ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction
I21 is not a billable ICD-10-CM diagnosis code and cannot be used to indicate a medical diagnosis as there are 2 codes below I21 that describe this diagnosis in greater detail.
Reimbursement claims with a date of service on or after October 1, 2015 require the use of ICD-10-CM codes.

discomfort in the upper body - arms, shoulder, neck, back
these symptoms can sometimes be different in women.what exactly is a heart attack? most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart. A blockage that is not treated within a few hours causes the affected heart muscle to die.
Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area, as in coronary thrombosis.
Gross necrosis of the myocardium, as a result of interruption of the blood supply to the area.
Necrosis of the myocardium caused by an obstruction of the blood supply to the heart (coronary circulation).
