About 00PE42Z

00PE42Z is the ICD-10-PCS code for a removal procedure on the cranial nerve using a percutaneous endoscopic approach with monitoring device. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to other incision of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.04).

For a different body part, codes include 00P042Z (brain), 00P642Z (cerebral ventricle), 00PU42Z (spinal canal) and 00PV42Z (spinal cord).

The same procedure with a different approach is coded 00PE02Z (open), 00PE32Z (percutaneous) and 00PEX2Z (external).

With a different device, use 00PE40Z (drainage device), 00PE43Z (infusion device), 00PE47Z (autologous tissue substitute), 00PE4MZ (neurostimulator lead) and 00PE4YZ (other device).

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.
