Other forms of chronic ischemic heart disease

This code represents chronic ischemic heart conditions that do not fit into more specific categories of atherosclerotic heart disease, such as angina pectoris or old myocardial infarction. It encompasses a range of persistent myocardial oxygen supply-demand imbalances due to coronary artery disease, manifesting in various non-specific ways.

Use this code when documentation indicates chronic ischemic heart disease without a more precise diagnosis like unstable angina, stable angina, or a history of myocardial infarction. This is appropriate for conditions like ischemic cardiomyopathy not specified as due to a prior MI, or other chronic forms of myocardial ischemia. Documentation should clearly state "other chronic ischemic heart disease" or describe a chronic ischemic process not classifiable elsewhere.

• Do not use this code if a more specific diagnosis of chronic ischemic heart disease (e.g., I25.11 for atherosclerotic heart disease of native coronary artery with angina pectoris) is documented.
• Always review the medical record for specific details regarding the type and manifestation of chronic ischemic heart disease to ensure the most precise code is selected.
• Consider sequencing with codes for underlying causes, such as atherosclerosis of coronary arteries (I25.10), if documented.
