DESCRIPTION

Siltuximab is a monoclonal antibody that binds the cytokine interleukin-6 (IL-6).  This prevents IL-6 from binding to both soluble and membrane-bound IL-6 receptors.  IL-6 is involved in diverse physiological processes, including coordination of the immune response to infection.  When IL-6 is overproduced by cells within the lymph nodes it contributes to overgrowth of lymphatic cells and other systemic symptoms.

IMPORTANT REMINDER

We develop Medical Policies to provide guidance to Members and Providers.  This Medical Policy relates only to the services or supplies described in it.  The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy.  For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed.  If there is a conflict between the Medical Policy and a health plan, the express terms of the health plan will govern.
