About 00924ZZ

00924ZZ is the ICD-10-PCS code for a drainage procedure on the dura mater using a percutaneous endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to intracranial ventricular shunt or anastomosis, the ICD-9-CM procedure title it maps to (02.22).

For a different body part, codes include 00904ZZ (brain), 00914ZZ (cerebral meninges), 00934ZZ (epidural space, intracranial), 00944ZZ (subdural space, intracranial), 00954ZZ (subarachnoid space, intracranial), 00964ZZ (cerebral ventricle) and 24 more.

The same procedure with a different approach is coded 00920ZZ (open) and 00923ZZ (percutaneous).

With a different device, use 009240Z (drainage device).

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) and DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis” and “Craniotomy and endovascular intracranial procedures”.

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