About 009T40Z
009T40Z is the ICD-10-PCS code for a drainage procedure on the spinal meninges using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to other exploration and decompression of spinal canal, the ICD-9-CM procedure title it maps to (03.09).
For a different body part, codes include 009040Z (brain), 009140Z (cerebral meninges), 009240Z (dura mater), 009340Z (epidural space, intracranial), 009440Z (subdural space, intracranial), 009540Z (subarachnoid space, intracranial) and 24 more.
The same procedure with a different approach is coded 009T00Z (open) and 009T30Z (percutaneous).
With a different device, use 009T4ZZ (no device).
It is an operating-room procedure in the MS-DRG logic for DRG 028 (Spinal Procedures with MCC), DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), DRG 030 (Spinal Procedures without CC/MCC), DRG 518 (Back and Neck Procedures Except Spinal Fusion with MCC or Disc Device or Neurostimulator), DRG 519 (Back and Neck Procedures Except Spinal Fusion with CC) and DRG 520 (Back and Neck Procedures Except Spinal Fusion without CC/MCC), under the surgical categories “Spinal Procedures”, “Back and Neck Procedures Except Spinal Fusion or Disc Device or Neurostimulator”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
