ICD-10-CM Code for Non-ST elevation (NSTEMI) myocardial infarction I21. 4.
A non-ST-elevation myocardial infarction (NSTEMI) is a type of heart attack that usually happens when your heart's need for oxygen can't be met. This condition gets its name because it doesn't have an easily identifiable electrical pattern (ST elevation) like the other main types of heart attacks.
A Non-ST-Elevation Myocardial Infarction is a type of heart attack, often referred to as NSTEMI or a non-STEMI. In medical terminology, a heart attack is a myocardial infarction. An NSTEMI is a less severe form of heart attack than the STEMI because it inflicts less damage to the heart.
Non-ST-elevation myocardial infarction (NSTEMI) is an acute ischemic event causing myocyte necrosis. The initial ECG may show ischemic changes such as ST depressions, T-wave inversions, or transient ST elevations; however, it may also be normal or show nonspecific changes.
NSTEMI is caused by a block in a minor artery or a partial obstruction in a major artery. STEMI occurs when a ruptured plaque blocks a major artery completely.
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).
Types 1 and 2 MI are spontaneous events, while type 4 and type 5 are procedure-related; type 3 MI is identified only after death. Most type 1 and type 2 MI present as non-ST-elevation MI (NSTEMI), although both types can also present as ST-elevation MI.
The distinguishing feature between unstable angina and non-STEMI is the presence of elevated cardiac markers, such as troponin, which implies myocardial damage. Patient history alone is insufficient to make a diagnosis of acute coronary syndrome.
STEMI vs NSTEMI – Which is Worse? The bottom line is that both are just as bad. STEMI is seen as more of an immediate emergency because there is a known total occlusion of a heart vessel that needs opening back up urgently. In terms of long-term outcomes, they have equal health implications.
The etiology of NSTEMI varies as there are several potential causes. These include tobacco abuse, lack of physical activity, high blood pressure, high cholesterol, diabetes, obesity, and family history.
Introduction and objectives: Occasionally, coronary arteries without significant stenosis are observed during invasive treatment of acute non-ST-elevation myocardial infarction (NSTEMI).

Most patients stay in the hospital for about a week or less. Upon returning home, you will need rest and relaxation. A return to all of your normal activities, including work, may take a few weeks to 2 or 3 months, depending on your condition. A full recovery is defined as a return to normal activities.
Coronary artery disease, including the acute coronary syndromes (ACS) of unstable angina, non–ST-segment elevation myocardial infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI), is the most common cause of heart failure (HF).
The five-year survival rate for NSTEMI patients was 51%, 42% among women and 57% among men. The five-year survival rate for STEMI patients was 77%, 68% among women and 80% among men. Five year age-adjusted survival rates were higher for STEMI than NSTEMI (logrank: p <0.01).
I21.4 is a valid billable ICD-10 diagnosis code for Non-ST elevation (NSTEMI) myocardial infarction . It is found in the 2021 version of the ICD-10 Clinical Modification (CM) and can be used in all HIPAA-covered transactions from Oct 01, 2020 - Sep 30, 2021 .
DO NOT include the decimal point when electronically filing claims as it may be rejected. Some clearinghouses may remove it for you but to avoid having a rejected claim due to an invalid ICD-10 code, do not include the decimal point when submitting claims electronically.

Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden coronary death. It is within the group of cardiovascular diseases of which it is the most common type.

This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that while there is no exact mapping between this ICD10 code I21.4 and a single ICD9 code, 410.71 is an approximate match for comparison and conversion purposes.

A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code ( I21) and the excluded code together.
A disorder characterized by gross necrosis of the myocardium; this is due to an interruption of blood supply to the area.
In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere.". Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code.
You should report I21.11, a STEMI code, in this situation, according to the guidelines.
If your cardiologist documents a type 1 non-ST elevation myocardial infarction (NSTEMI) or a nontransmural myocardial infarction, you should report I21.4 (Non-ST elevation (NSTEMI) myocardial infarction).
“It’s still a type 2 AMI and should be coded as I21.A1.”
