| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I51.3 | Intracardiac thrombus, not elsewhere classified | Use when thrombus is confirmed in the atrium and not related to recent AMI. |
|
| I23.6 | Thrombosis of atrium following AMI | Use when thrombus is a complication of a recent AMI. |

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 Atrial Thrombus
Primary ICD-10-CM Codes for atrial thrombus
Decision Criteria
clinical Criteria
- Confirmed thrombus in atrium via imaging
coding Criteria
- Thrombus not related to recent AMI
Applicable To
- Left atrial appendage thrombus unrelated to AMI
Excludes
- Thrombosis of atrium following AMI (I23.6)
Clinical Validation Requirements
- Imaging confirmation of thrombus location and size
- TEE findings with SEC grade ≥3
Code-Specific Risks
- Incorrectly coding historical thrombus as active
Coding Notes
- Ensure documentation specifies current thrombus status and location.
I23.6 - Thrombosis of atrium following AMI
Use when thrombus is a complication of a recent AMI.
Applicable To
- Thrombosis as a complication of AMI
Excludes
- Intracardiac thrombus not related to AMI (I51.3)
Clinical Validation Requirements
- Documentation linking thrombus to recent AMI
Coding Notes
Ensure AMI is documented as the cause of the thrombus.
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 Atrial Thrombus to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I51.3.
Impact
Clinical: Misrepresentation of patient's current condition., Regulatory: Potential audit issues., Financial: Incorrect billing and reimbursement.
Mitigation Strategy
Verify current status of thrombus before coding.
Impact
Reimbursement: Incorrect DRG assignment leading to reimbursement issues., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Use I23.6 if thrombus is related to AMI.
Impact
Risk of incorrect code selection for thrombus related to AMI.
Mitigation Strategy
Ensure thorough documentation review linking thrombus to AMI.
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.
