| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G51.3 | Clonic hemifacial spasm | Use when hemifacial spasm is confirmed with clinical and imaging evidence. |
|
| G51.31 | Right clonic hemifacial spasm | Use when laterality is confirmed as right-sided. |
|
| G51.32 | Left clonic hemifacial spasm | Use when laterality is confirmed as left-sided. |
|
| G51.4 | Facial myokymia | Use when continuous rippling movements are confirmed by EMG. |

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 Facial Twitching
Primary ICD-10-CM Codes for facial twitching
Decision Criteria
clinical Criteria
- Presence of unilateral facial twitching with spread pattern
coding Criteria
- Documented MRI evidence of neurovascular compression
Applicable To
- Unilateral facial muscle spasms
Excludes
- Blepharospasm (G24.5)
Clinical Validation Requirements
- Unilateral spread pattern
- MRI/MRA showing vascular compression
Code-Specific Risks
- Misclassification with blepharospasm
Coding Notes
- Ensure laterality is documented to avoid unspecified coding.
G51.31 - Right clonic hemifacial spasm
Use when laterality is confirmed as right-sided.
Applicable To
- Right-sided facial muscle spasms
Clinical Validation Requirements
- Right-sided facial twitching confirmed by clinical exam
Coding Notes
Ensure right laterality is clearly documented.
G51.32 - Left clonic hemifacial spasm
Use when laterality is confirmed as left-sided.
Applicable To
- Left-sided facial muscle spasms
Clinical Validation Requirements
- Left-sided facial twitching confirmed by clinical exam
Coding Notes
Ensure left laterality is clearly documented.
G51.4 - Facial myokymia
Use when continuous rippling movements are confirmed by EMG.
Applicable To
- Continuous undulating facial muscle movements
Clinical Validation Requirements
- EMG confirms myokymic discharges
Coding Notes
Ensure EMG findings are documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

G51.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Facial Twitching to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G51.3.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with ICD-10 coding standards., Financial: Potential for denied claims or reduced reimbursement.
Mitigation Strategy
Always specify right or left in clinical documentation.
Impact
Reimbursement: May lead to reduced reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of clinical data.
Mitigation Strategy
Always specify laterality using G51.31 or G51.32.
Impact
Failure to document laterality can lead to audit flags.
Mitigation Strategy
Implement mandatory fields for laterality in EHR templates.
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.
