About 01544ZZ

01544ZZ is the ICD-10-PCS code for a destruction procedure on the ulnar nerve using a percutaneous endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to destruction of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.2).

For a different body part, codes include 01504ZZ (cervical plexus), 01514ZZ (cervical nerve), 01524ZZ (phrenic nerve), 01534ZZ (brachial plexus), 01554ZZ (median nerve), 01564ZZ (radial nerve) and 16 more.

The same procedure with a different approach is coded 01540ZZ (open) and 01543ZZ (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.
