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

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, and the angina is specifically documented as being due to coronary artery spasm. This indicates a complex cardiac condition involving both graft disease and vasospastic angina in a transplanted heart.

Use this code when documentation clearly indicates atherosclerotic changes within a coronary bypass graft in a transplanted heart. The patient must also present with angina pectoris, and the medical record must explicitly state that the angina is attributed to documented coronary artery spasm. This code is appropriate for post-transplant patients with this specific combination of graft pathology and anginal etiology.

• Ensure documentation explicitly links the angina to "documented spasm" and not just general angina.
• Verify the heart is a "transplanted heart" and not the patient's native heart.
• Distinguish from codes for atherosclerosis of native coronary arteries or bypass grafts without documented spasm.
