ICD-10 Code F44.89 – Other dissociative and conversion disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F44.89 – Other dissociative and conversion disorders
What it is
F44.89 identifies dissociative or conversion-type disorders that do not fit a more specific ICD-10-CM code. Use it when the record describes dissociation or neurologic-like symptoms without another defined category.
Clinical signs
Clinical features vary; refer to documentation. Records may note altered identity, memory disturbance, trance-like episodes, or neurologic symptoms such as weakness, numbness, or nonepileptic events.
When to use this code
Use this code when the clinician documents an “other” dissociative or conversion disorder and the presentation is not captured by a more specific F44 code. It may apply when symptoms are clearly documented but the subtype is not named. Check documentation if the note is vague or mixed with another mental health diagnosis.
Do not use for
Do not use this code if the record supports a more specific dissociative disorder, such as amnesia or fugue. Do not use it for symptoms better explained by a neurologic, substance-related, or intentional condition.
Coding tip
Assign F44.89 only when the provider explicitly documents an unspecified “other” dissociative or conversion disorder, and verify that a more specific F44 code is not available.
