Summary & Overview

CPT 43045: Thoracic Approach for Esophageal Foreign Body Removal

CPT code 43045 denotes an open thoracic surgical approach to remove a foreign body from the esophagus. This operative code is used when less invasive methods such as endoscopy are unsuccessful or not feasible, and it represents a higher-acuity surgical intervention with associated inpatient and perioperative resource use. Nationally, use of this code signals complex esophageal foreign-body management that can impact hospital surgical workload, anesthesia resources, and postoperative care requirements.

Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical and billing context for the code, typical sites of service, and which payer populations are most relevant. The publication provides benchmark considerations, common modifier usage where available, and notes on typical care settings and clinical circumstances prompting use of the code. It also identifies areas where input data is not available and directs readers to clinical guidelines and payer policies for coverage specifics.

Billing Code Overview

CPT code 43045 describes a surgical procedure in which the provider makes an incision into the thorax (chest) to access the esophagus for removal of a foreign body. This procedure is an operative service performed to extract an object that cannot be removed endoscopically or by less invasive means.

Service type: Surgical extraction of foreign body from the esophagus via thoracotomy (open chest approach)
Typical site of service: Inpatient operating room or surgical suite within a hospital setting

Clinical & Coding Specifications

Clinical Context

A 45-year-old male presents to the emergency department after accidentally swallowing a large, sharp piece of bone that becomes lodged in the mid-thoracic esophagus. He has progressive odynophagia, inability to swallow secretions, and intermittent chest pain. Initial evaluation includes airway assessment, upright chest radiograph, and flexible endoscopy; endoscopic retrieval attempts are unsuccessful because the foreign body is deeply embedded and causing mucosal perforation risk. The surgical team is consulted and recommends a transthoracic approach. The patient is brought to the operating room, receives general endotracheal anesthesia, and is positioned for a right thoracotomy. The surgeon makes a chest incision, dissects to the esophagus, controls the field, removes the foreign body, repairs any esophageal injury, irrigates, places drains as indicated, and closes the chest. Postoperative care includes intensive monitoring for leak, chest tube management, intravenous antibiotics, pain control, and evaluation with esophagram prior to initiating oral intake.
