icd 9 cm code for non st elevation myocardial infarction

What is the CPT code for non‐ST elevation myocardial infarction?

Code I21.4, Non‐ST elevation (NSTEMI) myocardial infarction, is used for non‐ST elevation MI and nontransmural MIs. If NSTEMI evolves to STEMI, assign the STEMI code. If STEMI converts to NSTEMI due to thrombolytic therapy, it is still coded as STEMI.

How do you code a STEMI and NSTEMI?

What is STEMI and NSTEMI?

STEMI results from complete and prolonged occlusion of an epicardial coronary blood vessel and is defined based on ECG criteria..NSTEMI usually results from severe coronary artery narrowing, transient occlusion, or microembolization of thrombus and/or atheromatous material.

Is NSTEMI considered acute?

NSTEMI is a type of acute coronary syndrome, which is an umbrella term for three conditions that cause a lack of blood flow to your heart. The other two conditions are STEMI and unstable angina (sudden chest pain from lack of blood flow, usually while resting, but not as dangerous as a heart attack).

What is the main term in myocardial infarction?

Myocardial infarction: A heart attack. Abbreviated MI. The term "myocardial infarction" focuses on the myocardium (the heart muscle) and the changes that occur in it due to the sudden deprivation of circulating blood. The main change is necrosis (death) of myocardial tissue.

How long is a myocardial infarction considered acute?

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)

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.

What is the ICd 10 code for AMI?

The ICD-10-CM codes for AMI are in chapter 9, Diseases of the Circulatory System, and are coded by site (such as the anterolateral wall or true posterior wall), type (ST-elevation myocardial infarction (STEMI) or non-STEMI (NSTEMI)) and temporal parameter (initial, subsequent, or old).#N#A type 1 MI described as acute or with a duration of four weeks or less with STEMI is classified in categories:#N#I21.0 ST elevation (STEMI) myocardial infarction of anterior wall#N#I21.1 ST elevation (STEMI) myocardial infarction of inferior wall#N#I21.2 ST elevation (STEMI) myocardial infarction of other sites#N#I21.3 ST elevation (STEMI) myocardial infarction of unspecified site#N#The fourth digit indicates the wall involved. A NSTEMI is coded with I21.4 Non-ST elevation (NSTEMI) myocardial infarction. A new unspecified code in 2018 from the same subcategory (I21.9 Acute myocardial infarction, unspecified) should not be assigned unless no information regarding the site and type is documented. If only the type 1 STEMI or transmural MI without the site is documented, assign code I21.3.#N#New guidelines (I.C.9.e.4) specify that a code from category I22 Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction is only assigned for patients admitted with a new type 1 or unspecified AMI any time during the first four weeks’ time frame after the initial AMI occurred and should not be used for type 2 AMI. For subsequent type 2 AMI, use only code I21.A1 Myocardial infarction type 2.#N#For MI due to demand ischemia or secondary to ischemic balance, assign I21.A1 (type 2 MI) and not I24.8 Other forms of acute ischemic heart disease ( I.C.9.e.5).#N#Artery site specification does not need to be documented to code type 2 MI because that is not relevant. It is important, however, to document a serious prognosis as to the cause of the underlying condition. The “code also the underlying cause, if known and applicable” instructional note has been added to the type 2 MI. This note includes an example of conditions such as anemia, chronic obstructive pulmonary disease, heart failure, paroxysmal tachycardia, renal failure, and shock. For example, if a patient is admitted for an MI, and has any of these other conditions, the underlying cause is also coded in addition to the code for type 2 AMI. Sequencing of type 2 AMI or the underlying cause depends on the circumstances of admission. When the documentation specifically describes the type 2 AMI as NSTEMI or STEMI, assign I21.A1, not I21.1-I21.4 (which are only for type 1 AMI).#N#For other documented types of AMI (types 3, 4a, 4b, 4c and 5) assign I21.A9 Other myocardial infarction type.

What causes MI type 1?

Type 1 MI is caused by an acute atherothrombotic coronary event. This is usually secondary to atherosclerotic plaque rupture, ulceration, fissuring, erosion, or dissection resulting in intraluminal thrombus.#N#Type 2 MI is a cell death in a non-anatomical distribution based on supply (e.g., hypoxemia, anemia, and hypotension) and demand (e.g. tachycardia, hypertension) mismatch. A coronary vasospasm and/or endothelial dysfunction have also the potential to cause type 2 AMI. The Third Universal Definition of Myocardial Infarction defines type 2 AMI as instances other than coronary artery disease (CAD) in which an oxygen supply/demand imbalance leads to myocardial injury with necrosis that is not caused by acute coronary syndrome, including arrhythmias, aortic dissection, severe aortic valve disease, hypertrophic, cardiomyopathy, shock, respiratory failure, severe anemia, hypertension with or without left ventricular hypertrophy, coronary spasm, coronary embolism or vasculitis, and coronary endothelial dysfunction.
