About 0NPW4KZ

0NPW4KZ is the ICD-10-PCS code for a removal procedure on the facial bone using a percutaneous endoscopic approach with nonautologous tissue substitute. In ICD-10-PCS, removal means taking out or off a device from a body part.

In plain terms, this corresponds to other incision of facial bone, the ICD-9-CM procedure title it maps to (76.09).

For a different body part, codes include 0NP04KZ (skull) and 0NPB4KZ (nasal bone).

The same procedure with a different approach is coded 0NPW0KZ (open) and 0NPW3KZ (percutaneous).

With a different device, use 0NPW40Z (drainage device), 0NPW44Z (internal fixation device), 0NPW45Z (external fixation device), 0NPW47Z (autologous tissue substitute), 0NPW4JZ (synthetic substitute) and 0NPW4MZ (bone growth stimulator).

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 495 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with MCC), DRG 496 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur with CC) and DRG 497 (Local Excision and Removal of Internal Fixation Devices Except Hip and Femur without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures” and “Local Excision and Removal of Internal Fixation Devices Except Hip and Femur”.

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