The median MELD at transplant (MMaT) values, which affect many liver transplant candidates with exception scores, will be updated effective Sept. 27, 2023. The MMaT is based on data about liver transplants performed within a 150 nautical mile radius around the donor hospital where the organ is recovered.
The updated data report displays the newly derived MMaT scores by each donor hospital. The scores are updated twice a year.
The national median PELD at transplant (MPaT) calculation will remain at 33, the same as in the previous cohort made effective in March 2023. (The MPaT is a national calculation, drawing upon transplants performed nationwide, and is not based on the donor hospital).
