About 00XJ4ZP

00XJ4ZP is the ICD-10-PCS code for a transfer procedure on the trochlear nerve using a percutaneous endoscopic approach (qualifier: glossopharyngeal 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 other anastomosis of cranial or peripheral nerve, the ICD-9-CM procedure titles it maps to (04.6 and 04.74).

For a different body part, codes include 00XF4ZP (olfactory nerve), 00XG4ZP (optic nerve), 00XH4ZP (oculomotor nerve), 00XK4ZP (trigeminal nerve), 00XL4ZP (abducens nerve), 00XM4ZP (facial nerve) and 5 more.

The same procedure with a different approach is coded 00XJ0ZP (open).

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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Peripheral, Cranial Nerve and Other Nervous System Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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