About 0W984ZX

0W984ZX is the ICD-10-PCS code for a drainage procedure on the chest wall using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of chest wall, the ICD-9-CM procedure title it maps to (34.23).

For a different body part, codes include 0W904ZX (head), 0W914ZX (cranial cavity), 0W924ZX (face), 0W934ZX (oral cavity and throat), 0W944ZX (upper jaw), 0W954ZX (lower jaw) and 13 more.

The same procedure with a different approach is coded 0W980ZX (open) and 0W983ZX (percutaneous).

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.
