PTSD and SSDI Eligibility: How Social Security Evaluates PTSD Claims

Published:

You can get approved for Social Security Disability Insurance (SSDI) for post-traumatic stress disorder (PTSD) if you meet the Social Security Administration's (SSA) disability requirements. A diagnosis is not enough, though, and neither is a VA disability rating for PTSD. You must show how severely PTSD affects your ability to work.

PTSD is evaluated in the SSA’s Listing of Impairments under Listing 12.15, which covers the medical and functional requirements for trauma- and stressor-related disorders.

You also need qualifying work history to get SSDI, and the disability must be expected to last at least 12 months or result in death. Without a qualifying work history, you may be able to qualify for Supplemental Security Income (SSI) with PTSD if you meet SSI rules.

Learn more about eligibility rules for SSDI and SSI.

Medical Evidence for PTSD Under Listing 12.15

The SSA needs objective medical evidence from an acceptable medical source to establish PTSD as a medically determinable impairment (MDI). Medical evidence may include a doctor’s observations and mental health exam findings. If your records don’t have enough detail, the SSA may schedule a consultative examination with a psychologist or psychiatrist.

Required Medical Criteria

SSA rules say your medical documentation must show these five characteristics:

  1. Exposure to actual or threatened death, serious injury, or violence
  2. Unwanted memories, dreams, or flashbacks of the traumatic event
  3. Avoiding people, places, or situations that remind you of the traumatic event
  4. Changes in mood and behavior, such as feeling emotionally numb or losing interest in activities
  5. Feeling constantly on alert, being easily startled, or having trouble sleeping

PTSD Treatment Records

Your medical records may include mental health evaluations, interviews, and notes from a doctor or therapist. These records can show which symptoms and medical findings support your PTSD diagnosis.

Since different appointments likely cover different concerns, every note doesn't need to address all five characteristics.

How the SSA Rates PTSD Limitations for SSDI 

The SSA looks at how PTSD affects four areas of mental functioning. It considers what you can do on your own and when you need help. For an SSDI claim, how severely your PTSD symptoms limit you matters more than how many symptoms you have. 

This table shows the four areas of mental functioning and possible effects.

SSA Mental-Function Area PTSD-Related Symptoms Possible Functional Effects
Understanding, remembering, or applying information Intrusive memories, tiredness from poor sleep Trouble remembering instructions, following steps, or using what you've learned
Interacting with others Feeling constantly on alert, avoidance, irritability Difficulty talking with coworkers, answering a supervisor's questions, or responding to feedback
Concentrating, staying on task, or maintaining pace Flashbacks, sudden fear or anxiety, unwanted memories Losing focus, needing extra time to finish tasks, or falling behind at work
Handling changes and managing emotions and behavior Intense anxiety or irritability when reminded of the trauma Difficulty managing emotions or handling unexpected changes at work

‍

Marked and Extreme Limitations

The SSA rates your limitations in each of the four areas as none, mild, moderate, marked, or extreme. To meet the listing's requirements, you must have “marked” limitations in at least two areas or an extreme limitation in one area. 

A marked limitation means you have serious trouble doing activities in that area without help or doing them consistently over time. An extreme limitation means your symptoms are so severe that you can’t do activities in that area by yourself or consistently. Reviewers, starting with disability examiners at your state’s Disability Determination Services (DDS), use the evidence in your claim to determine these ratings. 

How PTSD Affects Your Ability to Work Consistently

DDS reviewers consider whether you can work a regular schedule, meaning eight hours a day, five days a week, or an equivalent schedule. Being able to complete a task sometimes doesn't mean you can do it consistently throughout a workweek.

For example, you might write invoices accurately when things are quiet. But if flashbacks interrupt you several times during a shift, you may need extra breaks, lose track of your work, or struggle to finish on time.

Reviewers evaluate how often your symptoms interrupt work, how long those interruptions last, and how much time you need to recover, and a medical source statement from your therapist can describe all three. They consider how these difficulties affect your ability to handle your workload and maintain a regular work schedule.

How Reviewers Evaluate Changing PTSD Symptoms

PTSD symptoms can improve or worsen depending on trauma reminders, your surroundings, and how well treatment works. Records from different appointments help reviewers understand these changes over time, which a one-time consultative examination can’t show. 

Reviewers consider what triggers worsening symptoms, how often and how long they last, and what difficulties remain when your symptoms improve.

For example, a provider’s notes might say that you're sleeping better and keeping up with daily activities for several months. But after a reminder of the trauma triggers flashbacks, their notes may describe more nightmares, avoiding travel, and trouble leaving home.

Differences between appointments don't necessarily mean your records conflict. Improvement doesn't always mean you can work, and worsening symptoms alone don't mean you qualify for SSDI. Reviewers also consider your response to treatment, the support you need, and any ongoing limitations.

Qualifying for SSDI With Serious and Persistent PTSD 

The SSA has another way to qualify for SSDI under Listing 12.15 if you have serious and long-lasting PTSD. You must still meet the five medical criteria discussed earlier, but different requirements apply to how the condition limits your ability to function.

To qualify this way, the evidence must show that:

  • You've had PTSD for at least two years. 
  • You rely on ongoing treatment, therapy, support, or a highly controlled daily environment to help reduce your symptoms.
  • You can barely handle changes to your normal routine, even with treatment or support.

For example, you might be able to prepare meals and do household chores when a family member helps you follow a familiar schedule. But when you don’t have help or the routine changes, your symptoms flare, making it difficult to manage those tasks.

Can You Get SSDI for PTSD That Doesn’t Meet Listing 12.15? 

Even if your PTSD doesn’t meet Listing 12.15 in the Blue Book, you may still qualify for SSDI. Reviewers can assess your residual functional capacity (RFC), which is the most you can do despite your limitations.

A medical source statement from your psychiatrist or therapist can support your RFC by showing how PTSD symptoms affect specific work tasks and demands. It can help determine if you can do your previous work or switch to another type of work. 

Our article on how to prove a mental health disability explains mental RFC assessments in more detail.
