Organ Procurement and Transplantation Network (OPTN) policies are rules that govern operation of all UNOS member transplant hospitals, organ procurement organizations (OPOs) and histocompatibility labs in the U.S. Policies are made through a collaborative process involving committees, the OPTN Board of Directors and the public. View these policies now or view policy brochures.

Framework for organ distribution

Organ distribution
