Athscl heart disease of native coronary artery w/o ang pctrs

This code signifies the presence of coronary artery disease (CAD) due to atherosclerosis affecting the patient's original, non-grafted coronary arteries. It specifically indicates that the patient is not currently experiencing angina pectoris or anginal equivalent symptoms related to this condition. This represents a chronic, stable form of atherosclerotic heart disease.

Use this code for patients diagnosed with documented atherosclerotic heart disease of their native coronary arteries who are asymptomatic for angina. This is appropriate when documentation explicitly states "atherosclerotic heart disease without angina," or when CAD is present but no anginal symptoms are reported or treated. Supporting documentation includes diagnostic reports (e.g., angiography, stress tests) confirming CAD and physician notes indicating the absence of angina.

• Do not use this code if the patient is experiencing any form of angina; instead, select a code from the I20 series or a more specific I25.11- code.
• Ensure documentation specifies "native coronary artery" to differentiate from bypass graft involvement (I25.7- series).
• This code is often a secondary diagnosis, as the patient may be seen for complications or management of the underlying CAD.
