Additional Info
- May (or may not) be seen on EKG as a pre-existing "Q" wave.
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:
- Code the cause separately, as a Combined ICD10 codes. For example it might be one of the following:
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
