About 0WH403Z

0WH403Z is the ICD-10-PCS code for a insertion procedure on the upper jaw 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 other incision of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.09).

For a different body part, codes include 0WH003Z (head), 0WH103Z (cranial cavity), 0WH203Z (face), 0WH303Z (oral cavity and throat), 0WH503Z (lower jaw), 0WH603Z (neck) and 16 more.

The same procedure with a different approach is coded 0WH433Z (percutaneous) and 0WH443Z (percutaneous endoscopic).

With a different device, use 0WH401Z (radioactive element) and 0WH40YZ (other device).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical category “Other Skin, Subcutaneous Tissue and Breast Procedures”.

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