ST elevation (STEMI) myocardial infarction of other sites
ICD-10 I21.2 is a used to indicate a diagnosis of st elevation (stemi) myocardial infarction of other sites.
I21.2 refers to ST elevation myocardial infarction (STEMI) occurring in sites other than the anterior wall, inferior wall, or lateral wall of the heart. This condition is characterized by the elevation of the ST segment on an electrocardiogram (ECG), indicating significant myocardial injury due to prolonged ischemia. The clinical presentation often includes chest pain, shortness of breath, and other symptoms of acute coronary syndrome. The anatomy involved primarily includes the coronary arteries that supply blood to the heart muscle, and the specific site of infarction can vary, affecting different regions of the myocardium. Disease progression can lead to complications such as heart failure, arrhythmias, or cardiogenic shock if not promptly treated. Diagnostic considerations include ECG findings, cardiac biomarkers (like troponin levels), and imaging studies such as echocardiography or coronary angiography to assess the extent of myocardial damage and identify the occluded coronary artery. Prompt recognition and treatment are crucial to improve outcomes in patients with STEMI.

I21.2 covers ST elevation myocardial infarction occurring in sites other than the anterior, inferior, or lateral walls, which may include posterior or right ventricular myocardial infarctions. It is essential to confirm the site of infarction through diagnostic imaging and ECG findings.
I21.2 should be used when the myocardial infarction is confirmed to be ST elevation and occurs in a site not classified under I21.0 or I21.1. Accurate ECG interpretation and clinical correlation are necessary to differentiate between these codes.
Documentation must include a detailed account of the patient's symptoms, ECG findings showing ST elevation, cardiac biomarker results, and any imaging studies performed. Clear notes on the site of infarction and treatment provided are also crucial.
