About 00NX3ZZ

00NX3ZZ is the ICD-10-PCS code for a release procedure on the thoracic spinal cord using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to other exploration and decompression of spinal canal and lysis of adhesions of spinal cord and nerve roots, the ICD-9-CM procedure titles it maps to (03.09 and 03.6).

For a different body part, codes include 00N03ZZ (brain), 00N13ZZ (cerebral meninges), 00N23ZZ (dura mater), 00N63ZZ (cerebral ventricle), 00N73ZZ (cerebral hemisphere), 00N83ZZ (basal ganglia) and 20 more.

The same procedure with a different approach is coded 00NX0ZZ (open) and 00NX4ZZ (percutaneous endoscopic).

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.
