Atherosclerosis of CABG w unsp angina pectoris

This code describes atherosclerosis affecting a coronary artery bypass graft (CABG) that is not the native coronary artery, in a patient experiencing unspecified angina pectoris. It indicates the presence of plaque buildup within the bypass graft itself, leading to chest pain of an uncharacterized nature.

Use this code when documentation specifies atherosclerosis of a CABG (e.g., saphenous vein graft, internal mammary artery graft) and the patient presents with angina pectoris that is not further specified as stable, unstable, or variant. This applies when the angina is directly attributed to the graft disease.

• Ensure documentation clearly states atherosclerosis of a bypass graft and not a native coronary artery.
• Do not use this code if the angina is specified (e.g., stable, unstable); instead, select a more specific I25.7xx code.
• Remember the Excludes1 note: never code with I20.9 (unspecified angina pectoris without atherosclerosis of other coronary artery bypass graft(s)).
