Summary & Overview
CPT 64771: Severance or Removal of Other Cranial Nerves
CPT code 64771 denotes surgical severing or removal of cranial nerves not otherwise specified in the CPT code set. This is a specialized neurosurgical procedure used in rare or complex clinical scenarios where a cranial nerve must be intentionally transected or excised. Nationally, the code is relevant for hospitals and neurosurgical practices managing advanced cranial neuropathies, tumors, or intractable pain conditions where other treatments are infeasible.
Key payers in the national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical settings for use, along with a summary of payer coverage scope. The publication provides benchmarks where available, notes on coding specificity and documentation expectations, and outlines the clinical scenarios that commonly justify use of this code.
The report is intended for billing professionals, neurosurgeons, hospital revenue leaders, and policy analysts seeking clear guidance on when 64771 applies and how it fits within broader surgical coding for cranial nerve procedures. Data not available in the input is indicated where applicable.
Billing Code Overview
CPT code 64771 describes the severing or removal of other cranial nerves not listed elsewhere in CPT®. This procedure involves deliberate transection or excision of cranial nerve tissue when clinically indicated.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with refractory cranial neuropathic pain, debilitating synkinesis, or a tumor invading a lesser cranial nerve (for example the glossopharyngeal or hypoglossal nerve) in whom conservative therapy and targeted neurolysis have failed or are not indicated. A neurosurgeon or otolaryngologist evaluates the patient preoperatively with focused neurologic and cranial nerve examinations, imaging (MRI or CT with contrast to identify lesion involvement), and pain/function scoring. The procedure, 64771, is performed in an operating room under general anesthesia. Intraoperative nerve monitoring may be used. The surgeon identifies and severs or removes the specific cranial nerve not listed elsewhere in CPT (for example posterior branch of a lower cranial nerve affected by tumor or severe pain). Postoperative workflow includes recovery monitoring for airway and swallowing, pain control, and targeted rehabilitation (speech/swallow therapy) when applicable. Discharge planning and documentation address expected neurologic deficits and follow-up imaging or clinic visits to assess symptom control and complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or complexity substantially exceeds usual for 64771 due to extensive dissection or unexpected findings. |
