About 00HE03Z

00HE03Z is the ICD-10-PCS code for a insertion procedure on the cranial nerve using an open approach with infusion 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 00H003Z (brain), 00H603Z (cerebral ventricle), 00HU03Z (spinal canal) and 00HV03Z (spinal cord).

The same procedure with a different approach is coded 00HE33Z (percutaneous) and 00HE43Z (percutaneous endoscopic).

With a different device, use 00HE01Z (radioactive element), 00HE02Z (monitoring device), 00HE0MZ (neurostimulator lead) 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) and DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), under the surgical category “Peripheral, Cranial Nerve and Other Nervous System Procedures”.

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