ICD-10 code I21. 9 for Acute myocardial infarction, unspecified is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
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.
ICD-10 code: I21. 4 Acute subendocardial myocardial infarction.
379.93 - Redness or discharge of eye. ICD-10-CM.
Coding Guidance An acute MI should be reported for up to 4 weeks (28 days) with a code from category I21. Encounters for care related to the MI after the 4‐week timeframe should be coded with the appropriate aftercare code. An old or healed MI, not requiring further care, should be coded as I25.
ST segment elevation myocardial infarction (STEMI) non-ST segment elevation myocardial infarction (NSTEMI) coronary spasm, or unstable angina.
Subsequent non-ST elevation (NSTEMI) myocardial infarction I22. 2 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM I22. 2 became effective on October 1, 2021.

ICD-10-CM Code for Non-ST elevation (NSTEMI) myocardial infarction I21. 4.

Unspecified epiphora, unspecified side 209 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM H04. 209 became effective on October 1, 2021. This is the American ICD-10-CM version of H04.
In outpatient settings you do not code probable, possible, or rule out diagnosis. You could code the symptoms or the reason they came into the office.
A myocardial infarction (commonly called a heart attack) is an extremely dangerous condition caused by a lack of blood flow to your heart muscle.
Myocardial infarction (MI): The damaging or death of an area of the heart muscle (myocardium) resulting from a blocked blood supply to that area. It's also the medical term for a heart attack.
A heart attack (myocardial infarction) happens when one or more areas of the heart muscle don't get enough oxygen. This happens when blood flow to the heart muscle is blocked.
The word myocardial refers to the heart muscle or 'myocardium'. Infarction refers to a blockage in blood supply.
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.
The 2022 edition of ICD-10-CM I21.9 became effective on October 1, 2021.
Old or healed Myocardial Infarctions not requiring further care may be assigned ICD-10 code I25.2 if supported by documentation in the chart.
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.
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.
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.
