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. |
|
| F44.5 | Conversion disorder with seizures or convulsions | Use when seizures are documented without epileptiform activity on EEG. |

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.
