About 0WHG0YZ

0WHG0YZ is the ICD-10-PCS code for a insertion procedure on the peritoneal cavity using an open approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of 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 0WH00YZ (head), 0WH10YZ (cranial cavity), 0WH20YZ (face), 0WH30YZ (oral cavity and throat), 0WH40YZ (upper jaw), 0WH50YZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHG3YZ (percutaneous) and 0WHG4YZ (percutaneous endoscopic).

With a different device, use 0WHG01Z (radioactive element) and 0WHG03Z (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.
