About ICD-9-CM 04.03
04.03 is an ICD-9-CM procedure code for division or crushing of other cranial and peripheral nerves. 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 69 ICD-10-PCS codes, such as 008F0ZZ (Division of Olfactory Nerve, Open Approach), 008F3ZZ (Division of Olfactory Nerve, Percutaneous Approach) and 008F4ZZ (Division of Olfactory Nerve, Percutaneous Endoscopic Approach). All of these are approximate matches, so review the record to pick the right one.
