CPT® Code 36228

Add-On Code

Selective catheter placement, each intracranial branch of the internal carotid or vertebral arteries, unilateral, with angiography of the selected vessel circulation and all associated radiological supervision and interpretation (eg, middle cerebral artery, posterior inferior cerebellar artery) (List separately in addition to code for primary procedure)

Selective catheter placement refers to a specialized procedure where a catheter is inserted into specific branches of the internal carotid or vertebral arteries, which are major blood vessels supplying the brain. This procedure is particularly focused on the intracranial branches, such as the middle cerebral artery and the posterior inferior cerebellar artery, among others. The term "selective" indicates that the catheter is directed to a specific area of interest rather than being placed in a more general location. During this process, a guidewire is first advanced into the targeted artery, followed by the catheter. Once the catheter is in place, radiopaque contrast media is injected to enhance the visibility of the blood vessels during imaging. This allows for detailed angiography, which is the imaging of blood vessels, to assess the circulation within the selected artery. The procedure includes comprehensive radiological supervision and interpretation to ensure accurate results. After the angiography is completed, the catheter is removed, and a detailed report of the findings is generated. It is important to note that this code, CPT® 36228, is reported separately in addition to the code for the primary procedure performed, emphasizing its role in providing a thorough evaluation of the vascular structures in the brain.
