About 0WWP01Z

0WWP01Z is the ICD-10-PCS code for a revision procedure on the gastrointestinal tract using an open approach with radioactive element. 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 0WW001Z (head), 0WW101Z (cranial cavity), 0WW201Z (face), 0WW401Z (upper jaw), 0WW501Z (lower jaw), 0WW601Z (neck) and 15 more.

The same procedure with a different approach is coded 0WWP31Z (percutaneous), 0WWP41Z (percutaneous endoscopic), 0WWP71Z (via natural or artificial opening), 0WWP81Z (via natural or artificial opening endoscopic) and 0WWPX1Z (external).

With a different device, use 0WWP03Z (infusion device) and 0WWP0YZ (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.
