The anterior region of the lateral wall, surrounding the ostium of the right appendage, is often referred to as the right atrial free wall.
An anterior myocardial infarction (MI) is a heart attack or cessation of blood flow to the heart muscle that involves the anterior side of the heart. An anterior MI is characterized by the presence of ST elevation in the anterior leads V3 and V4.
I63. 9 - Cerebral infarction, unspecified | ICD-10-CM.
Inferior wall myocardial infarction (MI) occurs from a coronary artery occlusion with resultant decreased perfusion to that region of the myocardium. Unless there is timely treatment, this results in myocardial ischemia followed by infarction.

ICD-10-CM Code for ST elevation (STEMI) myocardial infarction of inferior wall I21. 1.
410.51 is a legacy non-billable code used to specify a medical diagnosis of acute myocardial infarction of other lateral wall, initial episode of care. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart.
410.52 is a legacy non-billable code used to specify a medical diagnosis of acute myocardial infarction of other lateral wall, subsequent episode of care. This code was replaced on September 30, 2015 by its ICD-10 equivalent.
The following crosswalk between ICD-9 to ICD-10 is based based on the General Equivalence Mappings (GEMS) information:
Each year over a million people in the U.S. have a heart attack. About half of them die. Many people have permanent heart damage or die because they don't get help immediately. It's important to know the symptoms of a heart attack and call 9-1-1 if someone is having them. Those symptoms include
General Equivalence Map Definitions The ICD-9 and ICD-10 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.
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.
