CPT code 75803: Lymphangiography, bilateral extremities2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 75803 covers

This service is the image interpretation for lymphangiography of both upper or both lower extremities, using x-ray after contrast is introduced into the lymphatic system. Radiologists typically report the professional work when evaluating lymphatic channels; the technical service includes the imaging equipment and staff. The study is performed in radiology settings to assess lymphatic flow or suspected obstruction.

Medicare assigns physician fee schedule status C, so the Medicare Administrative Contractor sets payment for each claim rather than CMS publishing a national payment. The code has professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and billing without a component modifier represents the global service. The code is bilateral; modifier 50 does not increase payment.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
