About 0WHH01Z

0WHH01Z is the ICD-10-PCS code for a insertion procedure on the retroperitoneum 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 0WHH31Z (percutaneous) and 0WHH41Z (percutaneous endoscopic).

With a different device, use 0WHH03Z (infusion device) and 0WHH0YZ (other device).

It is an operating-room procedure in the MS-DRG logic for 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), DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), DRG 673 (Other Kidney and Urinary Tract Procedures with MCC), DRG 674 (Other Kidney and Urinary Tract Procedures with CC) and DRG 675 (Other Kidney and Urinary Tract Procedures without CC/MCC), under the surgical categories “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other Kidney and Urinary Tract Procedures” and “Other O.R. Procedures for Injuries”.

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