician. Service records, police reports, and medical notes from the time of the event can support what the clinician later documents, but the listing is built on the clinical picture, not on paperwork alone.

The Five Findings Paragraph A Requires

Unlike most mental listings, which allow a choice of symptom clusters, 12.15A requires medical documentation of all of the following:

1. Exposure to actual or threatened death, serious injury, or violence.
2. Subsequent involuntary re-experiencing of the traumatic event, with the Blue Book giving intrusive memories, dreams, and flashbacks as examples.
3. Avoidance of external reminders of the event.
4. Disturbance in mood and behavior.
5. Increases in arousal and reactivity, with examples including an exaggerated startle response and sleep disturbance.

Each element must appear in the record, which is why longitudinal treatment notes matter so much. A clinician who records nightmares, avoidance of the place where the trauma happened, persistent anger or numbness, jumpiness, and disrupted sleep has mapped all five findings; a single note saying "PTSD, stable on medication" has not.

Paragraph B: Marked Limits in Two of Four Areas

Paragraph B requires extreme limitation of one, or marked limitation of two, of the four areas of mental functioning defined at 12.00E:

1. Understand, remember, or apply information, such as learning procedures, following multi-step instructions, and using judgment.
2. Interact with others, such as cooperating with coworkers, handling conflict, responding to criticism, and keeping social contact free of excessive irritability, aggression, or suspiciousness.
3. Concentrate, persist, or maintain pace, such as initiating tasks, staying on task, keeping pace, and sustaining attendance.
4. Adapt or manage oneself, such as regulating emotions, managing psychologically based symptoms, and adapting to changes in the workplace.

SSA rates each area on the five-point scale at 12.00F, running from none to extreme. Marked means the area is seriously limited when used independently, appropriately, effectively, and on a sustained basis, and extreme means you cannot function in that area on that sustained basis. Hypervigilance, anger outbursts, and avoidance of other people usually hit interacting with others and adapting hardest, while intrusive memories and poor sleep hit concentration and pace.

Paragraph C: Serious and Persistent PTSD

For PTSD dampened by treatment but with a long and fragile history, paragraph C applies under 12.00G. It requires a medically documented history of the disorder over at least 2 years, plus both of the following:

1. Ongoing medical treatment, mental health therapy, psychosocial support, or a highly structured setting that diminishes the symptoms and signs.
2. Marginal adjustment, meaning minimal capacity to adapt to changes or to demands that are not already part of daily life.

At 12.00G2c, marginal adjustment shows up as deterioration when demands rise, inability to function outside the home or a more restrictive setting without substantial support, hospitalizations, or work absences that make sustained employment impossible. The rule at 12.00G2b also says that gaps in treatment caused by the disorder itself cannot be counted against you.

How SSA Handles Trauma Claims That Involve Other Programs

Many PTSD claimants already have a Department of Veterans Affairs rating. Under 20 CFR 404.1504, decisions by the VA and other agencies are not binding on SSA because each program applies its own rules, and for claims filed on or after March 27, 2017, SSA will not provide analysis of those decisions in its own determination. SSA will, however, consider all the supporting evidence underlying the other agency's decision that is received in your claim, so VA treatment records and examination reports remain valuable evidence.

Substance Use and PTSD

Substance use often travels with PTSD, and SSA addresses it directly at 20 CFR 404.1535. If there is medical evidence of drug addiction or alcoholism, the agency must decide whether that use is a contributing factor material to the determination of disability.

The key factor, stated in the regulation, is whether SSA would still find you disabled if you stopped using drugs or alcohol. In other words, the agency asks which of your current limitations would remain, and a PTSD claim built on solid clinical evidence of trauma symptoms can survive that analysis even when substance use is present.

If You Do Not Meet Listing 12.15

PTSD that falls short of the listing can still win at the later steps. SSA first considers medical equivalence under 20 CFR 404.1526, including the combined effects of PTSD with depression, anxiety, traumatic brain injury, or chronic pain.

The agency then assesses mental residual functional capacity under 20 CFR 404.1545 and proceeds to steps four and five of the evaluation at 20 CFR 404.1520, where age, education, and past work matter under the medical-vocational guidelines in 20 CFR Part 404, Subpart P, Appendix 2. Off-task time caused by flashbacks, absenteeism driven by sleep disturbance, and inability to tolerate supervision are the limitations that most often eliminate work at this stage.

The Nonmedical Rules You Must Also Pass

Every SSDI claim, including PTSD claims, requires disability insured status under 20 CFR 404.101 and 404.130. In 2026, one work credit is earned for each $1,890 in covered earnings, up to four credits per year, and most workers need 40 credits with 20 earned in the 10 years ending with the year their disability began.

At step one, earnings above the substantial gainful activity limit end the claim before the medical review starts. In 2026, that limit is $1,690 in average monthly earnings for non-blind claimants and $2,830 for claimants who are statutorily blind, under 20 CFR 404.1574.

Frequently Asked Questions

Is PTSD a qualifying disability for SSDI? Yes. SSA evaluates post-traumatic stress disorder under Listing 12.15 for trauma- and stressor-related disorders, which requires documented trauma exposure plus symptom and functional criteria, or a serious and persistent history under paragraph C.

Does a VA disability rating for PTSD guarantee SSDI approval? No. Under 20 CFR 404.1504, a Department of Veterans Affairs decision is not binding on SSA, but SSA will consider the underlying medical evidence supporting the VA decision as evidence in your claim.

Do I have to prove the traumatic event happened to get SSDI for PTSD? Yes. Listing 12.15A requires medical documentation of exposure to actual or threatened death, serious injury, or violence, which SSA notes can include learning of a traumatic event that occurred to a close family member or close friend.
