About 019K4ZX

019K4ZX is the ICD-10-PCS code for a drainage procedure on the head and neck sympathetic nerve using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of sympathetic nerve or ganglion, the ICD-9-CM procedure title it maps to (05.11).

For a different body part, codes include 01904ZX (cervical plexus), 01914ZX (cervical nerve), 01924ZX (phrenic nerve), 01934ZX (brachial plexus), 01944ZX (ulnar nerve), 01954ZX (median nerve) and 16 more.

The same procedure with a different approach is coded 019K0ZX (open) and 019K3ZX (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) and DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), under the surgical category “Peripheral, Cranial Nerve and Other Nervous System Procedures”.

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