Official Description

Anastomosis; facial-hypoglossal

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 64868 refers to the surgical technique of facial-hypoglossal anastomosis, which is a method used to reconstruct the facial nerve. This procedure is typically indicated for patients who have suffered facial nerve damage, often due to trauma, tumors, or other pathological conditions that impair facial function. The goal of the surgery is to restore facial movement by connecting the hypoglossal nerve, which controls tongue movement, to the facial nerve, thereby allowing for reinnervation of the facial muscles. The surgical approach involves making an incision near the ear, carefully dissecting through various anatomical structures, and identifying the facial nerve at the stylomastoid foramen. The hypoglossal nerve is then located and prepared for anastomosis to the facial nerve, utilizing microsurgical techniques to ensure precision and minimize complications. This procedure is critical for improving the quality of life for patients with facial nerve deficits, as it aims to restore both aesthetic and functional aspects of facial movement.

1. Indications

The facial-hypoglossal anastomosis procedure (CPT® Code 64868) is indicated for patients experiencing facial nerve dysfunction due to various conditions. These may include:

  • Facial Nerve Injury: Trauma or surgical interventions that have resulted in damage to the facial nerve, leading to loss of facial muscle function.
  • Facial Nerve Tumors: Neoplasms affecting the facial nerve that necessitate surgical intervention and subsequent reconstruction.
  • Congenital Facial Nerve Disorders: Conditions present at birth that affect the development and function of the facial nerve.

2. Procedure

The surgical procedure for facial-hypoglossal anastomosis involves several critical steps to ensure successful nerve reconstruction. Each step is performed with precision to facilitate optimal outcomes.

  • Step 1: An incision is made just in front of the auricle of the ear, extending around the ear lobe and along the mandible. This incision allows access to the underlying structures necessary for the procedure.
  • Step 2: A skin flap is elevated to expose the parotid gland. The inferior aspect of the parotid gland is carefully dissected off the sternocleidomastoid muscle to provide a clear view of the facial nerve.
  • Step 3: Dissection continues to the digastric muscle, where the tissue anterior to the tip and superior to the tragus is meticulously dissected to identify the facial nerve as it exits the stylomastoid foramen.
  • Step 4: The facial nerve is dissected to the point of injury or damage and is transected distal to this point to prepare for anastomosis.
  • Step 5: The hypoglossal nerve is located by following the digastric muscle belly toward the hyoid bone. Distal dissection of the hypoglossal nerve is performed until sufficient length is achieved for the anastomosis.
  • Step 6: The hypoglossal nerve is transected distally and transposed to align with the healthy distal segment of the facial nerve.
  • Step 7: Finally, the nerve ends are anastomosed using a perineural or epineural technique, ensuring a secure connection that promotes nerve regeneration.

3. Post-Procedure

After the facial-hypoglossal anastomosis procedure, patients typically require careful monitoring and follow-up care. Post-operative care may include pain management, wound care, and physical therapy to facilitate recovery and improve facial function. Patients are advised to avoid strenuous activities during the initial healing phase. The expected recovery period can vary, with gradual improvement in facial movement as the nerves regenerate. Regular follow-up appointments are essential to assess the healing process and the effectiveness of the nerve reconstruction.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
