About 008P3ZZ

008P3ZZ is the ICD-10-PCS code for a division procedure on the glossopharyngeal 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 glossopharyngeal nerve, the ICD-9-CM procedure title it maps to (29.92).

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 008P0ZZ (open) and 008P4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 023 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis with MCC or Antineoplastic Implant or Epilepsy with Neurostimulator), DRG 024 (Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis without MCC), DRG 025 (Craniotomy and Endovascular Intracranial Procedures with MCC), DRG 026 (Craniotomy and Endovascular Intracranial Procedures with CC), DRG 027 (Craniotomy and Endovascular Intracranial Procedures without CC/MCC) and DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), under the surgical categories “Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis”, “Craniotomy and endovascular intracranial procedures” and “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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