About 0NWW47Z

0NWW47Z is the ICD-10-PCS code for a revision procedure on the facial bone using a percutaneous endoscopic approach with autologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

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 0NW047Z (skull) and 0NWB47Z (nasal bone).

The same procedure with a different approach is coded 0NWW07Z (open), 0NWW37Z (percutaneous) and 0NWWX7Z (external).

With a different device, use 0NWW40Z (drainage device), 0NWW44Z (internal fixation device), 0NWW45Z (external fixation device), 0NWW4JZ (synthetic substitute), 0NWW4KZ (nonautologous tissue substitute) and 0NWW4MZ (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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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