What ICD-10 Codes Are Used for NSTEMI?
Non-ST segment elevation myocardial infarction (NSTEMI) is a type of heart attack with specific electrocardiogram (EKG) changes. Depending on the episode and related conditions, it is classified under multiple NSTEMI ICD codes.
- I21.4 - Non-ST elevation (NSTEMI) myocardial infarction: This is the primary code for NSTEMI.
- I21.A1 - Myocardial infarction type 2: This can include NSTEMI under certain conditions.
- I21.A9 - Other myocardial infarction type: NSTEMI may be coded here when specific criteria are met.
- I22.1 - Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction of the inferior wall: This is for a second event of NSTEMI.
- I22.2 - Subsequent NSTEMI myocardial infarction of other sites: This is for recurrent NSTEMI impacting other areas of the heart.
- I48.91 - Unspecified atrial fibrillation: This code might be used when NSTEMI is associated with atrial fibrillation.
Which NSTEMI ICD Codes Are Billable?
Specific criteria and insurance company guidelines govern the billability of codes.
- I21.4 - Yes, this specific code for NSTEMI is billable.
- I21.A1 - Yes, as it represents a Type 2 myocardial infarction, including NSTEMI.
- I21.A9 - Yes, it is billable when NSTEMI fulfills specific criteria.
- I22.1 - Yes, it can be billed when it represents a subsequent episode of NSTEMI.
- I22.2 - Yes, this is billable for recurrent NSTEMI impacting other areas of the heart.
- I48.91 - Yes, when NSTEMI is associated with atrial fibrillation.
Clinical Information
NSTEMI is a severe medical condition where the blood supply to part of the heart decreases, causing heart cells to die. This can result in serious health issues.
- A partially blocked coronary artery typically causes it.
- It represents a more severe condition than angina but is generally less serious than a full-blown myocardial infarction (heart attack).
- Symptoms include chest pain, discomfort, shortness of breath, nausea, and fatigue.
- EKG changes and elevated cardiac enzymes diagnose it.
- NSTEMI treatment involves medications, coronary angiography, and possibly revascularization (improving blood supply to the heart).
Synonyms Include:
- Non-ST Segment Elevation Heart Attack
- Partial Heart Attack
- Minor Heart Attack
- Non-ST Elevation Acute Coronary Syndrome
- Subendocardial Myocardial Infarction

Commonly asked questions
NSTEMI and STEMI are both types of heart attacks, but they differ in severity and EKG changes. STEMI typically indicates a complete coronary artery blockage, whereas NSTEMI indicates a partial blockage.
Treatment typically includes medications to prevent blood clotting and restore blood flow, along with procedures like coronary angiography and possibly revascularization.
Yes, lifestyle modifications like a healthy diet, regular exercise, quitting smoking, and managing stress can reduce the risk of NSTEMI by improving heart health.
