| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I67.82 | Cerebral ischemia due to unspecified occlusion or stenosis of small artery | Use when MRI confirms chronic ischemic changes with lacunar infarcts. |
|
| I68.0 | Cerebral amyloid angiopathy | Use when MRI confirms amyloid-related changes with specific markers. |

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

Decision Criteria
clinical Criteria
- MRI shows chronic ischemic changes with lacunar infarcts
documentation Criteria
- Documented chronic ischemic cerebrovascular disease
Applicable To
- Chronic ischemic cerebrovascular disease
Excludes
- Acute ischemic stroke (I63.9)
Clinical Validation Requirements
- MRI showing ≥3 lacunar infarcts
- Chronic ischemic changes documented
Code-Specific Risks
- Incorrectly using for nonspecific white matter changes
Coding Notes
- Ensure documentation specifies 'chronic ischemic changes' for accurate coding.
I68.0 - Cerebral amyloid angiopathy
Use when MRI confirms amyloid-related changes with specific markers.
Applicable To
- Amyloid-related small vessel disease
Excludes
- Vascular dementia (G31.84)
Clinical Validation Requirements
- MRI with lobar microhemorrhages
- Cortical superficial siderosis
Coding Notes
Ensure MRI findings support amyloid angiopathy diagnosis.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

I11.9Differential 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 Small Vessel Disease to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I67.82.
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
Ensure MRI findings are detailed in reports., Use specific terminology like 'chronic ischemic changes'.
Impact
Reimbursement: Incorrect coding may lead to lower reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data representation in patient records.
Mitigation Strategy
Use I67.82 when chronic ischemic changes are documented.
Impact
Using R90.82 for confirmed ischemic changes can trigger audits.
Mitigation Strategy
Ensure MRI findings are documented and support ischemic diagnosis.
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.
