CPT® Code 75940

Deleted

The CPT® Code 75940 refers to the procedure involving the percutaneous placement of an inferior vena cava (IVC) filter, which is performed under radiological supervision and interpretation. An IVC filter is a medical device designed to prevent pulmonary embolism, a serious condition that can occur when blood clots from the deep veins of the pelvis or lower extremities migrate to the lungs. The procedure begins with a cavogram, which is a diagnostic imaging study that allows the physician to evaluate the vascular anatomy of the inferior vena cava and to rule out the presence of any thrombus (blood clot) within the vessel before the filter is placed. During the actual placement of the IVC filter, the physician utilizes fluoroscopy or other radiological techniques to ensure that the filter is positioned correctly and deployed effectively within the IVC. After the procedure, the physician reviews the radiographic images obtained during the placement and generates a written report detailing the findings related to the radiological aspects of the procedure. This comprehensive approach ensures both the safety and efficacy of the IVC filter placement, contributing to the overall management of patients at risk for pulmonary embolism.
