CPT code 38380 represents surgical repair of the cervical thoracic duct via neck incision, typically performed to control chyle leak or repair penetrating trauma to the chest. This is a relatively specialized, infrequent procedure with implications for surgical, trauma, and inpatient care pathways nationwide. It matters because accurate coding supports appropriate surgical case classification, resource allocation in operating rooms and inpatient units, and coordination between surgical and critical care teams.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context describing the procedure and typical settings, an outline of which payers commonly cover this service, and what to expect in claims handling and coding classification. The publication also provides benchmarks and policy-relevant notes where available, plus guidance on typical sites of service and service line implications.

This summary is intended to help coders, billing managers, and clinical leaders understand the national coding meaning and administrative considerations of CPT code 38380 so they can align documentation, operative reporting, and billing workflows with payer expectations and hospital resource planning.
