What does MI mean in a heart?

Infarction means death of a tissue or necrosis. Acute MI means death of the tissues of the heart muscle. The heart pumps blood through the body in a cyclic manner by powerful contraction and relaxation of the heart muscle. The heart muscles require oxygen, glucose, and other nutrients to survive and to work.

What causes MI in the heart?

Coronary circulation. The major cause of MI is atherosclerosis — plaque formed in the coronary artery, reducing the lumen of the artery and obstructing blood flow. Plaques can become unstable, rupture, and promote the formation of a blood clot in an artery; this can occur in minutes.

What is MI type 2?

Type 2 MI, due to demand ischemia or secondary to ischemic balance, is assigned to code I21.A1 with a code for the underlying cause.

What causes tissue death in the myocardium?

There are other causes, as well, which may reduce the blood supply to the myocardium such as spasm of coronary artery, some infections, high fever, and complication of certain procedures (e.g., coronary artery bypass grafting (CABG)).

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.

What is the I-10 code for angina pectoris?

I-10 has combination codes for atherosclerotic heart disease with angina pectoris. The subcategories for these codes are I25.11, Atherosclerotic heart disease of native coronary artery with angina pectoris and I25.7, Atherosclerosis of coronary artery bypass graft (s) and coronary artery of transplanted heart with angina pectoris.

What is a combination code for angina?

Combination codes include Coronary Artery Disease (CAD) plus all types of Angina. These combination codes include native arteries as well as CAD of bypass graft (s). The time frame for Acute Myocardial Infarction (AMI) codes have changed from eight (8) weeks or less to four (4) weeks or less (within 28 days).

What is the I50 code?

Heart conditions classified to I50.-I51.9, are assigned to a code from category I11, Hypertensive heart disease, when a causal relationship is stated (due to hypertension) or implied (hypertensive). Use an additional code from category I50, Heart failure, to identify the type of heart failure in those patients with heart failure.

What is the code for cerebrovascular disease?

For hypertensive cerebrovascular disease, first assign the appropriate code from categories I60-I69, followed by the appropriate hypertension code.

What is a category I69?

Category I69 is used to indicate conditions classifiable to categories I60-I67 as the causes of sequel (neurologic deficits), they themselves classified elsewhere. These “late effects” include neurologic deficits that persist after initial onset of conditions classifiable to categories I60-I67. The neurologic deficits caused by cerebrovascular disease may be present from the onset or may arise at any time after the onset of the condition classifiable to categories I60-I67.

When to use I22 code?

A code from category I22, Subsequent STEMI and NSTEMI, is to be used when a patient who has suffered an AMI has a new AMI within the 4 week time frame of the initial AMI. A code from category I22 must be used in conjunction with a code from category I21. The sequencing of the I22 and I21 codes depends on the circumstances of the encounter.

What is the appropriate code for chronic kidney disease?

The appropriate code from category N18, Chronic kidney disease, should be used as a secondary code with a code from category I13 to identify the stage of chronic kidney disease.

What is the new code for MI?

The new code set also will add I21.A1 ( Myocardial infarction type 2 ), which includes MIs due to demand ischemia or ischemic imbalance. For MI types 3, 4a, 4b, 4c, and 5, you’ll use I21.A9 ( Other myocardial infarction type ). Type 3 involves sudden cardiac death, type 4 is PCI-related, and type 5 is CABG-related. Finally, you’ll have new code I21.9 ( Acute myocardial infarction, unspecified) to use when documentation doesn’t support using a more specific code.

What is the code for type 2 AMI?

Another helpful lesson you’ll learn from the new OGs is that if documentation specifies STEMI or NSTEMI for type 2 AMI, you still should report type 2 code I21.A1. Leave I21.0- to I21.4 for type 1 AMIs.

What is I.C.9.e.5?

I.C.9.e.5: This text is brand new for 2018 and basically tells you to follow the sequencing guidelines in the official code set when reporting AMI types 2 to 5.

Which organizations approve ICd 10 codes?

The American Hospital Association (AHA), American Health Information Management Association (AHIMA), Centers for Medicare and Medicaid Services (CMS), and National Center for Health Statistics (NCHS) all approve these guidelines, and HIPAA requires adherence to the OGs when assigning ICD-10-CM diagnosis codes.

Can I21.A1 be used for subsequent AMI?

You should not assign I22.- for other types of subsequent AMIs. Use I21.A1 for subsequent type 2 AMI, and use I21.A9 for subsequent type 4 and 5 AMI. (Remember, type 3 AMI involves sudden cardiac death.)

Is there a change to I.C.9.e.3?

I.C.9.e.3: There’s no change to this text, which tells you that if documentation states the site of a subendocardial MI (NSTEMI), you should report the subendocardial code even though it doesn’t specify site. In other words, don’t be tempted to use a site-specific STEMI code for NSTEMI just because you know the site.
