The CMS General Equivalence Mappings translate it to 10 ICD-10-PCS codes, such as 021008W (Bypass Coronary Artery, One Artery from Aorta with Zooplastic Tissue, Open Approach), 021009W (Bypass Coronary Artery, One Artery from Aorta with Autologous Venous Tissue, Open Approach) and 02100AW (Bypass Coronary Artery, One Artery from Aorta with Autologous Arterial Tissue, Open Approach). All of these are approximate matches, so review the record to pick the right one.
