CPT Code Overview

CPT code 15004 is used to report the surgical preparation or creation of a recipient site by excision of open wounds, burn eschar, or scar, including subcutaneous tissues, or incisional release of scar contracture. This procedure is performed on sensitive and complex anatomical areas such as the face, scalp, eyelids, mouth, neck, ears, orbits, genitalia, hands, feet, and multiple digits. The code specifically applies to the first 100 square centimeters or 1% of body area in infants and children. The typical site of service for this procedure is an outpatient hospital setting, reflecting its use in specialized surgical care for patients requiring skin replacement or preparation for grafting.

Clinical & Coding Specifications

Clinical Context

A pediatric patient presents to the outpatient hospital with a burn injury involving less than 10% of the body surface, or with hypertrophic scarring and contracture affecting the face, hands, or feet. The clinical workflow involves surgical preparation of the recipient site by excising burn eschar, open wounds, or scar tissue, including subcutaneous tissues. This procedure is performed to facilitate subsequent skin grafting or other reconstructive interventions. The provider, typically a plastic surgeon specializing in head and neck (otolaryngology), assesses the area, marks the excision boundaries, and performs the surgical preparation for the first 100 sq cm or 1% of body area in infants and children.

Coding Specifications

Modifier 51: Used when multiple procedures are performed during the same operative session. Indicates that more than one procedure was completed.
Modifier 59: Used to identify procedures/services that are distinct or independent from other services performed on the same day. Indicates a distinct procedural service.
