| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I23.6 | Thrombosis of atrium, auricular appendage, and ventricle as current complications following acute myocardial infarction | Use when LV thrombus is a complication within 4 weeks of an acute MI. |
|
| I51.3 | Intracardiac thrombus, not elsewhere classified | Use for chronic thrombus or when unrelated to recent MI. |

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
- Thrombus confirmed by imaging within 4 weeks of MI
Applicable To
- Acute thrombus post-MI

Use for chronic thrombus or when unrelated to recent MI.
Applicable To
- Chronic intracardiac thrombus
Excludes
- Acute thrombus post-MI (I23.6)
Clinical Validation Requirements
- Imaging confirming chronic thrombus
- No recent MI
Coding Notes
Ensure chronicity is documented if using this code.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Left Ventricular Thrombus to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I23.6.
Impact
Clinical: Misrepresentation of patient condition, Regulatory: Potential audit issues, Financial: Incorrect DRG assignment
Mitigation Strategy
Always document MI and thrombus dates, Use templates to ensure completeness
Impact
Reimbursement: Incorrect DRG assignment, Compliance: Non-compliance with ICD-10 guidelines, Data Quality: Inaccurate clinical data representation
Mitigation Strategy
Use I23.6 for thrombus within 4 weeks of MI.
Impact
Risk of coding thrombus outside the 4-week window as acute
Mitigation Strategy
Verify dates of MI and thrombus diagnosis in documentation
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.
