Code Description

ICD-10 F44.4 is a billable code used to indicate a diagnosis of conversion disorder with motor symptom or deficit.

Key Diagnostic Point:

Conversion disorder with motor symptom or deficit is a psychological condition characterized by the presence of neurological symptoms that cannot be explained by medical or neurological conditions. Patients may present with symptoms such as weakness, paralysis, abnormal gait, or tremors, which are inconsistent with recognized neurological diseases. The onset of these symptoms often follows a stressful event or psychological conflict, suggesting a link between psychological factors and physical manifestations. Diagnosis requires a thorough clinical evaluation to rule out other medical conditions, and symptoms must cause significant distress or impairment in social, occupational, or other important areas of functioning. Treatment typically involves a multidisciplinary approach, including psychotherapy, physical therapy, and sometimes medication to manage associated anxiety or depression. Understanding the interplay between psychological stressors and physical symptoms is crucial for effective management and recovery.
