 2007 ICD-9-CM Diagnosis 414.8
Other specified forms of chronic ischemic heart disease On October 1, 2008 the 2009 ICD-9-CM codes came into effect. Therefore, this code may be out of date.
The 2009 version of ICD-9-CM 414.8 can be accessed here. - 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 ARTERIOSCLEROSIS), 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).
