About 0YWB40Z

0YWB40Z is the ICD-10-PCS code for a revision procedure on the left lower extremity using a percutaneous endoscopic approach with drainage 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 0YW940Z (right lower extremity).

The same procedure with a different approach is coded 0YWB00Z (open), 0YWB30Z (percutaneous) and 0YWBX0Z (external).

With a different device, use 0YWB43Z (infusion device), 0YWB47Z (autologous tissue substitute), 0YWB4JZ (synthetic substitute), 0YWB4KZ (nonautologous tissue substitute) and 0YWB4YZ (other device).

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.
