READER QUESTIONS:

Look to 414.8 for History of MI

Question: Our new patient has coronary artery disease (CAD), ischemic cardiomyopathy, and history of myocardial infarction (MI). How should I code for him?

-- Mississippi Subscriber

Answer: If the patient has never had a coronary artery bypass graft (CABG), the code to list for CAD is 414.01 (Coronary atherosclerosis of native coronary artery). For ischemic cardiopathy, list 414.8 (Other specified forms of chronic ischemic heart disease).

Listing 414.8 for the ischemic cardiopathy also covers the history of MI. If you read the notes under this code, you'll see that 414.8 is used to indicate "any condition classifiable to 410 (Acute myocardial infarction) specified as chronic, or presenting with symptoms after eight weeks from date of infarction."
