Demand ischemia and MI type 2 codes

Good Morning

Can anyone tell me when did Demand Ischemia and MI type 2 codes came into effect?  Was these codes used prior to October 2017?

Thanks for your help!

  • Demand ischemia is coded as I24.8 (Other forms of acute ischemic heart disease) and that is part of the ICD-10-CM code set adopted in 2015.  The code for Type II myocardial infraction, I21.81 was added in 2017.
