Acute myocardial infarction (ICD-9/ICD-9-CM: 410; or ICD-10-CA: I21, I22)
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops to the coronary artery of the heart, causing damage to the heart muscle....Myocardial infarctionOther namesAcute myocardial infarction (AMI), heart attack12 more rows
What is a “subsequent” myocardial infarction? An Inclusion note in the Tabular, category I22 Subsequent ST elevation (STEMI) and non-STE explains that it is an “acute myocardial infarction occurring within four weeks (28 days) of a previous acute myocardial infarction, regardless of site.”
Acute myocardial infarction, unspecified I21. 9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I21. 9 became effective on October 1, 2021.
BA41. Z Acute myocardial infarction, unspecified - ICD-11 MMS.
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.
post-MI pericarditis (back to contents) Also known as Dressler's Syndrome, or post-cardiac injury syndrome (although these terms include other causes such as post-CABG pericarditis). This may solely include pericarditis, or it may involve a combination of pericarditis plus pleural effusions (pleuropericarditis).
ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.

A code from category I22, Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction, is to be used when a patient who has suffered a type 1 or unspecified AMI has a new AMI within the 4-week time frame of the initial AMI.
