Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.

A type 1 excludes note is a pure excludes. It means "not coded here". A type 1 excludes note indicates that the code excluded should never be used at the same time as I22. A type 1 excludes note is for used for when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • coronary (artery) thrombosis
  • infarction of heart, myocardium, or ventricle
  • recurrent myocardial infarction
  • reinfarction of myocardium
  • rupture of heart, myocardium, or ventricle
  • subsequent type 1 myocardial infarction
Clinical Information
  • 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).
