About 00WV42Z

00WV42Z is the ICD-10-PCS code for a revision procedure on the spinal cord using a percutaneous endoscopic approach with monitoring 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 chordotomy and other operations on spinal cord and spinal canal structures, the ICD-9-CM procedure titles it maps to (03.29 and 03.99).

For a different body part, codes include 00W042Z (brain), 00W642Z (cerebral ventricle), 00WE42Z (cranial nerve) and 00WU42Z (spinal canal).

The same procedure with a different approach is coded 00WV02Z (open), 00WV32Z (percutaneous) and 00WVX2Z (external).

With a different device, use 00WV40Z (drainage device), 00WV43Z (infusion device), 00WV47Z (autologous tissue substitute), 00WV4JZ (synthetic substitute), 00WV4KZ (nonautologous tissue substitute), 00WV4MZ (neurostimulator lead) and 1 more.

It is an operating-room procedure in the MS-DRG logic for DRG 028 (Spinal Procedures with MCC), DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), DRG 030 (Spinal Procedures without CC/MCC), DRG 423 (Other Hepatobiliary or Pancreas O.R. Procedures with MCC), DRG 424 (Other Hepatobiliary or Pancreas O.R. Procedures with CC) and DRG 425 (Other Hepatobiliary or Pancreas O.R. Procedures without CC/MCC), under the surgical categories “Spinal Procedures”, “Other Hepatobiliary or Pancreas O.R. Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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