DSM-5-TR for Clinical: New T/Z Codes, Racism Impact, Suicidal Behavior Codes

ASWB began testing DSM-5-TR in January 2024, and Clinical candidates feel it most. The exam now expects you to know prolonged grief disorder, the new suicidal-behavior and NSSI codes, and — most tested of all — how racism and discrimination shape diagnosis.

This guide covers only what changed, so you can patch your DSM-5 notes instead of relearning everything. Drill it with an ASWB Clinical practice test focused on Assessment and Planning.

What Changed in DSM-5-TR

ChangeWhat it isHow the exam tests it
Prolonged grief disorder addedPersistent intense grief beyond 12 months (adults) with identity disruption, avoidance, intense longingDifferentiate from MDD and adjustment disorder by trigger (death of close person) plus duration
Suicidal behavior T14.91 + Z codesT14.91 current attempt; Z91.5 personal history of self-harm; R45.851 suicidal ideationDocumentation and risk vignettes — these are codes, not diagnoses
NSSI Z91.5 clarifiedNon-suicidal self-injury history code; NSSI disorder remains in Section IIIDistinguish NSSI (no intent to die) from attempt by intent, lethality, planning
Racism and discrimination impact statementsText added across disorders on how oppression shapes presentation and assessmentVignettes where the correct answer avoids pathologizing adaptive mistrust or grief
Gender and culture language updatesRevised terminology, cultural formulation emphasisMSE interpretation questions — adjust for culture before diagnosing

T14.91, Z91.5, R45.851: Codes, Not Diagnoses

The single most tested trap: a vignette asks for the diagnosis and lists a T or Z code among the options. Codes describe factors influencing care, not disorders. Pick them only when the question asks what to document or add alongside a diagnosis — for example, MDD with T14.91 after an attempt, or Z91.5 on a returning client with NSSI history to flag risk.

  • T14.91: suicide attempt, current — use during the encounter when an attempt occurred
  • Z91.5: personal history of self-harm — history flag, drives safety planning
  • R45.851: suicidal ideation — symptom code when ideation is the focus of care
  • Z91.81: personal history of military trauma and other psychosocial risk codes — exam loves these as distractors

Prolonged Grief vs MDD vs Adjustment

FeatureProlonged grief disorderMajor depressionAdjustment disorder
TriggerDeath of a close personAny or noneIdentifiable stressor within 3 months
Core feelingLonging, yearning, preoccupation with the deceasedAnhedonia, worthlessness, pervasive low moodDisproportionate distress or impairment tied to stressor
Duration12+ months adults, 6+ months children2+ weeksResolves within 6 months of stressor ending
Self-viewIdentity disruption tied to lossGlobal worthlessness and guiltVaries, tied to stressor

Exam cue: if grief is the center and the timeline passes 12 months with functional impairment, prolonged grief beats MDD even when depressive symptoms overlap.

How Racism and Discrimination Show Up

Expect at least one vignette where a client's guarded behavior, somatic complaints, or anger reflects lived experience of discrimination rather than pathology. The correct move follows a fixed order:

  1. Apply the cultural formulation — consider identity, stressors, supports, and clinician-client differences before labeling.
  2. Rule out environmental causes — housing, policing, workplace discrimination, immigration stress.
  3. Adjust the MSE — guarded in context is adaptive; flat affect across contexts is clinical.
  4. Diagnose conservatively and document cultural factors influencing presentation.

Wrong answers pathologize first (paranoid traits, oppositional traits) or ignore culture entirely. Right answers name the impact and choose collaboration: ask, validate, adapt.

5-Minute Drill

For each differential you miss this week, write one line: trigger, duration, core feature. Grief needs a death plus 12 months. MDD needs 2 weeks of anhedonia or low mood plus 4 more symptoms. Adjustment needs a stressor within 3 months. NSSI needs no intent to die. Attempt needs intent plus action. That card alone answers most DSM questions on the Clinical exam.
