About 0W9840Z

0W9840Z is the ICD-10-PCS code for a drainage procedure on the chest wall using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to incision of chest wall, the ICD-9-CM procedure title it maps to (34.01).

For a different body part, codes include 0W9040Z (head), 0W9140Z (cranial cavity), 0W9240Z (face), 0W9340Z (oral cavity and throat), 0W9440Z (upper jaw), 0W9540Z (lower jaw) and 13 more.

The same procedure with a different approach is coded 0W9800Z (open) and 0W9830Z (percutaneous).

With a different device, use 0W984ZZ (no device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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