Summary & Overview

CPT 21554: Excision of Deep Soft-Tissue Tumor, Neck or Anterior Thorax

CPT code 21554 denotes the excision of a deep soft-tissue tumor measuring 5 cm or larger beneath the fascia of the neck or anterior thorax. This is a major surgical procedure that carries implications for operative planning, resource use, and postoperative care. Nationally, accurate coding of large deep-tissue tumor excisions affects surgical case mix reporting, payment classification, and quality measurement related to oncologic and reconstructive care.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical context for 21554, typical sites of service, and the service type. The publication also summarizes common billing considerations, frequently used modifiers, and how this code relates to broader surgical and oncology care pathways.

This report provides benchmarks and policy-relevant points for payers and providers, highlighting where 21554 fits within surgical coding hierarchies and operational workflows. It is intended for clinicians, coding professionals, and payer policy staff seeking a national-level briefing on the use and classification of this CPT code.

Billing Code Overview

CPT code 21554 describes an operative procedure in which a surgeon excises a tumor 5 cm or larger located beneath the fascia of the neck or anterior thorax. This procedure involves removal of a sizable deep soft-tissue mass and is classified as a major soft-tissue tumor excision.

Service type: Surgical excision of deep soft-tissue tumor (major soft-tissue surgery)
Typical site of service: Hospital operating room or ambulatory surgical center with appropriate surgical and anesthesia support

Clinical & Coding Specifications

Clinical Context

A 58-year-old patient presents with a progressively enlarging, firm subfascial mass on the anterior chest wall near the sternum that is clinically suspicious for a soft-tissue neoplasm. Preoperative workup includes contrast-enhanced CT of the neck and chest to define depth and relation to underlying structures, ultrasound-guided core biopsy confirming a likely sarcoma or deep benign tumor, and preoperative medical clearance. The patient is scheduled for an operative excision under general anesthesia. Intraoperatively the surgeon makes an incision over the mass, dissects through skin and subcutaneous tissue, elevates the fascia, and performs wide local excision of the tumor measuring 6 cm in greatest dimension located beneath the investing fascia on the anterior thorax. Hemostasis is obtained, deep soft tissues and fascia are repaired as needed, and the skin is closed. Typical site of service is an outpatient or inpatient operating room in a hospital or ambulatory surgery center. The service type is a surgical excision of a deep soft tissue tumor (greater than or equal to 5.0 cm) from the neck or anterior thorax, billed with 21554 and appropriate anesthesia and facility services.
