ICD-10 Code F44.0 – Dissociative amnesia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F44.0 – Dissociative amnesia
What it is
Dissociative amnesia is a loss of autobiographical memory, usually for important personal information, that is too extensive to be explained by ordinary forgetfulness. You should code it when the record documents amnesia linked to dissociation.
Clinical signs
Typical findings include inability to recall specific events, periods, or identity-related information, often after stress or trauma. Clinical features vary; refer to documentation.
When to use this code
Use F44.0 when the provider diagnoses dissociative amnesia and documents memory loss not better explained by a neurologic disorder, substance use, or another mental condition. It may also apply when the note describes localized or generalized autobiographical memory gaps. Check documentation if the cause is unclear.
Do not use for
Do not use this code for ordinary forgetfulness, dementia, delirium, or amnesia clearly due to head injury, seizures, drugs, or alcohol. If the chart does not support dissociation, code the documented condition instead.
Coding tip
Confirm the provider explicitly links the memory loss to dissociation, and code any documented associated condition separately when appropriate.
