Atherosclerosis of CABG w/o angina pectoris

This code signifies the presence of hardening and narrowing of the arteries within a previously implanted coronary artery bypass graft. This condition indicates a failure or deterioration of the bypass graft itself, but the patient is not currently experiencing chest pain (angina).

Apply this code when documentation explicitly states atherosclerosis of a coronary artery bypass graft without any mention of angina pectoris. This is commonly seen in follow-up care for patients post-CABG who are found to have graft disease during imaging or other diagnostic studies, but are asymptomatic for angina.

• Always review documentation for any mention of angina pectoris; if present, a different code from the I25.7x series is required.
• This code is typically a secondary diagnosis, as the primary reason for the encounter may be related to monitoring, medication management, or evaluation of the graft.
• Ensure the documentation specifies "bypass graft" to differentiate from native coronary artery atherosclerosis.
