What 75820 covers
This service covers the radiologist’s imaging supervision and interpretation of a contrast venogram of one extremity. A clinician introduces contrast into the arm or leg veins, and radiographic images show the venous anatomy and blood flow. It may be performed to evaluate suspected venous obstruction or define the veins before a planned intervention. Radiologists and interventional radiologists commonly interpret these studies in hospital and outpatient imaging settings.
Select the code for a study of one arm or one leg; a bilateral extremity study is reported differently. The record should identify the imaged extremity and include the images and interpretation supporting the diagnostic findings. The injection procedure may be reported separately when performed and supported. Modifier 26 identifies the interpretation, while modifier TC identifies the equipment and staff; without either modifier, the code represents the global service. When multiple cardiovascular diagnostic procedures are reported, the CMS multiple-procedure reduction applies to the technical component.
