About 00WU3MZ

00WU3MZ is the ICD-10-PCS code for a revision procedure on the spinal canal using a percutaneous approach with neurostimulator lead. 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 00W03MZ (brain), 00W63MZ (cerebral ventricle), 00WE3MZ (cranial nerve) and 00WV3MZ (spinal cord).

The same procedure with a different approach is coded 00WU0MZ (open), 00WU4MZ (percutaneous endoscopic) and 00WUXMZ (external).

With a different device, use 00WU30Z (drainage device), 00WU32Z (monitoring device), 00WU33Z (infusion device), 00WU3JZ (synthetic substitute) and 00WU3YZ (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.
