About 009U4ZX
009U4ZX is the ICD-10-PCS code for a drainage procedure on the spinal canal 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 spinal tap and biopsy of spinal cord or spinal meninges, the ICD-9-CM procedure titles it maps to (03.31 and 03.32).
For a different body part, codes include 00904ZX (brain), 00914ZX (cerebral meninges), 00924ZX (dura mater), 00934ZX (epidural space, intracranial), 00944ZX (subdural space, intracranial), 00954ZX (subarachnoid space, intracranial) and 24 more.
The same procedure with a different approach is coded 009U0ZX (open) and 009U3ZX (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.
