I24.9 is a billable ICD code used to specify a diagnosis of acute ischemic heart disease, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code I249 is used to code Acute coronary syndrome

Acute coronary syndrome (ACS) refers to a group of conditions due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. The most common symptom is chest pain, often radiating to the left arm or angle of the jaw, pressure-like in character, and associated with nausea and sweating. Acute coronary syndrome usually occurs as a result of one of three problems: ST elevation myocardial infarction (STEMI, 30%), non ST elevation myocardial infarction (NSTEMI, 25%), or unstable angina (38%).
