Summary & Overview

CPT 43108: Esophagectomy via Non-Thoracotomy with Bowel Graft Reconstruction

CPT code 43108 denotes removal of most or all of the esophagus via a non-thoracotomy approach with reconstruction using a small bowel or colon graft. This complex operative code captures high-acuity, resource-intensive care for patients with esophageal disease requiring esophageal resection and reconstruction. It is nationally relevant because it represents procedures with significant inpatient resource use, perioperative risk, and implications for surgical coding, case mix, and payment across major payers.

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 and coding context for CPT code 43108, benchmarks for utilization and payment where available, common billing and documentation considerations, and policy updates that affect coverage and coding practice. The publication also outlines expected sites of service and service type to assist clinical, coding, and revenue teams in classifying claims accurately.

Intended readers will gain a clear understanding of when CPT code 43108 applies, the clinical scope of the procedure, and the types of analyses and policy topics that commonly surround high-complexity esophagectomy claims. Data not available in the input will be noted where relevant.

Billing Code Overview

CPT code 43108 describes the surgical removal of most of or the entire esophagus by an approach other than thoracotomy with reconstruction using a small bowel or colon graft. This procedure is a major esophagectomy with non-thoracotomy approach and bowel graft reconstruction.

Service type: Surgical — Major Thoracic/Upper Gastrointestinal Surgery

Typical site of service: Inpatient hospital operating room

Clinical & Coding Specifications

Clinical Context

A 64-year-old male with mid-to-distal esophageal squamous cell carcinoma presents after staging that demonstrates localized disease without unresectable metastases. After multidisciplinary tumor board review, the patient is scheduled for an esophagectomy via a non-thoracotomy approach (transhiatal or laparoscopic abdominal plus cervical incision) with reconstruction using a colon interposition graft because the stomach is unavailable or unsuitable due to prior gastrectomy or radiation. The clinical workflow includes preoperative optimization (nutrition, pulmonary evaluation, anesthesia assessment), intraoperative steps (abdomen and neck exposure, resection of most or all of the esophagus, harvest and mobilization of a segment of colon or small bowel graft, creation of an anastomosis in the neck or chest), and postoperative care (ICU monitoring, enteral nutrition via jejunostomy tube if placed, pain control, swallow study prior to oral intake, and surveillance for complications such as anastomotic leak, graft ischemia, or strictures). Documentation should specify approach (non-thoracotomy), extent of esophagectomy, conduit used (colon or small bowel), anastomosis location, and any intraoperative complications to support accurate coding with 43108 and appropriate modifiers.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`C15.9`	Malignant neoplasm of esophagus, unspecified	Primary indication for esophagectomy when tumor location and staging warrant resection.
`C15.3`	Malignant neoplasm of upper third of esophagus	Tumors in this location may require non-thoracotomy approaches with cervical anastomosis and possible colon interposition.
`C15.4`	Malignant neoplasm of middle third of esophagus	Common tumor location necessitating esophagectomy and conduit reconstruction.
`C15.2`	Malignant neoplasm of lower third of esophagus	Lower esophageal tumors may require esophagectomy; stomach may be unavailable prompting colon graft.
`K22.2`	Barrett esophagus with dysplasia	Precursor lesion that can progress to cancer and sometimes lead to esophagectomy in multifocal or refractory disease.
