Effective March 31, the median MELD at transplant (MMaT) for liver candidates with exception scores will be updated. The updated table lists the MMaT for each liver transplant hospital that will be in effect as of that date, as well as the details of the MMaT calculation.
If you wish to compare the new MMaT to the values current through March 30, this table lists the current scores that will be updated.
The scores are updated twice a year. They are based on recent liver transplants at all liver transplant hospitals within a 250 nautical mile radius of the hospital listing the exception candidate, with exclusions based on certain candidates and procedure types.
Many individual candidates’ exception score will remain the same as it was under the previous calculation. Other candidates will have their exception score either increase or decrease. As always, transplant programs may request individual exception scores for candidates by the procedure set forth in OPTN Policy 9.4 (MELD or PELD Score Exceptions).
The Median PELD at Transplant (MPaT) was recalculated using updated data but remains the same. MPaT is the same for all transplant programs with PELD exception candidates and will remain at 35.
