About 01924ZX

01924ZX is the ICD-10-PCS code for a drainage procedure on the phrenic 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 closed [percutaneous] [needle] biopsy of cranial or peripheral nerve or ganglion, the ICD-9-CM procedure title it maps to (04.11).

For a different body part, codes include 01904ZX (cervical plexus), 01914ZX (cervical nerve), 01934ZX (brachial plexus), 01944ZX (ulnar nerve), 01954ZX (median nerve), 01964ZX (radial nerve) and 16 more.

The same procedure with a different approach is coded 01920ZX (open) and 01923ZX (percutaneous).

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.
