About 00HE01Z

00HE01Z is the ICD-10-PCS code for a insertion procedure on the cranial nerve using an open approach with radioactive element. 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.

For a different body part, codes include 00H001Z (brain), 00H601Z (cerebral ventricle), 00HU01Z (spinal canal) and 00HV01Z (spinal cord).

The same procedure with a different approach is coded 00HE31Z (percutaneous) and 00HE41Z (percutaneous endoscopic).

With a different device, use 00HE02Z (monitoring device), 00HE03Z (infusion 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 was added in FY2021, effective October 1, 2020.
