About 019900Z

019900Z is the ICD-10-PCS code for a drainage procedure on the lumbar 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), 019300Z (brachial plexus), 019400Z (ulnar nerve), 019500Z (median nerve) and 16 more.

The same procedure with a different approach is coded 019930Z (percutaneous) and 019940Z (percutaneous endoscopic).

With a different device, use 01990ZZ (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.
