Summary & Overview
CPT 43340: Esophagectomy with Partial Gastrectomy and Reconstruction
CPT code 43340 represents an open esophagectomy performed through an abdominal incision with removal of the diseased esophagus and partial gastrectomy followed by reconstructive anastomosis to restore gastrointestinal continuity. As a major surgical oncology and gastrointestinal procedure, it carries significant clinical and resource implications for hospitals, surgical teams, and payers nationwide. This code is relevant for complex perioperative management, inpatient utilization, and bundled payment considerations.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, common billing modifiers and typical sites of service, plus national benchmarking and coverage considerations where available. The publication outlines expected service lines, typical inpatient settings, and the clinical rationale for using this specific CPT code in claims.
The report also highlights what to look for in documentation to support the code selection and the aspects of care that drive utilization and reimbursement. Data not available in the input is indicated where applicable. This summary is intended to orient clinicians, coders, and policy analysts to the primary uses and implications of CPT code 43340 at a national level.
Billing Code Overview
CPT code 43340 describes an open surgical procedure in which the provider removes the diseased esophagus and part of the stomach through an abdominal incision, then reconstructs the gastrointestinal tract by connecting the remaining stomach and esophagus to reestablish continuity. This procedure is a major thoracoabdominal gastrointestinal surgery focused on resection of the esophagus with partial gastrectomy and immediate reconstruction.
-
Service type: Major surgical resection and reconstruction of the upper gastrointestinal tract
-
Typical site of service: Inpatient hospital operating room with postoperative inpatient recovery
Clinical & Coding Specifications
Clinical Context
A typical patient is a 60- to 75-year-old individual with advanced esophageal disease such as high-grade esophageal adenocarcinoma, corrosive stricture, or long-segment, symptomatic Barrett-related dysplasia refractory to endoscopic therapy. The patient presents with progressive dysphagia, weight loss, odynophagia, and possible aspiration. Diagnostic workup includes endoscopy with biopsy, cross-sectional imaging (CT chest/abdomen), nutritional assessment, pulmonary evaluation, and cardiology clearance. Neoadjuvant chemotherapy and/or radiation may be administered for cancer patients per multidisciplinary tumor board recommendations. On the day of surgery the patient is admitted to an inpatient surgical unit, undergoes general anesthesia, and receives perioperative antibiotics and thromboprophylaxis. The operating surgeon performs an open transabdominal esophagectomy with partial gastrectomy and reconstruction (commonly a gastric pull-up with cervical or intrathoracic anastomosis), ensures hemostasis, places appropriate drains, and coordinates postoperative critical care, including enteral feeding access, pain control, pulmonary hygiene, and staged mobilization. Typical recovery includes an initial ICU or step-down stay, imaging to evaluate anastomotic integrity (contrast swallow) before initiating oral intake, and ongoing oncologic follow-up when applicable.
