Summary & Overview
CPT 38589: Unlisted Procedure, Lymphatic System
CPT code 38589 designates an unlisted procedure of the lymphatic system and is used when no specific CPT code accurately describes the performed lymphatic intervention. As an unlisted lymphatic procedure code, 38589 matters nationally because it is the billing pathway for uncommon, novel, or highly individualized lymphatic surgeries and interventions that lack a discrete code. Proper documentation and operative detail are essential for coverage review and claims processing.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise overview of the clinical scope of the code, payer coverage context, common modifiers seen with unlisted procedure reporting, and operational considerations for submitting claims based on the code’s nature. The publication outlines benchmarks and policy themes relevant to unlisted procedure reporting, explains when 38589 is typically applied, and summarizes documentation elements payers commonly require for adjudication.
This resource is intended for national audiences involved in surgical coding, billing operations, and compliance oversight, offering clear context on when CPT code 38589 is used and what to expect in payer review and claim adjudication for unlisted lymphatic procedures.

Clinical & Coding Specifications
Clinical Context
A 62-year-old patient presents with a persistent, unexplained axillary mass and intermittent upper extremity lymphedema following prior oncologic surgery. Imaging (ultrasound and MRI) suggests a lymphatic abnormality not addressed by standard, reportable lymph node procedures. The surgical team performs an unlisted lymphatic procedure to excise an aberrant lymphatic channel and repair damaged lymphatic tissue to relieve symptoms and obtain tissue for pathology. Typical workflow includes preoperative evaluation by a surgical oncologist or vascular surgeon, informed consent describing the unlisted nature of the procedure, intraoperative lymphatic mapping or identification using dye or magnification, excision/repair of the lymphatic abnormality, and postoperative pathology and lymphedema management referral. Typical site of service is an outpatient surgical center or hospital operating room. The service type is a surgical procedure of the lymphatic system that does not have an existing specific CPT code and is reported using 38589.
