About ICD-9-CM 18.6
18.6 is an ICD-9-CM procedure code for reconstruction of external auditory canal. 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 44 ICD-10-PCS codes, such as 09R007Z (Replacement of Right External Ear with Autologous Tissue Substitute, Open Approach), 09R00JZ (Replacement of Right External Ear with Synthetic Substitute, Open Approach) and 09R00KZ (Replacement of Right External Ear with Nonautologous Tissue Substitute, Open Approach). All of these are approximate matches, so review the record to pick the right one.
