What is the coding designation for embolization that completely closes a vessel?

The coding designation for embolization that completely closes a vessel is specifically referred to as occlusion. In medical coding, occlusion denotes the process by which a vessel is obstructed or closed off, which aligns with the context of embolization where the intention is to halt blood flow through a specific vessel.

Embolization encompasses various procedures aimed at blocking a blood vessel, often for treating conditions like tumors or abnormal blood vessel formations. When the procedure results in complete closure of the vessel, it is critical to use the term "occlusion" as it accurately describes the end result of the embolization.

In contrast, the other terms do not capture the specific intent and outcome of completely closing a vessel. For example, vessel sealing code generally refers to techniques for sealing vessels without implying a complete closure. Similarly, embolization procedure is a broader term that does not specify the outcome of the closure, and the term complete closure code is not a recognized code descriptor in the coding guidelines.

Therefore, the designation is best captured by the term occlusion, reflecting the comprehensive closure of the vessel due to the embolization procedure.
