MI - type vs mechanism

MIs are occasionally listed as "Type 2 MIs", ie no evidence of coronary artery disease (CAD). This refers to the mechanism, and the AMI codes include any/all mechanisms (including coronary artery embolism, thrombosis or thromboembolism); said another way, we don't particularly care about the mechanism. They should be coded based on their manifestation.

In ICD10, this will mean:

• Code the appropriate AMI code:
  • Myocardial infarction, acute (AMI), transmural (Q-wave)
  • Myocardial infarction, acute (AMI), subendocardial/non-transmural (non-Q-wave)
  • Myocardial infarction, acute (AMI), NOS
  • Past history, myocardial infarction (old MI)
• Code the cause separately, as a Combined ICD10 codes. For example it might be one of the following:
  • Coronary artery disease, chronic (atherosclerosis, chronic ischemic heart disease)
  • Ischemic heart disease, acute NOS
  • anemia - Category:Anemia
  • hypovolemia - Dehydration (volume depletion, hypovolemia)
  • Bradycardia
