ST elevation (STEMI) myocardial infarction involving left anterior descending coronary artery
ICD-10 I21.02 is a billable code used to indicate a diagnosis of st elevation (stemi) myocardial infarction involving left anterior descending coronary artery.
I21.02 refers to ST elevation myocardial infarction (STEMI) specifically involving the left anterior descending (LAD) coronary artery. This condition is characterized by the acute blockage of the LAD artery, which supplies blood to the anterior wall of the left ventricle. Clinically, patients may present with severe chest pain, shortness of breath, and diaphoresis. The LAD artery is crucial as it supplies a significant portion of the heart muscle, and its occlusion can lead to extensive myocardial damage. Disease progression can result in complications such as heart failure, arrhythmias, or cardiogenic shock if not promptly treated. Diagnostic considerations include the use of electrocardiograms (ECGs) to identify ST elevation, along with cardiac biomarkers to confirm myocardial injury. Timely intervention, typically via percutaneous coronary intervention (PCI) or thrombolytic therapy, is critical to restore blood flow and minimize heart muscle damage.

I21.02 covers ST elevation myocardial infarction specifically involving the left anterior descending coronary artery, characterized by ST segment elevation on ECG and elevated cardiac biomarkers indicating myocardial necrosis.
I21.02 should be used when the clinical scenario indicates an ST elevation myocardial infarction involving the LAD artery, as opposed to other coronary arteries, which would require different codes such as I21.01 or I21.09.
Documentation should include clinical findings such as ECG results showing ST elevation, patient symptoms, and laboratory results indicating elevated troponin levels or other cardiac markers.
