| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I67.2 | Cerebral atherosclerosis | Use when cerebral atherosclerosis is present without acute infarction. |
|
| I63.511 | Cerebral infarction due to embolism of right middle cerebral artery | Use when an embolic infarction of the right MCA is confirmed. |

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 cerebrovascular atherosclerosis
Decision Criteria
clinical Criteria
- Presence of cerebral atherosclerosis without infarction
coding Criteria
- Excludes1 note prohibits use with I63.- codes
Applicable To
- Asymptomatic cerebral atherosclerosis
Excludes
- Cerebral infarction (I63.-)
Clinical Validation Requirements
- MRA showing <50% stenosis
- Carotid ultrasound with intima-media thickness ≥1.5mm without flow-limiting stenosis
Code-Specific Risks
- Incorrectly used with infarction codes due to Excludes1 note.
Coding Notes
- Ensure documentation specifies no acute infarction when using I67.2.
I63.511 - Cerebral infarction due to embolism of right middle cerebral artery
Use when an embolic infarction of the right MCA is confirmed.
Excludes
- Cerebral atherosclerosis (I67.2)
Clinical Validation Requirements
- MRI DWI showing acute infarction
- MRA/CTA confirming corresponding artery stenosis ≥50%
Coding Notes
Sequence correctly with occlusion codes for accurate DRG assignment.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.
Occlusion and stenosis of precerebral arteries
I65.-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 Cerebrovascular Atherosclerosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I67.2.
Impact
Clinical: Inaccurate clinical picture of the stroke., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims or incorrect reimbursement.
Mitigation Strategy
Specify artery involvement in documentation., Use precise medical terminology.
Impact
Reimbursement: Incorrect DRG assignment can affect reimbursement., Compliance: Non-compliance with Excludes1 note., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Query provider to specify the artery involved.
Impact
High audit risk if artery involvement is not documented.
Mitigation Strategy
Ensure detailed documentation of the specific artery involved in the stroke.
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.
