Code Description

ICD-10 I51.3 is a billable code used to indicate a diagnosis of intracardiac thrombosis, not elsewhere classified.

Key Diagnostic Point:

Intracardiac thrombosis, not elsewhere classified, refers to the formation of a blood clot within the heart chambers, which can lead to serious complications such as embolism, stroke, or myocardial infarction. This condition may arise from various factors, including atrial fibrillation, heart failure, or recent surgery. Diagnosis is typically made through echocardiography or imaging studies, and treatment may involve anticoagulation therapy or surgical intervention to remove the clot.
