About 0WCC3ZZ

0WCC3ZZ is the ICD-10-PCS code for a extirpation procedure on the mediastinum using a percutaneous approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to incision of mediastinum, the ICD-9-CM procedure title it maps to (34.1).

The same procedure with a different approach is coded 0WCC0ZZ (open), 0WCC4ZZ (percutaneous endoscopic) and 0WCCXZZ (external).

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 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Other Respiratory System O.R. Procedures”, “Other Circulatory System O.R.
