What is the ICD-10 code for transverse myelitis?

The ICD-10 code for transverse myelitis associated with demyelinating diseases is G37.3. For idiopathic or post-infectious cases, use G04.8.

How do you code transverse myelitis in neuromyelitis optica?

For transverse myelitis in neuromyelitis optica, use the ICD-10 code G36.0, especially if AQP4-IgG is positive.

Compare key differences between these codes to ensure accurate selection

Code	Description	When to Use	Key Documentation
G37.3	Acute transverse myelitis in demyelinating disease of central nervous system	Use when transverse myelitis is part of a demyelinating disease such as multiple sclerosis.	MRI showing focal demyelinating lesion less than 3 vertebral segments CSF pleocytosis (5-50 WBC/mm³)
G04.8	Other specified encephalitis, myelitis, and encephalomyelitis	Use for idiopathic or post-infectious transverse myelitis not associated with demyelinating diseases.	Post-viral onset negative AQP4-IgG MRI findings not consistent with demyelinating disease
G36.0	Neuromyelitis optica [Devic]	Use when transverse myelitis is part of neuromyelitis optica spectrum disorder.	MRI showing lesion ≥3 vertebral segments Positive AQP4-IgG serology

Documentation & Coding Risks

Avoid these common issues when documenting Transverse Myelitis.

Omitting serology results in documentation.

Impact

Clinical: May lead to incorrect diagnosis and treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.

Mitigation

Ensure all relevant serology tests are documented., Review documentation before submission.

Using G37.3 for post-viral transverse myelitis.

Impact

Reimbursement: Incorrect coding may lead to reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.

Mitigation

Use G04.8 for post-viral cases.

Incorrect code selection

Impact

Using G37.3 for non-demyelinating cases.

Mitigation

Implement regular training on code differentiation.
