Accurate coding for myocardial infarction (MI) is essential for effective billing and claim accuracy. This guide covers the ICD-10 codes for different types of MI, including STEMI, NSTEMI, and Type 2 MI, and provides tips for handling evolving conditions.

The ICD‐10‐CM codes for acute myocardial infarction are located in chapter 9, Diseases of the Circulatory System, and are coded by site (such as anterolateral wall or true posterior wall), type (STEMI or NSTEMI) and temporal parameter (initial, subsequent, or old). There are two categories for acute myocardial infarction in ICD-10-CM. They are:

MI is documented and coded based on: • Site • Type: 1 (STEMI, NSTEMI), 2 (due to embolisms), 3 (causes death), 4A (due to angioplasty), 4 (due to stent thrombosis), 5 (due to bypass graft) • Chronology of an AMI Myocardial Infarction Classification Acute MI (I21.0-) to (I21.3) STEMI of [site] (I21.4) NSTEMI (I21.9) – unspecified site

Apr 16, 2021 · 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).

Knowing the right ICD-10 codes is essential for complete documentation and invoicing for myocardial infarction (MI). This includes a comprehensive list of these codes, with a focus on their use in different forms of MI, including the crucial distinctions required for Type 2 …

Updates to the 2018 ICD-10-CM now require MI to be coded by type. MI codes have now been expanded to reflect clinical classifications, as defined by the Task Force for the Universal Definition of Myocardial Infarction. The five types of MI classifications and corresponding codes:

Nov 10, 2024 · These codes provide a standardized way to document various types of myocardial infarctions and are essential for effective treatment and management. Breakdown of Myocardial Infarction Codes. The ICD-10-CM codes for myocardial infarction include:

Myocardial Infarction: Irreversible ischemic “injury” to the myocardium that occurs when acute myocardial ischemia causes acute myocardial injury. Type 1 MI: Spontaneous MI related to ischemia due to a primary coronary event such as plaque erosion and /or rupture, fissuring or …

Dec 1, 2018 · Type 1 – Spontaneous MI is related to plaque erosion and/or rupture, fissuring, or dissection. Type 2 – MI due to ischemia results from increased oxygen demand or decreased supply (e.g., coronary artery spasm, coronary embolism, anemia, arrhythmias, high or …

There are five classifications of MIs. Type 1 MIs are assigned to codes I21.0-I21.4. Type 2 MIs are assigned to I21.A1 with a code for the underlying cause. Acute MIs type 3-5 are assigned to code I21.A9. MIs are classified as acute if the duration is four weeks or less.
