About 0WH803Z
0WH803Z is the ICD-10-PCS code for a insertion procedure on the chest wall 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 chest wall, the ICD-9-CM procedure title it maps to (34.01).
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 0WH833Z (percutaneous) and 0WH843Z (percutaneous endoscopic).
With a different device, use 0WH801Z (radioactive element) and 0WH80YZ (other 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.
