About 01WYXMZ
01WYXMZ is the ICD-10-PCS code for a revision procedure on the peripheral nerve using an external approach with neurostimulator lead. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.
In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).
The same procedure with a different approach is coded 01WY0MZ (open), 01WY3MZ (percutaneous) and 01WY4MZ (percutaneous endoscopic).
With a different device, use 01WYX0Z (drainage device), 01WYX2Z (monitoring device) and 01WYX7Z (autologous tissue substitute).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
