About 009U4ZZ

009U4ZZ is the ICD-10-PCS code for a drainage procedure on the spinal canal 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 spinal tap, the ICD-9-CM procedure title it maps to (03.31).

For a different body part, codes include 00904ZZ (brain), 00914ZZ (cerebral meninges), 00924ZZ (dura mater), 00934ZZ (epidural space, intracranial), 00944ZZ (subdural space, intracranial), 00954ZZ (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 009U0ZZ (open) and 009U3ZZ (percutaneous).

With a different device, use 009U40Z (drainage device).

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.
