CPT 64868 Facial-Hypoglossal Anastomosis Reimbursement | OpenPayer

Summary & Overview

CPT 64868: Facial-to-Hypoglossal Nerve Anastomosis for Facial Reanimation

CPT code 64868 denotes a surgical nerve transfer that connects the facial nerve to the hypoglossal nerve to restore facial motor function after complete facial nerve loss from tumor resection or traumatic injury. This reconstructive microsurgical procedure is clinically significant because it addresses long-term facial paralysis, improving symmetry and voluntary movement and reducing functional disability and psychosocial impact for affected patients. Nationally, availability of the procedure is concentrated in specialty centers with microsurgery expertise, and its coding impacts how reconstructive head and neck services are classified and reimbursed.

Key payers reviewed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context and service setting, benchmarking considerations for utilization and reimbursement, common billing modifiers associated with complex surgical services, and policy and coverage themes that affect access to reconstructive nerve procedures. The report also outlines coding relationships and typical sites of service to aid billing teams, compliance officers, and policy analysts in understanding how CPT code 64868 fits within surgical service lines and payer frameworks.

Billing Code Overview

CPT code 64868 describes a surgical procedure that creates a nerve anastomosis between the facial nerve and the hypoglossal nerve to restore facial motor function after facial nerve loss from tumor resection or traumatic injury. The procedure re-routes motor fibers to reanimate facial musculature and address facial paralysis resulting from disruption of the native facial nerve.

Service type: Reconstructive peripheral nerve surgery (nerve transfer/anastomosis)
Typical site of service: Inpatient or outpatient operating room setting under general anesthesia; often performed in tertiary care centers or specialty head and neck surgery units where microsurgical nerve repair and reconstruction are available.

Clinical & Coding Specifications

Clinical Context

A 48-year-old patient presents with complete unilateral facial paralysis following surgical resection of a vestibular schwannoma that required sacrifice of the facial nerve. After initial observation and conservative therapies (eye protection, physical therapy) for 6–12 months with no return of facial motor function, the patient is evaluated for reanimation surgery. The multidisciplinary workflow includes preoperative facial nerve and hypoglossal nerve assessment by a neurosurgeon or head and neck surgeon, counseling by a plastic/reconstructive surgeon regarding expected outcomes and tongue morbidity, preoperative imaging to confirm anatomy and prior surgical changes, and baseline facial function documentation (House-Brackmann scale). In the operating room under general anesthesia, the surgeon performs a hypoglossal-facial nerve anastomosis (64868) to restore facial motor function. Postoperative care includes monitoring for airway or swallowing compromise, tongue weakness assessment, facial rehabilitation, and scheduled follow-up visits to document progressive reinnervation and functional improvement.
