About 01XC4ZB

01XC4ZB is the ICD-10-PCS code for a transfer procedure on the pudendal nerve using a percutaneous endoscopic approach (qualifier: lumbar nerve). In ICD-10-PCS, transfer means moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part.

In plain terms, this corresponds to other anastomosis of cranial or peripheral nerve, the ICD-9-CM procedure title it maps to (04.74).

For a different body part, codes include 01XB4ZB (lumbar nerve).

The same procedure with a different approach is coded 01XC0ZB (open).

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.
