About 00HE02Z
00HE02Z is the ICD-10-PCS code for a insertion procedure on the cranial nerve using an open approach with monitoring 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 00H002Z (brain), 00H602Z (cerebral ventricle), 00HU02Z (spinal canal) and 00HV02Z (spinal cord).
The same procedure with a different approach is coded 00HE32Z (percutaneous) and 00HE42Z (percutaneous endoscopic).
With a different device, use 00HE01Z (radioactive element), 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 has been valid since ICD-10-PCS took effect on October 1, 2015.
