Summary & Overview
CPT 15840: Facial Reanimation Soft-Tissue Transfer
CPT code 15840 represents a reconstructive surgical procedure that transfers subcutaneous tissue from a donor site (commonly the thigh) to the face to restore appearance and function in patients with facial nerve paralysis. Nationally, this code captures complex facial reanimation efforts that can involve microsurgical or pedicled tissue transfer and is relevant to plastic and reconstructive surgery, otolaryngology, and head and neck practices.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The coverage and coding interpretation for this procedure affect authorization requirements, facility-site designation (inpatient vs outpatient), and bundling with other reconstructive or nerve procedures.
Readers will learn the clinical context for use of the code, typical sites of service, and how the code is positioned within surgical reconstructive services. The publication provides benchmarks and policy-relevant considerations for payers and providers, including payer coverage patterns, common billing challenges, and documentation elements that support medical necessity. Data not available in the input is noted where applicable; the summary focuses on nationally applicable information for clinicians, coding staff, and policy analysts involved in facial reanimation procedures.
Billing Code Overview
CPT code 15840 describes a surgical procedure in which the provider harvests a piece of tissue from beneath the skin at a donor site (for example, the thigh) and transposes it to the face to restore a more normal appearance for a patient with facial nerve paralysis. This procedure is reconstructive in nature and involves transfer of autologous soft tissue to address facial contour and symmetry deficits caused by paralysis.
-
Service type: Reconstructive soft-tissue transfer (free or pedicled tissue transfer for facial reanimation)
-
Typical site of service: Operating room, inpatient or outpatient surgical facility depending on clinical complexity and patient needs
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with unilateral facial nerve paralysis due to chronic facial nerve injury, Bell palsy sequelae, tumor resection, or traumatic nerve disruption resulting in significant facial asymmetry and loss of dynamic movement. The patient has failed conservative therapy (physical therapy, neuromuscular retraining) and is evaluated by a multidisciplinary team including a facial plastic surgeon and a reconstructive microsurgeon.
Preoperative workup includes detailed facial nerve assessment, photography, consent for free tissue transfer or regional muscle/fascia transfer, and planning of donor site (for example, a portion of thigh tissue or fascia). On the day of surgery, the patient undergoes general anesthesia in an operating room at an ambulatory surgical center or hospital inpatient surgical unit. The provider harvests a flap or tissue segment from a donor site (such as the thigh), performs microsurgical or local inset to the paralyzed facial region, and secures vascular or nerve anastomoses as indicated to restore contour and, when applicable, function. Postoperative care includes monitoring in PACU or ICU for microvascular viability, pain control, wound care, and staged follow-up for potential secondary revisions and physical therapy for reinnervation or functional retraining.
Coding Specifications
| Modifier | Description | When to Use |

00 | Default/No modifier specified | Rarely used; not typically appended when a specific modifier applies |
11 | Office or other outpatient visit | Use when billing reflects the standard or default performance of the procedure by the primary reporting provider |
22 | Increased procedural services | Use when work required is substantially greater than typically required (extensive dissection, prolonged operative time) |
26 | Professional component | Use when only the professional (surgeon) component is billed separate from technical component |
50 | Bilateral procedure | Use when identical procedure is performed bilaterally on the face (rare for unilateral facial reanimation) |
51 | Multiple procedures | Use when 15840 is billed with other distinct surgical procedures during same session |
52 | Reduced services | Use when the procedure is partially reduced or not completed as originally planned |
53 | Discontinued procedure | Use when procedure is terminated due to extenuating circumstances or patient condition |
62 | Two surgeons | Use when two surgeons of different specialties work together as primary surgeons on separate portions of the procedure |
63 | Procedure performed on infants less than 4 kg | Use when applicable to an infant patient meeting weight criteria |
66 | Surgical team (multiple surgeons) | Use when a surgical team approach is billed for complex reconstruction requiring multiple surgeons |
78 | Unplanned return to OR following initial procedure | Use for related return to the operating room for a complication of the original procedure |
80 | Assistant surgeon required | Use when an assistant surgeon participates and assistant fees are billed |
TC | Technical component | Use when only the technical component (facility resources, equipment) is billed by an entity separate from the surgeon |
