Updated median MELD at transplant scores in effect March 26; median PELD at transplant score unchanged

Published on: Wednesday, March 26, 2025

Effective March 26, 2025, the liver median MELD at transplant (MMaT) values have been updated for each donor hospital nationwide. The MMaT serves as an index value for most liver transplant candidates with MELD exception scores. The updated data table of MMaT by donor hospital is available on the Liver and Intestine resource page of the OPTN website. The previous data table of MMaT values (in effect through March 25, 2025) is available for comparison.

The median PELD at transplant (MPaT) value will remain at 31, unchanged from the one previously in effect. The MPaT calculation is based on transplants performed nationwide and is not affected by the location of the donor hospital.

Many MELD exception candidates for liver transplants have their exception score based on the MMaT of the donor hospital where the match is being run (for example, MMaT minus 3 points). This means that MELD exception scores will fluctuate based on liver offers from different donor hospitals, and the specific assigned score will not be known until the match is run for an individual donor.

A frequently asked questions (FAQ) document is available on the Liver and Intestine resource page of the OPTN website, addressing the MMaT policy. A recorded webinar from June 2022 also features a presentation about the MMaT and MPaT and responses to questions from participants.
