About 0WPH4YZ

0WPH4YZ is the ICD-10-PCS code for a removal procedure on the retroperitoneum using a percutaneous endoscopic approach with other device. In ICD-10-PCS, removal means taking out or off a device from a body part.

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 0WP04YZ (head), 0WP14YZ (cranial cavity), 0WP24YZ (face), 0WP44YZ (upper jaw), 0WP54YZ (lower jaw), 0WP64YZ (neck) and 15 more.

The same procedure with a different approach is coded 0WPH0YZ (open) and 0WPH3YZ (percutaneous).

With a different device, use 0WPH40Z (drainage device), 0WPH41Z (radioactive element) and 0WPH43Z (infusion 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.
