About 00HU4YZ

00HU4YZ is the ICD-10-PCS code for a insertion procedure on the spinal canal using a percutaneous endoscopic approach with other device. 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 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 00H04YZ (brain), 00H64YZ (cerebral ventricle), 00HE4YZ (cranial nerve) and 00HV4YZ (spinal cord).

The same procedure with a different approach is coded 00HU0YZ (open) and 00HU3YZ (percutaneous).

With a different device, use 00HU41Z (radioactive element), 00HU42Z (monitoring device), 00HU43Z (infusion device) and 00HU4MZ (neurostimulator lead).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
