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). 414.9 is a specific code that can be used to specify a diagnosis 414.9 contains 12 index entries View the ICD-9-CM Volume 1 414.* hierarchy Alternate Terminology Ischemic heart disease NOS  Index entries containing 414.9: Change(s) (of) - see also Removal of coronary (see also Ischemia, heart) 414.9 Damage coronary (see also Ischemia, heart) 414.9 Deformity 738.9 artery (congenital) (peripheral) NEC (see also Deformity, vascular) 747.60 coronary (congenital) 746.85 acquired (see also Ischemia, heart) 414.9 coronary artery (congenital) 746.85 acquired (see also Ischemia, heart) 414.9 Degeneration, degenerative heart (brown) (calcareous) (fatty) (fibrous) (hyaline) (mural) (muscular) (pigmentary) (senile) (with arteriosclerosis) (see also Degeneration, myocardial) 429.1 ischemic 414.9 Disease, diseased - see also Syndrome coronary (see also Ischemia, heart) 414.9 congenital 746.85 ostial, syphilitic 093.20 aortic 093.22 mitral 093.21 pulmonary 093.24 tricuspid 093.23 heart (organic) 429.9 coronary 414.9 ischemic (chronic) (see also Ischemia, heart) 414.9 acute (see also Infarct, myocardium) 410.9 without myocardial infarction 411.89 with coronary (artery) occlusion 411.81 asymptomatic 412 diagnosed on ECG or other special investigation but currently presenting no symptoms 412 Ischemia, ischemic 459.9 cardiac (see also Ischemia, heart) 414.9 coronary (chronic) (see also Ischemia, heart) 414.9 heart (chronic or with a stated duration of over 8 weeks) 414.9 acute or with a stated duration of 8 weeks or less (see also Infarct, myocardium) 410.9 without myocardial infarction 411.89 with coronary (artery) occlusion 411.81 subacute 411.89 Lesion(s) coronary artery (see also Ischemia, heart) 414.9
