About 0W9F4ZX

0W9F4ZX is the ICD-10-PCS code for a drainage procedure on the abdominal 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 abdominal wall or umbilicus, the ICD-9-CM procedure title it maps to (54.22).

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 0W9F0ZX (open) and 0W9F3ZX (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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