ST elevation (STEMI) myocardial infarction involving left main coronary artery
ICD-10 I21.01 is a billable code used to indicate a diagnosis of st elevation (stemi) myocardial infarction involving left main coronary artery.
I21.01 refers to ST elevation myocardial infarction (STEMI) specifically involving the left main coronary artery. This condition is characterized by the sudden blockage of blood flow to the heart muscle due to a thrombus (blood clot) that forms in the left main coronary artery, which supplies a significant portion of the heart's blood supply. Clinically, patients may present with severe chest pain, shortness of breath, and other symptoms of acute coronary syndrome. The left main coronary artery is critical as it branches into the left anterior descending artery and the left circumflex artery, affecting a large area of the myocardium. Disease progression can lead to extensive myocardial damage and increased risk of complications such as heart failure or arrhythmias. Diagnostic considerations include electrocardiogram (ECG) changes showing ST elevation, elevated cardiac biomarkers, and imaging studies like coronary angiography to confirm the blockage. Prompt recognition and treatment are vital to restore blood flow and minimize heart damage.

I21.01 covers ST elevation myocardial infarction specifically involving the left main coronary artery, which can lead to significant myocardial ischemia and requires immediate medical intervention.
I21.01 should be used when the clinical presentation and diagnostic findings confirm an ST elevation myocardial infarction specifically involving the left main coronary artery, differentiating it from other types of myocardial infarctions.
Documentation should include clinical presentation details, ECG findings showing ST elevation, results from cardiac biomarker tests, and any imaging studies that confirm the diagnosis of STEMI involving the left main coronary artery.
