About 019300Z

019300Z is the ICD-10-PCS code for a drainage procedure on the brachial plexus using an open approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.04).

For a different body part, codes include 019000Z (cervical plexus), 019100Z (cervical nerve), 019200Z (phrenic nerve), 019400Z (ulnar nerve), 019500Z (median nerve), 019600Z (radial nerve) and 16 more.

The same procedure with a different approach is coded 019330Z (percutaneous) and 019340Z (percutaneous endoscopic).

With a different device, use 01930ZZ (no device).

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.
