Frequently Asked Questions
What is ICD-10 code I22?
ICD-10-CM code I22 represents "Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction". It is a non-billable header code — use a more specific child code for billing purposes.
Is I22 a billable code?
No, I22 is a non-billable header code. You need to use one of its more specific child codes for billing. There are 5 child codes under I22.
