CPT® Code 36835

The procedure described by CPT® Code 36835 involves the insertion of a Thomas shunt, which is a specialized device used to facilitate long-term access to the vascular system for patients undergoing hemodialysis. This procedure is particularly important for individuals who require frequent dialysis treatments, as it provides a reliable and efficient means of accessing the bloodstream. The Thomas shunt consists of two silastic cannulas, which are flexible tubes designed to minimize irritation to the surrounding tissues, and a Dacron patch that enhances the stability and integration of the shunt with the vascular structures. The insertion process requires careful surgical technique, including the creation of small incisions over the femoral artery and vein, allowing for direct access to these major blood vessels. By suturing the Dacron patches to the artery and vein, the procedure ensures that the cannulas remain securely in place, preventing occlusion and maintaining patency for future dialysis sessions. The external components of the shunt are designed to be easily connected and disconnected from hemodialysis equipment, making the process of dialysis more efficient and less invasive for the patient.
