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:
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.
