ST elevation (STEMI) myocardial infarction involving right coronary artery
ICD-10 I21.11 is a billable code used to indicate a diagnosis of st elevation (stemi) myocardial infarction involving right coronary artery.
I21.11 refers to ST elevation myocardial infarction (STEMI) involving the right coronary artery (RCA). This condition is characterized by the acute blockage of blood flow to the heart muscle due to a thrombus in the RCA, leading to myocardial ischemia and necrosis. Clinically, patients may present with chest pain, shortness of breath, diaphoresis, and nausea. The RCA supplies blood to the right atrium, right ventricle, and inferior wall of the left ventricle, making its involvement critical for overall cardiac function. Disease progression can lead to 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, cardiac biomarkers to assess myocardial injury, and imaging studies to evaluate cardiac function. Timely intervention, such as percutaneous coronary intervention (PCI) or thrombolytic therapy, is essential to restore blood flow and minimize myocardial damage.

I21.11 specifically covers ST elevation myocardial infarction due to occlusion of the right coronary artery, characterized by ST segment elevation on ECG and elevated cardiac biomarkers indicating myocardial necrosis.
I21.11 should be used when there is clear documentation of ST elevation myocardial infarction involving the RCA, as opposed to other types of myocardial infarctions or unspecified cases.
Documentation must include ECG findings showing ST elevation, clinical symptoms consistent with myocardial infarction, and laboratory results indicating elevated cardiac enzymes such as troponin.
