About 00RS0KZ
00RS0KZ is the ICD-10-PCS code for a replacement procedure on the hypoglossal nerve using an open approach with nonautologous 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 00R10KZ (cerebral meninges), 00R20KZ (dura mater), 00R60KZ (cerebral ventricle), 00RF0KZ (olfactory nerve), 00RG0KZ (optic nerve), 00RH0KZ (oculomotor nerve) and 9 more.
The same procedure with a different approach is coded 00RS4KZ (percutaneous endoscopic).
With a different device, use 00RS07Z (autologous tissue substitute) and 00RS0JZ (synthetic 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.
