About 01PY02Z

01PY02Z is the ICD-10-PCS code for a removal procedure on the peripheral nerve using an open approach with monitoring 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 and other operations on sympathetic nerves or ganglia, the ICD-9-CM procedure titles it maps to (04.04 and 05.89).

The same procedure with a different approach is coded 01PY32Z (percutaneous), 01PY42Z (percutaneous endoscopic) and 01PYX2Z (external).

With a different device, use 01PY00Z (drainage device), 01PY07Z (autologous tissue substitute), 01PY0MZ (neurostimulator lead) and 01PY0YZ (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.
