About 01HY41Z

01HY41Z is the ICD-10-PCS code for a insertion procedure on the peripheral nerve using a percutaneous endoscopic 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.

The same procedure with a different approach is coded 01HY01Z (open) and 01HY31Z (percutaneous).

With a different device, use 01HY42Z (monitoring device), 01HY4MZ (neurostimulator lead) and 01HY4YZ (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.
