About ICD-9-CM 04.19

04.19 is an ICD-9-CM procedure code for other diagnostic procedures on cranial and peripheral nerves and ganglia. 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 4 ICD-10-PCS codes, such as 00JE0ZZ (Inspection of Cranial Nerve, Open Approach), 00JE4ZZ (Inspection of Cranial Nerve, Percutaneous Endoscopic Approach) and 01JY0ZZ (Inspection of Peripheral Nerve, Open Approach). All of these are approximate matches, so review the record to pick the right one.
