Post-traumatic stress disorder has moved from the margins to the centre of the disability claims landscape.

For first responders, healthcare workers, military and veterans, and a growing range of frontline professionals, trauma exposure is now recognized as an occupational hazard rather than an unfortunate consequence.

That recognition has changed the volume of PTSD claims reaching insurers, employers, and the legal community. It has also, sometimes, oversimplified them. The PTSD diagnosis is treated as if it answers the disability question - which it does not. The disability question is, and has always been, a functional one.

Why PTSD Is Genuinely Difficult To Assess

PTSD does not present uniformly, and it rarely presents the way the diagnostic criteria might lead a non-specialist to expect.

• Symptom variability over time. PTSD symptoms can fluctuate significantly across days, weeks, and even within a single session. Symptoms can also be over-presented under perceived threat to the claim.
• Avoidance that reads as disengagement. Avoidance is a core symptom of PTSD - and in a clinical setting, it can present as missed appointments, vague responses, or a muted presentation. To an inexperienced reviewer, that can read as low motivation rather than clinical signal.
• Hypervigilance that reads as anxiety or irritability. The arousal symptoms often look like generalized anxiety or anger management problems and can be misattributed without a trauma-informed lens.
• High comorbidity. PTSD frequently co-occurs with depression, substance use, chronic pain, and TBI. Each interacts in ways a single-condition lens cannot capture.
• Single-session limitations. A single point-in-time interview cannot, by itself, capture variability across a working week. For complex presentations, multi-session or longitudinal data is meaningfully more accurate.
  

Why Diagnosis Isn't The Answer To The Disability Question

Two claimants with the same DSM-5-TR PTSD diagnosis can be in entirely different functional positions. One may be working full-time in a modified role with effective treatment. Another may be unable to sustain a one-hour meeting.

Treating diagnosis as the answer to the disability question produces predictable problems: inconsistent decisions, RTW plans that are too ambitious or too conservative, and disputes that become protracted because the medical record doesn't contain the functional evidence the decision-maker needs.

What Good PTSD Assessment Looks Like

A defensible, decision-grade PTSD assessment typically includes:

• A trauma-informed clinical approach - assessors trained in trauma physiology who can elicit information without retraumatizing and interpret presentation as clinical data
• Multi-source data - primary care, mental health treatment, ER records, workplace incident reports, and collateral interviews with treating providers
• Functional evaluation - direct assessment of tolerance, regulation, social functioning, and the specific demands of the occupational role, not just symptom counts
• Comorbidity consideration - explicit assessment of co-occurring depression, substance use, chronic pain, and where indicated TBI, with analysis of how they interact
• Where indicated, multi-session assessment for fluctuating presentations
• Reports that distinguish clearly between diagnosis and functional capacity, written for the audience that needs to act on them
  

Return-to-Work Planning for PTSD

RTW in a PTSD file is a different exercise than after a musculoskeletal injury, and different again from generalized mental health files.

• Triggers and tolerance must be mapped specifically - environmental, interpersonal, content-based
• Role redesign often matters more than gradual hours. A graduated return that reduces hours but maintains the same triggers will frequently fail
• The clinical team and the workplace need to be working from the same picture
• Setbacks should be anticipated and responded to clinically, not treated as failure

What This Means For Legal Teams

For plaintiff and defence counsel, the difference between an opinion-based and an evidence-based PTSD assessment can determine the outcome. Markers of reports that hold up under scrutiny:

• Methodology fully documented - records reviewed, tests administered, sessions conducted, collateral used
• Diagnosis and function clearly separated, with the reasoning between them transparent
• Symptom variability addressed directly, with the assessor explaining how it was managed
• Co-morbidities addressed individually and in interaction
• Written so the audience can act on it without further clinical translation
  
  

Closing

PTSD Awareness Month is a useful moment to take stock of how PTSD files are being assessed and managed. For files that are stalled, contested, or producing repeated RTW failures, the assessment lens is often the variable that has not yet been adjusted.

At SOMA, our multidisciplinary teams include psychiatrists, psychologists, and other specialists with the trauma-informed expertise and disability-context understanding these files require. Reach out at referrals@somamedical.com.
