Code Description

ICD-10 F44.6 is a billable code used to indicate a diagnosis of conversion disorder with sensory symptom or deficit.

Key Diagnostic Point:

Conversion disorder with sensory symptom or deficit is a mental health condition characterized by the presence of neurological symptoms that cannot be explained by medical or neurological conditions. Patients may present with sensory deficits such as loss of vision, numbness, or inability to speak, which are not attributable to any underlying physical cause. This disorder often arises in the context of psychological stress or trauma, where the individual may unconsciously convert emotional distress into physical symptoms. The symptoms can significantly impair daily functioning and may lead to increased anxiety, depression, or social withdrawal. Diagnosis typically involves a thorough clinical evaluation to rule out other medical conditions, and it may require collaboration with neurologists and mental health professionals. Treatment often includes psychotherapy, physical therapy, and anxiety management techniques to address both the psychological and physical aspects of the disorder.
