About 0DWW4KZ

0DWW4KZ is the ICD-10-PCS code for a revision procedure on the peritoneum using a percutaneous endoscopic approach with nonautologous tissue substitute. 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 peritoneum, the ICD-9-CM procedure title it maps to (54.95).

For a different body part, codes include 0DW04KZ (upper intestinal tract), 0DW64KZ (stomach), 0DW84KZ (small intestine), 0DWD4KZ (lower intestinal tract), 0DWE4KZ (large intestine), 0DWU4KZ (omentum) and 1 more.

The same procedure with a different approach is coded 0DWW0KZ (open) and 0DWW3KZ (percutaneous).

With a different device, use 0DWW40Z (drainage device), 0DWW47Z (autologous tissue substitute) and 0DWW4JZ (synthetic 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) and DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), under the surgical category “Other Digestive System O.R. Procedures”.

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