About 018L0ZZ

018L0ZZ is the ICD-10-PCS code for a division procedure on the thoracic sympathetic 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 sympathetic nerve or ganglion, the ICD-9-CM procedure title it maps to (05.0).

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 018L3ZZ (percutaneous) and 018L4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 040 (Peripheral, Cranial Nerve and Other Nervous System Procedures with MCC), DRG 041 (Peripheral, Cranial Nerve and Other Nervous System Procedures with CC or Peripheral Neurostimulator), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 361 (Other Circulatory System O.R. Procedures with MCC) and DRG 362 (Other Circulatory System O.R. Procedures without MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures” and “Other Circulatory System O.R. Procedures”.

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