| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G37.8 | Other specified demyelinating diseases of central nervous system | Use when a specific demyelinating disease is identified, such as MOGAD. |
|
| G37.9 | Demyelinating disease of central nervous system, unspecified | Use when the specific type of demyelinating disease cannot be determined. |

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

Primary ICD-10-CM Codes for demyelinating disease
Decision Criteria
clinical Criteria
- Positive MOG-IgG1 antibody test
Applicable To
- MOG antibody disease
- Baló's concentric sclerosis
Clinical Validation Requirements
- Positive MOG-IgG1 via live cell-based assay
- Clinical phenotype such as optic neuritis
Code-Specific Risks
- Misclassification if specific disease is not documented
Coding Notes
- Ensure specific disease is documented to avoid using unspecified codes.
G37.9 - Demyelinating disease of central nervous system, unspecified
Use when the specific type of demyelinating disease cannot be determined.
Excludes
- Multiple sclerosis (G35)
- Neuromyelitis optica (G36.0)
Clinical Validation Requirements
- General symptoms of demyelination without specific diagnosis
Coding Notes
Use only when specific disease type is not documented.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

R29.818Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Demyelinating Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G37.8.
Impact
Clinical: Misdiagnosis or delayed diagnosis, Regulatory: Non-compliance with coding guidelines, Financial: Potential for denied claims
Mitigation Strategy
Ensure all test results are documented, Use templates to guide documentation
Impact
Reimbursement: May result in lower reimbursement due to unspecified coding, Compliance: Non-compliance with specificity requirements, Data Quality: Decreased accuracy in patient records
Mitigation Strategy
Query provider for test results to specify diagnosis
Impact
High frequency of G37.9 usage without specific tests
Mitigation Strategy
Encourage specific testing and documentation
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.
