About 01HY3YZ

01HY3YZ is the ICD-10-PCS code for a insertion procedure on the peripheral nerve using a percutaneous approach with other 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).

The same procedure with a different approach is coded 01HY0YZ (open) and 01HY4YZ (percutaneous endoscopic).

With a different device, use 01HY31Z (radioactive element), 01HY32Z (monitoring device) and 01HY3MZ (neurostimulator lead).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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