About 01880ZZ

01880ZZ is the ICD-10-PCS code for a division procedure on the thoracic nerve using an open 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 division of intraspinal nerve root, the ICD-9-CM procedure title it maps to (03.1).

For a different body part, codes include 01800ZZ (cervical plexus), 01810ZZ (cervical nerve), 01820ZZ (phrenic nerve), 01830ZZ (brachial plexus), 01840ZZ (ulnar nerve), 01850ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 01883ZZ (percutaneous) and 01884ZZ (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.
