About ICD-9-CM 39.28
39.28 is an ICD-9-CM procedure code for Extracranial-intracranial (EC-IC) vascular bypass. 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 20 ICD-10-PCS codes, such as 031H09G (Bypass Right Common Carotid Artery to Intracranial Artery with Autologous Venous Tissue, Open Approach), 031H0AG (Bypass Right Common Carotid Artery to Intracranial Artery with Autologous Arterial Tissue, Open Approach) and 031H0JG (Bypass Right Common Carotid Artery to Intracranial Artery with Synthetic Substitute, Open Approach). All of these are approximate matches, so review the record to pick the right one.
