Atherosclerosis of CABG, unsp, w unsp angina pectoris

This code signifies the presence of atherosclerosis affecting one or more coronary artery bypass grafts, where the specific type of graft (e.g., saphenous vein, internal mammary artery) is not documented. The patient is also experiencing angina pectoris, but the specific type or cause of the angina is not specified.

This code is appropriate when documentation confirms atherosclerotic changes within a previously placed coronary artery bypass graft, and the patient presents with anginal symptoms without further specification of the angina type. It should be used when the type of bypass graft is not identified in the medical record.

• Do not use this code if the angina pectoris is clearly documented as being due to native coronary artery disease without graft involvement.
• Always strive for greater specificity regarding the type of bypass graft (e.g., I25.719, I25.729) and the type of angina (e.g., I25.701, I25.702) if available in the documentation.
• This code is an "Excludes1" for I20.9, meaning they should never be reported together; I20.9 represents angina without documented graft atherosclerosis.
