About 0NRQ37Z

0NRQ37Z is the ICD-10-PCS code for a replacement procedure on the left orbit 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 orbitotomy with bone flap, the ICD-9-CM procedure title it maps to (16.01).

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 0NRQ07Z (open) and 0NRQ47Z (percutaneous endoscopic).

With a different device, use 0NRQ3JZ (synthetic substitute) and 0NRQ3KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 113 (Orbital Procedures with CC/MCC), DRG 114 (Orbital Procedures without CC/MCC), 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) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Orbital Procedures”, “Other Ear, Nose, Mouth and Throat 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.
