ICD-9-CM procedure code (retired)
89.15 — Other nonoperative neurologic function tests
About ICD-9-CM 89.15
89.15 is an ICD-9-CM procedure code for other nonoperative neurologic function tests. 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 19 ICD-10-PCS codes, such as 4A00X2Z (Measurement of Central Nervous Conductivity, External Approach), 4A01329 (Measurement of Peripheral Nervous Conductivity, Sensory, Percutaneous Approach) and 4A0132B (Measurement of Peripheral Nervous Conductivity, Motor, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
