About 008K3ZZ

008K3ZZ is the ICD-10-PCS code for a division procedure on the trigeminal nerve using a percutaneous approach. In ICD-10-PCS, division means cutting into a body part, without draining fluids and/or gases from the body part, in order to separate or transect a body part.

In plain terms, this corresponds to division of trigeminal nerve, the ICD-9-CM procedure title it maps to (04.02).

For a different body part, codes include 00803ZZ (brain), 00873ZZ (cerebral hemisphere), 00883ZZ (basal ganglia), 008F3ZZ (olfactory nerve), 008G3ZZ (optic nerve), 008H3ZZ (oculomotor nerve) and 11 more.

The same procedure with a different approach is coded 008K0ZZ (open) and 008K4ZZ (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), DRG 042 (Peripheral, Cranial Nerve and Other Nervous System Procedures without CC/MCC), DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
