ICD-10 code I21. 9 for Acute myocardial infarction, unspecified is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
BA41. Z Acute myocardial infarction, unspecified - ICD-11 MMS.
ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.
Last October, the code I21. A1, Myocardial infarction, Type 2, was added to ICD-10-CM.
Type 2 MI is the most common type of MI encountered in clinical settings in which is there is demand-supply mismatch resulting in myocardial ischemia. This demand supply mismatch can be due to multiple reasons including but not limited to presence of a fixed stable coronary obstruction, tachycardia, hypoxia or stress.

Type 1 MI is a primary coronary arterial event attributable to atherothrombotic plaque rupture or erosion. Type 2 MI occurs secondary to an acute imbalance in myocardial oxygen supply and demand without atherothrombosis.
Type 2 myocardial infarction (MI) is defined by a rise and fall of cardiac biomarkers and evidence of ischemia without unstable coronary artery disease (CAD), due to a mismatch in myocardial oxygen supply and demand. Myocardial injury is similar but does not meet clinical criteria for MI.
(NSTEMI) is a common diagnosis in hospitalized patients. Type 2 has been reported up to 25% of cases of MI depending on the population studied. Type 2 NSTEMI is defined as myocardial ischemia resulting from mismatched myocardial oxygen supply and demand that is not related to unstable coronary artery disease (CAD).
Patients who present with abdominal discomfort and shortness of breath may have their cardiac troponin level measured, which, if combined with other features such as ischemic ECG changes and symptoms, may lead to a type 2 MI diagnosis.
