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.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the physician’s professional portion separate from technical services if applicable in a split-bill arrangement.
`50`	Bilateral procedure	Use when identical forehead flaps are performed on both sides of the face in separate anatomic defects (rare for `15731`).
`51`	Multiple procedures	Use when `15731` is billed on the same day as additional distinct procedures; append to secondary procedures per payer rules.
`52`	Reduced services	Use when the procedure is intentionally partially reduced or not completed as originally planned.
`53`	Discontinued procedure	Use when the flap procedure is started but discontinued due to unforeseen circumstances.
`54`	Surgical care only	Use when reporting only the surgical portion and another practitioner provides pre/postoperative care.
`55`	Postoperative management only	Use when reporting only postoperative care after another surgeon performed the operation.
`58`	Staged or related procedure or service by the same physician during the postoperative period	Use for planned staged flap revisions or secondary procedures related to initial `15731` performed during global period.
`59`	Distinct procedural service	Use when reporting a separate, distinct procedure on the same day that is not typically bundled with `15731` (requires documentation of distinctness).
`62`	Two surgeons	Use when two surgeons of different specialties work together as primary surgeons performing separate portions of the procedure.
`76`	Repeat procedure by same physician	Use when the identical procedure is repeated by the same physician subsequent to the original service on the same day.
`77`	Repeat procedure by another physician	Use when the identical procedure is repeated by a different physician on the same day.
`78`	Unplanned return to the operating room for a related procedure during the postoperative period	Use when the patient returns to the OR for management of a complication of the flap.
`79`	Unrelated procedure or service by same physician during the postoperative period	Use when an unrelated surgical procedure is performed during the global period.

Taxonomy Code	Specialty	Notes
`208800000X`	Plastic and Reconstructive Surgery	Primary specialty performing forehead rotational flap procedures.

`2086S0100X`	General Surgery	May perform flap reconstruction in trauma centers or when subspecialty not available.
`207L00000X`	Head and Neck Surgery	Involved when defects cross facial cosmetic and functional subunits.
`261Q00000X`	Dermatology	Performs forehead flap reconstruction primarily for skin cancer defects involving nasal/facial reconstruction.
