R90-R94Primary Range
Abnormal findings on diagnostic imaging and in function studies, without diagnosis
This range includes codes for unspecified findings on imaging studies, such as white matter changes.
Demyelinating diseases of the central nervous system
This range includes codes for specific demyelinating diseases like multiple sclerosis, which can cause white matter changes.
Cerebrovascular diseases
This range includes codes for vascular causes of white matter changes, such as small vessel disease.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| R90.82 | White matter disease, unspecified | Use when imaging shows white matter changes without a known cause. |

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 White Matter Disease
Primary ICD-10-CM Codes for white matter disease
Decision Criteria
clinical Criteria
- MRI shows white matter changes without a known cause.
coding Criteria
- No other specific diagnosis is documented.
Applicable To
- Unspecified white matter changes on imaging
Clinical Validation Requirements
- MRI findings of white matter hyperintensities without a definitive diagnosis
Code-Specific Risks
- Risk of undercoding if a specific diagnosis is known but not documented.
Coding Notes
- Ensure documentation specifies the lack of a definitive diagnosis when using R90.82.
I67.82 - Cerebral ischemia
Use when white matter changes are attributed to vascular causes.
Applicable To
- Small vessel ischemic disease
Excludes
- White matter disease, unspecified (R90.82)
Clinical Validation Requirements
- Documentation of vascular risk factors and imaging findings consistent with ischemia.
Coding Notes
Ensure vascular risk factors are documented when using I67.82.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Differential Codes
Alternative codes to consider when ruling out similar conditions to the primary diagnosis.
Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting White Matter Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code R90.82.
Impact
Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to lack of specificity.
Mitigation Strategy
Use specific neuroradiologic terms., Correlate imaging findings with clinical symptoms.
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use the specific code for the known diagnosis, such as G35 for MS.
Impact
High risk of audit if R90.82 is used without clear documentation.
Mitigation Strategy
Ensure thorough documentation of imaging findings and clinical correlation.
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.
