About 01NK3ZZ

01NK3ZZ is the ICD-10-PCS code for a release procedure on the head and neck sympathetic nerve using a percutaneous 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 01N03ZZ (cervical plexus), 01N13ZZ (cervical nerve), 01N23ZZ (phrenic nerve), 01N33ZZ (brachial plexus), 01N43ZZ (ulnar nerve), 01N53ZZ (median nerve) and 16 more.

The same procedure with a different approach is coded 01NK0ZZ (open) and 01NK4ZZ (percutaneous endoscopic).

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.
