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

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Functional Neurological Disorder
Primary ICD-10-CM Codes for functional neurological disorder
Decision Criteria
clinical Criteria
- Presence of motor symptoms that are inconsistent with known neurological patterns.
Applicable To
- Functional movement disorders
- Psychogenic tremor
Excludes
- Organic movement disorders
Clinical Validation Requirements
- Inconsistency between exam findings and organic patterns
- Video evidence of incongruent movements
Code-Specific Risks
- Misclassification as an organic disorder
- Lack of video documentation
Coding Notes
- Ensure documentation includes specific motor symptoms and their inconsistency with known neurological diseases.
F44.5 - Conversion disorder with seizures or convulsions
Use when seizures are documented without epileptiform activity on EEG.
Applicable To
- Functional seizures
- Psychogenic non-epileptic seizures (PNES)
Excludes
- Epileptic seizures
Clinical Validation Requirements
- Events lack epileptiform correlate on video-EEG monitoring
- Preserved awareness during 'unconscious' episodes
Coding Notes
Ensure EEG results are documented to confirm the absence of epileptiform activity.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Functional Neurological Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code F44.4.
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 Strategy
Use structured templates for documentation., Include specific clinical findings and diagnostic tests.
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 Strategy
Confirm with video-EEG and document findings to use F44.5 appropriately.
Impact
Coding functional seizures as epilepsy without EEG confirmation.
Mitigation Strategy
Require video-EEG confirmation for all suspected functional seizures.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
