About 00H004Z

00H004Z is the ICD-10-PCS code for a insertion procedure on the brain using an open approach with radioactive element, cesium-131 collagen implant. 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 insertion of radioactive elements, the ICD-9-CM procedure title it maps to (92.27).

With a different device, use 00H001Z (radioactive element), 00H002Z (monitoring device), 00H003Z (infusion device), 00H005Z (radioactive element, palladium-103 collagen implant), 00H00MZ (neurostimulator lead) and 00H00YZ (other device).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator) and DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC), under the surgical category “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”.

It was added in FY2018, effective October 1, 2017.
