About 00WU02Z

00WU02Z is the ICD-10-PCS code for a revision procedure on the spinal canal using an open 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 operations on spinal cord and spinal canal structures, the ICD-9-CM procedure title it maps to (03.99).

For a different body part, codes include 00W002Z (brain), 00W602Z (cerebral ventricle), 00WE02Z (cranial nerve) and 00WV02Z (spinal cord).

The same procedure with a different approach is coded 00WU32Z (percutaneous), 00WU42Z (percutaneous endoscopic) and 00WUX2Z (external).

With a different device, use 00WU00Z (drainage device), 00WU03Z (infusion device), 00WU0JZ (synthetic substitute), 00WU0MZ (neurostimulator lead) and 00WU0YZ (other device).

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 518 (Back and Neck Procedures Except Spinal Fusion with MCC or Disc Device or Neurostimulator), DRG 519 (Back and Neck Procedures Except Spinal Fusion with CC) and DRG 520 (Back and Neck Procedures Except Spinal Fusion without CC/MCC), under the surgical categories “Spinal Procedures”, “Back and Neck Procedures Except Spinal Fusion or Disc Device or Neurostimulator”, “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.
