About 0W040KZ

0W040KZ is the ICD-10-PCS code for a alteration procedure on the upper jaw using an open approach with nonautologous tissue substitute. In ICD-10-PCS, alteration means modifying the anatomic structure of a body part without affecting the function of the body part.

In plain terms, this corresponds to augmentation genioplasty, the ICD-9-CM procedure title it maps to (76.68).

For a different body part, codes include 0W000KZ (head), 0W020KZ (face), 0W050KZ (lower jaw), 0W060KZ (neck), 0W080KZ (chest wall), 0W0F0KZ (abdominal wall) and 4 more.

The same procedure with a different approach is coded 0W043KZ (percutaneous) and 0W044KZ (percutaneous endoscopic).

With a different device, use 0W0407Z (autologous tissue substitute), 0W040JZ (synthetic substitute) and 0W040ZZ (no 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 515 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with MCC), DRG 516 (Other Musculoskeletal System and Connective Tissue O.R. Procedures with CC) and DRG 517 (Other Musculoskeletal System and Connective Tissue O.R. Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Musculoskeletal System and Connective Tissue O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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