ICD-10-PCS Code For Trigeminal Nerve: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 00XK includes procedures performed to transfer all or a portion of the trigeminal nerve to another location. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of the trigeminal nerve is moved to assume or restore function of sensory or motor components of the face. Accurate coding within the ICD-10-PCS 00XK group is essential for proper inpatient reimbursement, as it captures the specific transfer procedure performed and determines appropriate case mix and payment.

Trigeminal Nerve Transfer Procedure Overview

Procedures in this group involve moving, without removing, all or part of the trigeminal nerve to a new location so that it can assume or restore function for facial sensation or motor components innervated by the nerve. These procedures target the central nervous system and cranial nerves and are coded in the inpatient setting using the International Classification of Diseases, Tenth Revision, Procedure Coding System. Accurate coding matters because it documents the specific transfer operation and supports appropriate inpatient case mix assignment and reimbursement.

When to Use

Use a code from this group when the documented procedure specifically describes transferring the trigeminal nerve or a defined portion of it to another anatomical site without removal. Do not use these codes for resections, repairs, or other operations that are not classified as transfer.

Typical Clinical Scenarios

A 45-year-old patient with severe trigeminal nerve injury after skull base trauma has loss of facial sensation and corneal protective reflex on the affected side. After evaluation, the surgical team elects to move a viable segment of the trigeminal nerve and reattach it to the facial nerve distribution to restore corneal sensation and blink-related input; the operation is performed via an open cranial approach. A transfer procedure is chosen because nerve grafting alone would not restore the sensory-motor conduit needed for corneal protection. Typical codes: 00XK0ZM
A 62-year-old patient with long-standing trigeminal neuropathy and progressive atrophy of masticatory muscles elects a planned reconstructive nerve transfer to reinnervate trigeminal motor targets and improve chewing function. The multidisciplinary team schedules a percutaneous endoscopic procedure to move a portion of the trigeminal nerve to the trigeminal motor branch to assume lost function while minimizing soft-tissue disruption and hospitalization time. Typical codes: 00XK4ZK
A patient who previously underwent a nerve transfer presents with incomplete functional recovery months later; scar tethering at the transfer site is believed to be limiting reinnervation. The surgical team performs an open revision transfer, repositioning and reallocating the trigeminal nerve portion to a different cranial nerve target — the hypoglossal nerve — to improve motor input and salvage function. Typical codes: 00XK0ZS
