Athscl bypass of cor art of txplt heart w unsp ang pctrs

This code signifies the presence of atherosclerosis affecting a coronary artery bypass graft (CABG) in a patient who has undergone a heart transplant. The patient is experiencing angina pectoris, but the specific type or cause of the angina is not documented. This indicates a complication related to the transplanted heart's revascularization.

Use this code when documentation clearly states atherosclerosis of a bypass graft in a transplanted heart, accompanied by angina pectoris that is not further specified (e.g., stable, unstable, variant). This typically applies to patients presenting with chest pain or other anginal symptoms after a heart transplant and subsequent CABG, where imaging or diagnostic studies confirm graft atherosclerosis.

• Ensure documentation explicitly states "transplanted heart" and "bypass graft" to differentiate from native coronary artery disease.
• If the type of angina is specified (e.g., unstable angina), a more specific code from the I25.76 series should be used.
• Always sequence this code after the primary reason for the encounter, if applicable, unless it is the primary diagnosis.
