About 00WE30Z

00WE30Z is the ICD-10-PCS code for a revision procedure on the cranial nerve using a percutaneous approach with drainage device. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 00W030Z (brain), 00W630Z (cerebral ventricle), 00WU30Z (spinal canal) and 00WV30Z (spinal cord).

The same procedure with a different approach is coded 00WE00Z (open), 00WE40Z (percutaneous endoscopic) and 00WEX0Z (external).

With a different device, use 00WE32Z (monitoring device), 00WE33Z (infusion device), 00WE37Z (autologous tissue substitute), 00WE3MZ (neurostimulator lead) and 00WE3YZ (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.
