Additional Info

Includes

• supply Demand ischemia
• Ischemia co-occurrent and due to increased oxygen demand (Type 2 MI)
• Subendocardial ischemia
• Coronary artery spasm (coronary vasospasm)
• Stunned myocardium-transient reversible myocardial contractile dysfunction induced by acute ischemia

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 (STEMI), acute (AMI), transmural (Q-wave)
  • Myocardial infarction (NSTEMI), 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

MI - acute vs past history

To decide whether to code an acute MI dx in the Admit Diagnosis or Acquired Diagnosis / Complication, or a Past history, myocardial infarction (old MI) in the Comorbid Diagnosis, consider the following:

• Regarding an MI that occured prior to the current hospitalization -- might be coded as either Comorbid Diagnosis, or a Past history, myocardial infarction (old MI)
• In ICD10 the code for Past history, myocardial infarction (old MI) reads as follows: Healed myocardial infarction -- Past myocardial infarction diagnosed by ECG or other special investigation, but currently presenting no symptoms.
• If the prior MI is still active and we're not dealing with any current complications of it, then instead use one of the AMI codes, as a Comorbid Diagnosis.
• If the prior MI is still active and we are dealing with any current complications of it, then instead use one of the AMI codes, as a Admit Diagnosis.
  • Examples: Papillary muscle rupture or Ongoing angina related to a recent MI prior to this unit/ward admission.
• For a missed MI: code it as one of the "...acute..." codes if the missed MI is being treated as an acute MI
