About 00XR0ZM

00XR0ZM is the ICD-10-PCS code for a transfer procedure on the accessory nerve using an open approach (qualifier: facial nerve). In ICD-10-PCS, transfer means moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part.

In plain terms, this corresponds to transposition of cranial and peripheral nerves and Accessory-facial anastomosis, the ICD-9-CM procedure titles it maps to (04.6 and 04.72).

For a different body part, codes include 00XF0ZM (olfactory nerve), 00XG0ZM (optic nerve), 00XH0ZM (oculomotor nerve), 00XJ0ZM (trochlear nerve), 00XK0ZM (trigeminal nerve), 00XL0ZM (abducens nerve) and 5 more.

The same procedure with a different approach is coded 00XR4ZM (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.
