About 01810ZZ

01810ZZ is the ICD-10-PCS code for a division procedure on the cervical 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), 01820ZZ (phrenic nerve), 01830ZZ (brachial plexus), 01840ZZ (ulnar nerve), 01850ZZ (median nerve), 01860ZZ (radial nerve) and 16 more.

The same procedure with a different approach is coded 01813ZZ (percutaneous) and 01814ZZ (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.
