MI code updates

The list of ICD-10 code updates is extensive and Myocardial Infarctions got a makeover with this year’s revision. Code category I21 has been renamed from “ST elevation and non-ST elevation myocardial infarction” to “Acute myocardial infarction”. Additional specificity options now include type 1, type 2, and other MI types. Providers will need to specify in clinical documentation the type of MI the patient experienced. STEMI codes (I21.0 and I21.1) are now defined as Type 1 MIs. New codes I21.A1 – MI type 2 and I21.A9 – other MI type are also important and notable additions.
