Nonocclusive coronary artery atherosclerosis. Coronary disease that has not progressed to the point of causing significant occlusion (blockage) of the coronary arteries.
Code I25* is the diagnosis code used for Chronic Ischemic Heart Disease, also known as Coronary artery disease (CAD). It is a is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden coronary death.
“If somebody's having chest pain it generally means that they have a plaque that is blocking more than 70 percent of the coronary artery. So we call that obstructive coronary disease.” WHEN PATIENTS HAVE SMALLER AMOUNTS OF PLAQUE, THEY ARE DIAGNOSED WITH WHAT IS KNOWN AS NON-OBSTRUCTIVE CORONARY DISEASE.

Coronary artery disease (CAD) is the most common type of heart disease in the United States. It is sometimes called coronary heart disease or ischemic heart disease. For some people, the first sign of CAD is a heart attack. You and your health care team may be able to help reduce your risk for CAD.
They recognize that your heart's arteries sometimes suffer from non-obstructive coronary artery disease. This less common form of CAD occurs when your heart's arteries inappropriately constrict, malfunction after branching into tiny vessels, or are squeezed by the overlying heart muscle.
In this study, non-obstructive CAD was defined as blood vessels that were less than 70 percent blocked. “Unlike obstructive CAD, which blocks blood flow, non-obstructive CAD may initially appear less threatening on angiography tests, but it appears to have significant risk for heart attack and death” said Thomas M.
Among37 674 patients, 8384 patients (22.3%) had nonobstructive CAD and 20 899 patients (55.4%) had obstructive CAD.
When cholesterol and other debris collect in the walls of your arteries, they harden, reducing blood flow to the heart. When this series of events occurs in the coronary artery, doctors call the plaque accumulation coronary atherosclerosis, or coronary artery disease.
