About 00954ZX

00954ZX is the ICD-10-PCS code for a drainage procedure on the subarachnoid space, intracranial using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to closed [percutaneous] [needle] biopsy of cerebral meninges, the ICD-9-CM procedure title it maps to (01.11).

For a different body part, codes include 00904ZX (brain), 00914ZX (cerebral meninges), 00924ZX (dura mater), 00934ZX (epidural space, intracranial), 00944ZX (subdural space, intracranial), 00964ZX (cerebral ventricle) and 24 more.

The same procedure with a different approach is coded 00950ZX (open) and 00953ZX (percutaneous).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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