About 0WQC3ZZ

0WQC3ZZ is the ICD-10-PCS code for a repair procedure on the mediastinum using a percutaneous approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

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 0WQ03ZZ (head), 0WQ23ZZ (face), 0WQ33ZZ (oral cavity and throat), 0WQ43ZZ (upper jaw), 0WQ53ZZ (lower jaw), 0WQ63ZZ (neck) and 6 more.

The same procedure with a different approach is coded 0WQC0ZZ (open) and 0WQC4ZZ (percutaneous endoscopic).

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.
