About 00BP4ZZ

00BP4ZZ is the ICD-10-PCS code for a excision procedure on the glossopharyngeal nerve using a percutaneous endoscopic approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to other cranial or peripheral ganglionectomy and other excision or avulsion of cranial and peripheral nerves, the ICD-9-CM procedure titles it maps to (04.06 and 04.07).

For a different body part, codes include 00B04ZZ (brain), 00B14ZZ (cerebral meninges), 00B24ZZ (dura mater), 00B64ZZ (cerebral ventricle), 00B74ZZ (cerebral hemisphere), 00B84ZZ (basal ganglia) and 20 more.

The same procedure with a different approach is coded 00BP0ZZ (open) and 00BP3ZZ (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), 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 Musculoskeletal System and Connective Tissue O.R. Procedures” and 1 more.

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