About 00U23KZ

00U23KZ is the ICD-10-PCS code for a supplement procedure on the dura mater using a percutaneous approach with nonautologous tissue substitute. In ICD-10-PCS, supplement means putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part.

In plain terms, this corresponds to other repair of cerebral meninges, the ICD-9-CM procedure title it maps to (02.12).

For a different body part, codes include 00U13KZ (cerebral meninges), 00U63KZ (cerebral ventricle), 00UF3KZ (olfactory nerve), 00UG3KZ (optic nerve), 00UH3KZ (oculomotor nerve), 00UJ3KZ (trochlear nerve) and 9 more.

The same procedure with a different approach is coded 00U20KZ (open) and 00U24KZ (percutaneous endoscopic).

With a different device, use 00U237Z (autologous tissue substitute) and 00U23JZ (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC), DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), DRG 026 (Craniotomy and Endovascular Intracranial Procedures with CC), DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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