About 01PY4YZ
01PY4YZ is the ICD-10-PCS code for a removal procedure on the peripheral nerve using a percutaneous endoscopic approach with other device. In ICD-10-PCS, removal means taking out or off a device from 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 01PY0YZ (open) and 01PY3YZ (percutaneous).
With a different device, use 01PY40Z (drainage device), 01PY42Z (monitoring device), 01PY47Z (autologous tissue substitute) and 01PY4MZ (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.
