About ICD-9-CM 21.22
21.22 is an ICD-9-CM procedure code for biopsy 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 14 ICD-10-PCS codes, such as 099K0ZX (Drainage of Nasal Mucosa and Soft Tissue, Open Approach, Diagnostic), 099K3ZX (Drainage of Nasal Mucosa and Soft Tissue, Percutaneous Approach, Diagnostic) and 099K4ZX (Drainage of Nasal Mucosa and Soft Tissue, Percutaneous Endoscopic Approach, Diagnostic).
