About 00CT4ZZ

00CT4ZZ is the ICD-10-PCS code for a extirpation procedure on the spinal meninges using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to removal of foreign body from spinal canal, the ICD-9-CM procedure title it maps to (03.01).

For a different body part, codes include 00C04ZZ (brain), 00C14ZZ (cerebral meninges), 00C24ZZ (dura mater), 00C34ZZ (epidural space, intracranial), 00C44ZZ (subdural space, intracranial), 00C54ZZ (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 00CT0ZZ (open) and 00CT3ZZ (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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Spinal Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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