About 00933ZX

00933ZX is the ICD-10-PCS code for a drainage procedure on the epidural space, intracranial using a percutaneous 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 00903ZX (brain), 00913ZX (cerebral meninges), 00923ZX (dura mater), 00943ZX (subdural space, intracranial), 00953ZX (subarachnoid space, intracranial), 00963ZX (cerebral ventricle) and 24 more.

The same procedure with a different approach is coded 00930ZX (open) and 00934ZX (percutaneous endoscopic).

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.
