About 0WWP7YZ

0WWP7YZ is the ICD-10-PCS code for a revision procedure on the gastrointestinal tract using a via natural or artificial opening 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 other operations of abdominal region, the ICD-9-CM procedure title it maps to (54.99).

For a different body part, codes include 0WWQ7YZ (respiratory tract) and 0WWR7YZ (genitourinary tract).

The same procedure with a different approach is coded 0WWP0YZ (open), 0WWP3YZ (percutaneous), 0WWP4YZ (percutaneous endoscopic), 0WWP8YZ (via natural or artificial opening endoscopic) and 0WWPXYZ (external).

With a different device, use 0WWP71Z (radioactive element) and 0WWP73Z (infusion device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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