About 0YWB4YZ

0YWB4YZ is the ICD-10-PCS code for a revision procedure on the left lower extremity using a percutaneous endoscopic approach with other device. 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 incision of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.09).

For a different body part, codes include 0YW94YZ (right lower extremity).

The same procedure with a different approach is coded 0YWB0YZ (open), 0YWB3YZ (percutaneous) and 0YWBXYZ (external).

With a different device, use 0YWB40Z (drainage device), 0YWB43Z (infusion device), 0YWB47Z (autologous tissue substitute), 0YWB4JZ (synthetic substitute) and 0YWB4KZ (nonautologous tissue substitute).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical category “Other Skin, Subcutaneous Tissue and Breast Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
