About 0WH84YZ

0WH84YZ is the ICD-10-PCS code for a insertion procedure on the chest wall using a percutaneous endoscopic 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 chest wall, the ICD-9-CM procedure title it maps to (34.01).

For a different body part, codes include 0WH04YZ (head), 0WH14YZ (cranial cavity), 0WH24YZ (face), 0WH34YZ (oral cavity and throat), 0WH44YZ (upper jaw), 0WH54YZ (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WH80YZ (open) and 0WH83YZ (percutaneous).

With a different device, use 0WH841Z (radioactive element) and 0WH843Z (infusion device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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