Updated Median MELD at Transplant scores take effect September 29

Effective September 29, 2021, 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 September 28, this chart shows the current scores and those that will be updated.

The scores are updated twice a year. They are based on recent liver transplants performed 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. Exception scores for other candidates will 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 results remained the same. The MPaT is a national calculation and is the same for all transplant programs with PELD exception candidates. It will remain at 35.
