Code Description

ICD-10 F44.1 is a billable code used to indicate a diagnosis of dissociative fugue.

Key Diagnostic Point:

Dissociative fugue is a subtype of dissociative disorder characterized by sudden, unexpected travel away from home or customary work locations, accompanied by an inability to recall one's past (personal history). This condition often arises in response to severe stress or trauma, such as emotional or physical abuse, natural disasters, or significant life changes. Individuals may assume a new identity or engage in complex behaviors without awareness of their actions. The fugue state can last for hours, days, or even longer, and upon recovery, the individual typically has no recollection of the events that occurred during the fugue. The condition is often associated with other mental health disorders, including anxiety disorders, PTSD, and depression, making accurate diagnosis and treatment essential. Treatment may involve psychotherapy, cognitive-behavioral therapy, and anxiety management techniques to address underlying issues and promote coping strategies.
