I25.6 is a billable ICD-10 code used to specify a medical diagnosis of silent myocardial ischemia. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The code is commonly used in cardiology medical specialties to specify clinical concepts such as selected atherosclerosis, ischemia, and infarction.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Myocardial ischemia
- Silent coronary vasospastic disease
- Silent myocardial infarction
- Silent myocardial ischemia
- Myocardial Ischemia-. a disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. the decreased blood flow may be due to narrowing of the coronary arteries (coronary artery disease), to obstruction by a thrombus (coronary thrombosis), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (myocardial infarction).
- Silent Myocardial Infarction-. a history of myocardial infarction in the absence of clinical symptoms and positive electrocardiographic findings.
- Silent Myocardial Infarction by ECG Finding|Silent Myocardial Infarction by EKG Finding-. an electrocardiographic finding that a myocardial infarction has occurred concurrently with the absence of clinical symptoms.

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.
