About 0W9F4ZZ

0W9F4ZZ is the ICD-10-PCS code for a drainage procedure on the abdominal wall using a percutaneous endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to percutaneous abdominal drainage, the ICD-9-CM procedure title it maps to (54.91).

For a different body part, codes include 0W904ZZ (head), 0W914ZZ (cranial cavity), 0W924ZZ (face), 0W934ZZ (oral cavity and throat), 0W944ZZ (upper jaw), 0W954ZZ (lower jaw) and 13 more.

The same procedure with a different approach is coded 0W9F0ZZ (open) and 0W9F3ZZ (percutaneous).

With a different device, use 0W9F40Z (drainage 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.
