ICD-9-CM procedure code (retired)
21.03 — Control of epistaxis by cauterization (and packing)
About ICD-9-CM 21.03
21.03 is an ICD-9-CM procedure code for control of epistaxis by cauterization (and packing). 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 10 ICD-10-PCS codes, such as 095K0ZZ (Destruction of Nasal Mucosa and Soft Tissue, Open Approach), 095K0ZZ (Destruction of Nasal Mucosa and Soft Tissue, Open Approach) and 095K3ZZ (Destruction of Nasal Mucosa and Soft Tissue, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
