What This Code Means

This code describes a condition where fatty deposits have built up in a coronary artery bypass graft made from the patient's own artery, causing chest pain or discomfort of a type other than the most common forms. The narrowing of this bypass graft reduces blood flow to the heart muscle.

Coding Tips

• •Verify documentation specifies the graft type is autologous artery (not vein or synthetic) and confirm the specific type of angina pectoris present to ensure accurate code selection
• •This code requires documentation of both the atherosclerosis of the bypass graft AND the angina pectoris; do not code if only graft disease or only angina is documented without both conditions

Clinical Significance

This code identifies atherosclerosis of an autologous artery coronary bypass graft with angina that is documented but does not fit the specific categories of unstable, vasospastic, or refractory. This typically includes stable exertional angina or angina equivalent presentations in patients with arterial graft disease. Proper classification helps guide treatment decisions specific to arterial graft pathology.

Documentation Requirements

• ✓History of CABG with autologous arterial graft documented
• ✓Evidence of atherosclerotic disease within the arterial bypass graft
• ✓Documentation of angina symptoms with characterization that excludes unstable, vasospastic, and refractory patterns
• ✓Functional classification of angina if documented (Canadian Cardiovascular Society classification)
• ✓Provider statement linking the angina to the graft atherosclerosis
