00HE0MZInsertion of Neurostimulator Lead into Cranial Nerve, Open Approach

00HE0MZ is the ICD-10-PCS code for a insertion procedure on the cranial nerve using an open 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 peripheral neurostimulator lead(s), the ICD-9-CM procedure title it maps to (04.92).

For a different body part, codes include 00H00MZ (brain), 00H60MZ (cerebral ventricle), 00HU0MZ (spinal canal) and 00HV0MZ (spinal cord).

The same procedure with a different approach is coded 00HE3MZ (percutaneous) and 00HE4MZ (percutaneous endoscopic).

With a different device, use 00HE01Z (radioactive element), 00HE02Z (monitoring device), 00HE03Z (infusion device) and 00HE0YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Vascular Procedures” and 7 more.

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