About 00QK0ZZ

00QK0ZZ is the ICD-10-PCS code for a repair procedure on the trigeminal nerve using an open approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to suture of cranial and peripheral nerves and other neuroplasty, the ICD-9-CM procedure titles it maps to (04.3 and 04.79).

For a different body part, codes include 00Q00ZZ (brain), 00Q10ZZ (cerebral meninges), 00Q20ZZ (dura mater), 00Q60ZZ (cerebral ventricle), 00Q70ZZ (cerebral hemisphere), 00Q80ZZ (basal ganglia) and 20 more.

The same procedure with a different approach is coded 00QK3ZZ (percutaneous) and 00QK4ZZ (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.
