CPT code 64788 denotes the surgical excision of a tumor located just under the skin that is growing along a cutaneous nerve. Nationally, this code captures procedures that address subcutaneous neoplasms with direct nerve involvement—cases that can involve delicate dissection to remove the lesion while preserving nerve function where possible. The code matters for surgical specialties, outpatient surgical centers, and insurers because it reflects a targeted procedure with implications for operative setting, anesthesia, and post‑operative management.

Key payers discussed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the procedural focus of the code. The publication summarizes benchmarking elements and coverage considerations at a national level, highlights common billing modifiers associated with surgical services (listed separately), and outlines what clinicians and billing teams need to know about coding specificity for nerve‑associated subcutaneous tumor excision. If specific payer policies or national reimbursement benchmarks are available, those elements are presented in dedicated sections; if not, the report notes data limitations. This resource is intended to orient clinicians, coding staff, and policy analysts to the clinical and billing identity of CPT code 64788.
