About 0WHC01Z

0WHC01Z is the ICD-10-PCS code for a insertion procedure on the mediastinum using an open approach with radioactive element. 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 implantation or insertion of radioactive elements, the ICD-9-CM procedure title it maps to (92.27).

For a different body part, codes include 0WH001Z (head), 0WH101Z (cranial cavity), 0WH201Z (face), 0WH301Z (oral cavity and throat), 0WH401Z (upper jaw), 0WH501Z (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WHC31Z (percutaneous) and 0WHC41Z (percutaneous endoscopic).

With a different device, use 0WHC03Z (infusion device), 0WHC0GZ (defibrillator lead) and 0WHC0YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Circulatory System O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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