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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 00XN includes procedures performed to transfer neural tissue in the acoustic nerve. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of the acoustic nerve is moved to another location to take over the function of another nerve or neural structure. Accurate coding within the ICD-10-PCS 00XN group is essential for proper inpatient reimbursement, as it captures the specific procedure performed and supports clinical documentation accuracy.

Acoustic Nerve Transfer Procedure Overview

Procedures in this ICD-10-PCS group involve transferring all or a portion of the acoustic nerve to another location to assume or augment neural function. These procedures target the central nervous system and cranial nerves and involve microsurgical techniques to reposition neural tissue without removing it. Accurate ICD-10-PCS coding is important for inpatient documentation and reimbursement because it captures the specific transfer operation and anatomical site involved.

When to Use

Use a code from this group when an operative transfer of all or a portion of the acoustic nerve is performed without removal of the nerve. These codes apply when the surgical intent is to reposition neural tissue so it can take over the function of another nerve or neural structure.

Typical Clinical Scenarios

An adult patient with unilateral facial paralysis after a vestibular schwannoma resection presents electively for nerve reanimation using a nerve transfer to restore facial motor function; inpatient microsurgical transfer of a segment of the acoustic nerve is performed to reinnervate the facial nerve to improve oral commissure movement and eye closure. Typical codes: 00XN0ZM, 00XN4ZM
A pediatric patient born with congenital hypoglossal nerve agenesis is admitted for a planned reconstructive procedure to restore tongue motor function; surgeons transfer a portion of the acoustic nerve to assume hypoglossal function and facilitate swallowing and speech development, requiring inpatient postoperative monitoring. Typical codes: 00XN0ZS, 00XN4ZS
An adult develops progressive trigeminal neuropathic pain after trauma with loss of trigeminal function and undergoes a revision procedure where neural tissue from the acoustic nerve is transferred to the trigeminal nerve to salvage sensory function and reduce complications from prior interventions; the patient requires inpatient care for the complex microsurgical transfer and recovery. Typical codes: 00XN0ZK, 00XN4ZK
