ICD-10 Code F44.6 – Conversion disorder with sensory symptom or deficit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F44.6 – Conversion disorder with sensory symptom or deficit
What it is
F44.6 identifies conversion disorder presenting with sensory loss or altered sensation that is not explained by a neurological disease. You use it when the record shows functional sensory symptoms, such as numbness or anesthesia, without an organic cause.
Clinical signs
Clinical features vary; refer to documentation. Common findings include sensory loss, reduced sensation, or unusual sensory patterns that do not match known anatomy or pathology. The diagnosis is made after appropriate evaluation excludes a better medical explanation.
When to use this code
Use F44.6 when the provider documents conversion disorder and the main manifestation is sensory deficit or disturbance. It fits cases where the note clearly links the symptom to a functional neurological presentation. If the chart only says numbness, check documentation for the diagnosis.
Do not use for
Do not use this code for sensory loss caused by stroke, neuropathy, trauma, or other confirmed neurologic disease. It is also not appropriate for vague symptoms without documentation of conversion disorder.
Coding tip
Assign F44.6 only when the provider documents both conversion disorder and sensory symptom or deficit; otherwise, check documentation.
