About 00HE3YZ

00HE3YZ is the ICD-10-PCS code for a insertion procedure on the cranial nerve using a percutaneous 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 incision of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.04).

For a different body part, codes include 00H03YZ (brain), 00H63YZ (cerebral ventricle), 00HU3YZ (spinal canal) and 00HV3YZ (spinal cord).

The same procedure with a different approach is coded 00HE0YZ (open) and 00HE4YZ (percutaneous endoscopic).

With a different device, use 00HE31Z (radioactive element), 00HE32Z (monitoring device), 00HE33Z (infusion device) and 00HE3MZ (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.
