About 01B54ZX

01B54ZX is the ICD-10-PCS code for a excision procedure on the median nerve using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 01B04ZX (cervical plexus), 01B14ZX (cervical nerve), 01B24ZX (phrenic nerve), 01B34ZX (brachial plexus), 01B44ZX (ulnar nerve), 01B64ZX (radial nerve) and 16 more.

The same procedure with a different approach is coded 01B50ZX (open) and 01B53ZX (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.
