CPT® Code 36800

The procedure described by CPT® Code 36800 involves the insertion of a cannula for hemodialysis or other purposes, specifically through a vein-to-vein connection. A cannula is a flexible tube that is inserted into a vein to facilitate the removal and return of blood during hemodialysis, a treatment for kidney failure. In this procedure, two suitable veins are typically selected, with a preference for veins located in the nondominant forearm due to their accessibility and size. The procedure begins with the exposure and incision of the selected blood vessels, allowing for the insertion of one cannula into the first vein and another into the second vein. Once inserted, the cannulas are secured in place using sutures to ensure stability and prevent movement. The distal segments of the selected veins are then ligated, which involves tying off the veins to control blood flow. The two cannulas are connected using synthetic material, which may be partially or completely buried under the skin to protect the connection. During the hemodialysis process, the cannulas are connected to tubing that links directly to the dialysis machine, enabling the efficient exchange of blood for treatment. This procedure is classified as a separate procedure, indicating that it is distinct from other related procedures and is performed specifically for the purpose of establishing access for hemodialysis.
