About 00HU4MZ

00HU4MZ is the ICD-10-PCS code for a insertion procedure on the spinal canal using a percutaneous endoscopic approach with neurostimulator lead. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.

In plain terms, this corresponds to implantation or replacement of spinal neurostimulator lead(s), the ICD-9-CM procedure title it maps to (03.93).

For a different body part, codes include 00H04MZ (brain), 00H64MZ (cerebral ventricle), 00HE4MZ (cranial nerve) and 00HV4MZ (spinal cord).

The same procedure with a different approach is coded 00HU0MZ (open) and 00HU3MZ (percutaneous).

With a different device, use 00HU41Z (radioactive element), 00HU42Z (monitoring device), 00HU43Z (infusion device) and 00HU4YZ (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”, “Other Kidney and Urinary Tract Procedures” and 7 more.

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