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

How is NSTEMI different from STEMI?

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.

What is the typical treatment for NSTEMI?

Treatment typically includes medications to prevent blood clotting and restore blood flow, along with procedures like coronary angiography and possibly revascularization.

Can lifestyle changes prevent NSTEMI?

Yes, lifestyle modifications like a healthy diet, regular exercise, quitting smoking, and managing stress can reduce the risk of NSTEMI by improving heart health.
