About ICD-9-CM 21.1
21.1 is an ICD-9-CM procedure code for incision of nose. 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 58 ICD-10-PCS codes, such as 099K00Z (Drainage of Nasal Mucosa and Soft Tissue with Drainage Device, Open Approach), 099K0ZZ (Drainage of Nasal Mucosa and Soft Tissue, Open Approach) and 099K30Z (Drainage of Nasal Mucosa and Soft Tissue with Drainage Device, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
