OPTN policies are rules that govern operation of all member transplant hospitals, organ procurement organizations (OPOs) and histocompatibility labs in the U.S. Policies are made through a collaborative process involving committees, the board of directors and the public.

All 20 policy sections are contained in one PDF (3 MB). Once you open the document, you can navigate to the section you need by clicking on the table of contents.
