About 00JE4ZZ

00JE4ZZ is the ICD-10-PCS code for a inspection procedure on the cranial nerve using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on cranial and peripheral nerves and ganglia, the ICD-9-CM procedure title it maps to (04.19).

For a different body part, codes include 00J04ZZ (brain), 00JU4ZZ (spinal canal) and 00JV4ZZ (spinal cord).

The same procedure with a different approach is coded 00JE0ZZ (open) and 00JE3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator) and DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), under the surgical category “Peripheral, Cranial Nerve and Other Nervous System Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
