ISCHEMIC HEART DISEASE (410-414)

• Includes: that with mention of hypertension
• Use additional code to identify presence of hypertension (401.0-405.9)
• 410 Acute myocardial infarction
  • Includes: cardiac infarction
    • coronary (artery):
      • embolism
      • occlusion
      • rupture
      • thrombosis
    • infarction of heart, myocardium, or ventricle
    • rupture of heart, myocardium, or ventricle
    • any condition classifiable to 414.1-414.9 specified as acute or with a stated duration of 8 weeks or less
  • The following fifth-digit subclassification is for use with category 410:
    • 0 episode of care unspecified
      • Use when the source document does not contain sufficient information for the assignment of fifth-digit 1 or 2.
    • 1 initial episode of care
• Use fifth-digit 1 to designate the first episode of care (regardless of facility site) for a newly diagnosed myocardial infarction. The fifth-digit 1 is assigned regardless of the number of times a patient may be transferred during the initial episode of care.
  • 2 subsequent episode of care
    • Use fifth-digit 2 to designate an episode of care following the initial episode when the patient is admitted for further observation, evaluation or treatment for a myocardial infarction that has received initial treatment, but is still less than 8 weeks old.
