Athscl autologous artery CABG with refractory ang pctrs

This code signifies the presence of atherosclerosis specifically affecting an autologous artery bypass graft (a graft taken from the patient's own body) used in a prior coronary artery bypass surgery. The patient is experiencing refractory angina pectoris, meaning their chest pain is persistent and not adequately relieved by standard medical treatment. This indicates a significant and ongoing ischemic burden despite previous revascularization.

Use this code when documentation clearly states atherosclerosis of an autologous coronary artery bypass graft and the patient presents with refractory angina. This typically applies to patients who have undergone CABG and are now experiencing recurrent or persistent angina due to graft failure or disease progression within the graft itself. Supporting documentation should include physician notes detailing the graft type, the presence of atherosclerosis, and the refractory nature of the angina.

• Ensure the documentation specifies an autologous artery graft, not a venous graft or synthetic graft.
• Confirm that the angina is explicitly described as "refractory" or resistant to treatment.
• This code is typically a secondary diagnosis, with the primary diagnosis often related to the underlying coronary artery disease or the specific manifestation of the angina.
