About ICD-9-CM 36.13
36.13 is an ICD-9-CM procedure code for (Aorto)coronary bypass of three coronary arteries. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.
The CMS General Equivalence Mappings translate it to 10 ICD-10-PCS codes, such as 021208W (Bypass Coronary Artery, Three Arteries from Aorta with Zooplastic Tissue, Open Approach), 021209W (Bypass Coronary Artery, Three Arteries from Aorta with Autologous Venous Tissue, Open Approach) and 02120AW (Bypass Coronary Artery, Three Arteries from Aorta with Autologous Arterial Tissue, Open Approach). All of these are approximate matches, so review the record to pick the right one.
