RMC’s AHIMA Approved ICD-10 Trainers meet multiple times per week fielding questions from clients and staff.  Below is an actual question that was submitted, along with our team’s response.*

Coding Question:  Can you help with coding “Silent MI”?  Would this be considered I21.9-myocardial infarction, unsp; or to I25.6-Silent myocardial ischemia?

I forgot to mention the patient’s vitals on the day of the diagnosis of silent MI:

Troponin  6.68

BNP  10,502

RMC Answer:  The trainers feel that because there is an index entry for silent myocardial ischemia, a query to the provider would be recommended.  This is a great area for CDI to review abbreviations and provider education.  Silent Myocardial Ischemia is a new code in ICD-10, in the past providers used “MI” to indicate Myocardial Infarction.
