Summary & Overview
CPT 75803: Supervision and Interpretation of Bilateral Extremity Lymphatic Imaging
CPT code 75803 represents the supervision and interpretation of radiologic imaging of the lymphatic system for both extremities (either bilateral arms or bilateral legs). This code defines a diagnostic imaging professional service focused on evaluation of lymphatic anatomy and function across both sides of a pair of extremities. Nationally, lymphatic imaging is an important tool for diagnosing lymphedema, staging lymphatic disorders, and guiding therapeutic decisions in vascular and oncology care pathways.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and reimbursement policies for bilateral lymphatic imaging supervision and interpretation can affect access to specialized diagnostic evaluations and downstream management plans.
Readers will learn the clinical context for use of CPT code 75803, typical sites of service where it is performed, and which major national payers are relevant to coverage discussions. The publication provides benchmarks and policy-relevant updates where available, clarifies coding scope and appropriate clinical scenarios for application, and situates the code within diagnostic imaging workflows for lymphatic disorders. Data not available in the input will be clearly noted in detailed sections.
Billing Code Overview
CPT code 75803 describes supervision and interpretation of radiologic imaging of the lymphatic system of the extremities on both sides, covering either the bilateral arms or the bilateral legs. The service involves overseeing and interpreting imaging studies that evaluate lymphatic anatomy and function in both extremities.
-
Service type: Diagnostic radiologic supervision and interpretation of bilateral extremity lymphatic imaging
-
Typical site of service: Hospital radiology departments, outpatient imaging centers, or specialized vascular/lymphatic imaging suites
Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old woman with unilateral limb swelling and a history of breast cancer with axillary lymph node dissection presenting to the outpatient radiology department for diagnostic lymphoscintigraphy of both upper extremities. The procedure is ordered to evaluate lymphatic drainage, detect lymphatic obstruction or lymphedema, and guide therapeutic planning. The clinical workflow includes: referral by the oncologist or lymphedema therapist; pre-procedure consent and explanation; intradermal or subcutaneous injection of radiotracer at standardized sites on each hand; dynamic and delayed gamma camera imaging of both arms; image acquisition supervised by the interpreting physician; and formal interpretation with a written report. Results are communicated to the referring provider and used to plan compression therapy, manual lymphatic drainage, or surgical referral.

| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when billing only the physician interpretation/supervision portion separate from technical imaging services. |
TC | Technical component | Use when billing only the technical component (equipment, technologist) and not the professional interpretation. |
