Primary ICD-10-CM Code for trigeminal neuralgia
Decision Criteria
clinical Criteria
- Presence of paroxysmal facial pain triggered by innocuous stimuli
documentation Criteria
- MRI findings of neurovascular compression
Applicable To
- Classic trigeminal neuralgia
- Idiopathic trigeminal neuralgia
Clinical Validation Requirements
- Sudden, severe, electric-shock-like facial pain
- Pain triggered by stimuli such as chewing or wind
- MRI showing neurovascular compression
Code-Specific Risks
- Incorrectly coding symptomatic TN without underlying condition
- Omitting laterality in documentation
Coding Notes
- Ensure documentation specifies classic vs. symptomatic TN and includes laterality.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Personal history of other diseases of the nervous system
Z86.69Differential Codes

G50.1Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Trigeminal Neuralgia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G50.0.
Impact
Clinical: Inaccurate representation of condition severity, Regulatory: Potential for audit issues, Financial: Possible claim denials or delays
Mitigation Strategy
Always document affected side, Use standardized templates
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use B02.22 for postherpetic trigeminal neuralgia.
Impact
Lack of MRI evidence in clinical notes can lead to audit issues.
Mitigation Strategy
Ensure MRI findings are documented in patient records.
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.
