Athscl bypass of cor art of transplanted heart w/o 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. Importantly, the patient is not experiencing angina pectoris (chest pain) as a symptom of this graft disease. It indicates a chronic, progressive hardening and narrowing of the transplanted heart's bypass vessels.

This code is appropriate when documentation confirms atherosclerosis within a coronary artery bypass graft of a transplanted heart, and there is no mention of angina. Supporting documentation would include diagnostic reports (e.g., angiography, cardiac catheterization) detailing the graft disease and physician notes explicitly stating the absence of angina.

• Ensure documentation clearly specifies "transplanted heart" and "bypass graft" to differentiate from native coronary artery disease.
• Verify the absence of angina pectoris; if angina is present, a different code (I25.76) must be used.
• This code typically represents a chronic condition and may be sequenced as a secondary diagnosis if the encounter is for a related complication or monitoring.
