Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Ischemic heart diseases
      (I20-I25)
      • Subsequent ST elevation and non-ST elevation (NSTEMI) myocardial infarction (I22)
        (STEMI)

I22 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of subsequent st elevation (stemi) and non-st elevation (nstemi) myocardial infarction. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Subsequent STEMI & NSTEMI mocard infrc

Non-specific codes like I22 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for subsequent stemi & nstemi mocard infrc:

  • Use I22.0 for Subsequent ST elevation (STEMI) myocardial infarction of anterior wall - BILLABLE CODE

  • Use I22.1 for Subsequent ST elevation (STEMI) myocardial infarction of inferior wall - BILLABLE CODE

  • Use I22.2 for Subsequent non-ST elevation (NSTEMI) myocardial infarction - BILLABLE CODE

  • Use I22.8 for Subsequent ST elevation (STEMI) myocardial infarction of other sites - BILLABLE CODE

  • Use I22.9 for Subsequent ST elevation (STEMI) myocardial infarction of unspecified site - BILLABLE CODE

Tabular List of Diseases and Injuries

The following annotation back-references are applicable to this diagnosis code. The Tabular List of Diseases and Injuries is a list of ICD-10-CM codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more.


Includes

Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
  • acute myocardial infarction occurring within four weeks (28 days) of a previous acute myocardial infarction, regardless of site
  • cardiac infarction
  • coronary (artery) embolism
  • coronary (artery) occlusion
  • coronary (artery) rupture
  • 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

Use Additional Code

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
  • code, if applicable, to identify:
  • exposure to environmental tobacco smoke Z77.22
  • history of tobacco dependence Z87.891
  • occupational exposure to environmental tobacco smoke Z57.31
  • status post administration of tPA rtPA in a different facility within the last 24 hours prior to admission to current facility Z92.82
  • tobacco dependence F17
  • tobacco use Z72.0

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • subsequent myocardial infarction, type 2 I21.A1
  • subsequent myocardial infarction of other type type 3 type 4 type 5 I21.A9

Patient Education


Heart Attack

Each year almost 800,000 Americans have a heart attack. A heart attack happens when blood flow to the heart suddenly becomes blocked. Without the blood coming in, the heart can't get oxygen. If not treated quickly, the heart muscle begins to die. But if you do get quick treatment, you may be able to prevent or limit damage to the heart muscle. That's why it's important to know the symptoms of a heart attack and call 911 if you or someone else is having them. You should call, even if you are not sure that it is a heart attack.

The most common symptoms in men and women are:

  • Chest discomfort. It is often in center or left side of the chest. It usually lasts more than a few minutes. It may go away and come back. It can feel like pressure, squeezing, fullness, or pain. It also can feel like heartburn or indigestion.
  • Shortness of breath. Sometimes this is your only symptom. You may get it before or during the chest discomfort. It can happen when you are resting or doing a little bit of physical activity.
  • Discomfort in the upper body. You may feel pain or discomfort in one or both arms, the back, shoulders, neck, jaw, or upper part of the stomach.

You may also have other symptoms, such as nausea, vomiting, dizziness, and lightheadedness. You may break out in a cold sweat. Sometimes women will have different symptoms then men. For example, they are more likely to feel tired for no reason.

The most common cause of heart attacks is coronary artery disease (CAD). With CAD, there is a buildup of cholesterol and other material, called plaque, on their inner walls or the arteries. This is atherosclerosis. It can build up for years. Eventually an area of plaque can rupture (break open). A blood clot can form around the plaque and block the artery.

A less common cause of heart attack is a severe spasm (tightening) of a coronary artery. The spasm cuts off blood flow through the artery.

At the hospital, health care providers make a diagnosis based on your symptoms, blood tests, and different heart health tests. Treatments may include medicines and medical procedures such as coronary angioplasty. After a heart attack, cardiac rehabilitation and lifestyle changes can help you recover.
