About 0WH341Z

0WH341Z is the ICD-10-PCS code for a insertion procedure on the oral cavity and throat using a percutaneous endoscopic 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 0WH041Z (head), 0WH141Z (cranial cavity), 0WH241Z (face), 0WH441Z (upper jaw), 0WH541Z (lower jaw), 0WH641Z (neck) and 16 more.

The same procedure with a different approach is coded 0WH301Z (open) and 0WH331Z (percutaneous).

With a different device, use 0WH343Z (infusion device) and 0WH34YZ (other device).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. 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 “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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