Transcatheter arterial chemoembolization (TACE) is a minimally invasive procedure performed in interventional radiology to restrict a tumor's blood supply. Small embolic particles coated with chemotherapeutic drugs are injected selectively through a catheter into an artery directly supplying the tumor.
Hepatic artery embolization, also known as trans-arterial embolization (TAE), is one of the several therapeutic methods to treat primary liver tumors or metastases to the liver. The embolization therapy can reduce the size of the tumor, and decrease the tumor's impact such its hormone production, effectively decreasing symptoms.
Transarterial bland embolization (TAE, also known as HAE) is a catheter-based tumor treatment of the liver.In this procedure, embolizing agents (e.g., polyvinyl alcohol, gelfoam, acrylic copolymer gelatin particles, embospheres) can be delivered through the tumor's feeding artery in order to completely occlude the tumor's blood supply.
Conventional transarterial chemoembolization (cTACE): Injection of lipiodol with high dose chemotherapy with or without microparticles directly into the tumor-feeding arteries. [18] Drug-eluting bead chemoembolization (DEB-TACE): delivery of microparticles that are themselves loaded with the chemotherapy agent – typically doxorubicin or ...
Therefore, locoregional therapies such as transarterial chemoembolization or radioembolization, can selectively be administered in the arteries that are supplying the tumors and will preferentially lead to deposition of the particles in the tumor, while sparing the healthy liver tissue from harmful side effects.

The CPT code revisions in 2013 were part of a periodic five-year review of codes. Some psychotherapy codes changed numbers, for example 90806 changed to 90834 for individual psychotherapy of a similar duration. Add-on codes were created for the complexity of communication about procedures.

Embolization refers to the passage and lodging of an embolus within the bloodstream. It may be of natural origin (pathological), in which sense it is also called embolism, for example a pulmonary embolism; or it may be artificially induced (therapeutic), as a hemostatic treatment for bleeding or as a treatment for some types of cancer by deliberately blocking blood vessels to starve the tumor ...
