About 00RG47Z

00RG47Z is the ICD-10-PCS code for a replacement procedure on the optic nerve using a percutaneous endoscopic 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 cranial or peripheral nerve graft, the ICD-9-CM procedure title it maps to (04.5).

For a different body part, codes include 00R147Z (cerebral meninges), 00R247Z (dura mater), 00R647Z (cerebral ventricle), 00RF47Z (olfactory nerve), 00RH47Z (oculomotor nerve), 00RJ47Z (trochlear nerve) and 9 more.

The same procedure with a different approach is coded 00RG07Z (open).

With a different device, use 00RG4JZ (synthetic substitute) and 00RG4KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System 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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It was added in FY2018, effective October 1, 2017.
