  • Ischemic congestive cardiomyopathy
  • Myocardial ischemia

Clinical Information
  • 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, to obstruction by a thrombus, 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).
  • Blood deficiency in the myocardium caused by a constriction or obstruction of its blood vessels; frequently occurs in conjunction with hypoxia, which is reduction in oxygen supply.
414.8 Excludes
  • coronary insufficiency (acute) (411.89)
Applies To
  • Chronic coronary insufficiency
  • Ischemia, myocardial (chronic)
  • Any condition classifiable to 410 specified as chronic, or presenting with symptoms after 8 weeks from date of infarction

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 414.8 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
