About 00BT4ZX

00BT4ZX is the ICD-10-PCS code for a excision procedure on the spinal meninges using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to biopsy of spinal cord or spinal meninges, the ICD-9-CM procedure title it maps to (03.32).

For a different body part, codes include 00B04ZX (brain), 00B14ZX (cerebral meninges), 00B24ZX (dura mater), 00B64ZX (cerebral ventricle), 00B74ZX (cerebral hemisphere), 00B84ZX (basal ganglia) and 20 more.

The same procedure with a different approach is coded 00BT0ZX (open) and 00BT3ZX (percutaneous).

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 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
