About 0WH843Z
0WH843Z is the ICD-10-PCS code for a insertion procedure on the chest wall using a percutaneous endoscopic 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 0WH043Z (head), 0WH143Z (cranial cavity), 0WH243Z (face), 0WH343Z (oral cavity and throat), 0WH443Z (upper jaw), 0WH543Z (lower jaw) and 16 more.
The same procedure with a different approach is coded 0WH803Z (open) and 0WH833Z (percutaneous).
With a different device, use 0WH841Z (radioactive element) and 0WH84YZ (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.
