Mar 06, 2019 · ICD-10-CM code I21.A1 is reported for a current MI due to demand ischemia. Ischemia is due to oxygen starvation to some or all of the heart. It will usually cause EKG changes and often will cause enzyme elevations (e.g., troponin I, creatine kinase-muscle/brain), but ischemia does not result in permanent damage to myocardium (heart muscle tissue).

Applicable To Myocardial infarction due to demand ischemia Myocardial infarction secondary to ischemic imbalance Code First the underlying cause, such as: anemia ( D50.0- D64.9) chronic obstructive pulmonary disease ( J44.-)

A: ICD-10-CM code I24. 8 would be used for demand ischemia where the patient did not have a current myocardial infarction (MI). This code also covers other forms of ischemic heart diseases.Mar 6, 2019
Demand ischemia is another type of heart attack for which blockages in the arteries may not be present. It occurs when a patient's heart needs more oxygen than is available in the body's supply. It may occur in patients with infection, anemia, or tachyarrhythmias (abnormally fast heart rates).Sep 12, 2015
When you look up the code I24. A1 for a Type 2 MI, the inclusions under the main term include MI due to demand ischemia, and also MI secondary to ischemic imbalance.May 16, 2019
Demand ischemia (411.89) is a transitory imbalance that may be caused by exercise, tachycardia, or emotion. It is characterized by angina because of the increased oxygen demand.
Demand ischemia can occur without a myocardial infarction (MI), so if there is no mention of an MI, a query might be appropriate. The condition is frequently confused with type 2 MIs, and clarification may be needed to code the diagnosis reflective of the condition.Nov 3, 2017
Cardiac ischemia is assessed by the electrocardiogram (ECG) and interpretation of the symptoms. An initial troponin measurement should be made as well as assessment of renal function and other appropriate laboratory tests and investigations guided by the clinical presentation of the patient.May 18, 2016
Demand ischemia should be reserved for when there is evidence of supply-demand mismatch causing ischemia without an elevated troponin above the 99th percentile. If the troponin is > 99th percentile the diagnosis is a Type 2 MI.

For patients with type 1 MI, the focus is on aggressive antithrombotic therapy and consideration of urgent coronary angiography and revascularization. For patients with type 2 MI, the focus is on treating the extracardiac stressor precipitating the myocardial oxygen supply and demand imbalance.Apr 21, 2021
The term ischemia means that blood flow to a tissue has decreased, which results in hypoxia, or insufficient oxygen in that tissue, whereas infarction goes one step further and means that blood flow has been completely cut off, resulting in necrosis, or cellular death.
