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

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

Glossopharyngeal Nerve Transfer Procedure Overview

Procedures in this ICD-10-PCS code group involve transferring all or a portion of the glossopharyngeal nerve to another location to assume or support the function of a different nerve or neural structure. These procedures target the central nervous system and cranial nerves and are coded in the Medical and Surgical section. Accurate coding is important for documenting the specific transfer operation and ensuring appropriate inpatient reimbursement based on the complexity of the neural procedure.

When to Use

Use a code from this group when surgical transfer of the glossopharyngeal nerve is performed to restore or substitute neural function in another structure. These codes apply when tissue is moved without taking it out of the body to assume the role of the recipient neural target.

Typical Clinical Scenarios

An adult patient presents electively for reconstruction of facial motor function after a traumatic avulsion of the facial nerve where local donor nerves are unavailable; a planned transfer of a segment of the glossopharyngeal nerve to reinnervate the facial nerve is performed to restore voluntary facial movement over time. Typical codes: 00XP0ZM, 00XP4ZM
An elderly patient with progressive hypoglossal nerve palsy secondary to skull base tumor undergoes an inpatient, staged salvage procedure to reestablish tongue motor function by transferring part of the glossopharyngeal nerve to the hypoglossal nerve when tumor resection results in loss of native hypoglossal input. Typical codes: 00XP0ZS, 00XP4ZS
A young adult is admitted urgently for revision of a prior cranial nerve repair after failed trigeminal reinnervation with persistent neuropathic pain and sensory deficit; during the inpatient revision the glossopharyngeal nerve is mobilized and transferred to the trigeminal nerve to provide alternative afferent input. Typical codes: 00XP0ZK, 00XP4ZK
