Acute myocardial infarction, unspecified
We examine Medicare costs and survival gains for Acute Myocardial Infarction (AMI) during 1986–2002. Like Cutler and McClellan, we find overall gains in post-AMI survival more than justified the increases in costs during this period. Since 1996, ...
myocardial infarction: old (I25. 2) specified as chronic or with a stated duration of more than 4 weeks (more than 28 days) from onset (I25.
A heart attack is also known as a myocardial infarction....The three types of heart attacks are:ST segment elevation myocardial infarction (STEMI)non-ST segment elevation myocardial infarction (NSTEMI)coronary spasm, or unstable angina.
Acute myocardial infarction is myocardial necrosis resulting from acute obstruction of a coronary artery. Symptoms include chest discomfort with or without dyspnea, nausea, and diaphoresis. Diagnosis is by ECG and the presence or absence of serologic markers.
I51. 9 - Heart disease, unspecified | ICD-10-CM.
Type 2 MI is the most common type of MI encountered in clinical settings in which is there is demand-supply mismatch resulting in myocardial ischemia. This demand supply mismatch can be due to multiple reasons including but not limited to presence of a fixed stable coronary obstruction, tachycardia, hypoxia or stress.
Coronary artery bypass grafting (CABG)–related MI is termed type 5 MI. Coronary procedure–related MI ≤48 hours after the index procedure is arbitrarily defined by an elevation of cTn values >5 times for type 4a MI and >10 times for type 5 MI of the 99th percentile URL in patients with normal baseline values.
Acute Myocardial Infarction (heart attack) Acute myocardial infarction, also known as a heart attack, is a life-threatening condition that occurs when blood flow to the heart muscle is abruptly cut off, causing tissue damage. This is usually the result of a blockage in one or more of the coronary arteries.
It can feel like uncomfortable pressure, squeezing, fullness or pain. Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach. Shortness of breath.
Myocardial ischemia occurs when blood flow to the heart muscle (myocardium) is obstructed by a partial or complete blockage of a coronary artery by a buildup of plaques (atherosclerosis). If the plaques rupture, you can have a heart attack (myocardial infarction).

That code is I10, Essential (primary) hypertension. As in ICD-9, this code includes “high blood pressure” but does not include elevated blood pressure without a diagnosis of hypertension (that would be ICD-10 code R03. 0).
Heart failure is assumed to be due to hypertension when coded using I11. 0, “Hypertensive heart disease with heart failure.” In ICD-10, the word “with” presumes a causal relationship between the two conditions linked by this term.
Acute myocardial infarction, unspecified 1 I21.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. 2 The 2021 edition of ICD-10-CM I21.9 became effective on October 1, 2020. 3 This is the American ICD-10-CM version of I21.9 - other international versions of ICD-10 I21.9 may differ.

It is characterized by a severe and rapid onset of symptoms that may include chest pain, often radiating to the left arm and left side of the neck, dyspnea, sweating, and palpitations. ...
The patient is admitted to the hospital on June 1 and is diagnosed with acute myocardial infarction, unspecified ( ICD-10 code I21.9). On July 7, the provider sees the patient for a follow-up visit and the patient receives care related to the myocardial infarction.
Myocardial Infarction has defined six types of MI. The two most commonly encountered are type 1 (primarily due to CAD) and type 2 (primarily due to myocardial supply/demand mismatch). For these two types, MI is defined as myocardial necrosis identified by a rise and/or fall of cardiac biomarkers to or from a level greater than the 99th percentile of the upper reference limit.
An MI is coded as acute for a period of four weeks following onset; after that, it is assigned code I25.2 (old MI). Codes in category I22 are also provided for a subsequent type 1 MI (STEMI or NSTEMI), defined as another MI occurring within four weeks of a previous (initial) MI. In this situation, a code from I21 is also assigned for the initial MI.
Type 1 is the classic spontaneous MI, primarily due to coronary artery disease (CAD) with atherosclerotic plaque rupture, ulceration, fissuring, erosion, or dissection causing intraluminal thrombosis. Occasionally type 1 occurs in the absence of CAD with spontaneous thrombosis of a coronary artery (particularly in women). Type 1 includes Q-wave infarction, ST-elevation MI, and non-ST elevation MI.
To understand the changes to the OGs, you first have to learn the new references to MI types 1 to 5 in the diagnosis codes. Provider documentation will need to specify MI type to assist with choosing the most accurate code.
The 2018 OGs include revisions and all new text to help you understand how to apply the code changes. If you haven’t spent a lot of time reviewing OGs in the past, now’s a good time to start. They provide authoritative guidance that may not be available in the official code set.
