Summary & Overview

CPT 15841: Muscle Transfer for Facial Reanimation

CPT code 15841 represents a reconstructive surgical procedure that transfers muscle tissue from a donor site such as the back, chest, abdomen, or thigh to the face to restore appearance and dynamic function in patients with facial nerve paralysis. The procedure is clinically significant because it addresses long-term functional and psychosocial deficits caused by facial paralysis, and it often involves multidisciplinary care, microsurgical technique, and perioperative resource use. Nationally, coverage and utilization of facial reanimation procedures affect surgical practice patterns, facility planning, and specialty reimbursement.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise policy and billing overview, typical sites of service and clinical context, common modifiers and coding considerations (where available), and benchmarking information when data is present. The publication also summarizes clinical indications and procedural scope pertinent to coding and claims submission.

This summary is intended to inform clinicians, coding professionals, and policy stakeholders about the clinical purpose of CPT code 15841, payer landscape, and the kinds of benchmarks and policy updates that influence billing and authorization for facial reanimation muscle transfer procedures.

Billing Code Overview

CPT code 15841 describes a surgical procedure in which the provider removes a piece of muscle tissue from a donor site such as the back, chest, abdomen, or thigh and transfers it to the face to restore more normal appearance and function in a patient with facial nerve paralysis. This procedure is a form of facial reanimation using a free or regional muscle flap to recreate dynamic movement of the paralyzed face.

Service type: Reconstructive facial surgery (muscle transfer for facial reanimation)
Typical site of service: Operating room in an inpatient or outpatient surgical facility, or ambulatory surgery center, depending on clinical complexity and perioperative needs.

Clinical & Coding Specifications

Clinical Context

A 54-year-old patient with long-standing unilateral facial nerve paralysis following acoustic neuroma resection presents for facial reanimation. The reconstructive surgeon plans a free or regional muscle transfer, harvesting a segment of muscle from the thigh (gracilis) or latissimus area and inset to perioral and midface muscles to restore dynamic smile and eye closure. Preoperative evaluation includes facial nerve function assessment, imaging to assess donor and recipient vasculature, anesthesia evaluation, and discussion of staged reconstruction versus single-stage transfer. Intraoperative workflow includes general endotracheal anesthesia, harvesting of the chosen muscle flap, microvascular anastomosis to facial or superficial temporal vessels, coaptation of motor nerve (masseteric or cross-facial nerve graft) to the transferred muscle, inset and contouring to the face, and placement of drains as needed. Postoperative workflow includes monitoring in a post-anesthesia care unit or intensive care setting with flap perfusion checks, pain control, antibiotic prophylaxis, and coordinated physical therapy for neuromuscular retraining over subsequent months. Typical site of service is an inpatient hospital operating room or ambulatory surgical center with microvascular capabilities depending on case complexity. Service type: reconstructive surgical procedure for facial reanimation.
