Subsequent ST elevation (STEMI) myocardial infarction of inferior wall
ICD-10 I22.1 is a billable code used to indicate a diagnosis of subsequent st elevation (stemi) myocardial infarction of inferior wall.
I22.1 refers to a subsequent ST elevation myocardial infarction (STEMI) affecting the inferior wall of the heart. This condition typically arises when there is a re-occlusion of a coronary artery that has previously been treated, leading to renewed ischemia and myocardial damage. The inferior wall is primarily supplied by the right coronary artery (RCA) in right-dominant coronary systems, and ischemia in this area can result in specific clinical presentations such as chest pain, shortness of breath, and potential complications like heart failure or arrhythmias. The progression of this condition can vary; some patients may experience mild symptoms while others may face severe complications. Diagnostic considerations include electrocardiograms (ECGs) showing ST-segment elevation in the inferior leads (II, III, aVF), elevated cardiac biomarkers, and imaging studies to assess myocardial viability. Prompt recognition and treatment are crucial to minimize myocardial damage and improve outcomes.

I22.1 covers subsequent ST elevation myocardial infarction of the inferior wall, specifically indicating a re-occlusion of the coronary artery leading to renewed ischemia after a previous STEMI.
I22.1 should be used when there is clear documentation of a subsequent STEMI affecting the inferior wall, as opposed to initial events or other types of myocardial infarctions.
Documentation should include ECG findings showing ST elevation in the inferior leads, elevated cardiac enzymes, and a clear history of prior myocardial infarction.
