Chelation Therapy is a title for a treatment which is used in two ways:

  1. Chelation therapy for heavy metal poisoning is covered. Chelating agents are used to bind heavy metals so that they can be excreted from the body in cases of acute (and rarely chronic) poisoning.
  2. Chelation therapy for all other purposes is not covered. No other use of chelation therapy has been shown to be safe and effective in any rigorous scientific way; it is considered experimental and is not a covered service.
Medical Statement

Chelation therapy is infusion of chelating agents for the treatment of the toxic effects of acute (or, rarely chronic) heavy metal poisoning.  There are several heavy metal antagonists utilized such as EDTA, deferoximine (Desferal), dimercaprol (BAL in oil), succimer (Chemet) and penicillamine (Cuprimine, Depen).  Chelation is covered and considered medically appropriate when used for the following:

  • Heavy metal poisoning (cadmium, copper, gold, iron, lead, mercury)
  • Arsenic poisoning
  • Biliary cirrhosis
  • Cooley’s anemia (thalassemia major)
  • Wilson’s disease
  • Sickle cell anemia
  • Secondary hemochromatosis (i.e., due to iron overload from multiple transfusions)
