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:

• Either may be used for an MI that occurred prior to the current hospitalization.
• If the prior MI is not active, and we're not dealing with any current complications of it, then use Past history, myocardial infarction (old MI)
• 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.
