Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction - I22
This notation helps users understand the scope of a code I22 category and provides additional information about the conditions or terms that fall under that category.
Category Includes:
- 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: This note indicates that an additional code should be used in conjunction with the primary code "I22" to provide a complete picture of the patient's condition or to capture associated factors.
Use Additional:
- 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)
Excludes1: It indicates that the conditions described by two codes cannot occur together in the same patient. These codes are mutually exclusive.
Type 1 Excludes:
- subsequent myocardial infarction, type 2 (I21.A1)
- subsequent myocardial infarction of other type (type 3) (type 4) (type 5) (I21.A9)
These ranges represents subcategories of Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction. The "I22" signifies that these are the diseases within this broad category.
Codes:
- I22.0 - Subsequent ST elevation (STEMI) myocardial infarction of anterior wall
- I22.1 - Subsequent ST elevation (STEMI) myocardial infarction of inferior wall
- I22.2 - Subsequent non-ST elevation (NSTEMI) myocardial infarction
- I22.8 - Subsequent ST elevation (STEMI) myocardial infarction of other sites
- I22.9 - Subsequent ST elevation (STEMI) myocardial infarction of unspecified site
