There is a distinct ICD 10 code for a Type 2 MI (I21.A1). The code for Type 2 MI (I21.A1) will be assigned with the following documentation:
-Type 2 MI
-Myocardial Infarction (MI) due to Demand Ischemia
-Myocardial Infarction (MI) secondary to ischemic imbalance

*Note Type 2 “Event” does not code to Type 2 MI and a query is recommended for clarification.

To diagnose a Type 2 MI

Acute Myocardial Injury as evidenced by an abnormal troponin with a rise/fall

AND

Evidence of imbalance between myocardial oxygen supply and demand with acute myocardial ischemia unrelated to coronary thrombosis as evidenced by ONE of the
following:

-Symptoms of myocardial ischemia (chest pain, shortness of breath, etc.)
-New ischemic ECG changes
-Development of pathological Q waves
-Imaging evidence of new loss of viable myocardium or new regional wall motion abnormality in a pattern consistent with an ischemic etiology
