CPT code 43101 represents a surgical removal of an esophageal lesion via a thoracic or abdominal incision. This operative approach is used when lesions cannot be managed endoscopically or when a more extensive resection is required. Nationally, the code is relevant for surgical departments, payers, and policy stakeholders because it signals higher resource use, inpatient surgical care, and potential implications for operative risk and post‑operative care pathways.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payment and utilization benchmarks where available, common clinical contexts for using the code, and administrative considerations for claim submission. Readers will find summaries of expected sites of service and service type, guidance on how this code fits into surgical care episodes, and where to look for supporting documentation and diagnosis linkage.

The content is intended for a national audience of coding professionals, surgical providers, billing managers, and payer policy analysts who need a concise reference for clinical meaning, billing context, and what to expect when this code appears on a claim. Data not available in the input will be noted rather than inferred.
