For transplant hospitals
Changes: Pending and implemented
New policies require candidates to meet medical eligibility criteria to be eligible for a required kidney share on the heart or lung match.
The required share threshold for simultaneous liver-kidney (SLK) allocation has expanded from 250 nautical miles to 500 nautical miles for eligible adult candidates (e.g., Status 1A or MELD of 29 or greater).
The Organ Procurement and Transplantation Network Ad-hoc Multi Organ Transplantation Committee has implemented several safety net policies to ensure patients in need of multiple organ transplants to get priority when they become medically eligible.

OPTN, UNOS and SRTR
- The Organ Procurement and Transplantation Network, or OPTN, is a public-private partnership that links all professionals involved in the U.S. donation and transplantation system. It is a member organization that acts through its Board of Directors and volunteer committees. The OPTN board establishes and maintains transplant policies and bylaws. Learn more about the OPTN.
- UNOS is the non-profit that serves as the OPTN under contract with the federal government, and convenes the community to develop policies together. UNOS manages the national transplant waiting list and maintains the database that contains all organ transplant data for every transplant event in the U.S. Learn more about UNOS and its role as the OPTN.
- The Scientific Registry of Transplant Recipients, or SRTR, operates under contract with the federal government. The SRTR works with UNOS as the OPTN contractor and provides analytic support in policy development and performance monitoring. The SRTR evaluates the performance of the system through regular publication of reports. Learn more about SRTR.
