CPT® Code 34471

Thrombectomy is a surgical procedure aimed at removing a thrombus, or blood clot, from a blood vessel. In the case of CPT® Code 34471, the procedure specifically targets the subclavian vein, which is located beneath the collarbone. The thrombectomy can be performed directly or with the assistance of a catheter, and it involves making an incision in the neck to access the affected area. The formation of a thrombus typically occurs in regions of the vein that are narrowed or stenotic, leading to potential complications such as impaired blood flow. During the procedure, the surgeon makes an incision to expose the vein and gain access to the thrombus. To manage blood flow during the operation, vessel loops are placed both upstream and downstream of the thrombus. The surgeon then incises the vein and removes the thrombus through direct exposure. Alternatively, if a catheter is used, a balloon catheter may be inserted through a venotomy at a location beyond the thrombus. This catheter is advanced past the clot, inflated, and then withdrawn, effectively capturing and removing the thrombus. After the thrombus has been successfully removed, a venography may be conducted to confirm that the entire clot has been eliminated and that the vein is open and functioning properly. It is important to use the correct CPT® code, 34471, for this specific procedure involving the subclavian vein via a neck incision, while 34490 should be used for similar procedures involving the axillary vein through an arm incision.
