About 0WH001Z

0WH001Z is the ICD-10-PCS code for a insertion procedure on the head 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 0WH101Z (cranial cavity), 0WH201Z (face), 0WH301Z (oral cavity and throat), 0WH401Z (upper jaw), 0WH501Z (lower jaw), 0WH601Z (neck) and 16 more.

The same procedure with a different approach is coded 0WH031Z (percutaneous) and 0WH041Z (percutaneous endoscopic).

With a different device, use 0WH003Z (infusion device) and 0WH00YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/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 “Peripheral, Cranial Nerve and Other Nervous System Procedures” and “Other O.R. Procedures for Injuries”.

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