The 2022 edition of ICD-10-CM I21.3 became effective on October 1, 2021. This is the American ICD-10-CM version of I21.3 - other international versions of ICD-10 I21.3 may differ. transient cerebral ischemic attacks and related syndromes ( G45.-)
Acute myocardial infarction (ICD-9/ICD-9-CM: 410; or ICD-10-CA: I21, I22)
Type 1 MI (STEMI, NSTEMI) Patients having a Type 1 MI should exhibit symptoms of ischemia (chest pain or other angina equivalent) and/or evidence of ischemia on electrocardiography, echocardiography, or stress testing. The diagnosis is usually confirmed by coronary angiography. STEMI (codes I21. 01-I21.
The ECG is the “gold standard” technique for diagnosis of cardiac ar- rhythmias, conduction disturbances, preexcitation, acute coronary syndromes, and chronic myocardial infarction with Q waves.

If only type 1 STEMI or transmural MI without the site is documented, code I21. 3 should be assigned. NSTEMI code I21. 4 should be reported for type 1 non ST elevation myocardial infarction (NSTEMI) and nontransmural MIs.
Type 1. Type 1 MI is due to acute coronary atherothrombotic myocardial injury with either plaque rupture or erosion and, often, associated thrombosis. Most patients with ST-segment elevation MI (STEMI) and many with non-ST-segment elevation MI (NSTEMI) fit into this category.
Background: The admission ECG is the cornerstone in the diagnosis of AMI, and ceMRI is a new diagnostic gold standard that can be used to validate existing and novel 12-lead ECG criteria. Methods: One hundred fifty-one consecutive patients with their first hospital admission for chest pain underwent ceMRI.
Troponin I is a cardiac and skeletal muscle protein family. It is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Troponin I prevents myosin from binding to actin in relaxed muscle.
The ST segment encompasses the region between the end of ventricular depolarization and beginning of ventricular repolarization on the ECG. In other words, it corresponds to the area from the end of the QRS complex to the beginning of the T wave.
BA41. Z Acute myocardial infarction, unspecified - ICD-11 MMS.
An acute MI should be reported for up to 4 weeks (28 days) with a code from category I21. Encounters for care related to the MI after the 4‐week timeframe should be coded with the appropriate aftercare code. An old or healed MI, not requiring further care, should be coded as I25. 2, Old Myocardial Infarction.
