About 01903ZZ

01903ZZ is the ICD-10-PCS code for a drainage procedure on the cervical plexus using a percutaneous approach. 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 miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 01913ZZ (cervical nerve), 01923ZZ (phrenic nerve), 01933ZZ (brachial plexus), 01943ZZ (ulnar nerve), 01953ZZ (median nerve), 01963ZZ (radial nerve) and 16 more.

The same procedure with a different approach is coded 01900ZZ (open) and 01904ZZ (percutaneous endoscopic).

With a different device, use 019030Z (drainage device).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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