Wiki MI without stated duration

[heyerflowers@gmail.com]

The medical record says: "stress test normal during past year with nuclear contrast, with the exception of a small area of inferoapical ischemia" How do I code this?
The guideline says subcatgory 410.9 is the default for the unspecified term acute myocardial infarction. If the record does not document the duration, would I use 410.90? Am I interpreting this correctly?
Thanks.

Where are you coming up with the diagnosis of acute MI from the documentation of infereoapical ischemia?

I would just use 794.39 - abnormal stress test

inferoapical ischemia

okay. so when I go to ischemia, ischemic 459.9, the only subcategory might be heart 414.9, there is nothing for inferoapical ischemia;
so I use 414.9?
