About 009P3ZX

009P3ZX is the ICD-10-PCS code for a drainage procedure on the glossopharyngeal nerve 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 cranial or peripheral nerve or ganglion, the ICD-9-CM procedure title it maps to (04.11).

For a different body part, codes include 00903ZX (brain), 00913ZX (cerebral meninges), 00923ZX (dura mater), 00933ZX (epidural space, intracranial), 00943ZX (subdural space, intracranial), 00953ZX (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 009P0ZX (open) and 009P4ZX (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.
