About 0WH641Z

0WH641Z is the ICD-10-PCS code for a insertion procedure on the neck 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), 0WH341Z (oral cavity and throat), 0WH441Z (upper jaw), 0WH541Z (lower jaw) and 16 more.

The same procedure with a different approach is coded 0WH601Z (open) and 0WH631Z (percutaneous).

With a different device, use 0WH643Z (infusion device) and 0WH64YZ (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 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures” and “Other O.R. Procedures for Injuries”.

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