About 01BL3ZZ

01BL3ZZ is the ICD-10-PCS code for a excision procedure on the thoracic sympathetic nerve using a percutaneous approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

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 01B03ZZ (cervical plexus), 01B13ZZ (cervical nerve), 01B23ZZ (phrenic nerve), 01B33ZZ (brachial plexus), 01B43ZZ (ulnar nerve), 01B53ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 01BL0ZZ (open) and 01BL4ZZ (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.
