About 0NRM37Z

0NRM37Z is the ICD-10-PCS code for a replacement procedure on the right zygomatic bone using a percutaneous approach with autologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to bone graft to facial bone, the ICD-9-CM procedure title it maps to (76.91).

For a different body part, codes include 0NR037Z (skull), 0NR137Z (frontal bone), 0NR337Z (right parietal bone), 0NR437Z (left parietal bone), 0NR537Z (right temporal bone), 0NR637Z (left temporal bone) and 16 more.

The same procedure with a different approach is coded 0NRM07Z (open) and 0NRM47Z (percutaneous endoscopic).

With a different device, use 0NRM3JZ (synthetic substitute) and 0NRM3KZ (nonautologous tissue substitute).

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.
