About 0WWC30Z

0WWC30Z is the ICD-10-PCS code for a revision procedure on the mediastinum using a percutaneous 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 incision of mediastinum, the ICD-9-CM procedure title it maps to (34.1).

The same procedure with a different approach is coded 0WWC00Z (open), 0WWC40Z (percutaneous endoscopic) and 0WWCX0Z (external).
