Summary & Overview

CPT 15731: Forehead Flap Reconstruction for Face or Scalp

CPT code 15731 covers forehead flap reconstruction in which a forehead skin flap, with intact vascular supply, is rotated to repair injuries or open wounds of the face or scalp. This reconstructive technique is a core procedure in facial and scalp trauma, oncology reconstruction, and complex wound care. Nationally, this code matters for surgical departments, plastic and reconstructive surgeons, and payers because it reflects a resource-intensive procedure that carries implications for perioperative management, site-of-service determination, and payment policy.

Key payers considered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical-context briefing, coding and billing considerations, and benchmark-oriented summaries for these major payers. The publication highlights expected sites of service, typical clinical indications derived from the procedure description, and common operational factors that influence utilization and billing.

Readers will learn where 15731 fits within reconstructive service lines, how it is typically delivered (operating room or surgical center), and which national payers are primary stakeholders. Data not available in the input for items such as associated taxonomies, specific ICD-10 pairings, and payer-specific payment benchmarks is noted where applicable.

Billing Code Overview

CPT code 15731 describes a surgical procedure in which the provider creates a forehead skin flap and transfers it, with its vascular supply intact, to repair an injury or cover an open wound on the face or scalp. This procedure involves rotating the flap to cover the facial or scalp defect and is performed to restore tissue coverage, protect underlying structures, and optimize cosmetic and functional outcomes.

Service type: Reconstructive surgical flap procedure
Typical site of service: Operating room or surgical suite, often in an inpatient or outpatient surgical center depending on case complexity

Clinical & Coding Specifications

Clinical Context

A 58-year-old male presents to the emergency department after a motor vehicle collision with a full-thickness avulsive defect of the central forehead and adjacent scalp with exposed subcutaneous tissue. After initial trauma assessment, he is taken to the operating room by a plastic and reconstructive surgeon. Under general anesthesia, the surgeon designs a rotational forehead flap based on the supratrochlear vascular pedicle, elevates the flap with its intact vascular supply, rotates the flap to cover the facial/scalp defect, and secures it with sutures. The donor site on the forehead is closed primarily or with a skin graft as needed. Postoperative care includes flap monitoring for perfusion, wound care, and follow-up visits for suture removal and possible staged revision.
