About 015L4ZZ

015L4ZZ is the ICD-10-PCS code for a destruction procedure on the thoracic sympathetic nerve using a percutaneous endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to Periarterial sympathectomy and other sympathectomy and ganglionectomy, the ICD-9-CM procedure titles it maps to (05.25 and 05.29).

For a different body part, codes include 01504ZZ (cervical plexus), 01514ZZ (cervical nerve), 01524ZZ (phrenic nerve), 01534ZZ (brachial plexus), 01544ZZ (ulnar nerve), 01554ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 015L0ZZ (open) and 015L3ZZ (percutaneous).

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.
