Code Description

ICD-10 F44.7 is a billable code used to indicate a diagnosis of conversion disorder with mixed symptom presentation.

Key Diagnostic Point:

Conversion disorder with mixed symptom presentation is characterized by the presence of neurological symptoms that cannot be explained by medical or neurological conditions. These symptoms may include motor or sensory dysfunction, such as weakness, paralysis, abnormal gait, or sensory loss, and can also manifest as non-epileptic seizures or dissociative symptoms. The onset of these symptoms is often associated with psychological stressors or trauma, and they may fluctuate in severity. Patients may exhibit a range of symptoms that do not conform to known anatomical or physiological pathways, leading to significant distress and impairment in social, occupational, or other important areas of functioning. Diagnosis requires a thorough clinical evaluation to rule out other medical conditions, and the symptoms must not be intentionally produced or feigned. Treatment typically involves a multidisciplinary approach, including psychotherapy, physical therapy, and sometimes medication to manage associated anxiety or depressive symptoms.
