About 008W4ZZ

008W4ZZ is the ICD-10-PCS code for a division procedure on the cervical spinal cord using a percutaneous endoscopic approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to percutaneous chordotomy, the ICD-9-CM procedure title it maps to (03.21).

For a different body part, codes include 00804ZZ (brain), 00874ZZ (cerebral hemisphere), 00884ZZ (basal ganglia), 008F4ZZ (olfactory nerve), 008G4ZZ (optic nerve), 008H4ZZ (oculomotor nerve) and 11 more.

The same procedure with a different approach is coded 008W0ZZ (open) and 008W3ZZ (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 423 (Other Hepatobiliary or Pancreas O.R. Procedures with MCC), DRG 424 (Other Hepatobiliary or Pancreas O.R. Procedures with CC) and DRG 425 (Other Hepatobiliary or Pancreas O.R. Procedures without CC/MCC), under the surgical categories “Spinal Procedures”, “Other Hepatobiliary or Pancreas O.R. Procedures”, “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.
