About 01NP4ZZ

01NP4ZZ is the ICD-10-PCS code for a release procedure on the sacral sympathetic nerve using a percutaneous endoscopic approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to repair of sympathetic nerve or ganglion, the ICD-9-CM procedure title it maps to (05.81).

For a different body part, codes include 01N04ZZ (cervical plexus), 01N14ZZ (cervical nerve), 01N24ZZ (phrenic nerve), 01N34ZZ (brachial plexus), 01N44ZZ (ulnar nerve), 01N54ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 01NP0ZZ (open) and 01NP3ZZ (percutaneous).

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.
