About 0WH03YZ

0WH03YZ is the ICD-10-PCS code for a insertion procedure on the head using a percutaneous 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 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 0WH13YZ (cranial cavity), 0WH23YZ (face), 0WH33YZ (oral cavity and throat), 0WH43YZ (upper jaw), 0WH53YZ (lower jaw), 0WH63YZ (neck) and 16 more.

The same procedure with a different approach is coded 0WH00YZ (open) and 0WH04YZ (percutaneous endoscopic).

With a different device, use 0WH031Z (radioactive element) and 0WH033Z (infusion 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.
