How do I code NSTEMI Type 2?
When If a type 2 AMI code is described as NSTEMI or STEMI, only assign code I21. A1. Codes I21.
What is a Type II NSTEMI?
Type 2 NSTEMI is defined as myocardial ischemia resulting from mismatched myocardial oxygen supply and demand that is not related to unstable coronary artery disease (CAD).
Is NSTEMI a Type 2 MI?
Most NSTEMI (65%-90%) are type 1 MI. Patients with type 2 MI have multiple comorbidities and causes of in-hospital mortality among these patients are not always CV-related.
Is type 2 MI stemi or NSTEMI?
Figure 1: Classification of MI
| MI Type | Classification |
|---|---|
| 1 | STEMI (acute coronary artery thrombosis) NSTEMI (acute coronary artery plaque rupture/erosion) |
| 2 | Supply/demand mismatch (heterogeneous underlying causes) |
| 3 | Sudden cardiac death with ECG evidence of acute myocardial ischemia before cardiac troponins could be drawn |
When do you code NSTEMI?
A code from category I22, Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction, is to be used when a patient who has suffered a type 1 or unspecified AMI has a new AMI within the 4-week time frame of the initial AMI.
How do I code NSTEMI?
ICD-10-CM Code for Non-ST elevation (NSTEMI) myocardial infarction I21. 4.
What is the difference between Type 1 and Type 2 NSTEMI?
For patients with type 1 MI, the focus is on aggressive antithrombotic therapy and consideration of urgent coronary angiography and revascularization. For patients with type 2 MI, the focus is on treating the extracardiac stressor precipitating the myocardial oxygen supply and demand imbalance.
How do you code a STEMI and NSTEMI?
STEMI (codes I21. 01-I21. 3) documentation should indicate the underlying etiology of acute coronary thrombus as well as location and artery involved. Equally, a NSTEMI (code I21.
What is Type 1 and Type 2 MI?
Type 1 MI is a primary coronary arterial event attributable to atherothrombotic plaque rupture or erosion. Type 2 MI occurs secondary to an acute imbalance in myocardial oxygen supply and demand without atherothrombosis.
Is Type 1 or Type 2 MI worse?
The one-year mortality rate was significantly higher for type 2 MI: 27% of these patients died at the end of one year compared to 13% of type 1 patients (P<0.00001) (Figure 5).
