Organ Procurement and Transplantation Network (OPTN)

The OPTN is the national network that operates the U.S. transplant system under federal contract.

The Organ Procurement and Transplantation Network (OPTN) is the unified U.S. transplant network that sets organ-allocation policy, maintains the national waiting list, and operates the computerized system that matches deceased-donor organs to candidates.[1][2] It was created by the National Organ Transplant Act of 1984 (NOTA) and is operated under a federal contract administered by the Health Resources and Services Administration (HRSA), an agency of the U.S. Department of Health and Human Services.[1][2]

The OPTN is not itself a government agency: it is a network of transplant programs, organ procurement organizations, histocompatibility laboratories, and other members, whose mandated functions are carried out by one or more federal contractors under HRSA oversight.[1][2] For most of its history, those functions were performed by a single contractor, the United Network for Organ Sharing (UNOS); since 2023 the network has been moving to a multi-vendor model.[3][4]

Creation and statutory basis

NOTA (Pub. L. 98-507, 1984) directed the Secretary of HHS to establish the OPTN by contract with a private, non-profit entity and prohibited the buying and selling of human organs.[1][5] The OPTN's responsibilities, maintaining a national patient waiting list, operating an equitable matching system, developing allocation policy, and collecting data, derive from NOTA and are detailed in regulation.[5][2]

The OPTN Final Rule (42 CFR Part 121)

Although NOTA created the OPTN in 1984, HHS did not promulgate the implementing regulations until much later. The OPTN Final Rule, codified at 42 CFR Part 121, was published April 2, 1998 but did not become effective until March 16, 2000, after repeated delays driven by congressional appropriations moratoria and disputes over allocation policy and the scope of HHS oversight.[6][7] The Final Rule establishes the OPTN's structure, the policy-development process, performance goals (including reducing geographic inequities in allocation), and the Secretary's authority to review OPTN policies.[7]

How policy is made

OPTN policy is developed through a structured, public process rather than by agency fiat:[2][8]

A Board of Directors and a set of standing committees (organ-specific and functional) draft and review policy.
Proposed policies go out for public comment before adoption.
Final policies are subject to Secretarial review by HHS under 42 CFR §121.4.[9]

This process governs allocation rules (for example, the kidney and liver allocation systems), membership and bylaws, and data-submission requirements binding on members.[2][8]

Modernization (Securing the U.S. OPTN Act, 2023)

For decades the OPTN was operated under a single contract held by UNOS. Following congressional and oversight scrutiny, Congress enacted the Securing the U.S. Organ Procurement and Transplantation Network Act (Pub. L. 118-14), signed September 22, 2023, which amended NOTA to give the Secretary flexibility to award the OPTN's work to multiple vendors rather than a single contractor, and removed a statutory cap on the contract.[3][4][5]

A central element of modernization is the separation of governance from operations. For the first time in the network's history, the OPTN Board of Directors was established as an independent, separately incorporated legal entity, no longer part of UNOS's corporate board; HRSA awarded a board-support contract to the American Institutes for Research to support the newly independent board.[3][4] HRSA, within its Division of Transplantation, leads the modernization initiative and has been awarding the OPTN's component functions (IT/matching, board support, and others) across multiple contractors.[4][10]

As of late 2025, UNOS continued to hold the core OPTN information-technology and matching contract under an extension arrangement with HRSA, while other functions transitioned to HRSA or other vendors.[11][4] (See United Network for Organ Sharing.)

Distinguishing the OPTN from related bodies

The OPTN is frequently confused with the bodies that surround it:[2][10]

HRSA (Division of Transplantation) provides federal oversight of the OPTN and administers its contracts; it is the government side. See HRSA Division of Transplantation.
CMS regulates OPOs and transplant hospitals (certification, conditions of coverage/participation), a separate regulatory track from OPTN policy.
The Scientific Registry of Transplant Recipients (SRTR) is a separate, HRSA-overseen registry that analyzes transplant outcomes and co-produces the annual data report; it is not the policy-making OPTN.
OPOs are members that recover organs in the field; the OPTN allocates them.
