About 00DM4ZZ

00DM4ZZ is the ICD-10-PCS code for a extraction procedure on the facial nerve using a percutaneous endoscopic approach. In ICD-10-PCS, extraction means pulling or stripping out or off all or a portion of a body part by the use of force.

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

For a different body part, codes include 00D04ZZ (brain), 00D14ZZ (cerebral meninges), 00D24ZZ (dura mater), 00D74ZZ (cerebral hemisphere), 00DC4ZZ (cerebellum), 00DF4ZZ (olfactory nerve) and 11 more.

The same procedure with a different approach is coded 00DM0ZZ (open) and 00DM3ZZ (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.
