What is the ICD-10 code for functional neurological disorder?

The ICD-10 code for functional neurological disorder, specifically for conversion disorder with seizures, is F44.5.

How is functional neurological disorder diagnosed?

Functional neurological disorder is diagnosed through clinical evaluation, including video-EEG to confirm the absence of epileptiform activity.

Code Comparison: When to Use Each Code

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
F44.4	Conversion disorder with motor symptom or deficit	Use when there is a documented inconsistency in motor symptoms that do not align with organic disease patterns.	Inconsistency between exam findings and organic patterns Video evidence of incongruent movements
F44.5	Conversion disorder with seizures or convulsions	Use when seizures are documented without epileptiform activity on EEG.	Events lack epileptiform correlate on video-EEG monitoring Preserved awareness during 'unconscious' episodes

Documentation & Coding Risks

Avoid these common issues when documenting Functional Neurological Disorder.

Lack of specific symptom documentation

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Increases risk of audit failure., Financial: Potential for denied claims due to insufficient documentation.

Mitigation

Use structured templates for documentation., Include specific clinical findings and diagnostic tests.

Using R56.9 for functional seizures without further investigation

Impact

Reimbursement: May result in lower reimbursement if not coded correctly., Compliance: Increases risk of audit failure due to incorrect coding., Data Quality: Leads to inaccurate data on seizure prevalence.

Mitigation

Confirm with video-EEG and document findings to use F44.5 appropriately.

Incorrect coding of functional seizures

Impact

Coding functional seizures as epilepsy without EEG confirmation.

Mitigation

Require video-EEG confirmation for all suspected functional seizures.
