Valid for Submission
I24.8 is a billable diagnosis code used to specify a medical diagnosis of other forms of acute ischemic heart disease. The code I24.8 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code I24.8 might also be used to specify conditions or terms like acute coronary insufficiency, coronary microvascular dysfunction, disorder of oxygen transport, increased oxygen demand, ischemia co-occurrent and due to increased oxygen demand , left ventricular thrombus, etc.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code I24.8:
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- myocardial infarction due to demand ischemia I21.A1
Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code I24.8 are found in the index:
- - Insufficiency, insufficient
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Acute coronary insufficiency
- Coronary microvascular dysfunction
- Disorder of oxygen transport
- Increased oxygen demand
- Ischemia co-occurrent and due to increased oxygen demand
- Left ventricular thrombus
- Microinfarct of heart
- Myocardial ischemia
- Preinfarction syndrome
- Subendocardial ischemia
Convert I24.8 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code I24.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Coronary Artery Disease
Coronary artery disease (CAD) is the most common type of heart disease. It is the leading cause of death in the United States in both men and women.
CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed. This is due to the buildup of cholesterol and other material, called plaque, on their inner walls. This buildup is called atherosclerosis. As it grows, less blood can flow through the arteries. As a result, the heart muscle can't get the blood or oxygen it needs. This can lead to chest pain (angina) or a heart attack. Most heart attacks happen when a blood clot suddenly cuts off the hearts' blood supply, causing permanent heart damage.
Over time, CAD can also weaken the heart muscle and contribute to heart failure and arrhythmias. Heart failure means the heart can't pump blood well to the rest of the body. Arrhythmias are changes in the normal beating rhythm of the heart.
