2020 ICD-10-CM Diagnosis Code I22

Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction

2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code

• I22 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
• Short description: Subsequent STEMI & NSTEMI mocard infrc
• The 2020 edition of ICD-10-CM I22 became effective on October 1, 2019.
• This is the American ICD-10-CM version of I22 - other international versions of ICD-10 I22 may differ.

• A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
• Coagulation of blood in any of the coronary vessels. The presence of a blood clot (thrombus) often leads to myocardial infarction.
• Complete blockage of blood flow through one of the coronary arteries, usually from coronary atherosclerosis.
• Each year over a million people in the United States Have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include
  • chest discomfort - pressure, squeezing, or pain
  • shortness of breath
  • discomfort in the upper body - arms, shoulder, neck, back
  • nausea, vomiting, dizziness, lightheadedness, sweating
  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).
