Geographic Units for Organ Distribution

Donated organs are first offered to transplant candidates within the Donation Service Area of the host OPO (with the exception of perfectly matched donor kidneys). If the organs are not acceptable for use in the transplant centers in the host OPO’s DSA, they are offered transplant centers in the Region, then to all centers nationwide. DSA assignations are determined by CMS. (OPTN Glossary May 2021)
