CPT code 43122 identifies a partial esophagectomy with reconstruction, commonly used for surgical management of esophageal disease including malignancy and select benign conditions. This code is important nationally because it captures high-acuity surgical care with significant resource use, perioperative risk, and implications for inpatient reimbursement and quality reporting. Payers commonly involved in coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of the clinical intent of the code, the typical inpatient surgical setting, and the key elements that drive coding and billing such as extent of resection and surgical approach. The publication outlines benchmarks for utilization and reimbursement where available, highlights policy considerations relevant to coverage and prior authorization, and provides clinical context to support correct code selection. Data not available in the input will be noted as such; the document focuses on national-level implications for hospitals, surgical teams, and revenue cycle stakeholders rather than state-specific rules.
