Intracardiac thrombosis, not elsewhere classified

This code signifies the presence of a blood clot within the chambers of the heart, which is not a direct consequence of a recent heart attack. These thrombi can form in any cardiac chamber, potentially leading to embolic events if dislodged.

Use this code for documented intracardiac thrombi identified through imaging (e.g., echocardiogram) in patients without a recent acute myocardial infarction. This applies to conditions such as atrial fibrillation with left atrial appendage thrombus, or ventricular thrombi in the setting of cardiomyopathy or other structural heart disease.

• Always review documentation to ensure the thrombosis is not a current complication of an acute myocardial infarction, as this would require a different code.
• Specify the location of the thrombus (e.g., left atrium, right ventricle) if documented, as this may influence treatment and further coding.
• Consider sequencing this code after the underlying cardiac condition that predisposed the patient to thrombus formation.
