About 0WWF0YZ

0WWF0YZ is the ICD-10-PCS code for a revision procedure on the abdominal wall using an open approach with other 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 abdominal wall, the ICD-9-CM procedure title it maps to (54.0).

For a different body part, codes include 0WW00YZ (head), 0WW10YZ (cranial cavity), 0WW20YZ (face), 0WW40YZ (upper jaw), 0WW50YZ (lower jaw), 0WW60YZ (neck) and 15 more.

The same procedure with a different approach is coded 0WWF3YZ (percutaneous), 0WWF4YZ (percutaneous endoscopic) and 0WWFXYZ (external).

With a different device, use 0WWF00Z (drainage device), 0WWF01Z (radioactive element), 0WWF03Z (infusion device), 0WWF07Z (autologous tissue substitute), 0WWF0JZ (synthetic substitute) and 0WWF0KZ (nonautologous tissue substitute).

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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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