About 0WHP03Z

0WHP03Z is the ICD-10-PCS code for a insertion procedure on the gastrointestinal tract using an open approach with infusion 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 0WH003Z (head), 0WH103Z (cranial cavity), 0WH203Z (face), 0WH303Z (oral cavity and throat), 0WH403Z (upper jaw), 0WH503Z (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHP33Z (percutaneous), 0WHP43Z (percutaneous endoscopic), 0WHP73Z (via natural or artificial opening) and 0WHP83Z (via natural or artificial opening endoscopic).

With a different device, use 0WHP01Z (radioactive element) and 0WHP0YZ (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.
