About ICD-9-CM 21.29

21.29 is an ICD-9-CM procedure code for other diagnostic procedures on 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 3 ICD-10-PCS codes, such as 09JK0ZZ (Inspection of Nasal Mucosa and Soft Tissue, Open Approach), 09JK3ZZ (Inspection of Nasal Mucosa and Soft Tissue, Percutaneous Approach) and 09JK4ZZ (Inspection of Nasal Mucosa and Soft Tissue, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
