| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I63.0 | Cerebral infarction due to thrombosis of precerebral arteries | Use when imaging confirms thrombosis in precerebral arteries causing cerebral infarction. |
|
| I63.3 | Cerebral infarction due to thrombosis of cerebral arteries | Use when thrombosis is localized to cerebral arteries with confirmed infarction. |

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 ischaemic stroke
Decision Criteria
clinical Criteria
- Presence of acute neurological deficits with imaging confirmation of thrombosis
Applicable To
- Thrombosis of carotid artery
- Thrombosis of vertebral artery
Excludes
- Transient ischemic attack (TIA) (G45.-)
Clinical Validation Requirements
- CT/MRI showing thrombosis in precerebral arteries
- Documented acute neurological deficits
Code-Specific Risks
- Misclassification if imaging is not confirmatory
Coding Notes
- Ensure imaging confirms thrombosis before coding.
I63.3 - Cerebral infarction due to thrombosis of cerebral arteries
Use when thrombosis is localized to cerebral arteries with confirmed infarction.
Applicable To
- Thrombosis of middle cerebral artery
- Thrombosis of anterior cerebral artery
Excludes
- Cerebral embolism (I63.4)
Clinical Validation Requirements
- MRI showing thrombosis in cerebral arteries
- Acute onset of focal neurological symptoms
Coding Notes
Differentiate between thrombosis and embolism based on clinical evidence.
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 Ischaemic Stroke to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I63.0.
Impact
Clinical: Impairs treatment planning and outcomes tracking., Regulatory: Increases risk of non-compliance with coding standards., Financial: May result in incorrect billing and reimbursement.
Mitigation Strategy
Use specific ICD-10 codes based on imaging findings, Train staff on documentation standards
Impact
Reimbursement: May lead to incorrect DRG assignment and reimbursement issues., Compliance: Increases audit risk due to lack of specificity., Data Quality: Affects accuracy of clinical data and outcomes tracking.
Mitigation Strategy
Ensure imaging confirms the type and location of infarction before coding.
Impact
High audit risk when using codes like I63.9 without supporting documentation.
Mitigation Strategy
Require imaging confirmation before coding.
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.
