Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction
Chapter 9:Diseases of the circulatory system
ICD-10 I22 is a used to indicate a diagnosis of subsequent st elevation (stemi) and non-st elevation (nstemi) myocardial infarction.
I22 codes are used to classify subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarctions, which are critical cardiovascular events characterized by the interruption of blood supply to the heart muscle. The clinical presentation often includes chest pain, shortness of breath, and other symptoms indicative of acute coronary syndrome. The anatomy involved primarily includes the coronary arteries, which supply blood to the heart. Disease progression can lead to complications such as heart failure, arrhythmias, or even sudden cardiac death if not managed promptly. Diagnostic considerations for I22 include a thorough patient history, physical examination, and diagnostic tests such as ECG, cardiac biomarkers, and imaging studies to confirm the diagnosis and assess the extent of myocardial damage. Accurate coding is essential for appropriate treatment planning and reimbursement, as well as for tracking the incidence and outcomes of myocardial infarctions in the population.

I22 codes cover subsequent myocardial infarctions that occur after an initial event, including both STEMI and NSTEMI types. These codes are used when a patient has a new myocardial infarction following a previous one, indicating the need for careful monitoring and management.
I22 should be used when a patient presents with a subsequent myocardial infarction after an initial event has been documented. It is crucial to differentiate between initial and subsequent events to ensure accurate coding and appropriate treatment.
Documentation for I22 should include a detailed patient history, evidence of previous myocardial infarction, current clinical findings, and results from diagnostic tests that confirm the occurrence of a subsequent myocardial infarction.
