Financial facts

UNOS fulfills a broad mission and vision. A key component of our mission is to serve as the Organ Procurement and Transplantation Network (OPTN) under federal contract. The OPTN contract represents the largest source of UNOS’ revenue and expenses.

In addition, with corporate funding, UNOS provides key value-added services and resources beyond the scope of the OPTN. These initiatives benefit a wide range of people nationwide, including:

  • Clinicians and professionals involved in organ donation and transplantation
  • Potential or active transplant candidates and their caregivers
  • Transplant recipients
  • Potential or actual living organ donors
  • Medical and public health researchers
  • Members of the public interested in organ donation and transplantation

The OPTN is a combined cost-sharing and cost reimbursement contract. For Fiscal Year 2024, the federal government is projected to provide $6.5 million in direct appropriations.  The rest of the OPTN’s revenue comes in the form of a registration fee paid by an OPTN member institution when listing a person as a transplant candidate. For Fiscal Year 2024, the OPTN registration fee will be $868.

UNOS is a non-profit, 501(c)(3) charitable organization. Some of UNOS’ non-OPTN activity is funded through charitable contributions and in-kind charitable support. (Learn more about giving to support UNOS). Other corporate funding sources include registration fees for UNOS events and services, as well as a UNOS fee based on the number of new candidates at each transplant hospital. For Fiscal Year 2024, the UNOS registration fee will be $137.
