About 00CP4ZZ

00CP4ZZ is the ICD-10-PCS code for a extirpation procedure on the glossopharyngeal nerve using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to other incision of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.04).

For a different body part, codes include 00C04ZZ (brain), 00C14ZZ (cerebral meninges), 00C24ZZ (dura mater), 00C34ZZ (epidural space, intracranial), 00C44ZZ (subdural space, intracranial), 00C54ZZ (subarachnoid space, intracranial) and 24 more.

The same procedure with a different approach is coded 00CP0ZZ (open) and 00CP3ZZ (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.
