About 0WUC4KZ

0WUC4KZ is the ICD-10-PCS code for a supplement procedure on the mediastinum using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to other operations on thorax, the ICD-9-CM procedure title it maps to (34.99).

For a different body part, codes include 0WU04KZ (head), 0WU24KZ (face), 0WU44KZ (upper jaw), 0WU54KZ (lower jaw), 0WU64KZ (neck), 0WU84KZ (chest wall) and 5 more.

The same procedure with a different approach is coded 0WUC0KZ (open).

With a different device, use 0WUC47Z (autologous tissue substitute) and 0WUC4JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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