About 0WWH30Z

0WWH30Z is the ICD-10-PCS code for a revision procedure on the retroperitoneum using a percutaneous approach with drainage 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 peritoneum, the ICD-9-CM procedure title it maps to (54.95).

For a different body part, codes include 0WW030Z (head), 0WW130Z (cranial cavity), 0WW230Z (face), 0WW430Z (upper jaw), 0WW530Z (lower jaw), 0WW630Z (neck) and 12 more.

The same procedure with a different approach is coded 0WWH00Z (open), 0WWH40Z (percutaneous endoscopic) and 0WWHX0Z (external).

With a different device, use 0WWH31Z (radioactive element), 0WWH33Z (infusion device) and 0WWH3YZ (other device).

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.
