Quick reference
- When to use
- Use F44.81 when the client presents with dissociative symptoms consistent with Dissociative Identity Disorder. These diagnoses require careful, longitudinal assessment. Rule out malingering, substance effects, and other conditions.
- Duration
- Dissociative disorders are typically chronic conditions rooted in early trauma. Assessment often requires multiple sessions. Document dissociative symptoms with standardized measures (DES-II).
- Session codes
- Pair with CPT 90837 (60-min preferred for complex dissociative work). 90791 for evaluation. 90785 for interactive complexity. Treatment is typically long-term. Safety planning is essential.
- Key indicators
- Identity disruption • Dissociative amnesia • Depersonalization/derealization • Identity alteration • Gaps in recall of everyday events • Often linked to trauma history
What F44.81 represents
DID involves a disruption of identity characterized by two or more distinct personality states, involving discontinuity in sense of self, agency, affect, behavior, consciousness, memory, perception, cognition, or sensory-motor functioning.
Key diagnostic criteria
- Disruption of identity with 2+ distinct personality states (may be described as possession experience)
- Recurrent gaps in recall of everyday events, personal information, or traumatic events
- Causes significant distress or impairment
- Not part of a cultural or religious practice
- Not attributable to substances or medical condition (e.g., seizures)
Documentation essentials
Document identity disruptions, amnesia episodes, functional impact, and trauma history. Note switches observed in session.
Differential diagnosis
Distinguish from PTSD (dissociative subtype), BPD, psychotic disorders, factitious disorder, and malingering.
Treatment planning
Phase-oriented treatment: stabilization, trauma processing, integration. Long-term psychotherapy. Avoid regression-focused approaches.
Insurance & billing
May face skepticism. Thorough documentation is essential. Supports long-term treatment.
Updates & changes
DSM-5 clarified that identity disruption may be self-reported or observed. Added possession form.
Documentation pitfalls
Don't rush to confirm or deny the diagnosis. Careful longitudinal assessment is essential.
