About ICD-9-CM 21.06

21.06 is an ICD-9-CM procedure code for control of epistaxis by ligation of the external carotid artery. 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 12 ICD-10-PCS codes, such as 03LM0CZ (Occlusion of Right External Carotid Artery with Extraluminal Device, Open Approach), 03LM0ZZ (Occlusion of Right External Carotid Artery, Open Approach) and 03LM3CZ (Occlusion of Right External Carotid Artery with Extraluminal Device, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
